    The term of Culture of the Radiological Protection means the way in which the radiological protection is founded, regulated, managed, preserved and perceived in the job places, with the use of the ionizing radiations, in the industry, in medicine and in any daily activity that reflects the activities, beliefs, perceptions, goals and values that all the involved parts concern in relation to the radiological protection. The principles to establish a culture of the radiological protection that should be established by the professionals of the radiological protection, following the recommendations of the International Radiological Protection Association (IRPA) are presented.

    The increased use of ionization radiation for diagnostic and therapeutic purposes, the rapid advances in computed tomography as well as the high radiation doses delivered by interventional procedures have raised serious safety and health concerns for both patients and medical staff and have necessitated the establishment of a radiation protection culture (RPC) in every Radiology Department. RPC is a newly introduced concept. The term culture describes the combination of attitudes, beliefs, practices and rules among the professionals, staff and patients regarding to radiation protection. Most of the time, the challenge is to improve rather than to build a RPC. The establishment of a RPC requires continuing education of the staff and professional, effective communication among stakeholders of all levels and implementation of quality assurance programs. The RPC creation is being driven from the highest level. Leadership, professionals and associate societies are recognized to play a vital role in the embedding and promotion of RPC in a Medical Unit. The establishment of a RPC enables the reduction of the radiation dose, enhances radiation risk awareness, minimizes unsafe practices, and improves the quality of a radiation protection program. The purpose of this review paper is to describe the role and highlight the importance of establishing a strong RPC in Radiology Departments with an emphasis on promoting RPC in the Interventional Radiology environment.

    The International Commission on Radiological Protection (ICRP) has established Task Group 94 (TG94) to develop a publication to clarify the ethical foundations of the radiological protection system it recommends. This TG identified four core ethical values which structure the system: beneficence and non-maleficence, prudence, justice, and dignity. Since the ICRP is an international organization, its recommendations and guidance should be globally applicable and acceptable. Therefore, first this paper presents the basic principles of the ICRP radiological protection system and its core ethical values, along with a reflection on the variation of these values in Western and Eastern cultural traditions. Secondly, this paper reflects upon how these values can be applied in difficult ethical dilemmas as in the case of the emergency and post-accident phases of a nuclear power plant accident, using the Fukushima case to illustrate the challenges at stake. We found that the core ethical values underlying the ICRP system of radiological protection seem to be quite common throughout the world, although there are some variations among various cultural contexts. Especially we found that 'prudence' would call for somewhat different implementation in each cultural context, balancing and integrating sometime conflicting values, but always with objectives to achieve the well-being of people, which is itself the ultimate aim of the radiological protection system.

  5. Evolution of the system of radiological protection

    The development of new radiological protection recommendations by the International Commission on Radiological Protection (ICRP) continues to be a strategically important undertaking, both nationally and internationally. With the growing recognition of the importance of stakeholder aspects in radiological protection decision making, regional and cultural aspects have also emerged as having potentially significant influence on how protection of the public, workers and the environment are viewed. Differing cultural aspects should therefore be considered by the ICRP in its development of new recommendations. Based on this assumption, the NEA organised the Asian Regional Conference on the Evolution of the System of Radiological Protection to express and explore views from the Far East. Held in Tokyo on 24-25 October 2002, the conference included presentations by the ICRP Chair as well as by radiological protection experts from Japan, the Republic of Korea, China and Australia. The distinct views and needs of these countries were discussed in the context of their regional and cultural heritages. These views, along with a summary of the conference results, are presented in these proceedings. (author)

    One of the main challenges facing radiological protection experts is how to integrate radiological protection within modern concepts of and approaches to risk governance. It is within this context that the International Commission on Radiological Protection (ICRP) decided to develop new general recommendations to replace its Publication 60 recommendations of 1990. In the process of developing these new recommendations, the views of the ICRP have evolved significantly, largely due to stakeholder involvement that has been actively solicited by the ICRP. In this regard, it was upheld during the First Asian Regional Conference organised by the NEA in October 2002 that the implementation of the new system must allow for regional, societal and cultural differences. In order to ensure appropriate consideration of these differences, the NEA organised the Second Asian Regional Conference on the Evolution of the System of Radiological Protection. Held in Tokyo on 28-29 July 2004, the conference included presentations by the ICRP Chair as well as by radiological experts from Australia, China, Japan and Korea. Within their specific cultural and socio-political milieu, Asia-Pacific and western ways of thought on how to improve the current system of radiological protection were presented and discussed. These ways of thinking, along with a summary of the conference results, are described in these proceedings. (author)

  7. From regulations towards radiation protection culture

    Boehler, M.C.

    1996-01-01

    Compliance with the technical standards and specifications is a necessary but not sufficient condition for quality in radiation protection. Reaching this quality objective is not a matter of forcing improvements by a regulatory policy of reducing dose limits, but of promoting a real radiation protection culture. The spread of such a radiological protection culture encourages the deliberate adoption in everyday practice of behaviour likely to reduce exposure to ionizing radiation as loser as reasonably achievable. The aim of this paper is to demonstrate that the need to diffuse a radiological protection culture is inspired by the philosophy behind the system recommended by ICPR Publication 60 on the management of residual radiological risk and, in particular by the behavioural and incentive approach implied by the optimization principle. Special attention will be given to the fundamentals likely to contribute in a definition of radiation protection culture. (author)

    1996-01-01

    In order to encourage a high degree of radiation protection of workers and members of public, the relevant authorities and operators in the nuclear industry should urge those responsible for radiation protection to do more than is required bu the pure and simple application of the regulations related to dose limitation compliance with the technical standards and specifications a necessary but not sufficient condition for quality in radiation protection. Reaching this quality objective is not a matter of forcing improvements bu a regulatory policy of reducing dose limits, but of promoting a real radiation protection culture based on an approach of optimizing the radiation protection formalized at the lightest level of the company structure, as well as on the professionalism individual responsibility, motivation and the freely consented to and understood participation of those involved in implementing this policy. The spread of a radiation protection culture encourages the deliberate adoption in everyday practice of behaviour likely to reduce exposure to ionizing radiation, as law as reasonably achievable, and to give life to the 'spirit' of the regulations in the best conditions. This article intends to show that the need to diffuse a radiation protection culture, particularly based on the principle of optimization, is inspired both by the philosophy behind the system recommended by the behavioural and incentive approach implied by the optimization principle. Special attention will be given to the fundamentals likely to contribute in a definition of radiation protection culture. (author)

    This project focuses on the interventional radiology. The main objective of this project work was to provide a guidance and advice for occupational exposure and hospital management to optimize radiation protection safety and endorse safety culture. It provides practical information on how to minimize occupational exposure in interventional radiology. In the literature review all considerable parameters to reduce dose to the occupationally exposed are well discussed. These parameters include dose limit, risk estimation, use of dosimeter, personal dose record keeping, analysis of surveillance of occupational dose, investigation levels, and proper use of radiation protection tools and finally about scatter radiation dose rate. In addition the project discusses the ways to reduce occupational exposure in interventional radiology. The methods for dose reduction are minimizing fluoroscopic time, minimizing the number of fluoroscopic image, use of patient dose reduction technologies, use of collimation, planning interventional procedures, positioning in low scattered areas, use of protective shielding, use of appropriate fluoroscopic imaging equipment, giving training for the staff, wearing the dosimeters and know their own dose regularly, and management commitment to quality assurance and quality control system and optimization of radiation protection of safety.

    Interventional radiology (IR) reduces the need for many traditional interventions, particularly surgery, so reducing the discomfort and risk for patients compared with traditional systems. IR procedures are frequently performed by non-radiologist physicians, often without the proper radiological equipment and sufficient knowledge of radiation protection. Levels of doses to patients and staff in IR vary enormously. A poor correlation exists between patient and staff dose, and large variations of dose are reported for the same procedure. The occurrence of deterministic effects in patients is another peculiar aspect of IR owing to the potentially high skin doses of some procedures. The paper reviews the use of IR and the radiological protection of patients and staff, and examines the need for new standards for IR equipment and the training of personnel. (author)

    Since the discovery of radiation at the end of the 19. century, the health effects of exposure to radiation have been studied more than almost any other factor with potential effects on human health. The NEA has long been involved in discussions on the effects of radiation exposure, releasing two reports in 1994 and 2007 on radiological protection science. This report is the third in this state-of-the-art series, examining recent advances in the understanding of radiation risks and effects, particularly at low doses. It focuses on radiobiology and epidemiology, and also addresses the social science aspects of stakeholder involvement in radiological protection decision making. The report summarises the status of, and issues arising from, the application of the International System of Radiological Protection to different types of prevailing circumstances. Reports published by the NEA Committee on Radiation Protection and Public Health (CRPPH) in 1998 and 2007 provided an overview of the scientific knowledge available at that time, as well as the expected results from further research. They also discussed the policy implications that these results could have for the radiological protection system. The 2007 report highlighted challenges posed by developments in relation to medical exposure and by intentions to include the environment (i.e. non-human species), within the scope of the radiological protection system. It also addressed the need to be able to respond to a radiological terrorist attack. This report picks up on where the 1998 and 2007 reports left off, and addresses the state of the art in radiological prevention science and application today. It is divided into five chapters. Firstly, following broadly the structural topics from the 1998 and 2007 reports, the more purely scientific aspects of radiological protection are presented. These include cancer risk of low dose and dose rates, non-cancer effects and individual sensitivity. In view of the increasing

    The international system of radiological protection is currently being revised with the aim of making it more coherent and concise. The International Commission on Radiological Protection (ICRP) has published its draft reflections on the system's evolution, and has opened discussions with the radiological protection community in order to seek a broad range of stakeholder input. This open dialogue will help bring about a common level of understanding of the issues at stake and contribute to the evolution of new ICRP recommendations. These proceedings present a significant block of stakeholder input, comprising the views of policy makers, regulators, radiological protection professionals, industry and representatives of both non-governmental and intergovernmental organisations.

    The current radiological protection system, which was established mainly by the ICRP and UNSCEAR, has contributed to the prevention of potential radiological health hazards, and has been a fundamental concept during the development of nuclear energy. Through a detailed discussion regarding the new ICRP recommendations, the world nuclear industry has reached a consensus that the current radiological protection system keeps its integrity in principle although it involves some remaining issues, such as the disposal of radioactive waste. In order to maximize the advantages of nuclear energy while keeping the integrity of radiological protection system, it is essential to address the characteristics of radiation, which is specific to nuclear energy, so that nuclear energy can coexist with other energy sources. The three basic principles of radiological protection (i.e., justification, optimization and dose limits), which were completed in the 1990 recommendations of ICRP, should be retained as the basic concepts for the future radiological protection system in order to maintain the continuity and consistency of the radiological protection system. The radiological protection system can be furthermore developed only by combining the above three principles with best practices extracted from utilities' field experience. The significant reduction of radiation exposures received by members of the public and radiation workers in the field has resulted from the efforts by the world utilities to achieve the optimization. In order to correctly apply the theory to the work practices, it is essential to see how the theory is practically used in the field. Such a process should be also emphasized in the revision work of the IAEA Basic Safety Standards (BSS), which is currently under progress. Integrating the theory in the work practices is the key to the true development of nuclear renaissance, which could lead to the establishment of the nuclear safety regime. (author)

    Full text: This work summarises the main ideas and achievements of the Science and Values in Radiological Protection Workshop that was held on 15-17 January 2008 in Helsinki, Finland. In the view of developing of new radiological applications and emerging scientific phenomena it has been recognized a need to develop a shared understanding of emerging challenges for radiological protection among scientific and regulatory communities, public and other concerned stake holders. In response to this the Committee of Radiation Protection and Public Health of the OECD Nuclear Energy Agency and Radiation and Nuclear Safety Authority of Finland tried to initiate a process of longer-term reflection on scientific and societal issues that might challenge radiological protection in the coming years. Among general issues like radiological policy issues, improvement of understanding between research and policy communities, sharing views on emerging scientific issues, there were addressed several scientific issues, like non-targeted effects, individual sensitivity; and circulatory diseases. The main focus of these discussions was to elaborate potential 'what if' scenarios and propose feasible solutions at various levels. These discussions addressed effects that are not direct and evident consequence of the initial lesions produced at the cellular and DNA level like bystander responses, genomic instability, gene induction, adaptive responses and low dose. Particular interest was paid to an extrapolation of risk estimates to low doses and role of Linear Non-Threshold theory in setting regulatory principles. Individual radio-sensitivity and identification of genes that are suspected of having an influence on it were also discussed in one of the Breakout Sessions. Another Breakout Session addressed circulatory diseases. There is emerging evidence in the A-bomb survivors and in other exposed groups that ionising radiation also causes other diseases than cancer, such as circulatory

    Since they were created in 1973 and 1988 respectively, the Superior Center of Nuclear Studies (CSEN) of the Peruvian Institute of Nuclear Energy (IPEN), together with the Peruvian Radioprotection Society (SPR) have carried out different training courses on radiological protection so that people can work safely with ionizing radiations in medicine, industry and investigation. Additionally, radiological protection is taught to pre graduate students of Medical Technology in four Universities. These courses are a must since national regulations demand that people working with ionizing radiations have an authorization, which is granted by the Technical Office of the National Authority - the technical organ of IPEN - after the candidate demonstrates that he or she knows the specific use of the technique using radiations, as well as all aspects related to safety and radiological protection. The analysis of the radiological protection programs is presented in this document. These programs were carried out by CSEN, during the last 30 years, and by the SRP, and they allowed the training of more than 2200 and 1500 people in the country, respectively. The content of both courses is aimed at specific work with radiations (diagnostic radiology, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear gauges, gamma irradiator, etc..) and fulfill the regulatory requirements. The Universities have different programs on radiological protection for the students of Medical Technology. (Author)

    2004-01-01

    At the end of the 1990's, the International Commission on Radiological Protection (ICRP) launched a process for establishing new recommendations, which are expected to serve as guidelines for national systems of radiological protection. Currently the ICRP's proposed recommendations are being subjected to extensive stakeholder comment and modifications. The NEA Committee on Radiation Protection and Public Health (CRPPH) has been actively involved in this process. Part of the Committee's work has been to undertake collaborative efforts with the ICRP through, for example, the organisation of broad stakeholder fora. The first of these, held in Taormina, Italy in 2002, focused on the development of a policy basis for the radiological protection of the environment. The second forum, held in Lanzarote, Spain in April 2003, addressed the latest concepts and approaches in the ICRP proposed recommendations for a system of radiological protection. During this meeting, the ICRP listened to the views of various stakeholder groups, including radiological protection regulators, environmental protection ministries, the nuclear power industry and NGOs. As a result, the ICRP modified its proposals to better reflect stakeholder needs and wishes. This report presents the outcomes of the discussions, examining what the ICRP proposed and how its proposals have been affected and modified as a result of stakeholder input. (author)

    The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

    1983-01-01

    Because of the high growth rate of cell systems in phases of radiation exposure radiological investigations on children should not be considered unless there is a strong indication. The National Council on Radiation Protection and Measurements has worked out recommendations on radiation protection which have been published as an NCRP report. This report is most important even outside the USA. The present translation is aimed to contribute to better understanding of the bases and aims of radiation protection during radiological investigations on children. It addresses not only those physicians who carry out radiological investigations on children themselves but also all physicians requiring such investigations. For these physicians, but also for parents who are worried about the radiation risk to their children the report should be a useful source of information and decision aid ensuring, on the one hand, that necessary radiological investigations are not shunned for unjustified fear of radiation and that, on the other hand, all unnecessary exposure of children to radiation is avoided. Thus, it is to be hoped, the quality of pediatric radiological diagnostics will be improved. (orig./MG) [de

    The objective of this study was to know the professionals' perception of radiological techniques about radiation protection in the work process in Nuclear Medicine. The research was carried out with nine professionals of the radiological techniques of two private institutions located in the South of Brazil. An interview was applied through recording and transcription. The analysis of the data took place through a thematic analysis. The professionals' perception of radiological techniques regarding the radiological protection in the work process is evidenced when professionals mention the basic rules of radiation protection: time, shielding and distance as attitudes used to minimize the exposure to ionizing radiation. However, it was verified the fragility in the knowledge about the norms and legislation of the radiological protection

    Radiation exposures experienced by workers are widely explained. The first evidences of biological effects, the implications for human health and the radiological protection have been covered. The conceptual structure that covers the radiological protection and adequate protection without limiting benefits, the scientific basis of radiology, the benefits and risks of the radiological protection are specified. The effective per capita doses are exposed in medical uses both for Latin America and for other regions in the average radiology, dental radiology, nuclear medicine and radiotherapy. The manners of occupational exposures in the medicine are presented. Industrial uses have also its average effective dose in the industrial irradiation, industrial radiography and radioisotopes production. Within the natural radiation the natural sources can significantly contribute to occupational exposure and have their average effective dose. Occupational medical surveillance to be taken into industrial sites is detailed. In addition, the plan of international action for the solution of dilemmas of occupational exposures is mentioned and the different dilemmas of radioactive exposure are showed. The external irradiation, the acute diseases by radiations, the cutaneous syndrome of the chronic radiation, the radioactive contamination, the internal radioactive contamination, the combined lesion and accidental exposures are also treated [es

    An important activity of the International Atomic Energy Agency is the promotion of training in radiological protection. Through its organized training courses, its fellowship training programme and its field experts, the Agency has assisted many Member States to train an essential group of scientists in radiological protection. Many Member States are now developing their own national training programmes in radiological protection and this report has been prepared to provide the guidance that may be required in this development. In the report the various types of training which are encountered in a radiological protection programme are fully discussed, curricula are suggested and examples of established training courses are annexed

    The overarching objective of the radiological protection system is to contribute to an appropriate level of protection against the harmful effects of radiation exposure, without unjustifiably limiting the desired results from the human activity causing exposure. Such a balance is achieved by understanding as best as possible the scientific characteristics of radiation exposure and the related health effects, and by taking this knowledge into consideration when judging which protection decisions will ensure the best balance between social and economic aspects and risks. In general, the existing radiological protection system, on which national regulations are built in virtually every country in the world, works well and does not underestimate protection needs for either individuals or exposed populations as a whole. The latest International Commission on Radiological Protection (ICRP) recommendations, which define this protection system, were formed after a long and open dialogue with the public, where expert views were actively collected and discussed at national, regional and international levels. Although the radiological protection system is very effective, and there is no current need for a prompt revision, it is important nonetheless to keep a watchful eye on the latest scientific results, and to work to ensure that the entire radiological protection community is kept up to date on evolving and emerging scientific issues. In this way, potential or actual scientific changes can be appropriately identified and in turn can stimulate reflection on changes that might be needed in the protection system, in policy, in regulation and in practice. Such reflection should benefit from the input of other scientific disciplines and interested stakeholders. To contribute to this process, the NEA Committee on Radiological Protection and Public Health (CRPPH) has periodically reviewed and released reports on the state of the art in radiological protection science (see NEA

    it is notorious that one of the main causes of radiological accidents is the lack of knowledge of radiological protection of workers. In order to meet the needs of professionals in acquiring a solid base in radiological protection and safety, was created in 2013, by the Casa Branca School / SP and technically supported by the company MAXIM Cursos, the 'Post-Graduation Course Lato Sensu de Radiological Protection in Medical, Industrial and Nuclear Applications', which offers a broad improvement in radiation protection. The course of 380 hours and duration of 18 months is divided into 13 modules, including theoretical classes, in person and online using the virtual classroom and practical training in radiation protection in general. In the end students should present a monograph, guided by a course teacher and reviewed by an Examining Bank. Five classes have been formed in these four years, totaling 92 students. In all, 51 monographs have been defended on topics of technical and scientific interest. For this, the Faculty consists of 25 professors, being 9 Doctors, 13 Masters and 3 Specialists in Radiological Protection

    The workshop provides a forum for exchange of information and experience among regulators, scientists and governmental and non-governmental organisations in the areas of radiological protection and public health. This is the second in the series of NEA workshops on this subject. The first Science and Values in Radiological Protection workshop was held in Helsinki in January 2008 and hosted by the Radiation and Nuclear Safety Authority of Finland (STUK). The workshop focussed on developing a shared understanding between various stakeholders and identifying the elements of a framework more suited to the integration of new scientific and technological developments and socio-political considerations in radiological protection. This second workshop focusses on radiological protection issues that are currently facing us, and that continue to pose challenges to our world today.

    The objective of Radiological Protection is to guarantee that neither people, be they workers or members of the public, or the environment are exposed to radiological risks considered by society to be unacceptable. Among the various resources available to meet this objective is Research and Development (R and D), which is carried out in three areas: I. Radiological protection of persons: (a) knowledge of the biological effects of radiations, in order to determine the relationship that exists between radiation exposure dose and its effects on health; (b) the development of new personal dosimetry techniques in order to adapt to new situations, instrumental techniques and information management technologies allowing for better assessment of exposure dose; and (c) development of the principle of radiological protection optimisation (ALARA), which has been set up internationally as the fundamental principle on which radiological protection interventions are based. II. Assessment of environmental radiological impact, the objective of which is to assess the nature and magnitude of situations of exposure to ionising radiations as a result of the controlled or uncontrolled release of radioactive material to the environment, and III.Reduction of the radiological impact of radioactive wastes, the objective of which is to develop radioactive material and waste management techniques suitable for each situation, in order to reduce the risks associated with their definitive management or their release to the environment. Briefly described below are the strategic lines of R and D of the CSN, the Electricity Industry, Ciemat and Enresa in the aforementioned areas. (Author)

    Due to the short term, long term and genetic effects of radiation, the work with radioactive materials requires special protection measures. The objective of radiological protection is to assure the occupational health of the workers by maintaining the dose levels as low as reasonably achievable. The radiological protection measures implanted in the NUCLEBRAS fuel element factory are described. The philosophy and practical measures taken are explained, and a comparison between radiation protection and industrial safety norms is made. The result of this work shows that the radiological safety of the element factory is assured. (author) [pt

    The Radiological Protection Plan - PPR, quoted by the Regulatory Standard 32, requires to be maintained at the workplace and at the disposal of the worker's inspection the PPR, for it to be aware of their work environment and the damage that can be caused by misuse of ionizing radiation. Objective: to discuss the interface between PPR and ethical reflection. Method: this is a reflective study. Discussion and results: regulatory norm 32 points out that the worker who conducts activities in areas where there are sources of ionizing radiation should know the risks associated with their work. However, it is considered that the sectors of hospital radiology the multidisciplinary health team is exposed to ionizing radiation and has not always aware of the harm caused by it, so end up unprotected conduct their activities. Concomitantly, recent studies emphasize the radiological protection and concern for the dangers of radiation on humans, but rather refer to the legislation about the radiological protection. In this context an ethical reflection is necessary, seeking to combine work ethics liability to care in protecting themselves and the other with the institutional conditions for this protection becomes effective

    By means of a research carried out in Radiotherapy Centers in Mexico City, divided in 7 public institutions and 5 private, aspects related to the radiological safety and its organization in radiotherapy were evaluated. The population being studied was: medical and technical personnel, that works in the selected radiotherapy centers. The survey was made with 36 dichotomic variables, being obtained 90 surveys. The personnel characteristics are: 76% works for more than 3 years in radiotherapy, 93% has updated information about radiological protection, 67% knows the general radiological safety regulations, 93% knows the radiological emergency project and 95% makes use of personal dosemeter. As result of this research we found that the main problems that the radiological protection have are: lack of personnel training in radiological protection, although the 93% states to have updated information, the few number of persons that takes part in clinical meetings and professional associations.

    Occupational exposures at nuclear power plants worldwide have steadily decreased since the early 1990's. Regulatory pressures, technological advances, improved plant designs and operational procedures, as low as reasonably achievable (ALARA) culture and information exchange have contributed to this downward trend. However, with the continued ageing and possible life extensions of nuclear power plants, ongoing economic pressures, regulatory, social and political evolutions, and the potential of new nuclear build, the task of ensuring that occupational exposures are kept as low as reasonably achievable continues to present challenges to radiological protection professionals

The X-rays and the radioactive materials used in medicine have allowed to realize important progresses and to develop new technologies skills for the diagnosis, the therapy and the prevention of diseases. Having in it counts tells the risks associated with the ionizing radiations, it is required legally that the personnel that intervenes in the different procedures has the necessary knowledge of radiological protection to assure that the use of radiations in the medical practice should carry out of ideal form, at the right moment and adopting all the necessary measures to guarantee the best protection, so much of the occupationally exposed personnel, since as, like of the patients and the public in general. The virtual environments for the construction of the knowledge like it is the virtual university, allows presenting an effective alternative in the learning of different areas and in this particular case of the radiological protection. With the aim lens to give response to these needs there is implemented this pilot virtual course year based on the current course of radiological protection that is dictated in the Mastery in Medical Physics of the National University of Colombia, sedate Bogota. The purpose of this virtual course is to use as academic and bibliographical support on radiological protection, as well as to answer to the needs of initial formation that the professionals have, to acquire a solid base in the mentioned matter. It has been conceived so that it provides theoretical formation, so much scientific as technology and that contemplates the recommendations and international and national procedure on radiological protection and some applications. Given the incorporation of the technologies of information and communication that in the academic area it has brought with it not only to give support to the curricular activities but

    This article summarizes the development of protection against ionizing radiation and explains current thinking in the field. It also looks at the decisive role that regulatory agencies for radiological protection must play and the important contributions that can be made by health authorities. The latter should take an active part in at least three aspects: the formal education of health personnel regarding radiological protection; the medical care of individuals who are accidentally overexposed, and the radiological protection of patients undergoing radiological procedures. To this end, health professionals must possess sufficient knowledge about radiological protection, promote the use of proper equipment, and apply the necessary quality assurance procedures. Through their effective intervention, national health authorities can greatly contribute to reducing unnecessary doses of radiation during medical procedures involving radiation sources and decrease the chances that radiological accidents will take place.

    International Commission on Radiological Protection (ICRP), an independent international organization established in 1925, develops, maintains, and elaborates radiological protection standards, legislation, and guidelines. United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) provides scientific evidence. World Health Organization (WHO) and International Atomic Energy Agency (IAEA) utilise the ICRP recommendations to implement radiation protection in practice. Finally, radiation protection agencies in each country adopt the policies, and adapt them to each situation. In Korea, Nuclear Safety and Security Commission is the governmental body for nuclear safety regulation and Korea Institute of Nuclear Safety is a public organization for technical support and R&D in nuclear safety and radiation protection.

    This study aims to assess the adequacy level of radiological protection systems available in the diagnostic radiology facilities located in three capital cities of North East (NE) India. It further attempts to understand, using a multi-disciplinary approach, how the safety codes/standards in diagnostic radiology framed by the Atomic Energy Regulatory Board (AERB) and the International Atomic Energy Agency (IAEA) to achieve adequate radiological protection in facilities, have been perceived, conceptualized, and applied accordingly in these facilities. About 30 diagnostic radiology facilities were randomly selected from three capitals of states in NE India; namely Imphal (Manipur), Shillong (Meghalaya) and Guwahati (Assam). A semi-structured questionnaire developed based on a multi-disciplinary approach was used for this study. It was observed that radiological practices undertaken in these facilities were not exactly in line with safety codes/standards in diagnostic radiology of the AERB and the IAEA. About 50% of the facilities had registered/licensed x-ray equipment with the AERB. More than 80% of the workers did not use radiation protective devices, although these devices were available in the facilities. About 85% of facilities had no institutional risk management system. About 70% of the facilities did not carry out periodic quality assurance testing of their x-ray equipment or surveys of radiation leakage around the x-ray room, and did not display radiation safety indicators in the x-ray rooms. Workers in these facilities exhibited low risk perception about the risks associated with these practices. The majority of diagnostic radiology facilities in NE India did not comply with the radiological safety codes/standards framed by the AERB and IAEA. The study found inadequate levels of radiological protection systems in the majority of facilities. This study suggests a need to establish firm measures that comply with the radiological safety codes/standards of the

    The Commission on Radiological Protection was asked to give advice on the practical implications of the absorption of the maximum possible activity values that, under the Radiological Protection Ordinance, may be incorporated in women of child-bearing age occupationally exposed to radiation with regard to incorporation monitoring and compliance with the dose limit for the protection of the unborn child. An unborn child's conceivable level of exposure to radiation in the least favourable case due to continuous and single incorporations of radionuclides in the mother was determined on a nuclide-specific basis by the Federal Office for Radiation Protection with the aid of the mathematical metabolic models provided in ICRP 88. At the proposal of the Commission on Radiological Protection, the Federal Office for Radiation Protection considered the following very conservative scenarios: - the mother's maximum possible exposure due to a continuous intake of activity over 10 years prior to the pregnancy and in the first 10 weeks postconception based on the limits set out in the Radiological Protection Ordinance; - the mother's maximum possible exposure due to a single intake at the most unfavourable time in the first 10 weeks postconception based on the limits set out in the Radiological Protection Ordinance. Examination of these scenarios found that, with a few exceptions, the dose to the unborn child attributable to the incorporation of radiation in the mother summed up over 70 years is less than that to the mother. The committed effective dose to the unborn child from certain radionuclides may exceed the value of 1 mSv when the dose to the mother reaches the maximum limit. The Commission on Radiological Protection was therefore asked 1. to examine whether compliance with the limit of 1 mSv effective dose is sufficient for the protection of the unborn child or whether any additional limitation is required for individual organs, 2. to discuss the implications for

    Paediatric patients have a higher average risk of developing cancer compared with adults receiving the same dose. The longer life expectancy in children allows more time for any harmful effects of radiation to manifest, and developing organs and tissues are more sensitive to the effects of radiation. This publication aims to provide guiding principles of radiological protection for referring clinicians and clinical staff performing diagnostic imaging and interventional procedures for paediatric patients. It begins with a brief description of the basic concepts of radiological protection, followed by the general aspects of radiological protection, including principles of justification and optimisation. Guidelines and suggestions for radiological protection in specific modalities – radiography and fluoroscopy, interventional radiology, and computed tomography – are subsequently covered in depth. The report concludes with a summary and recommendations. The importance of rigorous justification of radiological procedures is emphasised for every procedure involving ionising radiation, and the use of imaging modalities that are non-ionising should always be considered. The basic aim of optimisation of radiological protection is to adjust imaging parameters and institute protective measures such that the required image is obtained with the lowest possible dose of radiation, and that net benefit is maximised to maintain sufficient quality for diagnostic interpretation. Special consideration should be given to the availability of dose reduction measures when purchasing new imaging equipment for paediatric use. One of the unique aspects of paediatric imaging is with regards to the wide range in patient size (and weight), therefore requiring special attention to optimisation and modification of equipment, technique, and imaging parameters. Examples of good radiographic and fluoroscopic technique include attention to patient positioning, field size and adequate collimation

    The International School for Radiological Protection, a task force within SCK-CEN, co-ordinates and organises training programs on all aspects of radiological protection. IsRP courses are directed as well to the private sector as to the political and academic world and the general public. International meetings, publications and recommendations with regard to safety culture increasingly stress the importance of education and training in the field of radiological protection. In addition, the need to standardise and harmonise the recognition of skills and practices on a national and European level is emerging. In this sense, the objectives of isRP are threefold : (1) to continue the organisation of open courses and training-on-demand of which the programmes are made up according to the background level and training requirements of the participants, and this for the Belgian medical and industrial sector; (2) to come to a closer cooperation with national universities and high schools and relevant international institutions; (3) to contribute to a better harmonisation of training practice and of skills recognition on a national and European level

    The application of ionizing radiation in medicine seems to be a safe procedure for patients as well as for occupational exposition to personnel. The developments in interventional radiology with fluoroscopy and dose-intensive interventions require intensified radiation protection. It is recommended that all available tools should be used for this purpose. Besides the options for instruments, x‑ray protection at the intervention table must be intensively practiced with lead aprons and mounted lead glass. A special focus on eye protection to prevent cataracts is also recommended. The development of cataracts might no longer be deterministic, as confirmed by new data; therefore, the International Commission on Radiological Protection (ICRP) has lowered the threshold dose value for eyes from 150 mSv/year to 20 mSv/year. Measurements show that the new values can be achieved by applying all X‑ray protection measures plus lead-containing eyeglasses.

    Committee 3 of the International Commission on Radiological Protection (ICRP) is concerned with protection in medicine, and develops recommendations and guidance on the protection of patients, staff, and the public against radiation exposure in medicine. This paper presents an overview of the work of Committee 3 over recent years, and the work in progress agreed at the last annual meeting in Bethesda, MD in October 2011. The reports published by ICRP dealing with radiological protection in medicine in the last 10 years cover topics on: education and training in radiological protection; preventing accidental exposures in radiation therapy; dose to patients from radiopharmaceuticals; radiation safety aspects of brachytherapy; release of patients after therapy with unsealed radionuclides; managing patient dose in digital radiology and computed tomography; avoidance of radiation injuries from medical interventional procedures; pregnancy and medical radiation; and diagnostic reference levels in medical imaging. Three new reports will be published in the coming months dealing with aspects of radiological protection in fluoroscopically guided procedures outside imaging departments; cardiology; and paediatric radiology. The work in progress agreed by Committee 3 is also described.

    The purpose of the International Society of Radiology (ISR), as being the global organization of radiologists, is to promote and help co-ordinate the progress of radiology throughout the world. In this capacity and as a co-operating organization of the IAEA, the ISR has a specific responsibility in the global radiological protection of patients. Globally, there are many users of medical radiation, and radiology may be practised in the most awkward circumstances. The individuals performing X ray studies as well as those interpreting them may be well trained, as in industrialized parts of the world, but also less knowledgeable, as in developing areas. The problems of radiological protection, both of patients and of radiation workers, still exist, and radiation equipment is largely diffused throughout the world. That is why a conference like this is today as important as ever. Radiation protection is achieved through education, on the one hand, and legislation, on the other. Legislation and regulation are the instruments of national authorities. The means of the ISR are education and information. Good radiological practice is something that can be taught. The ISR is doing this mainly through the biannual International Congress of Radiology (ICR), now arranged in an area of radiological need; the three previous ICRs were in China, in India and in South America; the next one is going to be in Mexico in 2002. The goal of the ICR is mainly to be an instructive and educational event, especially designed for the needs of its surrounding region. The ISR is aiming at producing educational material. The International Commission on Radiological Education (ICRE), as part of the ISR, is launching the production of a series of educational booklets, which also include radiation protection. The ICRE is actively involved in shaping and organizing the educational and scientific programme of the ICRs

    2007-01-01

    On 21 March 1957, the Steering Committee for Nuclear Energy of the Organisation for European Economic Co-operation established the Working Party on Public Health and Safety. From this early date onwards, radiological protection formed a central part of the work of what was to become the OECD Nuclear Energy Agency. Now, 50 years later, the Committee on Radiation Protection and Public Health (CRPPH) has commissioned this historical review of half a century of work and accomplishments. Over this period, the key topics in radiological protection have been identified, debated and addressed by the CRPPH. This report brings this history to life, presenting the major questions in the context of their time, and of the personalities who worked to address them. The developments and views of the past condition how we are able to assess and manage radiological risks today, as well as how we may adjust to challenges that will or could emerge in the coming years. This heritage is thus an important element for the CRPPH to consider as it looks forward to its next 50 years of accomplishments. (author)

  17. Radiation Protection in Paediatric Radiology

    International Nuclear Information System (INIS)

    2012-01-01

    Over the past decade and a half, special issues have arisen regarding the protection of children undergoing radiological examinations. These issues have come to the consciousness of a gradually widening group of concerned professionals and the public, largely because of the natural instinct to protect children from unnecessary harm. Some tissues in children are more sensitive to radiation and children have a long life expectancy, during which significant pathology can emerge. The instinct to protect children has received further impetus from the level of professional and public concern articulated in the wake of media responses to certain publications in the professional literature. Many institutions have highlighted the need to pay particular attention to the special problems of protecting paediatric patients. The International Commission on Radiological Protection has noted it and the IAEA's General Safety Requirements publication, Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (BSS), requires it. This need has been endorsed implicitly in the advisory material on paediatric computed tomography scanning issued by bodies such as the US Food and Drug Administration and the National Cancer Institute in the United States of America, as well as by many initiatives taken by other national and regional radiological societies and professional bodies. A major part of patient exposure, in general, and paediatric exposure, in particular, now arises from practices that barely existed two decades ago. For practitioners and regulators, it is evident that this innovation has been driven both by the imaging industry and by an ever increasing array of new applications generated and validated in the clinical environment. Regulation, industrial standardization, safety procedures and advice on best practice lag (inevitably) behind industrial and clinical innovations. This Safety Report is designed to consolidate and provide timely advice on

    In the Peru, according to the current regulations, people that work with ionizing radiations should have an authorization (individual license), which is granted by the Technical Office of the National Authority that is the technical body of the Instituto Peruano de Energia Nuclear (IPEN) manager of the control of ionizing radiations in the country. The individual license is obtained after the applicant fulfills the requested requirements, as having safety knowledge and radiological protection. Since its founding in 1972, the Centro Superior de Estudios Nucleares (CSEN) of the IPEN has carried out diverse training courses in order to that people can work in a safe way with ionizing radiations in medicine, industry and research, until the year 2013 have been organized 2231 courses that have allowed the training of 26213 people. The courses are organized according to the specific work that is carried out with radiations (medical radio-diagnostic, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear meters, logging while drilling, etc.). In their majority the courses are directed to people that will make use of radiations for first time, but refresher courses are also granted in the topic. The CSEN also carries out the Master degree programs highlighting the Second Professional Specialization in Radiological Protection carried out from the year 2004 with the support of the National University of Engineering. To the present has been carried out 2 programs and there is other being developed. In this work is shown the historical evolution of the radiological protection courses as well as the important thing that they are to work in a safe way in the country. (Author)

    In recent publications, such as Publications 117 and 120, the Commission provided practical advice for physicians and other healthcare personnel on measures to protect their patients and themselves during interventional procedures. These measures can only be effective if they are encompassed by a framework of radiological protection elements, and by the availability of professionals with responsibilities in radiological protection. This framework includes a radiological protection programme with a strategy for exposure monitoring, protective garments, education and training, and quality assurance of the programme implementation. Professionals with responsibilities in occupational radiological protection for interventional procedures include: medical physicists; radiological protection specialists; personnel working in dosimetry services; clinical applications support personnel from the suppliers and maintenance companies; staff engaged in training, standardisation of equipment, and procedures; staff responsible for occupational health; hospital administrators responsible for providing financial support; and professional bodies and regulators. This publication addresses these elements and these audiences, and provides advice on specific issues, such as assessment of effective dose from dosimeter readings when an apron is worn, estimation of exposure of the lens of the eye (with and without protective eyewear), extremity monitoring, selection and testing of protective garments, and auditing the interventional procedures when occupational doses are unusually high or low (the latter meaning that the dosimeter may not have been worn).

    The hood is recognized throughout the nuclear industry as the standard radiological protective head covering for use in radioactively contaminated work environments. As of June 15, 1995, hoods were required for all activities performed in contaminated areas at the Y-12 Plant. The use of hoods had historically been limited to those radiological activities with a high potential for personnel contamination. Due to the large size of many posted contaminated areas at the Y-12 Plant, and compounding safety factors, requirements for the use of hoods are being reevaluated. The purpose of the evaluation is to develop technically sound guidelines for the selection of hoods when prescribing radiological protective head covering. This report presents the guidelines for selection of radiological protective hoods

    Two years after the massive release of radiation from the nuclear power plants at Fukushima Dai-ichi, the repercussions continue to preoccupy the radiological and emergency protection community, both in Switzerland and internationally. In Switzerland the Swiss Federal Nuclear Safety Inspectorate (ENSI) has initiated measures as part of the European Union Stress Tests and has its own Fukushima Action Plan. In this Annual Report, ENSI focuses on radiological protection in Swiss nuclear facilities. The average individual dose has changed little compared with previous years. At 0.7 mSv, it is significantly below the limit both for persons exposed to radiation during their work (20 mSv) and the annual average rate of exposure for the population in Switzerland as a whole (5.5 mSv). In terms of collective doses, the extensive maintenance work at the Leibstadt power plant (KKL) resulted in a doubling of rates compared with recent years. However, in the remaining nuclear facilities the rates have not changed significantly. The highest individual dose during the year under review was 13 mSv. Exposure rates in 2012 for all those exposed to radiation during work in facilities subject to ENSI surveillance were below the maximum limit. Greater attention is now being given to work in high and variable radiation fields and in difficult conditions. Swiss nuclear facilities continue to operate a consistent radiological protection approach. Measuring equipment plays an important role in radiological protection. Having conducted a range of inspections and comparative measurements of aerosol-iodine filters and waste water sampling together with measurements in the field of personal dosimetry, ENSI has concluded that the required measuring equipment for radiological protection exists, that this equipment is correctly used and provides reliable data. ENSI maintains a test laboratory that analyses samples from nuclear facilities and their immediate vicinity and also conducts field

    Many trends and indicators suggest that the use of nuclear power for generating electricity will increase, perhaps significantly, in the coming 10 to 20 years and beyond. Any such expansion will not take place in a static scientific or social context, but rather in the midst of ongoing changes in many relevant fields, radiological protection, radioactive waste management and nuclear safety to name a few. Regarding radiological protection, this evolution can be characterised in many different ways, but can conveniently be described as having scientific and socially driven aspects. These may well pose challenges to radiological protection (RP) policy, regulation and application in the future

    2013-01-01

    ICRP has provided an updated overview of radiation protection principles in pediatric radiology. The authors recommend that staff, radiologists, medical physicists and vendors involved in pediatric radiology read this document. For conventional radiography, the report gives advice on patient positioning, immobilization, shielding and appropriate exposure conditions. It describes extensively the use of pulsed fluoroscopy, the importance of limiting fluoroscopy time, and how shielding and geometry must be used to avoid unnecessary radiation to the patient and operator. Furthermore, the use of fluoroscopy in interventional procedures with emphasis on dose reduction to patients and staff is discussed in light of the increasing frequency, complexity and length ofthe procedures. CT is the main reason that medical imaging in several developed countries is the highest annual per capita effective radiation dose from man-made sources. The ICRP report gives extensive descriptions of how CT protocols can be optimized to minimize radiation exposure in pediatric patients. The importance of balancing image quality with acceptable noise in pediatric imaging and the controversies regarding the use of protective shielding in CT are also discussed.

    In the present study we describes the evaluation of the effectiveness of gonad protection in diagnostic radiology based on the measurement of organ and the effective doses with and without lead clothing to gonads. We devised in-phantom dosimetry system and measured organ and effective doses in x-ray radiography and CT examinations with the new dosimetry system. From the data of organ and the effective doses we assessed the effectiveness of radiological protection by the use of lead clothing to gonads. Although in chest radiography and chest CT examinations, the effectiveness of radiological protection was not found, in the case of hip joint radiography (AP), gonad doses decreased remarkably by using lead clothing. The effectiveness of radiological protection, i.e. the ratio of the decreased dose to the dose value without protection, in testis and ovary were found to be 91.4% and 68.0%, respectively. It was also found that gonad doses observed with and without gonad protection were extremely lower than those of threshold for sterility recommended by the International Commission on Radiological Protection 60 (ICRP Publ. 60).

    Energy Technology Data Exchange (ETDEWEB)

    Holliday, B

    1974-01-01

    Information that would allow an assessment of the standard of radiological protection in dentistry in the United Kingdom is sparse. The National Radiological Protection Board (previously the Radiological Protection Service) has provided a monitoring and advisory service to dentists for many years but very limited use has been made of this service. In a recent survey, 114 dentists were visited in representative practices in South East England and it was established that only 6.5% of dentists in general practice do not use radiography as an adjunct to their practice (Smith, 1969). In the 88 x-ray sets which were examined, 24% had less than the recommended thickness of aluminium filtration, while 25% had a fixed field size which was larger than necessary for dental radiography; in addition, 27% of the timers were found to have an error of greater than 20% in repetition of the pre-set exposure time. The exposure rate at the cone tip of a dental x-ray unit is generally in the range 1 to 4 R/s. A fault in the timer unit coupled with a failure on the part of the dentist to notice that x-rays are being generated (normally indicated by a red warning light) would rapidly lead to excessive exposure of the patient. Furthermore, a dentist continually holding films in the mouth of his patient would certainly incur a dose well in excess of the permissible hand dose, assuming anaverage work load for the x-ray equipment. Three case histories are given to illustrate the type of hazard that might arise from faulty equipment or bad operating technique.

    Radiological protection began with particle accelerators. Many of the concerns in the health physics profession today were discovered at accelerator laboratories. Since the mid-1940s, our understanding has progressed through seven stages: observation of high radiation levels; shielding; development of dosimetric techniques; studies of induced activity and environmental impact; legislative and regulatory concerns; and disposal. The technical and scientific aspects of accelerator radiation safety are well in hand. In the US, there is an urgent need to move away from a ''best available technology'' philosophy to risk-based health protection standards. The newer accelerators will present interesting radiological protection issues, including copious muon production and high LET (neutron) environments

    2005-01-01

    Since 1992, the Nuclear Energy Agency (NEA), along with the International Atomic Energy Agency (IAEA), has sponsored the Information System on Occupational Exposure (ISOE). ISOE collects and analyses occupational exposure data and experience from over 400 nuclear power plants around the world and is a forum for radiological protection experts from both nuclear power plants and regulatory authorities to share lessons learned and best practices in the management of worker radiation exposures. In connection to the ongoing work of the International Commission on Radiological Protection (ICRP) to develop new recommendations, the ISOE programme has been interested in how the new recommendations would affect operational radiological protection application at nuclear power plants. Bearing in mind that the ICRP is developing, in addition to new general recommendations, a new recommendation specifically on optimisation, the ISOE programme created a working group to study the operational aspects of optimisation, and to identify the key factors in optimisation that could usefully be reflected in ICRP recommendations. In addition, the Group identified areas where further ICRP clarification and guidance would be of assistance to practitioners, both at the plant and the regulatory authority. The specific objective of this ISOE work was to provide operational radiological protection input, based on practical experience, to the development of new ICRP recommendations, particularly in the area of optimisation. This will help assure that new recommendations will best serve the needs of those implementing radiation protection standards, for the public and for workers, at both national and international levels.

    Program in radiological equipment has incorporated more powerful x-ray sources into the standard Fluoroscopy and CT systems. Expanding use of interventional procedures carries extensive use of fluoroscopy and CT which are both associated with excessive radiation exposure to the patient and personnel. During cases of Intravenous CT Angiography and direct Intraarterial CT Angiography, one may substitute a substantial number of diagnostic angiography checks. Basic training in interventional radiology hardly includes some of the fundamentals of radiation protection. Radiation Protection in Interventional Radiology must be implemented in daily practice and become an integral part of procedure planning strategy in each and every case. Interventional radiological most master all modern imaging modalities in order to choose the most effective, but least hazardous one. In addition, one must be able to use various imaging techniques (Fluoroscopy, CTA, MM and US) as a stand-alone method, as well as combine two techniques or more. Training programs for fellows: K-based simulation of procedures and radiation protection. Special attention should be taken in the training institutions and a basic training in radiation protection is advised before the trainee is involved in the practical work. Amendment of techniques for balloon and stent deployment with minimal use of fluoroscopy. Attention to the differences between radiation protection in cardiovascular and nonvascular radiology with special measures that must be taken for each one of them (i.e., peripheral angiography vs. stenting, Endo luminal Aortic Stent Graft, or nonvascular procedures such as biliary or endo urological stenting or biliary intervention). A special emphasis should be put on the training techniques of Interventional Radiologists, both beginners and experienced. Patient dose monitoring by maintaining records of fluoroscopic time is better with non-reset timer, but is optional. Lee of automated systems that

    The use more and more frequent of radiations in different areas of the daily life generate a growing necessity of competent professionals and technicians qualified in Health Physics. The teaching of the Radiological Protection does not limit only to the instruction in scientists topics that quality to the professionals in the resolution of problems or the application of techniques, must qualified also the students in the diffusion of the own problems of the radiological protection. The content of different courses of radiological protection given in the Instituto Bailer's ( a join between the National University of Cuyo and the National Commission of Atomic Energy) guided to different groups of students or professionals are also introduced. Finally, some of the examples used in order to clarify practical situations are shown. (author)

  10. Radiological protection of the environment: the path forward to a new policy?

    International Nuclear Information System (INIS)

    2002-01-01

    The international system of radiological protection is currently being revised with the aim of making it more coherent and concise. During the revision process, particular attention is being given to the development of an explicit system for the radiological protection of the environment in addition to that of human beings. In order to support the ongoing discussions of the international community of radiological protection experts, these proceedings try to answer the questions: Is there an international rationale behind the wish to protect the environment from radiation? Do we have enough scientific information to develop and define a broadly accepted policy? What are the socio-political dynamics, beyond science, that will influence policy on radiological protection of the environment? What are the characteristics of the process for developing a system of radiological protection of the environment? These proceedings comprise the views of a broad range of invited speakers, including policy makers, regulators, radiological protection and environmental protection professionals, industry, social scientists and representatives of both non-governmental and intergovernmental organisations.

  11. Ethical values in radiological protection

    1996-01-01

    Issues like consent, equity, control and responsibility are important for an ethical evaluation of radiation risks. This paper discusses the incorporation of ethical values in radiological protection policy and compares how ICRP recommendations promote their use in practice and intervention cases. The paper contends that in cases of intervention, where the overall aim is dose reduction, social and ethical factors are often alluded to when evaluating costs of an action. However, possible ethical or social benefits of intervention measures are seldom raised. On the other hand, when assessing a practice, wherein the net effect is an increase in radiation dose, one is more likely to find an appeal to ethical factors on the benefits side of the equation than with the costs. The paper concludes that all decisions concerning radiological protection should consider both positive and negative ethical aspects. (author)

    The program of operative radiological protection of a nuclear power plant consists of multiple procedures and associate tasks that have as purpose the radiological protection of the workers of the power station. It is for this reason that the constant evaluation of the one it programs it is an important tool in the identification of their weaknesses (and strengths), so they can be assisted appropriately. In this work the main elements of the program of independent auto evaluation of the program of operative radiological protection of the Laguna Verde Central that has been developed and implemented by the National Institute of Nuclear Research are described.

    The ALARA principle as a requirement in radiological protection has evolved from its theoretical roots. Based on several years work, this paper provides a backdrop to practical approaches to ALARA for the 1990s. The key step, developing ALARA thinking so that it becomes an integral part of radiological protection programmes, is discussed using examples from the UK and France, as is the role of tools to help standardise judgements for decision-making. In its latest recommendations, ICRP have suggested that the optimisation of protection should be constrained by restrictions on the doses to individuals. This paper also considers the function of such restrictions for occupational, public and medical exposure, and in the design process. (author)

    Despite a longstanding recognition that radiological protection is not only a matter of science, but also ethics, ICRP publications have rarely addressed the ethical foundations of the system of radiological protection explicitly. The purpose of this publication is to describe how the Commission has relied on ethical values, either intentionally or indirectly, in developing the system of radiological protection with the objective of presenting a coherent view of how ethics is part of this system. In so doing, it helps to clarify the inherent value judgements made in achieving the aim of the radiological protection system as underlined by the Commission in Publication 103. Although primarily addressed to the radiological protection community, this publication is also intended to address authorities, operators, workers, medical professionals, patients, the public, and its representatives (e.g. NGOs) acting in the interest of the protection of people and the environment. This publication provides the key steps concerning the scientific, ethical, and practical evolutions of the system of radiological protection since the first ICRP publication in 1928. It then describes the four core ethical values underpinning the present system: beneficence/ non-maleficence, prudence, justice, and dignity. It also discusses how these core ethical values relate to the principles of radiological protection, namely justification, optimisation, and limitation. The publication finally addresses key procedural values that are required for the practical implementation of the system, focusing on accountability, transparency, and inclusiveness. The Commission sees this publication as a founding document to be elaborated further in different situations and circumstances.

  16. Principles of radiological protection: new paradigms

    Full text: The relationships of workers, patients and physicians to the basic principles of radiological protection were given in this work an historical introduction that emphasizes their development from their beginnings to the current period. The evolution of scientific knowledge as regards the benefits and injuries resulting from the use of the ionizing radiation in human activities is the main focus of the work. These principles (justification, optimization and limitation) are presented in order to offer a broader view of their application fields. The principle of the optimization receives the contribution of techniques aimed to help the decision used in radiological protection. The principle of the limitation of doses is helped by the concept of limit specifically linked to a given segment of the population or a given human activity. Regarding the current relationship between physicians and patients a change of philosophy is discussed in what concerns the radiation dose supplied that should be the minimum one in relation to the diagnosis or cure objectives. The administration of radiation must follow the recommendations of ICRP - International Commission on Radiological Protection. The radiation can bring benefits if used with rationality, efficacy and care. The radiation should not be feared, but respected. (author)

  17. Evolution of the radiological protection paradigms

    We consider as initial radiological protection paradigms those in vigour after the release of the atomic energy for pacific usages in 1955. In that occasion, only one paradigm was introduced, presently named dose limitation system. After arguing about the basis that raised the paradigm, we introduced the guidance, that is, the measurements to be implemented to comply with the paradigm. In that occasion, they were two, i.e., the radiation dose monitoring and the workplace classification. Afterwards, the reasons that caused the radiological protection paradigms changes in force until 1995 are discussed. The initial paradigm was modified introducing the justification and the optimization principles, adding that the radiological protection should be economical and effective. The guidance also increased to four: personal monitoring, workplace classification, reference level and workers classification. Afterwards, we give the main justifications for the present paradigms that besides the formers were added the dose constraints, the potential exposure and the annual risk limits. Due to these modifications, the workers classifications were eliminated from the guidance, but the potential exposure and the search for the dose constraints were added. Eventually, we discuss the tendencies for the next future and the main changes introduced by the ICRP in the Publication 103, 2007. (author)

  18. Action research regarding the optimisation of radiological protection for nurses during vascular interventional radiology

    The optimisation and decision-making processes for radiological protection have been broadened by the introduction of re-examination or feedback after introducing protective measures. In this study, action research was used to reduce the occupational exposure of vascular interventional radiology (IR) nurses. Four radiological protection improvement measures were continuously performed in cooperation with the researchers, nurses and stakeholders, and the nurses’ annual effective doses were compared before and after the improvements. First, the dosimetry equipment was changed from one electronic personal dosimeter (EPD) to two silver-activated phosphate glass dosimeters (PGDs). Second, the nurses were educated regarding maintaining a safe distance from the sources of scattered and leakage radiation. Third, portable radiation shielding screens were placed in the IR rooms. Fourth, the x-ray units’ pulse rates were reduced by half. On changing the dosimetry method, the two PGDs recorded a 4.4 fold greater dose than the single EPD. Educating nurses regarding radiological protection and reducing the pulse rates by half decreased their effective doses to one-third and two-fifths of the baseline dose, respectively. No significant difference in their doses was detected after the placement of the shielding screens. Therefore, the action research effectively decreased the occupational doses of the vascular IR nurses. (practical matter)

    Aspects related to radiological safety and its organization in radiodiagnosis were evaluated by means of scanning carried out in 18 hospitals of Mexico City, divided in 11 public institutions and 7 private ones. The population being studied was: hospital personnel that works in radiodiagnosis. The survey was made with 31 dichotomic variables, being obtained 132 surveys. The personnel characteristics are 83% works in public institutions, 49% works in radiodiagnosis, 3% has an academic degree, 13% is member of a hospital professional association, 13% has updated information on radiological protection, 36% was trained, 45% works for more than 2 years, 52% uses personal dosemeter, less than the 20% knows about the fundamentals of the radiological protection and 24% states to suffer from biological radiation effects, due to the exposure to x-rays. As result of the study, it was found that the main problems that the radiological protection has, are: lack of training programs in radiological protection and supervision, medical surveillance and the few number of persons that takes part in clinical meetings and professional associations.

    In 1999, the International Radiological Protection Association (IRPA) asked for contributions to the debate on future changes to the radiological protection system proposed by the International Commission on Radiological Protection (ICRP). In response, the Board of the French Society for Radiation Protection (SFRP) created a working group to deal specifically with this issue. It met on several occasions between April and July and its findings were presented at the IRPA Congress in May 2000. They were also published in the French journal Radioprotection and in the British Journal of Radiological Protection. To further its discussions, the Board of the SFRP decided to create a second working group which became operational in September 2001. It has around 20 members representing the major players in the radiological protection field in France: authorities, experts and professionals from the nuclear, medical and research fields as well as one association representative (the list of members can be found at the end of this document). The working group was set up to produce proposals relating to the key issues likely to be raised, particularly by the ICRP, concerning the development of new radiological protection recommendations. The members of the working group analysed the ICRP memorandum published in the June 2001 edition of the Journal of Radiological Protection and used their own experience to determine what these key issues would be. The following issues were discussed: General thoughts on the new radiological protection system proposed by the ICRP, Individual and collective approaches to the radiological risk, Comparison with chemical risk management, Radiological protection of the environment, Changes in exposure levels and units of measurement. This paper, which has been approved by the Board of the SFRP, gives the main conclusions of the working group on the key issues in these areas. It is intended to reflect the various opinions expressed during the groups

    2017-06-01

    In the radiological protection report 2016, the Swiss Federal Nuclear Safety Inspectorate (ENSI) provides an overview of the radiological protection in its area of supervision. Part A of the report deals with protecting the staff of nuclear power plants from the dangers of ionising radiation. It also includes a list of the personal doses accumulated by the staff, broken down using various parameters. Applying the optimisation imperative, it has been proved possible to significantly reduce the annual collective doses in Switzerland's nuclear power plants since they came on stream thanks to major efforts by the operators. In 2016, a total of 6,153 people measured accumulated 2,877 person-mSv. The collective doses have reached a low level corresponding to the radiological condition of the plants and the scope of the work required to be performed in controlled zones (e.g. non-destructive materials testing). ENSI will continue to follow the trend for collective doses and assess the reasons for local variances as well as for measures initiated. The individual doses for people employed in ENSI's area of supervision in 2016 showed a maximum figure of 10 mSv and a mean value of 0.5 mSv which was significantly below the dose limit of 20 mSv for occupational radiation exposure. The discharge of radioactive substances with the exhaust air and waste water from nuclear power plants are dealt with in Part B of the report. In 2016, nuclear power plant operators again met the admissible release limits set by the authorities, in some cases by a considerable margin. The emissions of Swiss nuclear power plants led to a dose of less than 0.01 mSv per year in the direct neighbourhood. A comparison with the average annual radiation dose for the Swiss population of 5.5 mSv shows that the relevant contribution from nuclear power plants lies in the area of one percent of this figure. Effluents from Swiss nuclear power plants were also below the target of 1 GBq per year set by ENSI

  10. Evaluation of the conditions and practices of radiological protection technicians in radiology, according to Ordinance 453

    Professionals in radiology suffer whole body exposure to low doses for long periods . The system of radiological protection should keep exposures below recommended thresholds, thus avoiding the stochastic effects that can be triggered with any dose level value, and there is not a threshold for induction of the same. Therefore it is important to use personal dosimeter for monitoring doses and protective equipment. The increase in procedures using ionizing radiation in recent years has been noted with concern, since many companies are not complying with the standards of protection. This is because some procedures may be performed without the need of surgery, which presents a greater risk to the patient. Furthermore, Brazilians are being exposed to radiation without necessity. The reasons range from radiological equipment miscalibrated to poorly trained staff. Thus we evaluate the conditions and practices of radiation protection technicians in radiology according to Ordinance 453 in Goiania, GO, Brazil. Through a descriptive survey with a quantitative approach, we used the technique of gathering information based on a questionnaire. From this survey, we identified the procedures used by radiation protection professionals and concluded that there are failures in the procedures for protecting patients and accompanying and in the training of the professionals.

    The mandate of Committee 3 of the International Commission on Radiological Protection (ICRP) is concerned with the protection of persons and unborn children when ionising radiation is used in medical diagnosis, therapy, and biomedical research. Protection in veterinary medicine has been newly added to the mandate. Committee 3 develops recommendations and guidance in these areas. The most recent documents published by ICRP that relate to radiological protection in medicine are 'Radiological protection in cone beam computed tomography' (ICRP Publication 129) and 'Radiological protection in ion beam radiotherapy' (ICRP Publication 127). A report in cooperation with ICRP Committee 2 entitled 'Radiation dose to patients from radiopharmaceuticals: a compendium of current information related to frequently used substances' (ICRP Publication 128) has also been published. 'Diagnostic reference levels in medical imaging' (ICRP Publication 135), published in 2017, provides specific advice on the setting and use of diagnostic reference levels for diagnostic and interventional radiology, digital imaging, computed tomography, nuclear medicine, paediatrics, and multi-modality procedures. 'Occupational radiological protection in interventional procedures' was published in March 2018 as ICRP Publication 139. A document on radiological protection in therapy with radiopharmaceuticals is likely to be published in 2018. Work is in progress on several other topics, including appropriate use of effective dose in collaboration with the other ICRP committees, guidance for occupational radiological protection in brachytherapy, justification in medical imaging, and radiation doses to patients from radiopharmaceuticals (an update to ICRP Publication 128). Committee 3 is also considering the development of guidance on radiological protection in medicine related to individual radiosusceptibility, in collaboration with ICRP Committee 1.

    The most important sources of ionizing radiation for general public are medical sources. Good working protocols and radiological protections measurements provided significant reduction of patients and professional doses. Medical users of ionizing radiation are radiological technologists. The purpose of this paper is to point out to several facts and errors in radiation protection educational programs for radiological technologists. Medical College educational program covers main specific topics in radiation protection, but there are some omissions in training process. Radiological technologists must be actively involved in radiation protection. Following ethical standards they will reach higher standards than the law requires

The Inspectorate concludes that radiological protection in Swiss nuclear facilities is carried out consistently and in compliance with existing legislation.

  17. A new approach to authorization in the field of radiological protection

    International Nuclear Information System (INIS)

    2003-01-01

    Approaches to radiological protection have been evolving, particularly over the past several years. This has been driven by the emergence of modern concepts of and approaches to risk governance, and by calls from within the radiological protection community for the simplification and clarification of the existing system of protection, as based on the Recommendations of the International Commission on Radiological Protection (ICRP). The NEA Committee on Radiation Protection and Public Health (CRPPH) has been very active in developing its own suggestions as to how the system of radiological protection should evolve to better meet the needs of policy makers, regulators and practitioners. One of those suggestions is that a generic concept of 'regulatory authorization' of certain levels and types of exposure to radiation should replace the current and somewhat complicated concepts of exclusion, exemption and clearance. It has also been suggested that by characterising emerging sources and exposures in a screening process leading into the authorization process, regulatory authorities could develop a better feeling for the type and scale of stakeholder involvement that would be necessary to reach a widely accepted approach to radiological protection. In order to verify that these suggestions would make the system of radiological protection more understandable, easy to apply, and acceptable, independent consultants have 'road tested' the CRPPH concepts of authorization and characterisation. Their findings, which show that applying these concepts would represent significant improvement, are reproduced herein. Specific approaches for the application of the new CRPPH ideas are also illustrated in this report. (author)

    A high-level radioactive waste, generated at a nuclear fuel reprocessing plant, will be disposed of deep, i.e., several hundred meters, within geological formations, to isolate it from the human environment. Since the waste contains significant amounts of long-lived radionuclides, such as Tc-99, I-129, Cs-135 and transuranic elements, the safety of its disposal, particularly as regards the requirement for the radiological protection of human and his environment even in the far future, is one of the essential subjects of all countries engaged in nuclear power production. The radiological protection system has long been established and applied to regulate radiation exposures to the public associated with a relatively short-term release of radioactive materials, during normal and accidental conditions, from nuclear installations such as a power plant and reprocessing plant. Radioactive waste disposal, which potentially offers a long-term radiological consequence on the public, inevitably produces a specific requirement, from the standpoint of radiological protection, that individuals and populations in the future should be accorded at least a current level of the protection. This requirement has caused a serious debate, among the community of radiological protection, on how to establish radiological protection standards and criteria, and how to establish safety assessment methodologies to demonstrate compliance with them. We have discussed in this paper on specific items such as numerical guides to indicate radiological consequences, time frames over which calculations of the consequences are to be carried out, uncertainties to be involved in the calculations, and safety assessment methodologies.

    The regulation antecedents in nuclear question in Mexico are placed in 1950, with the promulgation of L aw that declares national mining reserves the uranium deposits, thorium and the other substances of which obtains fissionable isotopes that can produce nuclear energy , instrument that stipulated the control of uranium, thorium, as to its it indicated it name, and other fissionable substances, on the part of the state, although they were without a doubt the respective institutions, the National Commission of Nuclear Energy in 1955, and the one of the National Commission of Nuclear Safety and Safeguards (CNSNS) in 1979, those that allowed the development of a prescribed frame in the nuclear and radiological areas. One characteristic of the regulation in radiological protection is the variety in the authorities type that have incidence in the regulation, as a result of the different approaches with which it can be approached. For example, in Mexico normative instruments with content in radiological protection exist and are watched over the Health Secretary, who is oriented to the protection of the patient, their relatives and the medical body; Work and Social Welfare Secretary, with a labor approach; Communications and Transport Secretary, which regulates the transport of nuclear and radioactive materials; Finance and Public Credit Secretary, who regulates the import and export of radioactive materials; Environment and Natural Resources Secretary, which regulates the environment protection; Energy Secretary who has responsibilities inside of the p rescribed law of article 27 constitutional in nuclear matter ; and within the energy sector, the CNSNS that expedite and watch the fulfillment of normative in radiological protection and nuclear safety. In order to resist effects of on regulation; frequently inter institutional agreements are carried out in which the areas of monitoring are agreed by each authority. The regulation in radiological protection demands the

    For several years a reference center of the UCV has been working on the project VEN/9/007 on dose reduction in diagnostic radiology sponsored by the IAEA. The dose and quality image was evaluated for different types of radiological study (conventional radiology, CT, mammography, interventional radiology) in different facilities at Caracas and others regions of the Venezuela. TL dosimeters were used to assess dose and reduction in dose. Based on the recommendations given by CEC documents on diagnostic quality criteria, a quality control program in radiological protection of patients and staff has been developed, for example: Pilot study by using TLD in personnel radiation monitoring. Comparative study between high and low kVp in chest. Evaluation and dose reduction in chest pediatric. Reduction of radiation dose in studies of billiards via Quality Image and reduction of the dose in studies of colon by enema. Radiation dose of staff in fluoroscopy procedures. Evaluation and dose reduction in dental radiography in public Institutions. A mammography accreditation program for Venezuela, applied to public hospitals. (author)

    Several potential problems have been detected in the safety aspects for the practice of interventional radiology procedures: a) An important increase in the number cases and their complexity and the corresponding increase of installations and specialists involved; b) New X ray systems more sophisticated, with advanced operational possibilities, requiring special skills in the operators to obtain the expected benefits;c) New medical specialists arriving to the interventional arena to profit the benefits of the interventional techniques without previous experience in radiation protection. For that reason, education and training is one of the basic areas in any optimisation programme in radiation protection (RP). the medical field and especially interventional radiology requires actions to promote and to profit the benefit of the new emerging technologies for training (Internet, electronic books, etc). The EC has recently sponsored the MARTIR programme (Multimedia and Audio-visual Radiation Protection Training in Interventional Radiology) with the production of two videos on basic aspects of RP and quality control and one interactive CD-ROM to allow tailored individual training programmes. those educational tools are being distributed cost free in the main European languages.

    The International Commission on Radiological Protection (ICRP) has sustained interest in radiological protection in computed tomography (CT), and ICRP Publications 87 and 102 focused on the management of patient doses in CT and multi-detector CT (MDCT) respectively. ICRP forecasted and 'sounded the alarm' on increasing patient doses in CT, and recommended actions for manufacturers and users. One of the approaches was that safety is best achieved when it is built into the machine, rather than left as a matter of choice for users. In view of upcoming challenges posed by newer systems that use cone beam geometry for CT (CBCT), and their widened usage, often by untrained users, a new ICRP task group has been working on radiological protection issues in CBCT. Some of the issues identified by the task group are: lack of standardisation of dosimetry in CBCT; the false belief within the medical and dental community that CBCT is a 'light', low-dose CT whereas mobile CBCT units and newer applications, particularly C-arm CT in interventional procedures, involve higher doses; lack of training in radiological protection among clinical users; and lack of dose information and tracking in many applications. This paper provides a summary of approaches used in CT and MDCT, and preliminary information regarding work just published for radiological protection in CBCT. © The International Society for Prosthetics and Orthotics Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    The results obtained by the Cuban Center for Radiological Protection and Hygiene by using an analytical tree technique to develop its general operational radiation protection program are presented. By the application of this method, some factors such as the organization of the radiation protection services, the provision of administrative requirements, the existing general laboratories requirements, the viability of resources and the current documentation was evaluated. Main components were considered such as: complete normative and regulatory documentation; automatic radiological protection data management; scope of 'on the-job'and radiological protection training for the personnel; previous radiological appraisal for the safety performance of the works and application of dose constrains for the personnel and the public. The detailed development of the program allowed to identify the basic aims to be achieved in its maintenance and improvement. (authors). 3 refs

    Non-governmental environmental organisations (environmental NGOs) may consider the issue of radiological protection of the environment differently to other interested parties such as regulators or industry. While environmental NGOs are broadly positive towards the current emphasis and engagement on radiological protection of the environment per se, there remain concerns about the precise meaning of the term and the ultimate objectives of the current initiatives. Various strategies are studied and discussed. The disposal of radioactive waste at sea is discussed and a case study presented. What the environmental NGOs are looking for is focused upon and various environmental protection systems are discussed (tk)

    In its 11{sup th} Annual Report on Radiological Protection, the Swiss Federal Nuclear Safety Inspectorate (ENSI) provides the public with information on dose rates for individuals professionally exposed to radiation, releases of radioactive material and the monitoring of environmental radiation. ENSI, as the regulatory body for nuclear facilities in Switzerland, is continuing to expand its information provision over and above that contained in the Radiological Protection Report. At 0.6 mSv per year, the average individual dose for professionally exposed persons remains significantly below the annual limit of 20 mSv specified by the Swiss Federal Council. It is also less than the average annual rate of natural environmental exposure of 5.5 mSv for the population in Switzerland as a whole. The highest individual dose during the year was 12 mSv. The collective doses lie within the range of past years. There is a trend towards higher collective doses at KKL. As a general rule, planning by the licensees of nuclear facilities in the field of radiological protection is of a high standard. Actual collective doses in 2014 at Beznau 1, Goesgen and Leibstadt were within 10% of projected exposure rates and at Beznau 2 and Muehleberg the doses were about 30% lower. Demands in terms of radiological protection were particularly high at Leibstadt and Beznau 1; at Leibstadt mainly as a result of a fuel cladding defect and at Beznau 1 because of the continuing elevated ambient rate for components in the primary circuit. ENSI concluded that the Swiss nuclear facilities continue to operate a consistent approach to radiological protection. In 2014, licensees of nuclear facilities remained within official release limits, in some cases by a significant margin. Liquid releases from Muehleberg were below the target value of 1 GBq per year set by ENSI on the basis of international recommendations.

    Radiological protection criteria for waste disposal options are currently being developed at the National Radiological Protection Board (NRPB), and, in parallel, methodologies to be used in assessing the radiological impact of these options are being evolved. The criteria and methodologies under development are intended to apply to all solid radioactive wastes, including the high-level waste arising from reprocessing of spent nuclear fuel (because this waste will be solidified prior to disposal) and gaseous or liquid wastes which have been converted to solid form. It is envisaged that the same criteria will be applied to all solid waste disposal options, including shallow land burial, emplacement on the ocean bed (sea dumping), geological disposal on land and sub-seabed disposal

    Two years after the massive release of radiation from the nuclear power plants at Fukushima Dai-ichi, the repercussions continue to preoccupy the radiological and emergency protection community, both in Switzerland and internationally. In Switzerland the Swiss Federal Nuclear Safety Inspectorate (ENSI) has initiated measures as part of the European Union Stress Tests and has its own Fukushima Action Plan. In this Annual Report, ENSI focuses on radiological protection in Swiss nuclear facilities. The average individual dose has changed little compared with previous years. At 0.7 mSv, it is significantly below the limit both for persons exposed to radiation during their work (20 mSv) and the annual average rate of exposure for the population in Switzerland as a whole (5.5 mSv). In terms of collective doses, the extensive maintenance work at the Leibstadt power plant (KKL) resulted in a doubling of rates compared with recent years. However, in the remaining nuclear facilities the rates have not changed significantly. The highest individual dose during the year under review was 13 mSv. Exposure rates in 2012 for all those exposed to radiation during work in facilities subject to ENSI surveillance were below the maximum limit. Greater attention is now being given to work in high and variable radiation fields and in difficult conditions. Swiss nuclear facilities continue to operate a consistent radiological protection approach. Measuring equipment plays an important role in radiological protection. Having conducted a range of inspections and comparative measurements of aerosol-iodine filters and waste water sampling together with measurements in the field of personal dosimetry, ENSI has concluded that the required measuring equipment for radiological protection exists, that this equipment is correctly used and provides reliable data. ENSI maintains a test laboratory that analyses samples from nuclear facilities and their immediate vicinity and also conducts field

    The UK Nuclear Industry is in the midst of a period of intense change with the formation of a national body to manage the clean up of Nuclear facilities. Previous owners of nuclear sites have become contractors and the emphasis has switched from production facilities for power or reprocessing to decommissioning and clean up. Many of the older facilities were not designed for decommissioning and now require attention to reduce risks. Sellafield represents a microcosm of the industry with operating and production facilities, waste storage facilities and plants awaiting or undergoing decommissioning. The experience already gained in decommissioning of redundant facilities over the last decade is being used to develop an accelerated response to clean up of the past. The major challenge is to accommodate the changes whilst monitoring and improving Radiological standards and performance. This paper describes a number of issues to which the site must be managed to ensure that the current Radiological performance is maintained and improved. The dose control arrangements for some 6000 radiation workers on the site requires a change in approach as we move towards localised project based systems with an increasingly mobile workforce. Work is proceeding to introduce a new generation of short term dose control equipment with an emphasis on safety culture and management responsibilities for dose control. The achievement and demonstration of ALARP in these circumstances, is being reviewed in situations where timescale, overall risk to public and workforce and exposure to non radiological hazards are factors. Clean up requires more attention to clearance of materials and this aspect has an increasing profile to recognize the need to balance risk and expenditure. The paper will review the current Radiological Protection challenges to the changing Nuclear Industry using the Sellafield site as the prime example and will discuss achievements and areas where further work is necessary

    The optimization concept in radiation protection is, in its essence, practical. In each aspect that we deal with the man, it is necessary to take frequent decisions such as: what is the protection level to be pursued, since the protection levels under consideration provide doses lower than the appropriate annual limits. The optimization gives a basic framework of the minding that is appropriate to conduct to a balance kind of the resources available for the protection and protection level obtained against a multitude of factors and constrains in a manner to obtain the best result. In this work, was performed the optimization, from the radiation protection point of view, of a facility project who enclose two shielded hot cells where will be handled UO 2 small plate with 50% of U-235 burn-up, irradiated in the research swimming pool reactor, IEA-R1. To obtain this goal were specified the relevant factors and criteria, were applied the main techniques used in a decision-making in radiological protection, presently adopted and was performed a sensibility study of the factors and criteria used in this work. In order to obtain a greater agility in applying the techniques for decision-making was developed a micro computer program. (author)

    The development of a common European radiation protection and safety culture and, based on that, the mutual recognition of radiation protection courses and the acquired competencies of radiation protection experts (RPE) and officers (RPO) is becoming a real need. The ENETRAP project ('European Network for Education and Training in RAdiological Protection') aims at bringing together different ideas and approaches of education and training (E and T) in radiological protection (RP) in order to better integrate and harmonise national E and T activities on a European level. The project started in April 2005. 10 partners are involved in ENETRAP: SCK-CEN (coordinator), CEA-INSTN, FZK-FTU, BfS, ENEA, NRG, CIEMAT, HPA-RPD, UJF and UHI-NHC. These partners have years of experience with established E and T programmes and play an important role in the development of specific techniques such as e-learning or On-the-Job Training (OJT) related to RP. As a result of their fundamental scientific research, collaboration with industry and practical experience, the partners have a solid scientific knowledge of all aspects of RP and are ideally placed to transfer the know-how and estimate the needs in this field. The ENETRAP project aims at establishing a sustainable E and T infrastructure for RP as an essential component to combat the perceived decline in expertise and to ensure the continuation of the high level of RP knowledge. The main objectives of the ENETRAP project are (1) to better integrate existing E and T activities in the RP infrastructure of the European countries in order to combat the decline in both student numbers and teaching institutions, (2) to develop more harmonised approaches for E and T in RP in Europe, (3) to better integrate the national resources and capacities for E and T and (4) to provide the necessary competence and expertise for the continued safe use of radiation in industry, medicine and research. Any such infrastructure must ensure that provision is

    Full text: This paper summarizes the scope of activities, ongoing experience and current results of the Expert Group on the Public Health Perspective in Radiological Protection (EGPH) of the Committee of Radiological Protection and Public Health, OECD Nuclear Energy Agency. While the prime and general task of the EGPH group is looking at how the public health and radiation protection can better take an advantage of their respective perspectives, the following four areas have been explored in detail: a) Exposure to radon; b) Justification of medical exposures; c) Public health judgement and decision making based on new scientific evidence; and d) Management of individual differences. In most of these areas, a targeted telephone survey on public policies in selected countries was used for collecting information from stake holders (public, consumers groups, public health and radiation protection regulators, governmental bodies, medical practitioners, patients, scientific communities, NGOs, etc.). The presented paper also highlights key issues of collected information and summarises existing approaches and policies. The case study on exposure to radon collects national information on approaches to the management of domestic radon risks, focusing on the integration of radiation protection and public health aspects (quality of dwellings, overall quality of indoor air, perception of radon levels, position of radon risk in the pool of other risks). In the case of justification of medical exposures, the Group studies the applications of the justification principle in opportunistic screenings (responsibilities, management of the situation, risk assessment). The precautionary principle and its impact on policy judgement in the light of significant scientific uncertainties can have a large influence on radiological-protection decision making. The case study on public health judgement and decision making based on new scientific evidence is exploring how these uncertainties and

    International Nuclear Information System (INIS)

    2013-12-01

    The System of radiological protection develops gradually integrating advances in knowledge about the effects of radiation, the feedback from its practical implementation in all relevant domains, as well as the evolution of the ethical and social values that shape community life in modern societies. Although there is a long tradition of ICRP to consider such values in the development of its Recommendations, there is a need to make them explicit. This should facilitate the understanding of the system for specialists and non-specialists in radiological protection and allow a renewed dialogue on its foundations, its objectives and rationality. It should also encourage the emergence of informed behaviours in society vis-a-vis radiations. In this perspective, ICRP has initiated a reflection in the recent years on the ethical dimensions of the radiological protection system. This reflection has highlighted the links between the fundamental principles of radiation protection (justification, optimization, limitation) and the theories of normative ethics. The recommendations of the Commission are designed to respect individual rights (deontological ethics), to promote the collective interest (utilitarian ethics) and favour vigilance and equity (virtue ethics). This reflection it also identified the interest for the analysis of the radiological protection system to distinguish the ethical values defining the standards by which action should be taken, the ethical procedures for integrating these values in decision making and in the implementation of the decisions, and the ethical behaviour corresponding to the values that are supposed to guide the conduct of the various actors. Because the radiation protection system is intended to be international, the reflection also emphasized the importance of promoting through the Recommendations, values common to different cultures such as autonomy, non-maleficence, beneficence and justice. The objective of the Workshop is to explore

    To propose measures for radiological protection of veterinary workers in Japan, X-ray exposure of workers in typical conditions in veterinary clinics was assessed. Dose rates of useful beam and scattered radiation, worker exposure doses at different stations, and effectiveness of protective clothing were determined using TLD and ion chambers. As precausions against radiation, the following practices are important: (1) use of suitable and properly maintained X-ray equipment, (2) proper selection of safe working stations, (3) use of protective clothing. Regulations are necessary to restrict the use of X-rays in the veterinary field. Because the use of X-rays in the veterinary field is not currently controlled by law, the above precautions are essential for minimizing exposure of veterinary staff. (author)

  9. Work management to optimise occupational radiological protection

    2009-01-01

    Although work management is no longer a new concept, continued efforts are still needed to ensure that good performance, outcomes and trends are maintained in the face of current and future challenges. The ISOE programme thus created an Expert Group on Work Management in 2007 to develop an updated report reflecting the current state of knowledge, technology and experience in the occupational radiological protection of workers at nuclear power plants. Published in 2009, the new ISOE report on Work Management to Optimise Occupational Radiological Protection in the Nuclear Power Industry provides up-to-date practical guidance on the application of work management principles. Work management measures aim at optimising occupational radiological protection in the context of the economic viability of the installation. Important factors in this respect are measures and techniques influencing i) dose and dose rate, including source- term reduction; ii) exposure, including amount of time spent in controlled areas for operations; and iii) efficiency in short- and long-term planning, worker involvement, coordination and training. Equally important due to their broad, cross-cutting nature are the motivational and organisational arrangements adopted. The responsibility for these aspects may reside in various parts of an installation's organisational structure, and thus, a multi-disciplinary approach must be recognised, accounted for and well-integrated in any work. Based on the operational experience within the ISOE programme, the following key areas of work management have been identified: - regulatory aspects; - ALARA management policy; - worker involvement and performance; - work planning and scheduling; - work preparation; - work implementation; - work assessment and feedback; - ensuring continuous improvement. The details of each of these areas are elaborated and illustrated in the report through examples and case studies arising from ISOE experience. They are intended to

  10. Protecting people against radiation exposure in the event of a radiological attack

    This report responds to a widely perceived need for professional advice on radiological protection measures to be undertaken in the event of a radiological attack. The report, which is mainly concerned with possible attacks involving 'radioactive dispersion devices', re-affirms the applicability of existing ICRP recommendations to such situations, should they ever occur. Many aspects of the emergency scenarios expected to arise in the event of a radiological attack may be similar to those that experience has shown can arise from radiological accidents, but there may also be important differences. For instance, a radiological attack would probably be targeted at a public area, possibly in an urban environment, where the presence of radiation is not anticipated and the dispersion conditions commonly assumed for a nuclear or radiological emergency, such as at a nuclear installation, may not be applicable. First responders to a radiological attack and other rescuers need to be adequately trained and to have the proper equipment for identifying radiation and radioactive contamination, and specialists in radiological protection must be available to provide advice. It may be prudent to assume that radiological, chemical, and/or biological agents are involved in an attack until it is proven otherwise. This calls for an 'all-hazard' approach to the response. In the aftermath of an attack, the main aim of radiological protection must be to prevent the occurrence of acute health effects attributable to radiation exposure (termed 'deterministic' effects) and to restrict the likelihood of late health effects (termed 'stochastic' effects) such as cancers and some hereditable diseases. A supplementary aim is to minimise environmental contamination from radioactive residues and the subsequent general disruption of daily life. The report notes that action taken to avert exposures is a much more effective protective measure than protective measure the provision of medical treatment

  11. Scientific issues and emerging challenges for radiological protection

    International Nuclear Information System (INIS)

    2007-01-01

    Scientific knowledge is constantly evolving as more advanced technologies become available and more in-depth research is carried out. Given the potential implications that new findings could have on policy decisions, in 1998 the NEA Committee on Radiation Protection and Public Health (CRPPH) performed a survey of state-of-the-art research in radiological protection science. This study suggested that, while the current system of radiological protection was well under-pinned by scientific understanding, growing knowledge in several areas could seriously impact policy and regulation. Ten years later, the CRPPH has again performed a survey of state-of-the-art research which reiterates and clarifies its earlier conclusions. This report summarises the results of this latest CRPPH assessment of radiological protection science. Specifically, it explains that knowledge of non-targeted and delayed effects, as well as of individual sensitivity, have been significantly refined over the past ten years. Although at this point there is still no scientific certainty in these areas, based on the most recent studies and results, the report strongly suggests that policy makers and regulatory authorities should consider possible impacts that could arise from research in the next few years. Further, the report identifies research areas that should be supported to more definitively answer scientific questions having the most direct impacts on policy choices. (author)

  12. Proceedings of the 4. International Conference on Education and Training in Radiological Protection - ETRAP 2009 Transactions

    International Nuclear Information System (INIS)

    2009-01-01

    Education and training are the two basic pillars of any policy regarding safety in the workplace. Practitioners who work with radiation sources will have a wide range of responsibilities and objectives depending on the radiation practice, but all will have a triple common need: a basic education as well as specific training providing the required level of understanding of artificial and natural radiation and its management; standards for the recognition of skills and experience; an opportunity to refresh, update and test acquired knowledge and competence on a regular basis. International meetings, publications and recommendations covering safety culture in the field of radiological protection increasingly stress the need for education and training. In addition, compliance with the requirements of specific European directives and the international basic safety standards is crucial in a world of dynamic markets and increasing workers mobility, and common approaches to training facilitate the understanding of these requirements. The conference intends to address the largest potential audience, covering policy makers, the medical sector, industrial radiographers, NORM experts, the engineering sector, the non-nuclear industry, social sciences researchers, safety experts, radiation protection experts, radiation protection officers, medical physics experts, regulators and authorities. Furthermore, it aims to reinforce the contacts between various organisations, individuals and networks dealing with education and training policies in radiological protection. Special attention will also be paid to attracting and inviting young professionals to ensure knowledge transfer and to help build the future of radiological protection. (authors)

    It is widely accepted that Radiological Protection has a real social dimension and it is not restricted to the pure scientific and quantitative aspects. The quality in radiation protection is not reached by simply complying with current technical standards or by enforcing an improved or restricted regulation, but must also be pursued by promoting a culture of radiation protection. An effective dissemination of a radiation protection culture has to include education and training for those students who will become researchers in the involved fields, or who will be called in risk management and, as protection managers, will be asked to inform and train workers or to communicate with the public. Today, in most universities the education in ethics is a significant part of the training in medical, biological and biotechnological curricula but, it is still of poor consideration in those curricula which are traditionally related to Physical Science and even in those areas, like Health Physics, where implementation of interdisciplinary approaches and methodologies are important sources for progress. Moreover, recent advances in the research field of risk perception and communication are very rarely included in those courses. At the Health Physics post-graduate School of Milano State University, within the course of Radiation Protection, a new subject has been recently introduced facing the question of ethical problems and risk perception in radiation protection, and dealing with the activity of international organisations aimed to establish ethical principles for protection against ionising radiation. By referring to this context, students realize how the analysis of radiological risk includes both technological and ethical aspects. The hope is that a new generation of experts in heath physics will promote a dynamic development of knowledge and a higher degree of awareness even in ethical aspects within the academic, institutional or professional fields of radiation

    Valetin, J.

    2011-01-01

    This report was prepared to underpin the Commission's 2007 Recommendations with regard to the medical exposure of patients, including their comforters and carers, and volunteers in biomedical research. It addresses the proper application of the fundamental principles (justification, optimisation of protection, and application of dose limits) of the Commission's 2007 Recommendations to these individuals. With regard to medical exposure of patients, it is not appropriate to apply dose limits or dose constraints, because such limits would often do more harm than good. Often, there are concurrent chronic, severe, or even life-threatening medical conditions that are more critical than the radiation exposure. The emphasis is then on justification of the medical procedures and on the optimisation of radiological protection. In diagnostic and interventional procedures, justification of procedures (for a defined purpose and for an individual patient), and management of the patient dose commensurate with the medical task, are the appropriate mechanisms to avoid unnecessary or unproductive radiation exposure. Equipment features that facilitate patient dose management, and diagnostic reference levels derived at the appropriate national, regional, or local level, are likely to be the most effective approaches. In radiation therapy, the avoidance of accidents is a predominant issue. With regard to comforters and carers, and volunteers in biomedical research, dose constraints are appropriate. Over the last decade, the Commission has published a number of documents that provided detailed advice related to radiological protection and safety in the medical applications of ionising radiation. Each of the publications addressed a specific topic defined by the type of radiation source and the medical discipline in which the source is applied, and was written with the intent of communicating directly with the relevant medical practitioners and supporting medical staff.

    The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

    1981-01-01

    Courses in Radiological Protection have been organised at Leeds by the NRPB since its formation, and prior to that by the Leeds Centre of the Radiological Protection Service. From the outset it seemed essential that such courses should contain a practical element, and accordingly a number of exercises were drawn up. Since that time further exercises have been added, often in response to a specific requirement from a customer or group of customers. Most of the exercises have involved the design and construction of 'one-off' items of equipment, a number of which can be considered to represent interesting approaches towards radiological protection teaching. The construction of a 'second generation' of hardware has focused attention on the objectives and design features of the exercises, which in turn has prompted a desire to publish a series of short papers describing the pool of exercises that is currently available for inclusion in the various courses run by the NRPB Centres. The first of these papers puts the series into context and provides a background to the descriptions of specific exercises. (author)

    1997-01-01

    In 1995, a European initiative for optimizing radiation protection in interventional radiology was proposed by 8 research groups. The project acronym was STPAPIR (Staff Radiation Protection in Interventional Radiology). Interventional Radiology involves an important number of specialists and their risk level is not well known, since dosimetric records exhibit important discrepancies. Many professionals using these techniques are not radiologists and the basic rules of radiation protection, known by radiologists, are not always correctly and completely followed, hence the use of protection devices is not as regular as desirable. Additionally, x-ray systems not specifically designed for interventional procedures are still used in many hospitals, what entails a significant occupational risk increase to the specialists. Some relevant questions for regulatory bodies are presented, namely, reliability of the actual data banks for occupational dosimetry, use of two personal dosimeters for assessing effective dose, actions to strengthen the systematic use of personal dosimeters and protection tools, proposals for specific training in radiation protection and use of x-ray systems specifically designed for interventional procedures, publication of reports about accidents and incidents, are also discussed.

    Ionizing radiations are used in areas such as health, industry and safety, not only in the private sector, but also in the public. Thus, it is necessary the radiological protection, a set of studies and practices that increases the safety in these applications, where the professional involved is the technologist in radiology. The objective was to analyze the contents effectively required by the Brazilian public agencies in their competitions for radiology technologist, regarding the area of radiological protection, identifying their profile of requirement. It consisted of three stages: first, a survey of all the public competitions already carried out in the country up to the end of 2016, that requested a diploma of graduation in Technology in Radiology; second, all the specific questions were collected and grouped in an electronic text file; third, issues involving radiological protection were segregated, using as reference the 2017 edition of the National Nuclear Energy Commission's General Proof of Radioprotection Supervision. The results showed that almost 40% of the competition questions were about radiation protection. From this sampling, the topics most covered were: radiological safety (36%), fundamentals of atomic and nuclear physics (24%) and biological effects of radiation (16%). It is concluded that the competitions for radiologist technologist have the profile of concentration of exigency in radiological safety, fundamentals of atomic and nuclear physics and biological effects of the radiations

    Ortiz M, J. R.

    2008-12-01

    The beginning in the use of the ionizing radiations goes back towards end of 19 century, when Wilhelm Roentgen discovers x-rays in 1985, finding that quickly founds also the new technology, which spreads to tabs of multiple applications anywhere in the world, some of very beneficial them of use like the radio diagnosis, but others of frivolous and commercial kind. As much in the beneficial uses as in the banal ones, the world also is begun to be aware that the ionizing radiations are a physical element that must be handled with precaution then also can induce injuries in the involved people, which is documented already in 1912. This characteristic is confirmed with the use of Radio-226 as source of ionizing radiation, in whose applications were observed some deleterious effects, which forces to take some measures of protection an intuitive and rather incipient way. The first attempt of limit was denominated erythema dose, that it was a concept of qualitative-subjective character when it is observed a reddening of the skin of the radiated zone. Just a short time later, with the invention of the detector Geiger and the possibility of measuring the radiation quantity received by the people, the limits are transformed into quantitative. lt is as well as it is born the radiological protection like scientific and technological discipline, and essential ally of the nuclear energy pacific applications , event in which the international organizations related to the subject play a very important role, in the middle of the 1920 decade. Since then radiological protection (RP) is in permanent evolution, keeping a balance between the people protection, the sources security and the benefits of the ionizing radiations applications. In Mexico, the nuclear energy taking height from the second half of 1950, when the National Commission of Nuclear Energy was created, it spent in his first years to functions that mainly were of investigation, but in which already appeared the RP like

    The National Radiological Protection Board (NPRB) is responsible in the UK for advising Government and other responsible bodies on the principles for responding to radiological emergencies. NRPB has published appropriate advice on the off-site protection of the public and on the protection of workers involved in taking mitigating actions to reduce the exposure of others. This paper puts forward a suggested framework for the protection of on-site personnel in the event of a radiological emergency which might include a criticality accident. This framework both dovetails with existing planning for the protection of members of the public off-site, and also takes account of specific differences between the situations on and off-site.

    1965-01-01

    This publication is a code of practice for the provision or radiological protection services for establishments in which, or in part of which, work is primarily with radiation sources. It was prepared with the help of an international panel of experts and representatives of international organizations which have an interest in this field and was promulgated by the Director General of the Agency under the authority of the Board of Governors of the Agency as a code of practice in the framework of the Agency's Safety Standards. The Board of Governors also authorized the Director General to recommend to Member States that the code of practice be taken into account in the formulation of national regulations or recommendations. The Appendix to the code contains a number of examples of the organization of radiological protection services that have been provided by the members of the panel of experts. These examples do not form a part of the code of practice, but are intended to illustrate the methods of organization which have been adopted in different countries.

  9. Implications of tissue reactions for radiological protection

    International Nuclear Information System (INIS)

    Miyazaki, S.

    2013-01-01

    Cancer effects and risks at low doses from ionising radiation have been main issues within the field of radiological protection. In contrast, non-cancer effects and risks at low doses from ionising radiation are controversial topics within the field of radiation protection. These issues are discussed in ICRP Publication 118, 'ICRP Statement on Tissue Reactions.' Both non-cancer effects and risks are expected to become increasingly important to the system of radiation protection. Before this can happen, several factors must be considered: thorough characterization of the relationship between dose and risk; verification of the biological mechanisms for any noted excess risk; and adjustment of noted excess risks through the use of a detriment factor. It is difficult to differentiate the relatively small risks associated with radiation from other risk factors in the low-dose region of the dose response curve. Several recent papers also indicate the possibility of a non-linear dose response relationship for non-cancer effects. In addition, there are still many uncertainties associated with the biological mechanisms for non-cancer effects. Finally, it is essential to consider the incorporation of detriment into a well-defined system of radiological protection. Given the recent interest in non-cancer effects, it is essential to facilitate discussions in order to more clearly define dose limits within the existing system of radiation protection for both cancer and non-cancer effects.

  12. Guidelines for training and qualification of radiological protection technicians

    International Nuclear Information System (INIS)

    1987-08-01

    These guidelines, used in combination with plant-specific job analysis, provide the framework for a training and qualification program for radiological protection technicians at nuclear power plants. Radiological protection technicians are defined as those individuals, both plant and contractor, who will be engaged in the evaluation of radiological conditions in the nuclear plant and the implementation of the necessary radiological safety measures as they apply to nuclear plant workers and members of the general public. An important aspect of this work is recognizing and handling unusual situations involving radioactivity, including incidents related to degraded core conditions. These guidelines incorporate the results of an industry-wide job analysis and task analysis (JTA) combined with industry operating experience review. However, the industry-wide analyses did not identify all important academic and fundamental knowledge and skills. Further in-depth analysis by subject matter experts produced additional knowledge and skills that were added to these guidelines. All utilities should use these guidelines in conjunction with plant-specific and industry-wide JTA results to develop or validate their radiological protection technician training program. Plant-specific information should be used to establish appropriate training program content. This plant-specific information should reflect unique job duties, equipment, operating experience, and trainee entry-level qualifications. Revisions to these guidelines should be reviewed for applicability and incorporated into the training program using each utility's training system development (TSD) procedures. Plant-specific job analysis and task analysis data is essential to the development of performance-based training programs. These analyses are particularly useful in selecting tasks for training and in developing on-the-job training (OJT), laboratory training, and mock-up training. Qualification programs based on these

    In the event of nuclear accident or radiological emergency, the protective action based on intervention levels prepared in advance should be implemented in order to minimize the public hazard. There are several protective measures such as sheltering, evacuation, iodine prophylaxis, foodstuff restrictions, temporary relocation, permanent resettlement, etc. for protecting the public. The protective measures should be implemented on the basis of operational intervention level of action level. This report describes the basic principles of intervention and the methodology for deriving intervention levels, and also recommendations for the intervention levels suggested from IAEA, ICRP, WHO and EU are summarized to apply to the domestic radiological emergency. This report also contains a revision procedure of operational intervention levels to meet a difference accident condition. Therefore, it can be usefully applied to establish revised operational intervention levels considering or the regional characteristics of our country. (author). 20 refs

    The objective of Radiological Protection is to gurantee that neither people, be they workers or members of the public, or the environment are exposed to radiological risks considered by society to be unacceptable. Among the various resources available to meet this objective is Research and Development (R and D), which is carried out in three areas: I. Radiological protection of persons: (a) knowledge of the biological effects of radiations, in order to determine the relationship that exists between radiation exposure dose and its effects on health; (b) the development of new personal dosimetry techniques in order to adapt to new situations, instrumental techniques and information managmenet technologies allowing for better assessment of exposure dose; and (c) development of the principle of radiological protection optimisation (ALARA), which has been set up internationally as the fundamental principle on which radiological protection interventions are based. II. Assessment of environmental radiological impact, the objective of which is to assess the nature and magnitude of situations of exposure to ionising radiations as a result of the controlled or uncontrolled release of radioactive material to the environment, and III.Reduction of the radiological impact of radioactive wastes, the objective of which is to develop radioactive material and waste management techniques suitable for each situation, in order to reduce the risks assocaited with their definitive managmenet or thier release to the environment. Briefly desribed below are the strategic lines of R and D of the CSN, the Electricity Industry, Ciemat and Enresa in the aforementioned areas. (Author)

    2004-01-01

    The primary aim of radiological protection has always been to provide an appropriate standard of protection for the public and workers without unduly limiting the beneficial practices giving rise to radiation exposure. Over the past few decades, many studies concerning the effects of ionising radiation have been conducted, ranging from those that examine the effects of radiation on individual cells, to epidemiological studies that examine the effects on large populations exposed to different radiation sources. Using information gained from these studies to estimate the consequences of radiation exposure, together with the necessary social and economic judgements, the International Commission on Radiological Protection (ICRP) has put forward a series of recommendations to structure an appropriate system for radiological protection, and to ensure a high standard of protection for the public and for occupational exposed workers. The ICRP system of radiological protection that has evolved over the years now covers many diverse radiological protection issues. Emerging issues have been dealt with more or less on an individual basis resulting in an overall system, which while very comprehensive, is also complex. With such a complex system it is not surprising that some perceived inconsistencies or incoherence may lead to concerns that radiation protection issues are not being adequately addressed. Different stakeholders in decisions involving radiological protection aspects tend to focus on different elements of this perceived incoherence. To advance solutions to these issues, the OECD Nuclear Energy Agency (NEA) has been working for some time to contribute to the evolution of a new radiological protection system, through its Committee on Radiation Protection and Public Health (CRPPH). This group of senior regulators and expert practitioners has, throughout its existence, been interested in the development of recommendations by the ICRP. Recently, this interest has

    In the Peru, according to the current regulations, people that work with ionizing radiations should have an authorization (individual license), which is granted by the Technical Office of the National Authority that is the technical body of the Instituto Peruano de Energia Nuclear (IPEN) manager of the control of ionizing radiations in the country. The individual license is obtained after the applicant fulfills the requested requirements, as having safety knowledge and radiological protection. Since its founding in 1972, the Centro Superior de Estudios Nucleares (CSEN) of the IPEN has carried out diverse training courses in order to that people can work in a safe way with ionizing radiations in medicine, industry and research, until the year 2013 have been organized 2231 courses that have allowed the training of 26213 people. The courses are organized according to the specific work that is carried out with radiations (medical radio-diagnostic, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear meters, logging while drilling, etc.). In their majority the courses are directed to people that will make use of radiations for first time, but refresher courses are also granted in the topic. The CSEN also carries out the Master degree programs highlighting the Second Professional Specialization in Radiological Protection carried out from the year 2004 with the support of the National University of Engineering. To the present has been carried out 2 programs and there is other being developed. In this work is shown the historical evolution of the radiological protection courses as well as the important thing that they are to work in a safe way in the country. (Author)

  19. Radiological safety in petroleum industry. Towards prevention culture

    2007-01-01

    Within the frame of regulatory control of industrial applications the audit of sealed and open radioactive sources in oil uses is one of the most relevant. The handling of radioactive sources, the requirement of procedures and training are just a few examples among all those that make up the radiological safety culture. A number of requirements divided into three main groups: operational safety at the storage area of radioactive sources, during transportation and during the applications (Cementation, well logging and use of radiotracers) are highlighted. Due to the great number of aspects that have to be taken in account as well as the interrelation of all control processes it is highly recommended that aspects of safety culture and quality should be considered and improvements regarding prevention, should be introduced so as to correct deviations that could arise in order to avoid radiological risk situations, emphasizing risk perception situations, attitude training, implementation of audit and level of safety in the facilities and control of duties, involving radiological material handling, described in the present work.

    The concepts of tolerability and reasonableness are at the core of the International Commission on Radiological Protection (ICRP) system of radiological protection. Tolerability allows the definition of boundaries for implementing ICRP principles, while reasonableness contributes to decisions regarding adequate levels of protection, taking into account the prevailing circumstances. In the 1970s and 1980s, attempts to find theoretical foundations in risk comparisons for tolerability and cost-benefit analysis for reasonableness failed. In practice, the search for a rational basis for these concepts will never end. Making a wise decision will always remain a matter of judgement and will depend on the circumstances as well as the current knowledge and past experience. This paper discusses the constituents of tolerability and reasonableness at the heart of the radiological protection system. It also emphasises the increasing role of stakeholder engagement in the quest for tolerability and reasonableness since Publication 103. © The International Society for Prosthetics and Orthotics.

    2008-01-01

    Key scientific challenges arising from ongoing radiobiological research have been identified recently. From this scientific base, the possible implications for radiological protection science are expected to be further elaborated. Through discussions among members of various NEA committees, it is clear that there is a need for radiological protection policy makers, regulators and practitioners to better understand possible developments coming from radiological protection science. At the same time, there is also a need for radiological protection scientists to better understand the broad processes of radiological protection decision making and to better interact with these processes in terms of furnishing input coming from their research. Participants in this workshop will attempt to identify elements of a framework that are better suited for the integration of new scientific and technological developments and socio-political considerations into radiological protection. This workshop initiated a process of reflection and dialogue among researchers, policy makers and other stakeholders that will, in the longer term: - improve understanding in both the research and policy communities of what is at stake in the system of radiological protection as scientific knowledge and social values evolve; - contribute to the development of a more shared view of emerging scientific and societal challenges to radiological protection, taking into account existing differences; - identify research that will better inform decision makers' judgments on emerging issues; - be the first step in the identification of elements of a framework that is better suited for the integration of new scientific and technological developments and socio-political considerations into radiological protection; and - identify the most appropriate next steps in this process. To achieve the above objectives, selected examples of emerging radiological protection issues were addressed during the workshop. The

    Protection against IR and NIR developed in completely different ways because of the very different evolution of the techniques they involve. While as soon as 1928, the International Society of Radiology created the International Commission of Radiological Protection, we had to wait until 1977 to see the creation of the International Committee for NIR (INIRC) by IRPA. To compare protection against Ionizing Radiations and Non Ionizing Radiations we will first carry out a general analysis of its components and then we will draw the general conclusions leading to a quite comparable evolution.

    2000-01-01

    Preparations for a LILW repository development in Croatia, conducted by APO Hazardous Waste Management Agency, have reached a point where the first safety assessment of the prospective facility is being attempted. For evaluation of the calculated radiological impact in the assessed option of repository development, a set of radiological protection criteria should be included in the definition of the assessment context. The Croatian regulations do not explicitly require that the repository development be supported by such safety assessment process, and do not provide a specific set of radiological criteria intended for the repository assessment which would be suitable for the constrained optimization of protection. For the initial safety assessment iterations of the prospective repository, which will address long term performance of the facility for various design and other safety options, we propose to use relatively simple radiological protection criteria, consisting only of individual dose and risk constraints for the general population. The numerical values for these constraints are established in accordance with the recognized international recommendations and in compliance with all possibly relevant Croatian safety requirements.

    Following the Fukushima-Daichi accident, several actions have been taken in France from the lessons learnt from the accident: the elaboration of a national plan for the management of a major nuclear or radiological accident, and the safety complementary evaluations to be carried out by nuclear operators. As a complement to the measures to be implemented for the protection of the overall population in emergency radiological situation, the protection of workers mobilized for the management of the crisis has also to be taken into account in the framework of these measures. The French Society of Radiation Protection (SFRP) has organized a technical day to take stock of this question. The program comprises 4 topical sessions dealing with: the main actions taken at the national scale after the Fukushima-Daichi accident, the strategies and intervention means of nuclear operators in case of radiological emergency, the radiation protection R and D for the protection of intervenors in case of radiological emergency, and the main actions implemented at the international scale and their perspectives. This document brings together the abstracts and the presentations (slides) of the different talks given at the meeting: 1 - Health status and lessons learnt from the Fukushima accident - workers (Alain RANNOU, IRSN); 2 - National response plan to a major nuclear or radiologic accident (Eric GOSSET, SGDSN); 3 - Legal framework applicable to intervenors (Thierry LAHAYE, DGT); 4 - Prescriptions linked with complementary safety and liability studies (Laurent FOUCHER, ASN); 5 - EDF: radiological risk management in emergency situation (Pascal BOUCHERY, EDF); 6 - CEA: intervention strategy, means and radiation protection (Xavier PECTORIN, Laurence FUSIL - CEA); 7 - AREVA: FINA's Intervention and workers' radiation protection (Bruno ADHEMAR, Patrick DEVIN - AREVA); 8 - Intervention in radiological emergency situation: the INTRA (Robots intervention on accidents) economic

    The public often regard radiation from nuclear facilities as more dangerous than that from natural sources or medicinal applications, but there is no scientific justification for this view. Operators of nuclear facilities endeavour to keep radiation releases at a level much below the limits specified in law. The latter are defined in such a way that the limit for public exposure to radiation is not exceeded even if very unfavourable assumptions were to apply. In its 10{sup th} Annual Report on Radiological Protection, the Swiss Federal Nuclear Safety Inspectorate (ENSI) analyses the release of radioactive materials from Swiss nuclear facilities. All nuclear facilities complied with the limits and in some cases by a very large margin. Fuel rod damage at the Leibstadt nuclear power station (KKL) did trigger higher releases of airborne iodine than in previous years. The Muehleberg power station must further reduce its waterborne releases of radiation. The Swiss Federal Office of Public Health (FOPH) has confirmed that these releases would not have affected public safety even if river or seawater had been used for drinking water. With the exception of the increase in the release of gaseous iodine at KKL, emissions from Swiss nuclear facilities were comparable with previous years and the annual dose to which young children in the immediate vicinity of nuclear facilities were exposed was less than 0.01 mSv. The main element contributing to these releases is the radioactive carbon isotope {sup 14}C produced by neutron reactions with nitrogen, carbon and oxygen. The low level of releases is due to the responsible actions of nuclear facilities in the fulfillment of their obligations with regard to radiological protection. The mean individual dose for those exposed to radiation during their work has not changed significantly in recent years and is at 0.6 mSv significantly below the limit for persons professionally exposed to radiation (20 mSv) and even the mean annual dose

    The International Commission on Radiological Protection (ICRP) has established Task Group 94 (TG 94) to develop a publication on the ethical foundations of the system of radiological protection aiming to consolidate the basis of ICRP's recommendations, to improve the understanding of the system and to provide a basis for communication on radiation risk and its perception. Through the review of the publications of the Commission and the conduct of a series of workshops, TG 94 has identified the key components of the ethical theories and principles relevant to the system of radiological protection. The purpose of eliciting the ethical values underpinning the system of radiological protection is not only to clarify the rationale of the recommendations made by the Commission, but also to assist in discussions related to its practical implementation. The report nearing completion by TG 94 will present the key steps concerning the scientific, ethical and practical evolutions of the system of radiological protection since the first ICRP publication in 1928, describe the core ethical values underpinning the present system and address the key procedural aspects for its implementation.

    2006-06-01

    The work of diagnostic radiology consists of the complete detection of all abnormalities in an imaging examination and their accurate diagnosis. Errors in diagnostic radiology comprise perceptual errors, which are a failure of detection, and interpretation errors, which are errors of diagnosis. Perceptual errors are subject to rules of human perception and can be expected in a proportion of observations by any human observer including a trained professional under ideal conditions. Current legal standards of medical negligence make no allowance for perceptual errors, comparing human performance to an ideal standard. Diagnostic radiology in Australia has a culture of open disclosure, where full unbiased evidence from an examination is provided to the patient together with the report. This practice benefits the public by allowing genuine differences of opinion and also by allowing a second chance of correct diagnosis in cases of perceptual error. The culture of open disclosure, which is unique to diagnostic radiology, places radiologists at distinct medicolegal disadvantage compared with other specialties. (i) Perceptual error should be acknowledged as an integral inevitable part of diagnostic radiology; (ii) culture of open disclosure should be encouraged by the profession; and (iii) a pragmatic definition of medical negligence should reflect the imperfect performance of human observers.

  10. New recommendations from the International Commission on Radiological Protection-a review

    2008-01-01

    For almost half a century, the International Commission on Radiological Protection (ICRP) has revised its recommendations on radiological protection with an average frequency of about 10 years, building on the experience gained in their implementation. This has ensured that the recommendations remain up to date and fit for purpose and it is this that has led in turn to their wide acceptance internationally. Indeed, the 1990 version of the recommendations forms the basis of the international radiological protection standards and the systems of control of exposure to ionizing radiation in many countries throughout the world. This version introduced new concepts and a more holistic approach to radiological protection but marrying the different exposure situations into one coherent framework has proved not to be straightforward and further reflection seemed necessary in order to satisfy both those who are responsible for the development of the control systems as well as a broader audience. Review of the 1990 recommendations started around 1998 and, since then, many ideas have been explored and avenues followed. Eventually, new recommendations were agreed by the Commission at its meeting in Essen in March 2007. This paper provides a review of these new recommendations and their possible implications.

    The Fukushima Daiichi nuclear power plant accident in March 2011 shook the radiological protection world. All major organisations in the radiological protection field turned their eyes to Japan. Their actions, driven by their mandates, are reflected in their respective landmark reports on the accident. Reports of the International Commission on Radiological Protection, World Health Organisation, United Nations Scientific Committee on the Effects of Atomic Radiation, and International Atomic Energy Agency are summarised. Collaboration between key international organisations is strong, based in part on informal interactions which need to be backed up with formal relations to ensure solid long-term collaboration.

    In the radiological protection report 2016, the Swiss Federal Nuclear Safety Inspectorate (ENSI) provides an overview of the radiological protection in its area of supervision. Part A of the report deals with protecting the staff of nuclear power plants from the dangers of ionising radiation. It also includes a list of the personal doses accumulated by the staff, broken down using various parameters. Applying the optimisation imperative, it has been proved possible to significantly reduce the annual collective doses in Switzerland's nuclear power plants since they came on stream thanks to major efforts by the operators. In 2016, a total of 6,153 people measured accumulated 2,877 person-mSv. The collective doses have reached a low level corresponding to the radiological condition of the plants and the scope of the work required to be performed in controlled zones (e.g. non-destructive materials testing). ENSI will continue to follow the trend for collective doses and assess the reasons for local variances as well as for measures initiated. The individual doses for people employed in ENSI's area of supervision in 2016 showed a maximum figure of 10 mSv and a mean value of 0.5 mSv which was significantly below the dose limit of 20 mSv for occupational radiation exposure. The discharge of radioactive substances with the exhaust air and waste water from nuclear power plants are dealt with in Part B of the report. In 2016, nuclear power plant operators again met the admissible release limits set by the authorities, in some cases by a considerable margin. The emissions of Swiss nuclear power plants led to a dose of less than 0.01 mSv per year in the direct neighbourhood. A comparison with the average annual radiation dose for the Swiss population of 5.5 mSv shows that the relevant contribution from nuclear power plants lies in the area of one percent of this figure. Effluents from Swiss nuclear power plants were also below the target of 1 GBq per year set by ENSI

    Standards in relation to radiological protection in medicine are well-documented, particularly with the recent update of the Basic Safety Standards. The principles of justification and optimisation remain key, as dose limitation is not applicable in medical practice. Appropriate justification relies on the knowledge, experience and discretion of the relevant medical practitioners and this may be overlooked in the race for diagnosis and treatment. One argument would be further regulation of medical exposures, although it is difficult to see how this could be imposed without denying patients essential investigations and treatments. Another contentious issue is individual patient dose management with the possible creation of a 'radiation passport'. Individual radiation susceptibility is a topic that has attracted much attention, but how to manage such persons, if identified, raises further questions. Communicating radiation risks and benefits to patients appropriately needs to be addressed, including who should be responsible for this, given accurate knowledge is a prerequisite. Ethics in radiological protection is also being widely discussed and this in relation to medical practice, which already involves numerous ethical issues, is likely to be open to debate in the near future.

  15. Issues around radiological protection of the environment and its integration with protection of humans: promoting debate on the way forward

    Brownless, G P

    2007-01-01

    This paper explores issues to consider around integrating direct, explicit protection of the environment into the current system of radiological protection, which is focused on the protection of humans. Many issues around environmental radiological protection have been discussed, and ready-to-use toolboxes have been constructed for assessing harm to non-human biota, but it is not clear how (or even if) these should be fitted into the current system of protection. Starting from the position that the current approach to protecting the environment (namely that it follows from adequately protecting humans) is generally effective, this paper considers how explicit radiological protection of the environment can be integrated with the current system, through developing a 'worked example' of how this could be done and highlighting issues peculiar to protection of the environment. The aim of the paper is to promote debate on this topic, with the ultimate aim of ensuring that any changes to the system are consensual and robust

    Full text of publication follows: In the framework of the international C.O.R.E. programme (Cooperation for Rehabilitation of living conditions in Chernobyl affected areas in Belarus), an educational project was launched in 2004 meant so that the pupils of the Bragin district schools (in the south east of Belarus) will get involved in learning the practice of a radiological culture. Since the damages of radioactivity are cumulative, it is important to reduce the inhabitants daily intake of radioactivity. In the daily life, the understanding of radioactivity issues and the current recommendations concerning food and the environment are not always applied and accessible to the public. By showing that monitoring could help them to reduce the dose of radioactive elements, this project aims at breaking a fatalistic turn of mind. A steady radioecological education is the key element in establishing a practical radiological culture within the population. This project is essentially centred on children who represent both the future generation and the most sensitive group among contaminated by the radioactive effect. Children represent also the best way to realise in -depth contact with the whole population. To facilitate the development of the educational projects, Belarus teams of teachers will receive in -depth expert training in cooperation of the local professionals which will enable them to become active participants in conceiving and carrying out their own educational projects. A more specific training, concerning radiation protection is also be implemented by our N.G.O., with the help of the local organisation Rastok Gesne (Sprout of Life N.G.O.). The pedagogic actions are based on a complete and active involvement of the children and within an interdisciplinary approach will make it possible to include the different activities linked to radiological culture, and more widely, all the other aspects of living in a contaminated area so as to be able to face the risk

    Safety culture or radiation protection culture is based in common on the term, 'culture'. Culture is defined as the learned, shared set of symbols and patterns of basic assumptions, which is invented, discovered, or developed by a given group as it learns to cope with its problem of external adaptation and internal integration. Safety culture generally refers to the attitude and behaviors affecting safety performance. The concept of 'Safety Culture' was introduced after the Chernobyl accident in 1986. For the accident, nuclear society reached the conclusion that the cause was the wrong management attitude of the NPP, that is, deficient 'Safety Culture'. Recently, 'Radiation Protection Culture' was introduced as the core concept of nuclear safety culture. There have been many efforts to establish definition and develop assessment tool for radiation protection culture in international level such as ICRP and IRPA as well as NRC. In the same context with the safety culture, radiation protection culture is defined as 'the core values and behaviors resulting from a collective commitment by leaders and individual's to emphasize safety over competing goals to ensure protection of people and the environment.' It is worthwhile to recognize that regulatory enforcement in establishing healthy radiation protection culture of operators should be minimized because culture is not in the domain of regulatory enforcement. However, as 'ALARA', the most important concept in radiation protection, may be successfully achieved only in well established radiation protection culture, the least regulatory intervention would be needed in promoting and nurturing radiation protection culture in licensee. In addition, the concept of radiation protection culture should be addressed in plant operational policy to achieve the goals of ALARA.

    The paper discusses the role of the IAEA in relation to the radiological protection of patients. Within the IAEA there are two major programmes which have an impact on the protection of the patient. Firstly, patient protection is part of the programme on radiation safety; secondly, the human health programme contains a number of activities related to quality assurance (QA), and these also contribute to the protection of patients. A function of the IAEA, as stipulated in its Statute, is 'to establish or adopt, in consultation and, where appropriate, in collaboration with the competent organs of the United Nations and with the specialized agencies concerned, standards of safety for protection of health and minimization of danger to life and property' and to provide for the application of these standards...'. There are three different levels of the IAEA Safety Standards: Safety Fundamentals, Safety Requirements and Safety Guides. The Standards are supported by other documents such as Safety Reports. There are five means used by the IAEA in providing for the application of the Standards: co-ordinating research, promoting education and training, providing assistance, fostering information exchange and rendering services to its Member States. All these means are used in the programme on radiological protection of patients as described in the paper. The IAEA is assisting its Member Sates in the development and implementation of QA programmes. These activities help disseminate not only the technical knowledge but also the basic ingredients of the QA culture. The IAEA assistance is directed at: (1) national regulatory bodies for the establishment of a regulatory framework which complies with the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources; (2) standards laboratories for metrological traceability; and (3) end users at medical institutions for the development and implementation of QA programmes

    This study aimed to evaluate the integrity of radiological protection clothing used by veterinarians in veterinary radiology facilities, and whether they are available in an adequate quantity for the team. Inspection was performed by palpation, followed by X-ray scanning in 189 clothing from 29 veterinary facilities. The results indicate that 5% of the clothes evaluated in this study were considered inadequate due to the failure of the integrity of the lead, being most lead aprons. All facilities have at least two lead aprons and one Thyroid protectors. 24% of the facilities have lead glasses, pointing to a risk to veterinarians by radiosensitivity of the eyes. Also, 24% of the facilities do not have lead gloves, which also presents a risk due to the hand's exposure to the primary beam. Most lead clothing has shield equivalence of 0.5mmPb. The method used in the study was effective in attesting the adequacy of lead clothing. It is recommended to periodically evaluate clothing to ensure that users are always protected. (author)

The results indicate that 5% of the clothes evaluated in this study were considered inadequate due to the failure of the integrity of the lead, being most lead aprons. All facilities have at least two lead aprons and one Thyroid protectors. 24% of the facilities have lead glasses, pointing to a risk to veterinarians by radiosensitivity of the eyes. Also, 24% of the facilities do not have lead gloves, which also presents a risk due to the hand's exposure to the primary beam. Most lead clothing has shield equivalence of 0.5mmPb. The method used in the study was effective in attesting the adequacy of lead clothing. It is recommended to periodically evaluate clothing to ensure that users are always protected. (author)

    Following the Fukushima accident, the International Commission on Radiological Protection (ICRP) convened a task group to compile lessons learned from the nuclear reactor accident at the Fukushima Daiichi nuclear power plant in Japan, with respect to the ICRP system of radiological protection. In this memorandum the members of the task group express their personal views on issues arising during and after the accident, without explicit endorsement of or approval by the ICRP. While the affected people were largely protected against radiation exposure and no one incurred a lethal dose of radiation (or a dose sufficiently large to cause radiation sickness), many radiological protection questions were raised. The following issues were identified: inferring radiation risks (and the misunderstanding of nominal risk coefficients); attributing radiation effects from low dose exposures; quantifying radiation exposure; assessing the importance of internal exposures; managing emergency crises; protecting rescuers and volunteers; responding with medical aid; justifying necessary but disruptive protective actions; transiting from an emergency to an existing situation; rehabilitating evacuated areas; restricting individual doses of members of the public; caring for infants and children; categorising public exposures due to an accident; considering pregnant women and their foetuses and embryos; monitoring public protection; dealing with ‘contamination’ of territories, rubble and residues and consumer products; recognising the importance of psychological consequences; and fostering the sharing of information. Relevant ICRP Recommendations were scrutinised, lessons were collected and suggestions were compiled. It was concluded that the radiological protection community has an ethical duty to learn from the lessons of Fukushima and resolve any identified challenges. Before another large accident occurs, it should be ensured that inter alia: radiation risk coefficients of

    For the exposure of patients in diagnostic radiology, individual dose limit does not apply, but optimization of radiological protection may play a major role. This project has been carried out with the purpose of improving the protection of patients in medical diagnostic radiology in China utilizing the principles of optimization. Taking Sichuan, Shandong and Beijing as surveyed areas, we investigated the present situation of the protection of patients. In the survey, the patient doses were classified into practical dose, justified dose and optimized dose to evaluate the influences of managerial and equipment factors separately. The results show that there are some urgent protection problems in X-ray protection to be solved in the surveyed regions. This paper, however, points out that the prospects of reducing patient doses are encouraging provided that appropriate measures are adopted. For instance, taking proper managerial measures without radical change of existing equipments may reduce patient doses in chest fluoroscopy and radiography by 40% and 18% respectively; refitting some equipment may reduce the doses by 82.4% in chest fluoroscopy, 66% in chest radiography, and 80% in barium meal examination of the gastrointestinal (GI) tract. Using chest radiography instead of fluoroscopy supplemented by other protection measures may reduce the doses by 91.7%. Optimization analysis shows that adoption of the above measures conforms to the principle of optimization of radiation protection. (authors). 5 refs., 7 tabs

  7. Protective effect of lead aprons in medical radiology

    This article summarizes the results of an ongoing study regarding the protective effect that lead aprons, as used in medical radiology, have on the resulting effective dose for medical personnel. By means of model calculations we have analyzed the protection efficacy of lead aprons for various lead thicknesses, in function of tube potential and of variations in exposure geometry as they occur in practice. The degree of efficacy appears to be highly dependent on the fit of aprons because of the dominating influence of the equivalent dose of partially unshielded organs on the resulting effective dose. Also by model calculations we investigated the ratio between the effective dose and the operational quantify for personal dose monitoring. Our study enables the choice of appropriate correction factors for convering personal dosimetry measurements into effective dose, for typical exposure situations in medical radiology. (orig.) [de

    The Radiological Protection Plan - PPR, quoted by the Regulatory Standard 32, requires to be maintained at the workplace and at the disposal of the worker's inspection the PPR, for it to be aware of their work environment and the damage that can be caused by misuse of ionizing radiation. Objective: to discuss the interface between PPR and ethical reflection. Method: this is a reflective study. Discussion and results: regulatory norm 32 points out that the worker who conducts activities in areas where there are sources of ionizing radiation should know the risks associated with their work. However, it is considered that the sectors of hospital radiology the multidisciplinary health team is exposed to ionizing radiation and has not always aware of the harm caused by it, so end up unprotected conduct their activities. Concomitantly, recent studies emphasize the radiological protection and concern for the dangers of radiation on humans, but rather refer to the legislation about the radiological protection. In this context an ethical reflection is necessary, seeking to combine work ethics liability to care in protecting themselves and the other with the institutional conditions for this protection becomes effective.

    The aim of the radiological environment protection is to avoid risks to the health of the population. But the risks from radiation can only be considered in connection with spontaneously occuring malignancies. The comparison shows that according to the maximum permissible doses in the German Ordinance of Radiation Protection the risks of radiation injury are so low that they cannot be detected relative to the spontaneous malignancies.

    This paper aims to show the radiological protection development in Brazil from the beginning, when President Joao Cafe Filho signed an agreement with the U.S.A. In this agreement, Brazil joined the 'Atoms for Peace' program established on August 3., 1955. Yet in 1955, Brazil participated as a foundation member in the International Atomic Energy Agency (IAEA). As a result, the Iea - 'Instituto de Energia Atomica'- was created on August 31., 1956 and a research reactor type swimming pool was installed to produce radioisotopes and prepare experts in the field of nuclear activities. This reactor is maintained in operation at the Instituto de Pesquisas Energeticas e Nucleares (IPEN), former Iea. Having the Iea as a case of study, we analyze the radiological protection evolution during the fifty years of its life. We correlate this development with the Brazilian National Nuclear Energy Commission (CNEN) Regulations. CNEN was also created in 1956. The first safety standard in Brazil was delivered in 1973. Therefore, this paper will focus the radiological protection development at national level. Both institutions followed the international radiological protection recommendations, under the difficulties imposed by the historical conditions of a developing country. In order to have an outline of the radiological protection development, we inform that it was started as a section of the Radiological Division at the Iea. At that time, the Iea had four divisions. The radiological protection was performed by four people, being two physicists and two technicians that accomplished all the duties. On that occasion, approximately 30 people operated the Iea. The work staff at IPEN increased, arriving to 1600 people in 1998, including 150 persons in the radiological protection activities. Nowadays, 1200 people, including 100 persons in the health physics duties operate the IPEN. (authors)

    The Pan American Health Organization/World Health Organization (PAHO/WHO), founded in 1902, initiated a radiological health programme in the 1950s. Within this programme, there are currently three lines of work: (a) radiology services; (b) radiation safety; and (c) radiological emergencies. Radiology services deals with health services for diagnostic and interventional imaging, and for radiation therapy. Radiation safety studies the three types of exposures to both ionizing and non-ionizing radiation: occupational; medical; and public. Radiological emergencies involve radioactive waste management programmes and emergency plans. The radiological protection of patients is addressed in each of these areas: (a) when analysing the infrastructure of radiology services; and (b) when determining medical exposures; and (c) when investigating overexposures in interventional or therapeutic procedures or under-doses in radiation therapy.

    The role of the CDTN/CNEN as far as the radiological protection services in the medical and dental radiology has changed a lot due to the new Regulatory Directives. The CDTN/CNEN was recognized as the regional reference center for providing not only radiological survey services, but to coordinate an accreditation procedure for professional persons to be accepted by the State Regulatory Authorities to work at Minas Gerais. All the new activities were formalized in a Cooperation Agreement between the CDTN/CNEN and the Regulatory Authority. This paper describes the accreditation procedure for candidates, the adopted requirements, the intercomparison results among measuring instruments and the main achievements during the first year of the Agreement.

    The OECD Nuclear Energy Agency (NEA) has actively participated in discussions with the International Commission on Radiological Protection (ICRP) regarding the development of new recommendations that will replace those in ICRP Publication 60, which has long served as the international standard in this field. Part of this development process has involved the organisation of seven international workshops, including the First and Second Asian Regional Conferences on the Evolution of the System of Radiological Protection which took place in Tokyo, Japan in October 2002 and July 2004. The Third Asian Regional Conference was held on 5-6 July 2006, also in Tokyo. The main objective of these conferences was to ensure that the views and concerns of relevant Asian stakeholders, such as regulatory authorities, industry, professional societies and NGO, could be expressed and discussed with the ICRP. The three conferences provided the ICRP with specific views on how new recommendations could best be developed to address regulatory and implementation needs in the Asian context. These proceedings summarize the results and key discussions of the Third Asian Regional Conference. (author)

    In the 2015 annual report on radiological protection, the Swiss Federal Nuclear Safety Inspectorate (ENSI) reports on occupational radiation doses, releases of radioactive material and the monitoring of environmental radiation in the areas subject to its surveillance. It concludes that Swiss nuclear facilities continue to maintain a consistent approach to radiological protection. ENSI has identified an increasing public interest in data concerning radiation and has therefore introduced a number of new concepts, such as the online availability of monthly nuclear power plant releases. There is also a new development concerning the data from the network for automatic measurement of dose rates in the vicinity of nuclear power plants (MADUK) which has been in operation since 1994. It is now possible to view dose rates since 1994 averaged over periods of ten minutes, one hour and one day. A special chapter of this report deals with {sup 14}C releases, which are the subject of enquiries from interested parties. The mean annual individual occupational radiation dose remains at 0.6 mSv, being significantly less than the mean annual radiation dose of the population in Switzerland of 5.5 mSv. The highest annual individual dose was almost 11 mSv so that once again in 2015 the annual limit of 20 mSv was not exceeded. The collective doses lie within the range of past years. However, the trend towards a higher collective dose noted at the Leibstadt Nuclear Power Plant has continued. Planning by the operators of nuclear facilities in the field of radiological protection is of a high standard so that the resulting collective doses generally closely match the projected values. In 2015, nuclear power plant operators have again complied with the release limits specified by the authorities, to some extent by a considerable margin. Emissions from Swiss nuclear power plants resulted in a dose of less than 0.01 mSv per year in their immediate surroundings. Liquid releases from Swiss

    Paediatric patients require special attention with respect to radiation protection, for various reasons. The difference between a 1 kg premature baby and a 100 kg teenager puts special demands on the radiographic techniques used, and the increased radiosensitivity of growing tissue and the patients' longer life expectancy put greater demands on the justification of the procedures to be carried out. The optimization procedure involves practical aspects such as immobilization, body build specific exposure parameters and body build specific anatomical knowledge. These and other aspects of paediatric radiological protection are discussed in this overview. (author)

    Some studies for radiological protection of the environment have been made at the National Inst. of Radiological Sciences (NIRS). Transfer of radionuclides and related elements has been investigated for dose estimation of non-human biota. A parameter database and radionuclide transfer models have been also developed for the Japanese environments. Dose (rate)-effect relationships for survival, growth and reproduction have been investigated in conifers, Arabidopsis, fungi, earthworms, springtails, algae, duckweeds, daphnia and medaka. Also genome-wide gene expression analysis has been carried out by high coverage expression profiling (HiCEP). Effects on aquatic microbial communities have been studied in experimental ecosystem models, i.e., microcosms. Some effects were detected at a dose rate of 1 Gy day -1 and were likely to arise from inter-species interactions. The results obtained at NIRS have been used in development of frameworks for environmental protection by some international bodies, and will contribute to environmental protection in Japan and other Asian countries.

    Management of radiation-induced risks in areas contaminated by a nuclear accident is characterized by three ethical issues: (1) risk trade-off, (2) paternalistic intervention and (3) individualization of responsibilities. To deal with these issues and to clarify requirements of justification of interventions for the purpose of reduction in radiation-induced risks, we explored the ethical basis of the radiological protection system of the International Commission on Radiological Protection (ICRP). The ICRP's radiological protection system is established based on three normative ethics, i.e. utilitarianism, deontology and virtue ethics. The three ethical issues can be resolved based on the decision-making framework which is constructed in combination with these ethical theories. In addition, the interventions for inhabitants have the possibility to be justified in accordance with two ways. Firstly, when the dangers are severe and far-reaching, interventions could be justified with a sufficient explanation about the nature of harmful effects (or beneficial consequences). Secondly, if autonomy of intervened-individuals can be promoted, those interventions could be justified. (author)

    Full text: One of the main recommendations of the Congress of Malaga on Radiological Protection of the Patient is 'the qualification and training of the staff'. This goal cannot be reached in a country, in complete and systematic form, without the help of existing national programs who allow designing a program of continuous development of the professional capacities. This program must be able to adapt in permanent form to the needs of the Program of Radiological Protection of the Patient that change and evolve in constant form. In case of the Argentina it was adapted to these needs the 'National Program of Certification and Re-certification of medical professionals in Radiology and Radio-Diagnosis'. On the base of the existing program, general requirements were established for the radiological protection of the patient and in addition, special requirements for four specialties: a) General and pediatrics radiology; b) Computed tomography; c) Interventional radiology; d) Radiotherapy. The National Program of Certification was established in 1997 with a 'Top Permanent Council' formed by the National Minister of Health advised by a scientific council. It was also creates the 'National Council of Certification and professional Re-certification' integrated by the Minister of Education, the National Academy of Medicine, the Faculties of Medicine of the whole country, the medical Federations, the trade-union Associations and the Argentine Medical Association. The process of certification can be delegated to academic or university entities, medical colleges and medical chambers that have been recognized path and ethical conduct. The certification is voluntary but it becomes obligatory to be recognized as a specialist. The certification has duration of 5 years and is renewable on the basis of a system of credits that considers different elements of the developed activities and the written theoretical and practical evaluations. It is a transparent process where the ethical

    The current system of radiological protection based on the Linear No-Threshold (LNT) hypothesis has greatly contributed to the minimization of doses received by workers and members of the public. However, it has brought about r adiophobia a mong people and waste of resources due to over-regulation, because the LNT implies that radiation is harmful no matter how small the dose is. The author reviewed the results of research on health effects of radiation including major epidemiological studies on radiation workers and found no clear evidence of deleterious health effects from radiation exposures below the current maximum dose limits (50 mSv/y for workers and 5 mSv/y for members of the public), which have been adopted worldwide in the second half of the 20th century. Now that the existence of bio-defensive mechanisms such as DNA repair, apoptosis and adaptive response are well recognized, the linearity assumption cannot be said to be s cientific . Evidences increasingly imply that there are threshold effects in risk of radiation. A concept of practical thresholds or virtually safe doses will have to be introduced into the new system of radiological protection in order to resolve the low dose issues. Practical thresholds may be defined as dose levels below which induction of detectable radiogenic cancers or hereditary effects are not expected. If any workers and members of the public do not gain benefits from being exposed, excepting intentional irradiation for medical purposes, their radiation exposures should be kept below practical thresholds. On the assumption that the current dose limits are below practical thresholds and with no radiation detriments, there is no need of justification and optimization (ALARA) principles for occupational and public exposures. Then the ethical issue of justification to allow benefit to society to offset radiation detriments to individuals can be resolved. And also the ethical issue of optimization to exchange health or safety for

    Introduction: The dental radiology represents about 20% of human exposure to radiation in radio diagnostic. Although the doses practiced in intraoral dentistry are considered low, they should not be ignored due to the volume of the performed procedures. This study presents the radiation protection conditions for intraoral radiology in Curitiba - PR. Methods: Data was collected through a quantitative field research of a descriptive nature during the period between September of 2013 and December of 2014. The survey sample consisted of 97 dentists and 130 intraoral equipment. The data related to the equipment was collected using structured questions and quality control evaluations. The evaluations of the entrance skin dose, the size of the radiation field and the total filtration were performed with dosimetry kits provided and evaluated by IRD/CNEN. The exposure time and voltage were measured using noninvasive detectors. The occupational dose was verified by thermoluminescent dosimeters. The existence of personal protection equipment, the type of image processing and knowledge of dentists about radiation protection were verified through the application of a questionnaire. Results: Among the survey's results, it is important to emphasize that 90% of the evaluated equipment do not meet all the requirements of the Brazilian radiation protection standards. Conclusion: The lack of knowledge about radiation protection, the poor operating conditions of the equipment, and the image processing through visual method are mainly responsible for the unnecessary exposure of patients to ionizing radiation.

    Man first became aware of the invisible radiation surrounding him in 1895, when Wilhelm Roentgen showed that a photographic plate could be affected by an invisible radiation capable of passing through matter. He called this radiation 'X-rays' from X, the unknown. Doctors immediately saw the usefulness of this type of radiation and began to use it in medical research. This was the birth of radiology. 'Mankind has been exposed to radiation since his first appearance on Earth. We first became aware of this at the end of the 19. century'. However, it was not long before some of the doctors and radiologists treating their patients with X-rays began to fall ill. It began to be understood that exposure to high doses of radiation was dangerous and protective measures were necessary. From the 1920's onwards, international commissions were established to specify regulations for the use of radiation and for the radiological protection of personnel. (authors)

    Since the publication of ICRP 22 and ICRP 26 in 1973 and 1977 respectively, the understanding and practical implementation of the concept of Optimisation of Radiation Protection known as ALARA ('as low as reasonably achievable') has developed considerably globally and particularly in Europe. In the 1990 ICRP 60 publication, ALARA was re-emphasised as the cornerstone of the radiological protection system. This is also an explicit requirement of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (International BSS) and EC Directive laying down the Basic Safety Standards for radiological protection (EURATOM Directive 96/29), as well as of most of the national regulations. Throughout the 1980's and early 1990's ALARA was integrated into many organisations' radiation protection programmes, particularly in the nuclear industry and mainly for managing occupational exposure. One of the main lessons identified from that period was that it was not possible to implement good radiological protection by relying only on technical rules and procedures summarised in the three words: 'Time-Distance-Shielding'. A fourth word, 'Commitment', was to be added as no radiological protection programme would be successful without the commitment of all concerned stakeholders: regulatory bodies, managers, workers, etc. The scope of this presentation is, through different international feedback experiences, to demonstrate how networking is an efficient, modern way of fostering stakeholders involvement in implementing good radiological protection.

    Radiological protection training addressed to physicians should start during the teaching graduate and postgraduate studies, and a third phase only for those physicians using X rays and radioactive sources in diagnosis and treatment of diseases. To show a training project addressed to the teaching graduate students based on the new technologies, such as web online and interactive CD-ROM. Development of a web-online including information in.pdf (adobe acrobat) format and additional tools (as data bases, videos, news and class meetings, FAQ, tutorials). Moreover, we propose to development an interactive CD-ROM which will be used as a practical tool to complete the obligatory subject on radiological protection in the University of Malaga (Spain). We show the preliminary phase of the project. The web-online is being developed with the Microsoft FrontPage software. The first version of the CR-ROM is being developed in html format. These tools based on new technologies will be a very important support for radiological protection training, which is recommended by International Organizations (EC Report R116 and IAE Action Plan 2002-2006).

    Objective: To determine the level of quality in radiation protection of patients during radiological examination, evaluating the effectiveness of an intervention aimed at enhancing the quality of such a protection. Materials and Methods: A quality improvement cycle was implemented in a radiology service of the Regional Health Administration, in Algarve, Portugal. Based on six quality criteria, an initial evaluation was performed and followed by an intervention focused on the most problematic points (over an eight-month period) and a subsequent quality reassessment. A random sampling (n = 60) has allowed the authors to infer the point estimates and confidence intervals for each criterion, as well as calculating the statistical significance of the results by means of the Z-test. Results: Initially, deficiencies were observed in relation to all the quality criteria. After the intervention, a minimum relative improvement of 33% was observed in five of the six criteria, with statistical significance (p < 0.05) in two of them. The absolute frequency of noncompliance decreased from 38 (first evaluation) to 21 (second evaluation), corresponding to a 44.7% improvement. Conclusion: The first institutional evaluation cycle showed a seemingly incipient improvement margin. However, the implemented intervention was effective in stimulating good practices and improving the level of radiological protection of patients. (author)

    Due to its very particular characteristics, industrial radiography is responsible for roughly half of the relevant accidents in nuclear industry, in developed as well as in developing countries, according to the International Atomic Energy Agency (IAEA). Thus, safety and radiological protection in industrial gamma radiography have been receiving especial treatment by regulatory authorities of most Member States. The main objective of the present work was to evaluate, from the radioprotection point of view, the main advantages of computed radiography (CR) for filmless industrial radiography. In order to accomplish this, both techniques, i.e. conventional and filmless computed radiography were evaluated and compared through practical studies. After the studies performed at the present work it was concluded that computed radiography significantly reduces the inherent doses, reflecting in smaller restricted areas and costs, with consequent improvement in radiological protection and safety.

  6. Contribution of the french society of radiological protection to the current reflections on the possible improvement of the radiological risk management system

    2000-01-01

    Following the invitation by IRPA to comment the article by Prof. R. Clarke entitled 'Control of Low Level Radiation Exposures: Time for a Change?', the Board of the French Radiological Protection Society (SFRP) has decided to set up a specific Working Group. This Group consists of some twenty members representing the stakeholders involved in radiological protection in France. Its goal is, starting from an analysis of R. Clarke's text, to formulate questions and proposals to assist ICRP in making its radiological protection system more understandable and more efficient. The aim of this review is not to restart from scratch but to consolidate and improve the existing system. The Working Group has therefore focused its thoughts on the following four points: 1. The basis of the radiological risk management system. In the absence of scientific certainty as to the effects of low doses of radiation, a prudent attitude has been adopted as to the manner of managing the radiological risk, based on the hypothesis that the dose-effect relationship is linear with no threshold. The Group discusses this basic assumption and its implications on the elaboration of the objectives of the radiological risk management system. 2. Exposure situations. Exposure situations are multifarious and the existing system divides them into categories for management purpose (e.g. practice/intervention; natural/artificial; medical/public/occupational; actual exposure/potential exposure; etc.). Some of these divisions are pertinent but some are less so and the Group examines if another way of conceptualising exposures situations could be more efficient. 3. Risk management indicators and tools. The radiological protection system provides the professionals with a series of indicators and tools, enabling them to manage exposure situations (dose, dose limit, dose constraint, individual dose, collective dose, investigation level, action level, interventional level, exemption level, clearance level

    2001-01-01

    The first international conference specifically focused on the radiological protection of patients will be held in Torremolinos (Malaga), Spain, next week, from 26 to 30 March 2001. The conference, formally titled, 'International Conference on the Radiological Protection of Patients in Diagnostic and Interventional Radiology, Nuclear Medicine and Radiotherapy', is being organized by the IAEA, hosted by the Government of Spain and co-sponsored by the European Commission, the Pan American Health Organization and the World Health Organization. Medical applications of ionizing radiation are accepted world-wide as essential tools for keeping or restoring human health. However, they also represent by far the largest man-made source of radiation exposure. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) estimates that diagnostic medical applications of radiation account for about 95% of the exposure to radiation from man-made sources of radiation and about 12% of total exposure, which includes the exposures received from natural sources. More than 900 participants from 80 countries are expected to attend the conference. They cover a broad spectrum of expertise, including radiologists, nuclear medicine specialists, radiation oncologists, medical physicists, technologists/radiographers, radiological protection officers, equipment manufacturers, experts who develop standards for radiological equipment, hospital administrators and public health officials and representatives of professional societies. In addition, a number of patients who have undergone radiation treatment will represent patients' interests and a patient will chair one of the round table debates. The conclusions of the Conference will be incorporated into the IAEA's programme of work in the field of radiation safety and will be reported to the IAEA General Conference at its next meeting in September 2001

  11. The regulatory application of authorization in radiological protection

    Lazo, T.; Frullani, S.

    2004-01-01

    Authorization is the process used by governments and regulatory authorities to decide what regulatory controls or conditions, if any, should be applied to radioactive sources or radiation exposure situations in order to protect the public, workers and the environment appropriately. Over the years, governments and regulatory authorities have used various approaches to the authorization process under differing circumstances. Now, with the new draft recommendations from the International Commission on Radiological Protection (ICRP), there is the prospect of being able to use a single, simple and self-coherent approach for the process of regulatory authorization under all circumstances. Previously, the ICRP recommended the use of various approaches to manage radiological protection situations. For what were called practices, exposures were subject to limits, and optimisation was required below these limits. What were called interventions were subject to intervention levels, above which some action could be considered justified, and which should be optimised based on consideration of how much dose could be averted by the countermeasure considered. Radon in homes was subject to action levels, above which some sort of countermeasure could be recommended. These approaches are all philosophically distinct and logically constructed, but their differences, particularly in the types of numerical criteria used (limits, intervention levels, action levels, etc.) contributed to confusion and misunderstanding.

    This annual report issued by the Swiss Federal Nuclear Inspectorate (ENSI) reports on the work carried out by ENSI in 2008. It provides comprehensive data on radiation protection activities in Switzerland during the year 2008. The first section of the report provides comprehensive data on radiation protection and deals with exposure rates for personnel and individual jobs. The authors note that, in recent years, both collective doses and average individual doses have declined by a factor of two. Radiation doses are commented on as being significantly lower than the maximum annual limit for persons exposed to radiation in the course of their work. Radiation in the four Swiss nuclear power stations and in four further nuclear installations in various Swiss research facilities is commented on. The Swiss radiation measurement network is commented on and the results obtained are discussed. ENSI concludes that the new recommendations published by the International Commission on Radiological Protection (ICRP 103) did not necessitate any significant changes in its surveillance activities.

    This report updates and consolidates previous recommendations of the International Commission on Radiological Protection (ICRP) related to solid waste disposal (ICRP, 1985, 1997b, 1998). The recommendations given apply specifically to geological disposal of long-lived solid radioactive waste. The report explains how the ICRP system of radiological protection described in Publication 103 (ICRP, 2007) can be applied in the context of the geological disposal of long-lived solid radioactive waste. Although the report is written as a standalone document, previous ICRP recommendations not dealt with in depth in the report are still valid. The 2007 ICRP system of radiological protection evolves from the previous process-based protection approach relying on the distinction between practices and interventions by moving to an approach based on the distinction between three types of exposure situation: planned, emergency and existing. The Recommendations maintains the Commission's three fundamental principles of radiological protection namely: justification, optimisation of protection and the application of dose limits. They also maintain the current individual dose limits for effective dose and equivalent dose from all regulated sources in planned exposure situations. They re-enforce the principle of optimisation of radiological protection, which applies in a similar way to all exposure situations, subject to restrictions on individual doses: constraints for planned exposure situations, and reference levels for emergency and existing exposure situations. The Recommendations also include an approach for developing a framework to demonstrate radiological protection of the environment. This report describes the different stages in the life time of a geological disposal facility, and addresses the application of relevant radiological protection principles for each stage depending on the various exposure situations that can be encountered. In particular, the crucial factor that

    Operational experience has shown that the mobile scintigraphy sector is not only that where individual doses are highest but also where there are the greatest number of high doses, overdoses and incidents. This fact highlights the need for improvement in the optimisation of radiological protection in the sector. In this context the CSN has adopted and implemented an action plan aimed at reducing doses to operation staff. (Author)

    The use of radiotracers plays an important role to provide methods to optimize industrial process and improve product quality. An increase in the use of radiotracers investigations has been observed in Brazil, however, as there is no specific standard for the licensing of these facilities, generic radiation protection regulations have been used, but these are not comprehensive or technically suitable for this purpose. Regulatory inspections in radiotracer facilities have reported failures in disagreement with best practices for radiological safety, mainly in radioactive waste management and in the control of workplaces during radiotracer injections. In this work, an assessment of radiological protection aspects of radioactive tracers is performed, based on the licensing process of radiotracers facilities, as well as the experience of regulatory inspections and a review of international standards, pointing out relevant radiation safety aspects for working practices, procedures and protective measures before, during and after injections of radioactive tracers, in order to contribute to the future development of specific safety regulations on radiotracers in Brazil.

Potential exposure is regarded as an part of radiological protection system in this new recommendations, in a practice, it can be significantly reduced by proper prevention and mitigation measures in design and management. It is pointed out that with modern safety technology, the probability of potential exposure situations can be lowered to many orders of magnitude, even though the estimated value of probability is not accurate. Situations requiring intervention and the principles in protection are also discussed

    The Hot Cells Laboratory (LCC) located in the National Institute of Nuclear Research are an installation that was designed for the management at distance of 10,000 Curies of Co-60 or other radioactive materials with different values in activity. The management of such materials in the installation, implies to analyze and to determine the doses that the POE will receive as well as the implementation of protection measures and appropriate radiological safety so that is completed the specified by the ALARA concept. In this work it is carried out an evaluation of the doses to receive for the POE when managing radionuclides with maximum activities that can be allowed in function of the current conditions of the cells and an evaluation of results is made with the program of surveillance and radiological protection implemented for the development of the works that carried out in the installation.

    In 1992 a joint venture between the Royal College of Radiologists (RCR) and the National Radiological Protection Board (NRPB) resulted in the formation of a Working Party (WP) to consider dental radiology. Although individual doses to patients are low, WP identified considerable scope for reducing the collective dose to patients and for improving the diagnostic quality of radiographs. The report published in the Documents of the NRPB series presents the WP conclusions in the form of guidelines that deal with all aspects of dental radiology in primary dental care. (Author)

    Eleven institutions of education and research in Brazil use particle accelerators, which fulfill different functions and activities. Currently, these institutions employ a total of fifteen accelerators. In this paper, the object of study is the radiological protection of occupationally exposed individuals, the general public and the radiation safety of particle accelerators. Research facilities with accelerators are classified in categories I and II according to the International Atomic Energy Agency or groups IX and X in accordance with the Brazilian National Commission of Nuclear Energy. Of the 15 accelerators in use for research in Brazil, four belong to category I or group X and eleven belong to category II or group IX. The methodology presented and developed in this work was made through the inspection and assessment of safety and radiological protection of thirteen particle accelerators facilities, and its main purpose was to promote safer use of this practice by following established guidelines for safety and radiological protection. The results presented in this work showed the need to create a program, in our country, for the control of safety and radiological protection of this ionizing radiation practice. (author)

    Protection of the environment is developing rapidly at the national and international level, but there are still no internationally agreed recommendations as to how radiological protection of the environment should be carried out. The International Commission on Radiological Protection (ICRP) is currently reviewing its existing recommendations for human protection. It has set up a task group with the aim of developing a protection policy for, and suggesting a framework of, the protection of the environment that could feed into its recommendations at the start of the 21st century. The task group will propose a framework for the protection of the environment from harmful effects of radiation, harmonising with the principles for the protection of humans. Although the task group has not yet finalised on the objectives for the environment, these might be to safeguard the environment by preventing or reducing the frequency of effects likely to cause early mortality, reduced reproductive success, or the occurrence of scorable DNA damage in individual fauna and flora to a level where they would have a negligible impact on conservation of species, maintenance of biodiversity, or the health and status of natural habitats or communities. To achieve these objectives, a set of reference dose models, reference dose per unit intake and reference organisms will be required

    Veterinary radiology is a tool of excellent diagnostic support. Besides X--ray, it counts on technological advances such as computed tomography, nuclear medicine and interventional radiology . It is common during X-ray practice to use exposure parameters with short times to avoid blurring by the movement of the animal, but the fact that the animals need to be immobilized during the exposures contribute significantly with the increase of the dose received by the professionals, whose biological risks are not yet well established as a result of exposure to other factors harmful to health, such as anesthetic gases, insecticides, zoonoses and others. For this reason, we sought to verify the main radiological risks to which veterinarians are exposed and the best means to guarantee radiological protection

    1992-01-01

    The Board was constituted as a public authority under the Radiological Protection Act 1970 with the functions of advancing the acquisition of knowledge about the protection of mankind from radiation hazards and providing information and advice to persons, including Government Departments, with responsibilities in the United Kingdom in relation to the protection from radiation hazards either of the community as a whole or particular sections of the community. The Board is also empowered to provide technical services to persons and groups of persons concerned with radiation hazards on a commercial basis. These accounts show that the surplus on ordinary activities amounted to 210k pounds; cash balances increased by 161k pounds to 748k pounds which includes 431k pounds held on behalf of European Partners under the CEC Association Agreement. The Board achieved the principal objectives which had been set out in the Corporate Plan. Demand for the provision of services and advice to industry and other public bodies continued at a constant level. Current major issues are the new Recommendations from the International Commission on Radiological Protection for control of exposure, and subsequent national recommendations on dose limitation; an increasing awareness of non-ionising radiation, and public exposures and aspects of radiation in the environment. In particular there has been a significant demand for radon surveys as part of a sponsored monitoring programme in the south-west which is largely responsible for the increase in income-earning activities. Further studies are being commissioned and it is likely, therefore, that the Board will continue to be involved in large-scale radon work in the immediate future. The financial objectives were attained with minor variances on the planned budget profiles. (UK)

  10. Training in radiological protection for nuclear programmes

    International Nuclear Information System (INIS)

    1975-01-01

    Many Member States are developing or already have developed their own national training programmes. The IAEA is actively involved in promoting training in radiological protection for nuclear programmes. The various types of training are fully discussed, with suggested curricula. An earlier report was published as Technical Reports Series No.31 in 1964. In 1973, new and additional information was received from Member States which is reflected in the present report. Training programmes are classified, according to those requiring training: specialists; persons whose work is closely related to radiological protection (administrators, public health officers and industrial health personnel, safety inspectors and engineers in nuclear installations, public service personnel); persons working with radiation; and the general public. Forms, scope and duration of training are discussed. Different types of training programmes are currently required for training of medical doctors (those providing medical surveillance for radiation workers and others dealing with public health aspects of radiation hazards), for technical supervisors, radiologists, and qualified workers in nuclear medicine, technological staff, administrators, persons working with radiation, and public service personnel. Standard curricula and desirable experiments and exercises are discussed. The organization of training together with the facilities, equipment and teaching staff required are considered, as is follow-up training. Annexes 1 to 4 give examples of training curricula and training courses available in various countries, a suggested syllabus for training of technical supervisors, and a bibliography consisting of 210 references dealing with general topics, nuclear radiation physics, radiochemistry and radiation chemistry, radiation biology and biophysics, dosimetry and health physics and radiation protection, medical aspects and toxicology, and environmental aspects

    In debates about nuclear controversy, the issue of occupational safety in radioactive facilities is rarely foregrounded; it has historically been relegated to second place compared to the attention given to potential harm to the general population. Aiming for, at least, partially filling this historiographical gap, this article deals with the development of occupational radiological protection in Spain under the dictatorship of General Franco (1939-1975). It covers the rise of radiological protection measures on an international level and the subsequent development of legislation in the case of Spain, a process that paralleled the growth of the nation's nuclear program. Finally, it explores the main evidence of the impact of ionizing radiation on Spain's working population.

    Full text of publication follows: The mission of the Nuclear Energy Agency (Nea) Committee on Radiation Protection and Public Health (C.R.P.P.H.) includes providing member -country governments with insight into evolving or emerging issues that could affect radiation protection policy, regulation or application. Although it can not be currently said that the scientific understanding of radiological risks has significantly changed recently, ongoing radio-biological and epidemiological research could challenge the conventional paradigm in the mid -term future. The C.R.P.P.H. finalized in March 2006 finalize a study of possible challenges and their implications. This study includes two principle areas: challenges arising from scientific developments; and, challenges to the implementation of radiation protection. This report updates the earlier C.R.P.P.H. report, 'Developments in Radiation Health Sciences and their Impact on Radiation Protection' (Nea 1998). Broadly speaking, ongoing radiation biology studies present the possibility that our current practice of summing various type s of exposures into a single value of effective dose is not scientifically supported because of significantly differing dose/response relationships (chronic vs. acute, internal vs. external, high Let versus low Let, etc.). In addition, non-targeted effects, and the possibility of individual hyper-sensitivity to radiation further challenge our current notion of the relationship between detriment and dose. Although there is no conclusive evidence for this at this time, the possible implications of such changes will be investigated to better prepare governments and the radiation protection community should sound scientific evidence emerge. In addition to these possible scientific challenges, the applications and events that would require radiological protection input are also evolving. In particular, the use of radiation in medicine, with new techniques and the spread of existing technologies

    In the world of diagnostic imaging, radiography is an important supplementary method for dental diagnosis. In radiology, special attention must be paid to the radiological protection of patients and health professionals, and also to image quality for correct diagnosis. In Brazil, the national rules governing the operation of medical and dental radiology were specified in 1998 by the National Sanitary Surveillance Agency, complemented in 2005 by the guide "Medical radiology: security and performance of equipment." In this study, quality control tests were performed in public clinics with dental X-ray equipment in the State of Sergipe, Brazil, with consideration of the physical parameters that influence radiological protection and also the quality of images taken in intra-oral radiography. The accuracy of the exposure time was considered acceptable for equipment with digital timers. Exposure times and focal-spot size variations can lead to increased entrance dose. Increased dose has also been associated with visual processing of radiographic film, which often requires repeating the radiographic examination.

    After a nuclear accident or radiological emergency, several social and economical factors shall be considered for the actions to protect the public and to recover the environment. The application of the radiological protection principles on practices in intervention situations may lead to adoption of protective measures disproportional to the involved risk, compromising the resources available to more effective actions. This causes a negative impact on the population and may conduct to discredit about the protective measures and the lost of confidence on the authorities. In this context, the principles of radiological protection for interventions should be studied and analyzed for being adequately applied in accident situations or radiological emergencies that involves the country. These principles are constantly improved and the concept of generic intervention level plays an important role in the decision-making to protect the public. The costs involved to the protective measures for the public in Brazil were studied and cost benefit analysis techniques were applied to estimate the generic intervention levels for public protection applicable in the country. These results were compared to those values internationally recommended, as well to values obtained in a similar study accomplished for Japan. It was also performed a sensibility analysis of the results regarding a value and a simple analysis of the results considering the costs of the several protective measures. (author)

    For radiological protection from exposure to ionizing radiation, in which a population-averaged dose evaluation is used, establishing a system of reference anatomical and physiological data for a specific population of interest is important. Some studies were done in the past to establish Korean reference data; however, the data provided the mass values only for a limited number of organs/tissues. In addition, the standing height and total body mass are based on 20-year-old data. In the present study, a new set of Korean reference anatomical values was established for use in the radiological protection of Korean workers and members of the public. The established Korean reference data provide the masses of 58 organs/tissues, including those needed to calculate the effective dose, which were derived by collecting and analyzing various scientific reports in the literature and data. In addition, the data provide not only standing height and total body mass, but also 131 additional anthropometric parameters; these values were derived from the most recent Korean national survey project, 7 th Size Korea. The characteristics of the data were also compared with several other population data, including the Asian and the International Commission on Radiological Protection (ICRP) reference data.

    For more than 40 years the UKAEA has been a world leader in the field of nuclear power R and D, pioneering the world's first civil nuclear programme and developing new nuclear power reactor technologies. Now that the initial programme has been successfully completed, UKAEA is again leading the world by pioneering new approaches to managing nuclear liabilities. In this new role, UKAEA is making a significant use of other companies in carrying out its decommissioning tasks and in providing support services. Whilst bringing with it new ideas and useful outside experience, this approach has given new challenges to UKAEA in ensuring that the work is carried out safety and that UKAEA is able to continue to exercise it's responsibilities as site operator and nuclear site licensee. This paper draws upon the experience within UKAEA to explore the management of radiological protection in a multi-employer situation emphasising the importance of co-operation between radiological protection experts, the need to clarify roles and responsibilities and the importance of worker participation. It is concluded that properly managed such an arrangement can not only work but can strengthen radiation protection building on various parties' strengths and experiences. One particular area where considerable use of service contractors has been undertaken is in radiological protection support services. UKAEA has now some unique experience in UK and have demonstrated that again, with adequate and appropriate management arrangements a potential challenge can be turned into an advantage. It is vital however that UKAEA is able to demonstrate sufficient in-house knowledge and expertise to remain in control as the site Licensee. (author)

    The optimization concept in radiation protection is, in its essence, practical. In each aspect that we deal with the man, it is necessary to take frequent decisions such as: what is the protection level to be pursued, since the protection levels under consideration provide doses lower than the appropriate annual limits. The optimization gives a basic framework of the minding that is appropriate to conduct to a balance kind of the resources available for the protection and protection level obtained against a multitude of factors and constrains in a manner to obtain the best result. In this work, was performed the optimization, from the radiation protection point of view, of a facility project who enclose two shielded hot cells where will be handled UO{sub 2} small plate with 50% of U-235 burn-up, irradiated in the research swimming pool reactor, IEA-R1. To obtain this goal were specified the relevant factors and criteria, were applied the main techniques used in a decision-making in radiological protection, presently adopted and was performed a sensibility study of the factors and criteria used in this work. In order to obtain a greater agility in applying the techniques for decision-making was developed a micro computer program. (author)

    Several U.S. universities maintain formal graduate health physics curricula within their Colleges of Engineering. The term radiological engineering was coined to describe the discipline of applying engineering principles to the radiation protection aspects of nuclear technology. Radiological engineering programmes may require a specific core group of courses such as radiation biology, radiation protection practice, nuclear physics, radiation detectors, and radiation dosimetry. Students then might specialist in environmental, nuclear facilities or medical applications areas by selecting advanced courses and graduate design or research projects. In some instances the master's degree may be completed through remotely-delivered lectures. Such programmes promise to assist in educating a new group of engineering professionals dedicated to the safe utilisation of nuclear technology. The Georgis Institute of Technology's programme will serve as the specific example for this report. 8 refs., 1 fig

    The China Society of Nuclear Medicine was established on 27 May 1980. Since then, nuclear medicine in clinical diagnosis and therapy has been developed rapidly in China. So far there are more than 4000 members of the Society, and more than 350 sets of SPECT and 12 sets of PET have been installed and are busily running in clinic nowadays and about 1 million patients with different types of diseases have obtained nuclear medicine imaging examinations per year. Concerning the nuclear medicine therapy, a lot of patients with many types of diseases obtained benefit from radioisotope therapy. Accordingly, several Policies and Regulations have been enacted by the Government for the radiological protection. Furthermore, a special book titled 'Standardization in Diagnostic and Therapeutic Nuclear Medicine' has been promulgated in June, 1997 by the Health Administration of People's Republic of China, and this book is distributed to almost every nuclear medicine physician and technician in China for their reference in routine nuclear medicine work or research. In this book three parts of the contents are covered: Policies and Regulations for the radiological protection, basic knowledge and clinical nuclear medicine applications. (author)

    2002-01-01

    The current system of radiological protection is aimed at protecting human health, and largely neglects both the effects of radiation on the environment and the managerial aspects of environmental protection. The Swedish Radiation Protection Act was revised in 1988 and includes environmental protection as one of its aims. In practice, little guidance had been given in the regulations based on the Act until 1998, when the Swedish Radiation Protection Authority (SSI) formulated environmental aims in its regulations concerning protection of human health and the environment in connection to the final management of spent nuclear fuel and waste. These regulations focus on protection of biodiversity and biological resources, based on ecosystem characterisation. In a broader perspective, the Swedish Parliament established 15 national environmental quality objectives in 1999, covering all aspects of protecting the environment, including the effects of radiation. This paper reviews the background for radiological protection of the environment from both an international and a Swedish perspective, describing the aims and current activities in establishing a system for assessing environmental effects and their consequences that can be used in decision-making. Such activities are largely a result of the European Union research project FASSET (Framework for Assessment of Environmental Impact), carried out under the 5th Framework Programme of the Union. This work is complemented at the Swedish national level by government support to initiate a national environmental monitoring and assessment programme for characterising the radiation environment, which will provide the foundation for decision-making.

    Full text: This lecture aims at presenting the state of the art of radiological protection of patients in nuclear medicine focusing on three aspects of interest where to achieve improvement. The hierarchy of the justification principle of the radiation protection is one of them. There seems for a change to be presented in the paradigm of the radiological protection of patients. The role of the physician who prescribes the medical practice becomes more relevant, together with the nuclear medicine specialist who should be co-responsible for the application of this justification principle. Regarding the doses optimization and the implementation of Dose Reference Level the involvement extends far beyond the physician and radioprotection officer. It is clear that the Medical Physicist is to play a very relevant role in the coordination of actions, as the nuclear medicine technician is to execute them. Another aspect to consider is patient specific dosimetry. It should become a routine practice through calculation of the absorbed dose based on biodistribution data. It should be assessed for each individual patient, as it depends on a number of patient-specific parameters, such as gender, size and the amount of fatty tissue in the body, as well as the extent and nature of the disease. In most cases, dosimetry calculations are not carried out and patients are administered standard levels of activity. There may be situations with a lack of knowledge on internal dosimetry as in many centers either none or only one or two medical physics experts are available. It shows that a formal training for experts in internal dosimetry at national level is required. However up to now, there has been no satisfactory correlation between absorbed dose estimates and patient response. Moreover, the radiation protection for the patient is not assured, as the dose values given are often numbers without connection to radiobiological and/or hematological findings. Pending tasks related to

    To evaluate radiation protection basic knowledge and dose assessment for radiological procedures among Italian radiographers A validated questionnaire was distributed to 780 participants with balanced demographic characteristics and geographic distribution. Only 12.1 % of participants attended radiation protection courses on a regular basis. Despite 90 % of radiographers stating to have sufficient awareness of radiation protection issues, most of them underestimated the radiation dose of almost all radiological procedures. About 5 % and 4 % of the participants, respectively, claimed that pelvis magnetic resonance imaging and abdominal ultrasound exposed patients to radiation. On the contrary, 7.0 % of the radiographers stated that mammography does not use ionising radiation. About half of participants believed that radiation-induced cancer is not dependent on age or gender and were not able to differentiate between deterministic and stochastic effects. Young radiographers (with less than 3 years of experience) showed a higher level of knowledge compared with the more experienced radiographers. There is a substantial need for radiographers to improve their awareness of radiation protection issues and their knowledge of radiological procedures. Specific actions such as regular training courses for both undergraduate and postgraduate students as well as for working radiographers must be considered in order to assure patient safety during radiological examinations. • Radiographers should improve their knowledge on radiation protection issues. • Only 12.1 % of participants attended radiation protection courses on a regular basis. • Specific actions must be considered in order to increase knowledge and awareness.

  8. International recommendations on scope of radiological protection regulations - ICRP Publication 104

    The system of radiological protection applies, in principle, to all exposures to ionising radiation. Nevertheless, in practice, the measures taken in order to control these exposures should be limited for pragmatic reasons. ICRP Publication 104 deals with the scope of radiological protection control measures and describes the instruments that can be used for this purpose: exclusion, exemption, clearance. This paper aims to present the ICRP recommendations on scope of regulations in all types of exposure situations: planned, emergency and existing. Also, there are discussed the instruments available to regulators in different exposure situations. Exclusion refers to the deliberate omission of exposure situations from the scope of regulatory requirements, and exemption refers to waiving regulatory requirements if their application is not warranted. A special case of exemption, termed 'clearance', refers to the relinquishing of regulatory control if such a control becomes unwarranted. Societal attitudes to the control of exposure situations are taken into account in determining what can be excluded or exempted from regulatory control. People have higher demands for controlling 'artificial' exposure situations than for dealing with 'natural' exposure situations. Therefore, account should be taken not only of the justification and optimisation of controlling measures, but also of the different expectations of those affected by the exposure situations. The recommendations in this report are intended to assist in defining what needs to be the subject of regulatory requirements for radiological protection and what does not. The application of regulatory controls should achieve a net benefit in protection; otherwise, regulatory control is not justified. Similarly, regulatory requirements should be applied in a manner that optimises protection, otherwise the application of regulatory requirements is not warranted. (authors)

    The Code of Practice and design principles for portable and transportable radiological protection systems are presented in three parts. Part 1 specifies the requirement for Radiological Protection Instrumentation (RPI) including operational characteristics and the effects of both a radiation and non-radiation environment. Part 2 satisfies the requirement for RPI equipment as regards the overall design, the availability, the reliability, the information display, the human factors, the power supplies, the manufacture and quality assurance, the testing and the cost. Part 3 deals with the supply, location and operation of the RPI equipment. (U.K.)

  11. Radiological protection issues in endovascular use of radiation sources

    International Nuclear Information System (INIS)

    2006-02-01

    The use of radiation from radioactive materials for cancer treatment is well established. However, examples of uses of radiation therapy for benign conditions have been limited. Placing a radioactive source in the blood vessel so as to irradiate the surrounding inner periphery of the vessel has been attempted in recent years to prevent restenosis after percutaneous coronary and peripheral interventions. This kind of endovascular application provides treatment options that are less invasive for various vascular conditions compared with open surgery. As a part of the International Atomic Energy Agency's (IAEA) function for providing for application of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS) that were jointly sponsored by the IAEA, FAO, ILO, OECD/NEA, PAHO and WHO, the IAEA planned a coordinated research project (CRP) that was to start in 2002 on radiological protection problems in endovascular use of radiation sources. However, as experts soon realized that the interest in this modality was waning, the CRP was not initiated. Nevertheless, it was felt that it would be appropriate to compile the information available on radiological protection problems observed so far and their possible solutions. This work was seen as part of a broader IAEA programme that covered accident prevention in radiotherapy. Publications on this topic have included, inter alia, Lessons Learned from Accidental Exposures in Radiotherapy (Safety Reports Series No. 17); Accidental Overexposure of Radiotherapy Patients in Bialystok; Investigation of an Accidental Exposure of Radiotherapy Patients in Panama; Accidental Overexposure of Radiotherapy Patients in San Jose, Costa Rica; and Investigation of an Accidental Exposure of Radiotherapy Patients in Poland. Keeping in mind that endovascular applications involve specialists such as cardiologists, angiologists and surgeons, all of whom might not have a

    These revised Recommendations for a System of Radiological Protection formally replace the Commission's previous, 1990, Recommendations; and update, consolidate, and develop the additional guidance on the control of exposure from radiation sources issued since 1990. Thus, the present Recommendations update the radiation and tissue weighting factors in the quantities equivalent and effective dose and update the radiation detriment, based on the latest available scientific information of the biology and physics of radiation exposure. They maintain the Commission's three fundamental principles of radiological protection, namely justification, optimisation, and the application of dose limits, clarifying how they apply to radiation sources delivering exposure and to individuals receiving exposure. The Recommendations evolve from the previous process-based protection approach using practices and interventions by moving to an approach based on the exposure situation. They recognise planned, emergency, and existing exposure situations, and apply the fundamental principles of justification and optimisation of protection to all of these situations. They maintain the Commission's current individual dose limits for effective dose and equivalent dose from all regulated sources in planned exposure situations. They reinforce the principle of optimisation of protection, which should be applicable in a similar way to all exposure situations, subject to the following restrictions on individual doses and risks; dose and risk constraints for planned exposure situations, and reference levels for emergency and existing exposure situations. The Recommendations also include an approach for developing a framework to demonstrate radiological protection of the environment

  18. The role of radiation protection in the rehabilitation of living conditions in contaminated territories after a nuclear accident or a radiological event

    Lochard, J.

    2006-01-01

    The implementation of radiation protection programmes in long -term contaminated territories is raising difficult technical, methodological, but also ethical questions, which commit the responsibility of the radiation protection professionals and the way they are exercising their expertise in such situation. The presence of contamination in the environment is a new reality which is profoundly affecting the living conditions of the population in all aspects: health, environment but also the psychological, social and economical cultural dimensions of daily life. In such a context, the classical radiation protection approach is inoperative to restore the normality of the ante accident situation On the contrary, the scientific and technological expertise and the prescriptive administrative arrangements, including the radiation protection ones, which are heavily mobilized to respond to the many challenges facing the society induce a progressive de -qualification of the environment and goods and a loss of control of the situation by the population which turn into a social depression. The paper illustrates how radiation protection programmes for managing long term contaminated territories have an ambivalent impact: on the one hand they ensure the protection of the population against the potential health impacts of radiations, on the other hand they re -enforce the loss of control, de-qualification and exclusion processes which results in a weakening of the resilience capacity of the population and the territories. The recent experience of co-expertise and co-operation implemented in the contaminated territories of Belarus have demonstrated that the direct engagement of local professionals and the population in the daily management of the radiological situation is not only feasible but also necessary to stop this vicious circle of loss of control and exclusion. To be effective and sustainable this engagement must rely on the diffusion among the population of a 'practical

    This report was prepared to underpin the Commission's 2007 Recommendations with regard to the medical exposure of patients, including their comforters and carers, and volunteers in biomedical research. It addresses the proper application of the fundamental principles (justification, optimisation of protection, and application of dose limits) of the Commission's 2007 Recommendations to these individuals. With regard to medical exposure of patients, it is not appropriate to apply dose limits or dose constraints, because such limits would often do more harm than good. Often, there are concurrent chronic, severe, or even life-threatening medical conditions that are more critical than the radiation exposure. The emphasis is then on justification of the medical procedures and on the optimisation of radiological protection. In diagnostic and interventional procedures, justification of procedures (for a defined purpose and for an individual patient), and management of the patient dose commensurate with the medical task, are the appropriate mechanisms to avoid unnecessary or unproductive radiation exposure. Equipment features that facilitate patient dose management, and diagnostic reference levels derived at the appropriate national, regional, or local level, are likely to be the most effective approaches. In radiation therapy, the avoidance of accidents is a predominant issue. With regard to comforters and carers, and volunteers in biomedical research, dose constraints are appropriate. Over the last decade, the Commission has published a number of documents that provided detailed advice related to radiological protection and safety in the medical applications of ionising radiation. Each of the publications addressed a specific topic defined by the type of radiation source and the medical discipline in which the source is applied, and was written with the intent of communicating directly with the relevant medical practitioners and supporting medical staff.

    Full text: With the evolution of the norms of radiological protection in the world in last the 20 years, the life expectancy of Workers increased in direct ratio. The technological advance of the equipment that uses radiation sources and the deepening in the studies and knowledge on the ionizing radiations- e consequent deleterious effect- had contributed significantly for the reduction of the doses received for the Workers in its daily hours of working. Methods: A simple analysis of data, comparing itself the past and the gift, becomes evident that, in if treating to radiological protection, the humanity walks for a new age, which hardly will retrocede. If before the radiological protection was understood as a concern only in the practical doctors, with emphasis in the immediate effects, today already becomes gift in all the practical ones, especially in that they put into motion the planet and its wealth, in the industry. Major Values: Modernity took the man to the daily dependence of the not ionizing radiations, each time inserted of the people's day. As similar to, the radiological protection today if makes gift in diverse practical, to guarantee the cares to be taken and the fulfilment of pertinent norms. The present study it looks for to evidence that last the 20 years- marked for accidents with radioactive sources- they had been essential for a reflection of the norms of radiological protection. Thus, workers, as well as the technological sector, changed it the new reality, either demanding bigger training technician for the practical ones, attention special in security and radiological protection, or same establishing more rigid norms, through the regulating agencies. In the present work had a projection of values of life expectancy of the population, the past until the present. Analyzing Tables, as much for workers how much for the members of the public is noticed that the radiological protection offers to one better quality of life to all those involved

    This qualitative research with workers of seven hemodynamic service of Santa Catarina, Brazil aimed to analyze the use of radiological protection equipment (RPE), as well as wear to the health of workers who use these causes. The study was conducted between March 2010 and November 2010, totaling approximately 30 hours of observations. Results showed resistance to the use of RPE and also showed wear to workers' health, mainly due to the weight and discomfort they cause, as may weigh 7-9 pounds, depending on the model used. Evidenced also the absence of workers due herniated disc, back pain, and other musculo skeletal problems. These complaints, in addition to being related to the use of these protective gear also related with the time that workers remain standing for long periods on certain procedures, such as angioplasty. Given these results, the research recommended the use of these devices with materials, that are already being produced, making lighter aprons, thus avoiding fatigue and back pain and also provide greater comfort by reducing workers' resistance to its use and its adverse consequences

    Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

    The Pain Clinic of the CIMEQ offers treatment to patients with different pathologies, using interventional techniques as the radiology like visual guide to reach the target structure and to apply the election technique. The personnel that carry out these procedures are inserted in the program of radiological surveillance of the institution, reason for which a radiological event could be detected where the main physician responsible of the service was implied. In this work the results of an investigation are presented realized with the objective of to know the causes of the event and to determine the necessary measures to avoid that this repeats again. The investigation was oriented to three fundamental aspects: medical exam of the affected worker; evaluation of the operational procedures from the radiological protection view point; and dosimetric measurements simulating the real conditions of work for which were used ionization chamber, radiometer and PMMA mannequin. As a result of the medical exam was detected that the main physician of the service did not use during the execution of all the procedures the extremities dosimetry and that he presented a radio induced erythema in the right hand, reason for which he was separated of the activity with ionizing radiations, until the conclusion of the investigation. With relationship to the evaluation of the operational procedures from the radiological protection view point, was verified that the medical physician not carried out any collimation of the beam and he was located in the positions where the dose rate reached the maximum values, frequently introducing the hands in the direct beam; that which implied an overexposure of the superior extremities and a not optimized exposure for whole body. This result was proven with the realized experimental measurements, which gave dose estimated values in extremities of the order of the deterministic effects. The investigation facilitated to introduce modifications in the

    We consider as initial radiological protection paradigms those in vigour after the release of the atomic energy for pacific usages in 1955. In that occasion, only one paradigm was introduced, presently named dose limitation system. After arguing about the basis that raised the paradigm, we introduced the guidance, that is, the measurements to be implemented to comply with the paradigm. In that occasion, they were two, i.e., the radiation dose monitoring and the workplace classification. Afterwards, the reasons that caused the radiological protection paradigms changes in force until 1995 are discussed. The initial paradigm was modified introducing the justification and the optimization principles, adding that the radiological protection should be economical and effective. The guidance also increased to four: personal monitoring, workplace classification, reference level and workers classification. Afterwards, we give the main justifications for the present paradigms that besides the formers were added the dose constraints, the potential exposure and the annual risk limits. Due to these modifications, the workers classifications were eliminated from the guidance, but the potential exposure and the search for the dose constraints were added. Eventually, we discuss the tendencies for the next future and the main changes introduced by the ICRP in the Publication 103, 2007. (author)

  6. Application of radiological protection measures to meet different environmental protection criteria

    2012-01-01

    The International Commission on Radiological Protection (ICRP) recognises that there is no simple or single universal definition of ‘environmental protection’, and that the concept differs from country to country and from one circumstance to another. However, there is an increasing need to be able to demonstrate that the environment is protected from radioactive substances released under authorisation for various reasons, such as for wildlife conservation requirements, or wildlife management for commercial reasons, or simply as part of pollution control. The Commission is developing the concept of Representative Organisms, which may be identified from any specific legal requirements or from more general requirements to protect local habitats or ecosystems. Such organisms may be the actual objects of protection or they may be hypothetical, depending on the objectives of the assessment. They may be similar to, or even congruent with, one or more of the Reference Animals and Plants (RAPs). Where this is not the case, attempts can be made to consider the extent to which the Representative Organisms differ from the nearest RAP in terms of known radiation effects upon it, basic biology, radiation dosimetry, and pathways of exposure. This paper discusses the practical implications of such an approach.

    For some years there has been comprehensive guidance documentation for Nuclear Reactor Instrumentation, but apparently no corresponding guide for designers and installers of Radiological Protection Instrumentation. A small group of instrumentation engineers discussed this lack of a suitable guide, and they examined the main points on which it should be based. This document attempts to present a comprehensive and detailed review of these points. It is intended to give an overall coverage and serve as a reference document for specific points; it should also be of value to the newcomer to the Radiological Protection Instrumentation field. This Code of Practice represents a standard of good practice and takes the form of recommendations only. Each installation must be assessed individually, and agreement on its suitability must be reached locally by the designers and the officers responsible for safety and operation. (author)

  9. Principles of the International Commission on Radiological Protection system of dose limitation

    International Nuclear Information System (INIS)

    Thorne, M.C.

    1987-01-01

    The formulation of a quantitative system of dose limitation based on ICRP principles of 'stochastic' and 'non-stochastic' effects requires that judgements be made on several factors including: relationships between radiation dose and the induction of deleterious effects for a variety of endpoints and radiation types; acceptable levels of risk for radiation workers and members of the public; and methods of assessing whether the cost of introducing protective measures is justified by the reduction in radiation detriment which they will provide. In the case of patients deliberately exposed to ionising radiations, the objectives of radiation protection differ somewhat from those applying to radiation workers and members of the public. For patients, risks and benefits relate to the same person and upper limits on acceptable risks may differ grossly from those appropriate to normal individuals. For these reasons, and because of its historical relationship with the International Congress of Radiology, the ICRP has given special consideration to radiation protection in medicine and has published reports on protection of the patient in diagnostic radiology and in radiation therapy.

It establishes, in the first place, the system of dose limits for the country and the principles of its utilization. It takes into account the CIPR's recommendations in this area and the mentioned frame of reference, it establishes further the necessary restrictions for the application of the limits to the professionally exposed workers, as well as to the isolated members of the public and the population in general. In addition it establishes the general conditions to be met for the implementation of radiological protection, among them, the classification of working areas and working conditions as well as the compulsory periodical medical surveillance.

    All the people that work with ionizing radiations should have a singular license according to that settled down in the effective legal standards in force in Peru. This authorization is granted by the Peruvian Institute of Nuclear Energy (IPEN) after the postulant demonstrates that he can work in sure form in the application where it uses ionizing radiations. From 1972 the Superior Center of Nuclear Studies (CSEN) of the IPEN it has carried out diverse training courses on radiological safety and protection in medicine, industry and research, such it is so until the year 2005 it has organized 458 courses where 5872 people have been qualified in the country. 75% of people was qualified in the period 2000 - 2005. The courses are organized according to the specific work with radiations and in the one case of medical radiodiagnostic, dental radiology, nuclear medicine and radiotherapy has been qualified 2337 people (doctors, medical technicians and technicians) by means of 174 courses made among the years 2000 at the 2005, corresponding 69,75% to people qualified in radiological protection in medical radiodiagnostic.

Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

    The report of International Commission on Radiological Protection (ICRP) Task Group 80 entitled 'Radiological protection in geological disposal of long-lived solid radioactive waste' updates and consolidates previous ICRP recommendations related to solid waste disposal (ICRP Publications 46, 77, and 81). The recommendations given in this report apply specifically to geological disposal of long-lived solid radioactive waste. The report explains how the 2007 system of radiological protection, described in ICRP Publication 103, can be applied in the context of the geological disposal of long-lived solid radioactive waste. The report is written as a self-standing document. It describes the different stages in the lifetime of a geological disposal facility, and addresses the application of relevant radiological protection principles for each stage depending on the various exposure situations that can be encountered. In particular, the crucial factor that influences application of the protection system over the different phases in the lifetime of a disposal facility is the level of oversight that is present. The level of oversight affects the capability to reduce or avoid exposures. Three main time frames have to be considered for the purpose of radiological protection: time of direct oversight when the disposal facility is being implemented and active oversight is taking place; time of indirect oversight when the disposal facility is sealed and indirect oversight is being exercised to provide additional assurance on behalf of the population; and time of no oversight when oversight is no longer exercised because memory is lost.

    This is the third in a series of reports prepared by the-National Advisory Committee on Radiation for the Surgeon General of the Public Health Service. The first two were directed to the broad responsibilities of the Service in the field of radiation control and to problems concerned with the protection of the public against undue radiation exposure from contamination of the environment with radioactive materials. In this report the Committee traces the remarkable growth that has taken place in the uses of ionizing radiation in the health professions, in industry, and in other walks of life. It also notes a number of emerging problems which not only are of importance from the point of view of radiation protection, but also, if not alleviated, threaten the quality of medical care in the United States and the translation of the advances of atomic research into needed benefits for the people. These problems include (a) serious weaknesses in academic departments of radiology which have restricted efforts to provide adequate instruction of medical and post-doctoral students in the clinical applications of ionizing radiation, including radiation protection; and (b) an increasingly severe shortage of manpower in all branches of the radiological sciences. The magnitude and complexity of these problems are sufficiently great that a concerted effort is needed by the Public Health Service to correct them. The alleviation of the problems just cited is but a part of a more comprehensive series of responsibilities faced by the Service in the radiological sciences. The Service must play an important role in the prevention of undue exposure of the population from medical, occupational, and environmental sources of ionizing radiation; at the same time, it must actively support the development and application of radiological methods in the diagnosis and treatment of diseases. In order that the Service may effectively meet its enlarging responsibilities in the radiological sciences

    The interaction between the health and the radiological protection areas has proved fundamental, in our work experience, for the quality of response to victims of accidents, involving ionizing radiation. The conceptions and basic needs comprehension of the adequate response, on these two areas, have brought changes to the essential behavior related to the victim's care, the protection response, the environment and waste production. The joint task of health professionals and radiological protection staff, as first responders, demonstrates that it is possible to adjust practices and procedures. The training of professionals of the radiological protection area by health workers, has qualified them on the basic notions of pre-hospital attendance, entitling the immediate response to the victim prior to the health team arrival, as well as the discussion on the basic concepts of radiological protection with the health professionals, along with the understanding of the health area with its specific needs on the quick response to imminent death risk, or even the necessary procedures of decontamination.

    2010-09-01

    The nuclear medicine practice dates of the 1950 years, in this work the achievements reached as regards radiological protection are shown, although even lack a lot to make, the doses for the occupationally exposed personnel have decreased with lapsing of the years, thanks to the perception of the nuclear physicians to improve the administration techniques of the radioactive material, the decrease of administered activity and the unit doses use among the most remarkable advances. The changes in the equipment s technology to quantify the activity to administer, detection systems and image formation have demanded the development of the new professionals of the nuclear medicine that allows give protection to the patient. This improvement needs to consolidate with the appropriate normative development, the involved personnel qualification and the methods and procedures actualization to improve the protection of the occupationally exposed personnel, the public, the environment and the patient.

    The comparison of doctrines concerning protection against ionizing and non-ionizing radiation is a difficult task, because of the many areas in which it is applied. Radiological pollution has grown during the century, but its evolution has not been concomitant. This has resulted in a distortion that can be identified in the successive steps of the evaluation and protection against such radiation. For a better understanding, this discussion deals with the differences in interaction with matter and the induction of the related risks, on the varieties of protection systems and monitoring procedures

    It can be defined radiation protection culture as the set of technical and social standards applied to the management of the operation of a nuclear facility concerning the reduction of the exposure to radiation of workers and members of the public, together with the behaviour and attitudes of the individuals from the organization towards that objective. Because the basic principles of radiation protection are self-evident and are totally justified, and the thesis drawn from the article is that no effective radiation protection culture yet exists within the organization, it must be concluded that what is wrong from the system are the attitudes and behavior of the individuals. In this article some factors and elements needed to motivate all persons within the organization towards the creation of a radiation protection culture are delineated and presented. (Author)

    The program of operative radiological protection of a nuclear power plant consists of multiple procedures and associate tasks that have as purpose the radiological protection of the workers of the power station. It is for this reason that the constant evaluation of the one it programs it is an important tool in the identification of their weaknesses (and strengths), so they can be assisted appropriately. In this work the main elements of the program of independent auto evaluation of the program of operative radiological protection of the Laguna Verde Central that has been developed and implemented by the National Institute of Nuclear Research are described.

    The companies that are working in decontamination, dismantling and assessment in nuclear power plants, usually have their employees in different facilities far from its central offices. When there is a training in radiological protection applied to the nuclear field, it is difficult for these people the attendance to the course because of different reasons as the location of the formation centres which sometimes are not near from the nuclear facilities, so they usually cannot attend their daily work with the same effectiveness. In this work we present a postgraduate training in radiological protection supervised by Polytechnical University of Valencia (Spain) applied to nuclear and radioactive facilities by a technological platform developed in collaboration with the university. This platform is adapted and designed to different high level contents and applications in different areas and sections, related to a general part, radioactive facilities, nuclear facilities and advanced concepts. When the student finishes an area, an evaluation has to be done to prove the understanding of the lessons. We have included films of different activities as decontamination devices, radiation detectors..etc with the contents to make the explanations more understandable to the student. The course is complemented with a final review and exam that are not online to guarantee that the training is well finished. In addition the student has some practice related with different items explained during the training as the use of equipment in radiological protection tasks. This type of training is more flexitime and can be adapted to the necessities of each user, avoiding high costs and unnecessary displacements. (author)

    2006-01-01

    This report compiles the various numerical protection level values published by the International Commission on Radiological Protection (ICRP) since its 1990 Recommendations (Publication 60). Several terms are used to denominate the protection levels: individual dose limit, 'maximum' individual dose, dose constraint, exemption level, exclusion level, action level, or intervention level. The reasons provided by the Commission for selecting the associated numerical values is quoted as far as available. In some cases the rationale is not totally explicit in the original ICRP report concerned; in such cases the Task Group that prepared the present report have proposed their own interpretation. Originally, this report was prepared by a Task Group at CEPN, a French research and development center, in behalf of IRSN, a French public expert body engaged in radiological protection and nuclear safety. It is published here with kind permission by CEPN and IRSN.

    The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document 'Education and

    The present work is first one in this gener that it is made in the Department of the Freedom - Peru. The intention was to do a diagnose of the radiation protection in the sanitary scope taking into account some main parameters like the level of qualification of the worker occupational exposed, the design of environment and the quality of the equipment in aspects like: collimation, filtration, kV and time. In this study were taken into account the Hospitals of the Department of the Freedom that belong to the Ministry of Health, Social Security and Private Centers of Health. From each hospital a random sample of the radiology worker was taken and it was applied a survey with related questions to radiological safety. The gather of the information became by means of direct survey. The obtained results are very useful, because besides to make a real diagnose of the radiation protection, evaluating the human and technical factor, they serve to improve the aspects of quality in radiological diagnosis, since the conclusions allow to establish if it is counted on a suitable level of radiation protection on the part of the workers and if the equipment fulfills the quality necessary to reach an efficient use of x-rays

    The European Union has established specific directives concerning radiological protection which are obligatory for member States. In addition, all Spanish dental clinics with radiological equipment are required to have an annual quality control check. To analyze the effect of new European legislation on dental radiological practice in Spain and to determine whether it has resulted in lower doses being administered to patients. A total of 10,171 official radiological quality control reports on Spanish dental clinics, covering 16 autonomous regions, were studied following the passing of Royal Decree 2071/1995 on quality criteria in radiodiagnostic installations. The reports, compiled by U.T.P.R Asigma S.A., a company authorised by the Nuclear Safety Council, cover the years 1996 to 2003, which has enabled us to monitor the evolution of radiological procedures in dental clinics over a seven year period. According to the reports for 2003, 77.3 % of clinics complied with EU requirements, using equipment of 70 kVp, 8 mA, 1.5 mm Al filters, with a collimator length of 20 cm. However, non-compliance was detected in approximately a third (30.8%) of the equipment inspected: alterations in the kilovoltage used, exposure time, performance of the tubing, dosage, linearity/intensity of current and acoustic-luminous signal 6.86%. The mean skin dose reached 3.11 mGy for patients who received an x-ray of an upper molar, representing a decrease of 18% over the seven years studied. there has obviously been a general improvement in the parameters studied, but only 77.3% of the installations complied fully with official EU regulations concerning dental radiological protection.

    Full text: Development of radiological protection of non-human biota continues to be the focus of much interest and differing views amongst the radiological protection community. To nurture discussion of these developments, the Nuclear Energy Agency's Committee on Radiological Protection and Public Health is taking the lead in organising coverage of a spectrum of views on the topic at the International Conference on Radioecology and Radioactivity in the Environment (Bergen, 2008), with the aim of assisting the international community to construct a consensual, fit-for-purpose approach. To support discussion of these views, the session will also include scientific presentations and reports from implementers. This paper will report on these developments, based principally on the session at the Conference but also other activities in which NEA participates, to provide an up-to-date summary in this area including progress in developing understanding of how radiological protection of the environment will be implemented for the three exposure situations - planned, existing and emergency - set out in the new ICRP general recommendations. Furthermore, given the NEA's mandate across the civil nuclear energy field, the paper will give a commentary on how developments in radiological protection of the environment may interplay with new build of nuclear power plants.

    1993-01-01

    The state of teaching Radiation Protection in Medical School in Italy was considered. An historical approach was utilized, in order to define periods of time characterized by different conditions. Some data are collected by a concise enquiry on the information given during the course of Radiology in the second triennial cycle, and on some other teaching courses including information on radiation effects. The conclusion is that teaching times are exceedingly reduced, and the need of improving the diffusion of knowledge in the field is stressed. An official Act of the OECD and of European Community is expected, with the aim of emphasizing the importance of the information of doctors on Radiation Protection as a problem of public interest. A proposal is advanced of implementing the Teaching of Radiobiology in the second triennial cycle, changing the name of the course in 'Radiobiology and Radiological Protection'. 6 tabs

    The application of ionizing radiation in medicine seems to be a safe procedure for patients as well as for occupational exposition to personnel. The developments in interventional radiology with fluoroscopy and dose-intensive interventions require intensified radiation protection. It is recommended that all available tools should be used for this purpose. Besides the options for instruments, x-ray protection at the intervention table must be intensively practiced with lead aprons and mounted lead glass. A special focus on eye protection to prevent cataracts is also recommended. The development of cataracts might no longer be deterministic, as confirmed by new data; therefore, the International Commission on Radiological Protection (ICRP) has lowered the threshold dose value for eyes from 150 mSv/year to 20 mSv/year. Measurements show that the new values can be achieved by applying all X-ray protection measures plus lead-containing eyeglasses. (orig.) [German] Die Anwendung ionisierender Strahlung in der Medizin scheint sowohl fuer Patienten als auch fuer beruflich exponierte Personen sicher zu sein. Die interventionellen Entwicklungen der letzten Jahre mit sehr durchleuchtungs- und dosisintensiven Eingriffen erfordern allerdings eine Intensivierung des Strahlenschutzes. Es empfiehlt sich, die zur Verfuegung stehenden Moeglichkeiten auszuschoepfen. Neben den Geraeteoptionen muss der Strahlenschutz am Eingriffstisch durch Bleilamellenaufstecker und montiertes Bleiglas intensiv betrieben werden. Besonderen Fokus muss auf den Schutz der Augen zur Kataraktvermeidung gelegt werden. Da dessen Ausbildung nach neuen Erkenntnissen moeglicherweise nicht mehr deterministisch zu sehen ist, hat die Internationale Strahlenschutzkommission (IRCP) den Grenzwert von 150 auf 20 Mikrosievert (mSv)/Jahr erniedrigt. Messungen belegen, dass unter Einhaltung aller Strahlenschutzmassnahmen plus Bleiglasbrille dieser einzuhalten ist. (orig.)

    The quality assurance in diagnostic radiology in Mexico before 1997 was virtually nonexistent except in few academic institutions and hospitals. The purpose of this study was to carry out an exploratory survey of the issue of quality control parameters of general and fluoroscopy x-ray systems in the Mexican Republic and their effects in the quality image and radiological protection of the patient. A general result of the survey is that there is not significant difference in the observed frequencies among public and private radiology departments for α = 0.05, then the results are valid for both departments. 37% of x-ray systems belong to public radiology departments. In the radiology departments that didn't agree with the Mexican regulations in: light field to mach the x-ray field, light field intensity, kV, time and output. In those cases, we found a repeat rate of radiography studies >30% with non necessary dose to patient, low quality image and high operating costs of the radiology service. We found in x-ray fluoroscopy systems that 62% had a low quality image due to electronic noise in the television chain. In general the x-ray systems that didn't agree with Mexican regulations are 35% and they can affect in a way or other the quality image and the dose to patient

    This work aims to verify the actual conditions for the training of technicians in Radiology, in relation to the knowledge of radiation protection in the field of Medical Diagnostic Radiology. To evaluate the knowledge of professionals was prepared a questionnaire on the topic, having been answered by workers with varied experience. The questionnaire was divided into three parts, being the initial self-evaluation, followed by closed and open issues, all specific knowledge. With a total of 55 questionnaires answered, it was found that 85% of respondents consider themselves able to work in the area performing the function, but when questioned about the technical details regarding the exposure to ionizing radiation, it was found that only 15% of respondents had some knowledge about the subject. In relation to Radiological Protection, was found that little more than 10% of the respondents know about the subject. The results found in this survey outlined the creation of a technical specialization course in radiation protection, which is part of the permanent staff of course of the Polytechnical School of Health of FIOCRUZ, solving, partially, one of the problems pointed out today by health bodies, that is the lack of trained personnel

    Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

    Kun-Woo Cho gave a panorama of the 1. Asian Workshop held in Daejeon on 27-28 August 2013 and he focused mainly on the results of the discussions carried out within the three Working Groups. In each group the discussion initially addressed on two questions: What issues of radiation protection refer to ethics? What are the ethical values (explicit and implicit), which underlie the system of radiological protection? WG 1 focused on the fact that the RP system includes judgments that refer to ethical values, but they are implicitly and un-clearly presented in the ICRP recommendations; on the dialogues about the foundation, objectives and rationality of RP system, which should be pushed to facilitate the understanding of the system for RP specialists and stakeholders; and on RP culture and wise behaviours vis-a-vis radiation, which should be promoted in the society. WG 2 discussed the need of ethical consideration in the system of radiological protection; the need to revisit whether individual rights to happiness or justice had been respected; the need to provide more rationales to support important judgments in the RP system, and the need to refine the term 'members of the public' to distinguish informed individuals with certain benefit in return. WG 3 noted that strong parallels between bio-ethics and RP ethics exist. It has also agreed that simplicity, education and communication efforts are required in the RP system to overcome public misunderstanding and to enhance acceptability. With respect to the values of RP ethics attention was given to tolerance of people's views, human dignity, justice, respect for persons, beneficence, prudence, understanding/simplicity and well-being. The presentation reported a view of the conclusions obtained from the 1. Asian Workshop focused on communication, well-being, tolerability and acceptability of risk as the main issues addressed

    This paper presents a way to use the ICRP approach for protection of the environment in generic assessments of the radiological impact of radioactive releases to the marine environment. Generic assessments of radiological impact to the environment are needed in certain circumstances, for example, when input data are limited or when the likely radiological consequences are expected to be not significant. Under these circumstances the effort in performing the assessment must be commensurate with the potential radiological consequences. The generic assessment described in this paper is a simple tool which provides reasonable and cautious results and is applicable to multiple exposure scenarios associated with the assessment of the radiological impact of releases to the marine the environment. This generic assessment can be also used to provide preliminary results which, when compared to radiological criteria, may determine the need of further specific assessments. The ICRP based its approach to protect the environment in the definition of a set of reference animals and plants and the use of related radiological criteria, in the form of derived consideration reference levels. The paper discusses selection and exposure conditions of the reference animals and plants, methods to estimate their doses and the use of the radiological criteria, for the purpose of a generic assessment. The IAEA is elaborating applications of these generic impact assessments presented in the paper to be included in international guidance under development. (authors)

    Since the International Commission on Radiological Protection (ICRP) initiated a dialogue in 1999 on the evolution of the system of radiological protection, the NEA Committee on Radiation Protection and Public Health (CRPPH) has actively engaged in providing the ICRP with input and views. The Committee's work on this subject has included eight expert group reports, seven international conferences, and four detailed review and comment assessments of draft ICRP recommendations. This report presents a chronological summary of the issues, views and concerns raised by the CRPPH as the ICRP issued various draft versions of its new recommendations (ICRP Publication 103, published in December 2007), and of the response by the ICRP as seen in its subsequent draft recommendations. The interest of this summary report is that it will not only assist readers in understanding the main themes and concepts of the new ICRP recommendations, but also why and how the changes from the previous ICRP Publication 60 recommendations came about.

    Purpose: Previously, the diagnostic radiological index of protection (DRIP) was proposed as a metric for quantifying the protective value of radioprotective garments. The DRIP is a weighted sum of the percent transmissions of different radiation beams through a garment. Ideally, the beams would represent the anticipated stray radiation encountered during clinical use. However, it is impractical to expect a medical physicist to possess the equipment necessary to accurately measure transmission of scattered radiation. Therefore, as a proof of concept, the authors tested a method that applied the DRIP to clinical practice. Methods: Primary beam qualities used in interventional cardiology and radiology were observed and catalogued. Based on the observed range of beam qualities, five representative clinical primary beam qualities, specified by kV and added filtration, were selected for this evaluation. Monte Carlo simulations were performed using these primary beams as source definitions to generate scattered spectra from the clinical primary beams. Using numerical optimization, ideal scatter mimicking primary beams, specified by kV and added aluminum filtration, were matched to the scattered spectra according to half- and quarter-value layers and spectral shape. To within reasonable approximation, these theoretical scatter-mimicking primary beams were reproduced experimentally in laboratory x ray beams and used to measure transmission through pure lead and protective garments. For this proof of concept, the DRIP for pure lead and the garments was calculated by assigning equal weighting to percent transmission measurements for each of the five beams. Finally, the areal density of lead and garments was measured for consideration alongside the DRIP to assess the protective value of each material for a given weight. Results: The authors identified ideal scatter mimicking primary beams that matched scattered spectra to within 0.01 mm for half- and quarter-value layers in

    Full text: The Laboratory of Internal Dosimetry (LDI) of the Nuclear Energy Peruvian Institute (IPEN) is the laboratory which offers the service of internal dosimetry to the IPEN personnel who works handling non sealed radioactive sources. The Laboratory has participated in several intercomparison exercises featuring in vivo measurements, in vitro methods and dose calculations with acceptable results, which are indicators that the laboratory results are reliable. The National Program of Radiological Protection for occupational exposed workers, who handles non sealed radioactive sources, allows involving the IPEN occupational exposed workers and the Nuclear Medicine Centres Personnel. In Peru, there are 5000 occupational exposed workers, 3500 of them are controlled through external dosimetry. There are approximately 230 occupational exposed workers to non sealed radioactive sources, 67 of them are registered in the National Regulatory Authority and 20 are controlled radiologically. The aim of this study is the enhancement of the radiological safety of the personnel who works in the Nuclear Medicine Centres and handles non sealed radioactive sources. As part of this work, activities addressed to improve the radiological safety of the occupational exposed workers were taken place such as: supply of technical documents about radiological safety, performance of surveys and polls and the organization of a workshop involving the participation of several health professionals working in this field. The situation of the control measures in the radiation protection of the patients and occupational exposed workers, based in updated regulatory documents, have been assessed and it allowed knowing and learning that the occupational exposed workers of the Nuclear Medicine Centres could perform their own monitoring program since they have potential capabilities like Iodine Uptake Systems and calibrated Gamma cameras. This study involves 15 public and private institutions. (author)

    The nuclear accidents in the world are very few among various types of operating facilities. However when an accident happened, we have learnt a lot to improve the philosophy, term, definitions, document preparation, equipment's requirement, supporting systems, awareness program and restriction etc. After Fukushima Dai-ichi we have learnt a lot, in this view this paper has been prepared to discuss for radiological protection aspects. Discussion: The probability of nuclear accidents is negligible but when happens, it opens new doors of lessons for radiological protection practices for occupational workers, emergency workers for damage control to prevent catastrophic situation/rescue to life saving actions and the member of the public. The Chernobyl and Three Mile Island accidents have provided a lot experiences for management of emergency situations, documentation, radiation emergency preparedness, emergency equipment's, concept of defense-in-depth, emergency planning zone (EPZ), accidental dose limits, estimation of source term and public dose, intervention levels, decision supporting system, remedial actions in public domain; decontamination of person, houses/building and land and etc. Recent Fukushima Dai-ichi accident in Japan was managed in appreciable manner but still new definitions and lessons for radiological protection have been emerged out. The present paper discusses difficulties w. r. t. the radiological aspects observed/faced by Japanese during nuclear crises. The accident introduced new terms as Natural Dose Rate Unit (NDRU), voluntary evacuation, deliberate evacuation area, restricted area and difference between evacuation zone and EPZ. The Fukushima accident has enforced worldwide regulators and operators to review the individual dose limit and amendment for raise in the dose limit during accident, availability of efficient/adequate quantities of personal dosimeter in public domain, collection arrangement of bulk amount of radioactive wastes

    The general standards of radiological protection found in 23 veterinary practices are summarised, with reference to the recommendations of the Code of Practice for the Protection of Persons Exposed to Ionising Radiations from Veterinary Uses. The views expressed by the veterinary surgeons interviewed are included where relevant. It is concluded that the majority of practices do not completely satisfy the present standards for radiological safety but that the radiographic workloads are small and unlikely to give cause for alarm. Of most concern are the doses to the hands and forearms of persons who manually restrain small animals during radiography. Recommendations are made concerning the need for greater management supervision in practices and the training and designation of veterinary workers. The veterinary profession are urged to promote discussion on radiological procedures and techniques which avoid the exposure of the personnel involved. (author)

  6. Problems with radiation protection concerning volunteers accompanying radiological patients

    Full text: The purpose of this work is to point out, within the framework of the Radiation Protection guidelines, the irregular situation of the 'volunteer' or 'accompanying person' who accompanies anyone requiring medical treatment with ionising radiation, as well as to suggest a possible justification for such role. It should be noted that most of these persons are subject to ionising radiation without knowing anything about the effects that it could cause on them, so that their condition could be hardly considered as 'voluntary'. There are several circumstances under which the presence of accompanying persons is required, being different among them. Several examples could be mentioned such as: those who are accompanying a direct relative (family bonds), those who are acting in service during their normal work (social workers, policemen) and even those who are forced by unusual under an accidental situation. The qualitative classification that radiological protection established in society concerning radiation risks for people in general enables to set mechanisms of justification, optimisation and dose limitation for each category, being perfectly identified which of them each person belongs to. But the figure of 'accompanying person' has been excluded from such characterisation. They are subject to radiation exposure without knowing it, or without having any information concerning the potential risks. For them, no balance between the net benefit of an adequate medical treatment versus potential health detriment may be applied as for the case of a patient. Thus, their exposure could be not justified. It is not the purpose of this work to question radiological medicine or its practices, but to clarify certain aspects involving members of the public in general, patients and members of the radiological community, as well as to propose lines of action concerning this subject. We conclude that it is not the volunteer who should decide about medical actions, a role

    This paper studies 278 official reports on quality assurance in dental radiology in the context of the first revision of these dental clinics, as a result of the entry into force of the regulations establishing the duties for these types of facilities. In the results section we present a quantitative analysis of the facilities equipped with an panoramic radiology apparatus, making a special reference to the brands they have available, as well as their physical features (kV, mA, filtration) and the deviations detected in their operation. Some of their features in the process of obtaining radiological images at those facilities (film control, development time, liquid renewal) are determined, and the average dose of ionising radiation used in order to obtain the same tooth radiological image is presented. This paper shows, in a quantitative way, the characteristic features of panoramic radiology in our medium. The study is intended to be continued during the next years, which would allow the assessment of the prospective improvement in dental radiological performances as a result of the newly established regulations.

    Practical and philosophical aspects of radiation protection in diagnostic radiology have changed very little over the past 50 y even though patient doses have continued to rise significantly in this period. This rise has been driven by technological developments, such as multi-slice computed tomography, that have been able to improve diagnostic accuracy but not necessarily provide the same level of risk-benefit to all patients or groups of patients given the dose levels involved. Can practical radiation protection strategies hope to keep abreast of these ongoing developments? A project was started in 1992 in Liverpool that aimed to develop IT driven quality assurance (QA)/radiation protection software tools based upon a modular quality assurance dose data system.

    Practical and philosophical aspects of radiation protection in diagnostic radiology have changed very little over the past 50 y even though patient doses have continued to rise significantly in this period. This rise has been driven by technological developments, such as multi-slice computed tomography, that have been able to improve diagnostic accuracy but not necessarily provide the same level of risk-benefit to all patients or groups of patients given the dose levels involved. Can practical radiation protection strategies hope to keep abreast of these ongoing developments?

    An evident purpose of the radiological protection training is to use suitable protective equipment and to behave correctly if unexpected working conditions happen. A major difficulty of this training consist in having the most realistic reading from the monitoring devices for a given exposure situation, but without using real radioactive sources. A new approach is developed at EDF R/D for radiological protection training. This approach combines different technologies, in an environment representative of the workplace but geographically separated from the nuclear power plant: a training area representative of a workplace, a Man Machine Interface used by the trainer to define the source configuration and the training scenario, a geo-localization system, fictive radiation monitoring devices and a particle transport code able to calculate in real time the dose map due to the virtual sources. In a first approach, our real-time particles transport code, called Moderato, used only an attenuation low in straight line. To improve the realism further, we would like to switch a code based on the Monte Carlo transport of particles like Geant 4 or MCNPX instead of Moderato. The aim of our study is the evaluation of the code in our application, in particular, the possibility to keep a real time response of our architecture. (authors)

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

    The serious study of high-energy particle accelerator radiological protection began in the early 1950s and has continued since then. This paper treats the subject in seven stages, and begins by briefly reviewing the work done until the 80s, which comprises the first five stages. These are, observation of high radiation levels, shielding studies, dosimetry, induced activity and the environmental effects. The sixth stage, control by legislation and regulation, is discussed in detail. Over the past twenty years there have been significant additions to radiological protection standards: from a scientifically based estimate of risk to a social desire to reduce exposure to levels determined only by the ''best practical means (BPM)'' or as it is currently understood in the United States of America ''best available technology (BAT)''. The implications of this trend are explored, and the success with which changing standards have been followed is studied with the aid of data derived from personnel doses. The last stage is the decommissioning or disposal of high energy accelerators. (author)

  15. Radiological protection, safety and security issues in the industrial and medical applications of radiation sources

    2015-01-01

    The use of radiation sources, namely radioactive sealed or unsealed sources and particle accelerators and beams is ubiquitous in the industrial and medical applications of ionizing radiation. Besides radiological protection of the workers, members of the public and patients in routine situations, the use of radiation sources involves several aspects associated to the mitigation of radiological or nuclear accidents and associated emergency situations. On the other hand, during the last decade security issues became burning issues due to the potential malevolent uses of radioactive sources for the perpetration of terrorist acts using RDD (Radiological Dispersal Devices), RED (Radiation Exposure Devices) or IND (Improvised Nuclear Devices). A stringent set of international legally and non-legally binding instruments, regulations, conventions and treaties regulate nowadays the use of radioactive sources. In this paper, a review of the radiological protection issues associated to the use of radiation sources in the industrial and medical applications of ionizing radiation is performed. The associated radiation safety issues and the prevention and mitigation of incidents and accidents are discussed. A comprehensive discussion of the security issues associated to the global use of radiation sources for the aforementioned applications and the inherent radiation detection requirements will be presented. Scientific, technical, legal, ethical, socio-economic issues are put forward and discussed. - Highlights: • The hazards associated to the use of radioactive sources must be taken into account. • Security issues are of paramount importance in the use of radioactive sources. • Radiation sources can be used to perpetrate terrorist acts (RDDs, INDs, REDs). • DSRS and orphan sources trigger radiological protection, safety and security concerns. • Regulatory control, from cradle to grave, of radioactive sources is mandatory.

  16. The social and cultural construction of radiological risk: a case study

    Man, society or culture, considered as objects, cannot be measured in the same way as one would measure gravity or a hyperbola. In these conditions, how can one isolate the socio-anthropological aspects from the overall perception of radiological risks, thus the nuclear question? This paper deals with an empirical study derived from some fundamental research conducted in order to explain how different social actors conceive the nuclear question by means of different social construction of reality. It fits into the sociological scheme of knowledge posing a set of methodological and theoretical questions that have as the object the study of the social determinants of knowledge related to the nuclear question. The present survey, carried out in Belgian agricultural workers, makes clear how such determinants interact to form one social construction of the radiological risk. It allows us to presume that the perception of the radiological risks cannot be reduced to some laypeople's measurable psychic (mis)perceptions. (author)

  17. Main radiation protection actions for medical personnel as primary responders front of an event with radiological dispersive device

    After the terrorist attack in New York, USA, in 2001, there was a worldwide concern about possible attacks using radioactive material in conventional detonators, called as Radiological Dispersal Device (RDD) or 'dirty bomb'. Several studies have been and are being made to form a global knowledge about this type of event. As until now, fortunately, there has not been an event with RDD, the Goiania Radiological Accident in Brazil, 1987, is used as a reference for decision-making. Several teams with technical experts should act in an event with RDD, but the medical staffs who respond quickly to the event must be properly protected from the harmful effects of radiation. Based on the radiological protection experts performance during the Goiania accident and the knowledge from lessons learned of many radiological accidents worldwide, this work presents an adaptation of the radiation protection actions for an event with RDD that helps a medical team as primary responders. The following aspects are presented: the problem of radioactive contamination from the explosion of the device in underground environment, the actions of the first responders and evaluation of health radiation effects. This work was based on specialized articles and papers about radiological accidents and RDD; as well as personal communication and academic information of the Institute of Radiation Protection and Dosimetry. The radiation protection actions, adapted to a terrorist attack event with RDD, have as a scenario a subway station in the capital. The main results are: the use of the basic radiation protection principle of time because there is no condition to take care of a patient keeping distance or using a shielding; the use of full appropriate protection cloths for contaminating materials ensuring the physical safety of professionals, and the medical team monitoring at the end of a medical procedure, checking for surface contamination. The main conclusion is that all medical actions

    it is notorious that one of the main causes of radiological accidents is the lack of knowledge of radiological protection of workers. In order to meet the needs of professionals in acquiring a solid base in radiological protection and safety, was created in 2013, by the Casa Branca School / SP and technically supported by the company MAXIM Cursos, the 'Post-Graduation Course Lato Sensu de Radiological Protection in Medical, Industrial and Nuclear Applications', which offers a broad improvement in radiation protection. The course of 380 hours and duration of 18 months is divided into 13 modules, including theoretical classes, in person and online using the virtual classroom and practical training in radiation protection in general. In the end students should present a monograph, guided by a course teacher and reviewed by an Examining Bank. Five classes have been formed in these four years, totaling 92 students. In all, 51 monographs have been defended on topics of technical and scientific interest. For this, the Faculty consists of 25 professors, being 9 Doctors, 13 Masters and 3 Specialists in Radiological Protection.

    This study, carried out at the radiometallurgy laboratory of the Fontenay-aux-Roses Nuclear Research Centre, is based on an ergonomic approach. It shows that the shielded chamber control station, designed for human protection against ionizing radiations, demands an effort of adaptation on the part of the operator. This station does in fact meet radiological protection obligations but would benefit from certain improvements aimed at reducing the secondary fatigue of manipulators already under the strain of adapting to the machine. Fields in which improvements and/or changes are desirable have been investigated with special reference to telemanipulators. New and better designed instruments will soon appear on the telemanipulator market [fr

    The Angra 1 Nuclear Power Plant (NPP) is a Westinghouse two-loop plant with net output before its 1P16 Outage of 632 MWe, with the Old Steam Generators (OSG) type model D3, which were replaced by two new Steam Generators with feed water-ring system. Localized in Angra dos Reis, Rio de Janeiro - Brazil, Angra 1 started in commercial operation in 1985 and, from the beginning problems related to corrosion have appeared in the Inconel 600 alloy of the tubes. The corrosion problems indicated the necessity for a strong control of the tubes thicknesses and, after a time, the ELETRONUCLEAR decided to replace the OSG. In 2009, ELETRONUCLEAR initiated in January 24, the actions for the Steam Generators Replacement - SGR. During the SGR process, several controls were applied in field, which made possible to have no radiological accidents, no dose limits exceeded, and permitted to achieve a very good result in terms of Collective Dose. This paper describes the radiological controls applied for the Angra 1 Steam Generator Replacement Outage, the radiological protection team sizing and distribution and the obtained results. (author)

    The Nuclear Energy Agency's (NEA's) Committee on Radiological Protection and Public Health (CRPPH) has collaborated closely with the ICRP in its efforts to develop new recommendations for radiological protection at the start of the 21st century. As part of this effort, the NEA organised, in collaboration with the ICRP, two fora to discuss the radiological protection of the environment (Taormina, February 2002) and the future policy for radiological protection (Lanzarote, April 2003). Both these meetings were attended by a broad representation of stakeholders. The CRPPH and other stakeholders universally appreciated the opportunity to speak directly with the ICRP on these important subjects. This report summarises the main conclusions made during these two meetings to advance the deliberations of the ICRP to create a new set of recommendations responsive to stakeholder needs, firmly rooted in science, and that can be implemented in a timely, efficient and cost-effective manner.

    Full Text Available Radiological protection of the environment has been intensively discussed in recent years. Much progress has been made recently with regard to the development of models: (i to estimate the uptake of radionuclides by flora and fauna in different habitats and ecosystems; (ii to calculate internal and external exposures for a wide range of terrestrial and aquatic organisms; and (iii in investigating and analyzing the effects of radiation exposures to biota. This paper gives an overview of the current status of this work. Furthermore, the current status of the integration of environmental protection into the radiation protection system is also summarized.

  7. The development of an environmental protection programme for the population based on concepts and standards inspired by radiological protection

    1977-01-01

    Following the United Nations Conference in Stockholm, 1972, on the protection of the environment a certain number of principles and methods have been put forward to national authorities which put into effect environmental protection programmes. Several of these principles have been taken directly from and inspired by the field of application of radiological protection; it is not without interest to draw comparisons between those which have been conceived and applied in health physics for the prevention of a radioactivity risk as it applies to the population, and those which already exist or which are envisaged vis-a-vis the risks from non radioactive pollutants. It is opportune to remember that the ICRP publications, in particular those published in and after 1958, included recommendations on radiological protection, and that these recommendations laid down the bases for both the theoretical steps and the practical methodology of which the main components are still in existence today; a remarkable achievement which merits emphasis. The ICRP recommendations included in publication 1 and more particularly publications 7, 9 and 22 introduced the basic concepts of a health physics policy which can be recognized as having been beneficial for the protection of man and his environment and which can be utilized as a basis for consideration, if not action, as it concerns the non-radioactive environmental pollutants [fr

    2000-01-01

    This statutory instrument provides for the implementation of Council Directive 96/29/Euratom of 13 May 1996 laying down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionising radiation. It also incorporates the provisions of Council Directive 90/641/Euratom of 4 December 1990 on the operational protection of outside workers exposed to the risk of ionising radiation during their activities in controlled areas. It replaces the provisions of the European Communities (Ionising Radiation) Regulations, 1991 (S.I. No. 43 of 1991), the Radiological Protection Act, 1991 (General Control of Radioactive Substances, Nuclear Devices and Irradiating Apparatus) Order, 1993 (S.I. No. 151 of 1993) and the European Communities (Protection of Outside Workers from Ionising Radiation) Regulations, 1994 (S.I. No. 144 of 1994). The main changes introduced in this Order are: the inclusion of work activities involving exposure to natural sources of radiation, stricter application of existing radiation protection principles through the introduction of lower dose limits, the use of dose constraints in keeping doses as low as reasonably achievable (i.e. optimisation process) and extended application of justification principles, the introduction of radiation protection principles for intervention in cases of radiological emergencies or lasting exposures.

    Due to increasing cardiac disease and its mortality rate, the frequency of cardiac imaging has grown and, as a result, interventional cardiologists potentially receive high radiation doses in cardiac examinations. This study aimed to assess the knowledge, attitude, and practice (KAP) level of radiation protection (RP) among interventional radiology staff in Iranian health care centers across the country. We used a validated questionnaire survey consisting of 30 multiple-choice questions to perform a cross-sectional study. Participants were healthcare personnel working professionally with radiation at different levels (i.e., secretary, radiology technologists, nurse, and physician). The questionnaire was divided into three sections to assess KAP regarding RP. Significant differences exist in RP KAP mean scores based on educational age (p 0.050). We found a significant difference between RP KAP mean scores and different regions (p < 0.050). Educational and practice age, sex, type of hospital, and geographical region affect he KAP of interventional radiology staff regarding RP. Since many of the subjective radiation harms for both medical team and patients, this can be easily controlled and prevented; a checkup for personnel of interventional radiology departments, considering samples from different parts of the country with different levels of education, continuous training, and practical courses may help map the status of KAP. The results of this study may also help authorized health physics officers design strategic plans to enhance the quality of such services in radiation departments.

    In the UK, as elsewhere, there is potential to improve how radiological challenges are addressed through improvement in, or development of, a strong radiation protection (RP) safety culture. In preliminary work in the UK, two areas have been identified as having a strong influence on UK society: the healthcare and nuclear industry sectors. Each has specific challenges, but with many overlapping common factors. Other sectors will benefit from further consideration.In order to make meaningful comparisons between these two principal sectors, this paper is primarily concerned with cultural aspects of RP in the working environment and occupational exposures rather than patient doses.The healthcare sector delivers a large collective dose to patients each year, particularly for diagnostic purposes, which continues to increase. Although patient dose is not the focus, it must be recognised that collective patient dose is inevitably linked to collective occupational exposure, especially in interventional procedures.The nuclear industry faces major challenges as work moves from operations to decommissioning on many sites. This involves restarting work in the plants responsible for the much higher radiation doses of the 1960/70s, but also performing tasks that are considerably more difficult and hazardous than those original performed in these plants.Factors which influence RP safety culture in the workplace are examined, and proposals are considered for a series of actions that may lead to an improvement in RP culture with an associated reduction in dose in many work areas. These actions include methods to improve knowledge and awareness of radiation safety, plus ways to influence management and colleagues in the workplace. The exchange of knowledge about safety culture between the nuclear industry and medical areas may act to develop RP culture in both sectors, and have a wider impact in other sectors where exposures to ionising radiations can occur.

This involves restarting work in the plants responsible for the much higher radiation doses of the 1960/70s, but also performing tasks that are considerably more difficult and hazardous than those original performed in these plants. Factors which influence RP safety culture in the workplace are examined, and proposals are considered for a series of actions that may lead to an improvement in RP culture with an associated reduction in dose in many work areas. These actions include methods to improve knowledge and awareness of radiation safety, plus ways to influence management and colleagues in the workplace. The exchange of knowledge about safety culture between the nuclear industry and medical areas may act to develop RP culture in both sectors, and have a wider impact in other sectors where exposures to ionising radiations can occur.

    The regulation antecedents in nuclear question in Mexico are placed in 1950, with the promulgation of {sup L}aw that declares national mining reserves the uranium deposits, thorium and the other substances of which obtains fissionable isotopes that can produce nuclear energy{sup ,} instrument that stipulated the control of uranium, thorium, as to its it indicated it name, and other fissionable substances, on the part of the state, although they were without a doubt the respective institutions, the National Commission of Nuclear Energy in 1955, and the one of the National Commission of Nuclear Safety and Safeguards (CNSNS) in 1979, those that allowed the development of a prescribed frame in the nuclear and radiological areas. One characteristic of the regulation in radiological protection is the variety in the authorities type that have incidence in the regulation, as a result of the different approaches with which it can be approached. For example, in Mexico normative instruments with content in radiological protection exist and are watched over the Health Secretary, who is oriented to the protection of the patient, their relatives and the medical body; Work and Social Welfare Secretary, with a labor approach; Communications and Transport Secretary, which regulates the transport of nuclear and radioactive materials; Finance and Public Credit Secretary, who regulates the import and export of radioactive materials; Environment and Natural Resources Secretary, which regulates the environment protection; Energy Secretary who has responsibilities inside of the {sup p}rescribed law of article 27 constitutional in nuclear matter{sup ;} and within the energy sector, the CNSNS that expedite and watch the fulfillment of normative in radiological protection and nuclear safety. In order to resist effects of on regulation; frequently inter institutional agreements are carried out in which the areas of monitoring are agreed by each authority. The regulation in radiological

    Today in day is difficult to imagine the development of the medical practices in the diagnosis and treatment of diverse illnesses without the use of the ionizing radiations. In spite of the diffusion and application of these practices, the patients and the public in general don't have full conscience of like the procedures are carried out and the risks that these involve. For it diverse international and national organizations in the last years recommend to include in the programs of radiological protection, all the information that should be given to the patients and the one public that attend as users to the medical institutions to undergo to procedures that imply the use of the ionizing radiations. In Cuba a growing and quick tendency exists to the introduction of nuclear techniques for medical ends, however paradoxically the relative aspects to the communication to the patients and the public in general about the risks of the procedures to that they will be subjected and in consequence on the measures to minimize them is not adequate. Keeping in mind the above-mentioned, specialists of national centers linked to the control and consultant ship in the topics of radiological protection in the medical practices that use ionizing radiations, they worked in the country in the design of an information system that should contribute to elevate the population's culture before the mentioned aspects. The present work describes the structure of this system in function of the different medical attention levels of our national health system. Additionally it exposes the development of a package of varied informative and training tools among those that are folding, posters, guides, instructions, CD Show that its approach general and specific aspects of the uses and risks of medical practices in nuclear medicine, radiodiagnostic and radiotherapy directed so much to health professionals, patients as public in general.

    Mammography is an effective method used for breast diagnostics and screening. The aim of this project is to review the literature on how to establish radiation protection programme for mammography in order to protect the patients, the occupationally exposed workers and the members of the public from harmful effects of ionizing radiation. It reviews some of the trends in mammography doses and dosimetric principles such as average glandular dose in the glandular tissue which is used for description of radiation risk, also the factors affecting patient doses are discussed. However, the average glandular dose should not be used directly to estimate the radiation risk from mammography. Risk is calculated under certain assumptions from determined entrance surface air kerma. Given the increase in population dose, emphasis is placed on the justification and optimization of the mammographic procedures. Protection is optimized by the radiation dose being appropriate with the purpose of the mammographic examination. The need to establish diagnostic reference levels as an optimization is also discussed. In order to obtain high quality mammograms at low dose to the breast, it is necessary to use the correct equipment and perform periodic quality control tests on mammography equipment. It is noted that in order to achieve the goal of this project, the application of radiation protection should begin at the time of requesting for mammography examination, positioning of the patient, irradiation, image processing and interpretation of mammogram. It is recommended that close cooperation between radiology technologists, radiologist, medical physicists, regulatory authority and other support workers be required and established to obtain a consistent and effective level of radiation protection in a mammography facility.

    Intervention levels for protection of the public in a radiological emergency are theoretically derived by the cost-benefit approach with the concept of justification and optimization. Intervention levels on the sheltering, evacuation, temporary relocation and permanent resettlement for protection of the public are estimated with the cost to protective countermeasures and the value from dose averted which are the site specific parameters. As a result, it is confirmed that IAEA guidelines for intervention levels are applicable to the radiological emergency in Korea. Optimum ranges of 5 - 10 mSv/2days for sheltering, 25 - 130 mSv/week for evacuation, 15 - 90 mSv/month for temporary relocation and 600 - 3,500 mSv/lifetime for permanent resettlement for intervention levels are also provided. The result can be applied as useful data to update intervention levels under the theoretical background in Korea

    After getting independence 2006 year and became 192nd member of UN, Montenegro state is conducting measures for radiation protection autonomously. Because of complexity of such issues, Montenegro faced a lot of problems: lack of a national legal system in this field, expertise, appropriate equipments etc. Some estimates have shown that the major exposures of populations in Montenegro to ionizing radiation are due to the medical care. The purpose of this work is to analyze current protection in radiological diagnostics in Montenegro and compare it with international standards. It could be clearly stated where they are in agreement or disagreement. The method of analyzing is a holistic one, starting from the law, regulations and decisions through the protocols of quality controls and finishing with the reports and database of important parameters and data. The main findings are stated as follows: although the current radiation protection in radiological diagnostics is conducting according the law of former Federal Republic of Yugoslavia (FRY) and its regulations and decisions, the overall legal system is still satisfactory; Identification and location of radiation sources through a system of notification and maintaining a national inventory is not satisfactory; There are a lack of expertise and equipments for the technical services, although the procedures and protocols of the quality control are at a satisfactory level; There is a lack of knowledge of professional staff working in this field. The practice is sometimes operated carelessly; The patients protection is satisfactory but there is not care to decrease a level of exposure according the ALARA principle. (author)

    A review of the role and relevance of the principles of radiation protection of the patient in diagnostic radiology as specified by ICRP has been undertaken when diagnostic risks arising from an examination are taken into account. The increase in population doses arising from diagnostic radiology over the past 20 years has been due to the widespread application of higher dose CT examinations that provide significantly more clinical information. Consequently, diagnostic risks as well as radiation risks need to be considered within the patient radiation protection framework. Justification and optimisation are discussed and the limitations imposed on patient protection by employing only a radiation risk framework is highlighted. The example of radiation protection of the patient in breast screening programmes employing mammography is used to highlight the importance of defined diagnostic outcomes in any effective radiation protection strategy.

    Testing plays an important role in deciding whether products which irradiate the general public are acceptable from a radiological protection point of view. This report discusses the role which testing should play in decision-making and develops a systematic approach to the testing of products. As an example of this approach, a proposed test programme for ionisation chamber smoke detectors is described. The use of test results as a basis for design specifications and performance requirements in the development of radiological protection standards for products is discussed. A description of the relevant standards is included. (author)

    The Nuclear Energy Agency's (NEA's) Committee on Radiological Protection and Public Health (CRPPH) has collaborated closely with the ICRP in its efforts to develop new recommendations for radiological protection at the start of the 21st century. As part of this effort, the NEA organised, in collaboration with the ICRP, two fora to discuss the radiological protection of the environment (Taormina, February 2002) and the future policy for radiological protection (Lanzarote, April 2003). Both these meetings were attended by a broad representation of stakeholders. The CRPPH and other stakeholders universally appreciated the opportunity to speak directly with the ICRP on these important subjects. This report summarises the main conclusions made during these two meetings to advance the deliberations of the ICRP to create a new set of recommendations responsive to stakeholder needs, firmly rooted in science, and that can be implemented in a timely, efficient and cost-effective manner.

    In order to identify radiation protection current situation in national X-ray diagnostic practice , the State (cuban) Supervision System for Radiation and Nuclear Safety carried out in 1992 a survey which was planned for projection of future regulatory activities in this field. Survey covers the most important aspects related to radiation protection of occupationally exposed workers, patients and general population. Surveyed sample included a total of 52 X-ray units, sited in 7 dental clinics, 2 polyclinics and 13 hospitals, from 7 provinces of the country. Results showed that the organization of radiation protection in terms of personnel specially designated to carry out surveillance and control activities and level of documentation is deficient. Survey evidenced the general lack of safety and quality culture among technologists and radiologists which is mainly reflected in non regular application of basic patient protection measures (shielding, collimation, use of proper filtration among others) and non regular execution of basic quality inspection of employed radiographic systems.

    The need for a definitive basis for radiological guidelines and criteria for FUSRAP became apparent by 1981 and led ORO to sponsor a joint ANL/BNI/LANL/ORO effort under the chairmanship of Wayne Hansen (LANL) that resulted in a final FUSRAP radiological guidelines document in March 1983. A separate effort to develop guidelines for remedial action criteria for SFMP was in progress at PNL. The need to coordinate both efforts with impending revisions of DOE Radiological Protection Standards and impending new developments in EPA and NRC Radiological Protection Standards led to convening of the first DOE Workshop on Remedial Action Criteria in Gaithersburg, Maryland, in February 1984, followed by a second workshop in June 1984 at ANL. The major decisions were to base the criteria on dosimetry models and basic limits currently recommended by the International Commission on Radiological Protection, to emphasize the development and use of site-specific rather than generic guidelines and criteria for residual radionuclide concentrations in the ground, and to prepare a manual to accompany the guidelines that would present procedures and tables for deriving site-specific soil guidelines and criteria for the remedial action programs. A joint ANL/LANL/ORNL/PNL effort to prepare a definitive set of guidelines and a manual has been initiated. The scope, status, and current plans for this effort, and some of the key issues, are presented. 10 references, 1 table

    The biological effects of radiation and potential risks therefrom far exceeds the knowledge of any other hazardous agent, whether in the industrial field, or in the general environment affecting members of the public. The International Commission on Radiological Protection (ICRP) has been playing a pioneering role for decades in this direction. The extensive database that has been established over the decades by the ICRP, the methodologies, techniques and the organizational structures that have been developed to control radiation hazards, and, above all, the philosophy of risk evaluation and management that has been evolved by ICRP, would serve as valuable guides not only to those concerned with radiological protection but to scientist, technologist and administrators involved in all facets of occupational and industrial safety, as well as those concerned with environmental protection. From 1959 to the end of 1993 ICRP has brought out 64 publications running to around 9000 pages. It is important that everyone connected with the uses of ionizing radiations should be familiar with at least the basic features of the thinking of ICRP as embodied in these publications. The present handbook attempts to give in a concise, consolidated and codified form the salient features of all the relevant information contained in the voluminous ICRP publications. The material has been presented in 7 parts, each dealing with one major aspect of the recommendations, and summarizing the various publications connected with it. A separate note following the preface gives a brief summary of the way the contents of the handbook have been arranged. refs., tabs., figs

    The protection of children during a radiological emergency is a potential concern that clearly transcends national boundaries and is therefore international in scope. Careful planning is needed to prevent independent actions on the part of school officials and parents that, although well intended, may lead to increased risks from radiation exposure, from traffic accidents, or from panic behavior. As part of its overall support for off-site emergency preparedness program, the Commonwealth Edison Company (CECo) has recently expanded the scope of planning for the protection of students in schools near its Quad Cities Nuclear Power Station in Cordova, Illinois. Working with off-site officials and with the assistance of emergency planners from Impell Corp., CECo has developed standard operating procedures (SOPs) to direct the emergency response activities for school administrators. These SOPs establish the chain of command for implementing protective actions and list alternative precautionary actions for a range of site conditions. In addition, during the development of these SOPs, CECo has had to address the following issues: interagency cooperation and consistency in approach; resource identification for transport, reception, registration, and communication; internal school procedures; and emergency preparedness training and exercising

    On the basis of concrete results obtained in the CEA's uranium mines over a period of 15 years, the authors determine to what extent the costs of radiological protection affect the price of uranium. The principles on which radiological protection is organized in the CEA mines are mentioned. Emphasis is placed on the precautions which have to be taken in order to ensure that radioactivity measurements are representative despite the extreme complexity and the variability of conditions in the workings. A description is given of the way in which the operation of the ventilation system is varied on the basis of radioactivity measurements as the workings are extended. The authors conclude that in the CEA mines, where the uranium content in the ores frequently exceeds one per cent, it is possible to ensure that the current standard is actually adhered to and that nevertheless the cost of radiological protection remains marginal. In the second part of the paper the possible effects of increasing the stringency of the standards are examined. The considerations are based on several thousands of measurements carried out in various workings and galleries. It is shown that the correlation between radon concentration and ore content is weak. It is pointed out that the state of equilibrium of radon daughters in the workings is of the order of 0.2 rather than the 0.5 assumed in the standard. On this basis the mean level of actual exposure, in total alpha energy, is of the order of 20% of the value 1.3 x 10 5 MeV α/litre, the level of the most highly exposed worker being 80% of that value. In addition, it is shown that with simple improvements to the design of the ventilation circuits and elementary precautions it is often possible to ''rejuvenate'' the radon in the workings and influence still further the state of equilibrium of the daughters. Finally, preliminary results obtained in the experimental mine at La Crouzille indicate that the radon concentration can be further

    Professionals in radiology suffer whole body exposure to low doses for long periods . The system of radiological protection should keep exposures below recommended thresholds, thus avoiding the stochastic effects that can be triggered with any dose level value, and there is not a threshold for induction of the same. Therefore it is important to use personal dosimeter for monitoring doses and protective equipment. The increase in procedures using ionizing radiation in recent years has been noted with concern, since many companies are not complying with the standards of protection. This is because some procedures may be performed without the need of surgery, which presents a greater risk to the patient. Furthermore, Brazilians are being exposed to radiation without necessity. The reasons range from radiological equipment miscalibrated to poorly trained staff. Thus we evaluate the conditions and practices of radiation protection technicians in radiology according to Ordinance 453 in Goiania, GO, Brazil. Through a descriptive survey with a quantitative approach, we used the technique of gathering information based on a questionnaire. From this survey, we identified the procedures used by radiation protection professionals and concluded that there are failures in the procedures for protecting patients and accompanying and in the training of the professionals.

    Hubbard, L.; Mjones, L.; Holm, E.

    2004-01-01

    In 1999, the Swedish Parliament adopted fifteen environmental quality objectives, defining the quality of Sweden's environment and of its natural and cultural resources that will insure sustainable growth. In 2001, the government proposed interim targets for each objective, specifying the direction and time scale of the proposed actions. These objectives give Sweden a unique opportunity to define, quantify and achieve an ecologically sustainable environment. One of the national objectives, A Safe Radiation Environment, targets both ionising and non-ionising radiation and states, human health and biological diversity must be protected against the harmful effects of radiation in the environment. The Swedish Radiation Protection Authority (SSI) has the responsibility for formulating and achieving the interim targets for this objective. The targets presently focus on controlling radioactive emissions, limiting exposures to ultraviolet radiation and defining the risks from exposure to electromagnetic fields. Part of SSI's responsibility for the environmental quality objective is to develop a system for monitoring and quantifying progress towards each interim target. Sweden's National Board of Housing, Building and Planning (NBHBP) is responsible for another of the national objectives, A Good Built- Environment. As part of this objective, a special interim target for the indoor environment was approved by Parliament in 2002, which includes a specification for human exposure to radon in indoor air. It states: radon concentrations should be lower than 200 Bq/m3 in schools and pre-schools by the year 2010, and below 200 Bq/m3 in homes by 2020. This substantially raises the level of ambition regarding reducing exposure to indoor radon. The aim of this paper is to briefly summarize the role of radiological protection in Sweden's environmental quality objectives. (Author) 3 refs

    Highlights: • New kind of radiological protection concept is introduced. • The shielding concept is accompanied with the water spray system. • The solubility of radioactive material could be used for protection. • Practical method is suggested. • The system is variable by the random number quantities. - Abstract: The environmental defense system in the nuclear power plants (NPPs) is investigated in the aspect of the environmental scale incorporated with atmospheric and marine sectors. The object is to find the radiological protection protocol in the environmental scale which is different from the conventional three kinds of radiological protection principles. Conventional laboratory based principles are not applicable in the mass failure accident such as the case of Fukushima disaster. This newly introduced protocol has many useful applications for the nature treatment oriented methods where the atmospheric protection of dispersion and dissolution is performed first and the filtration of seawater would follow. The maximum and minimum values in fan velocity are about 7.5 m/s and 5.3 m/s respectively. For the spray system, the mole fractions by the water spray are shown where maximum and minimum values are 6.57 × 10 −17 and 8.84 × 10 −19 moles respectively. The maximum and minimum values of discharged values in filtration are 99.4 and 1.3 square velocity (m/s), respectively. The total and general radiological protection concept is suggested in the nanoscopic molecular scale performance.

In addition to these straightforward measures derived from the lessons learned, a more comprehensive approach should include review and optimization of technical factors used in protocols, such as the use of high-dose-rate modes, of magnification, of high image frequency, of extremely extended fluoroscopy time and exploratory research of the potential for dose reference levels as a tool for optimization. The IAEA, together with the European Commission, the World Health Organization and the Pan American Health Organization has prepared a report which provides practical measures of radiation protection in interventional radiology. This report reviews the use of interventional radiology, the observed deterministic effects, the methods for dose monitoring to patients and staff and the parameters influencing image quality and radiation dose. Finally, the document provides recommendations on syllabus for training programmes of the different professionals involved. (author)

    The use of radiation sources, namely radioactive sealed or unsealed sources and particle accelerators and beams is ubiquitous in the industrial and medical applications of ionizing radiation. Besides radiological protection of the workers, members of the public and patients in routine situations, the use of radiation sources involves several aspects associated to the mitigation of radiological or nuclear accidents and associated emergency situations. On the other hand, during the last decade security issues became burning issues due to the potential malevolent uses of radioactive sources for the perpetration of terrorist acts using RDD (Radiological Dispersal Devices), RED (Radiation Exposure Devices) or IND (Improvised Nuclear Devices). A stringent set of international legally and non-legally binding instruments, regulations, conventions and treaties regulate nowadays the use of radioactive sources. In this paper, a review of the radiological protection issues associated to the use of radiation sources in the industrial and medical applications of ionizing radiation is performed. The associated radiation safety issues and the prevention and mitigation of incidents and accidents are discussed. A comprehensive discussion of the security issues associated to the global use of radiation sources for the aforementioned applications and the inherent radiation detection requirements will be presented. Scientific, technical, legal, ethical, socio-economic issues are put forward and discussed.

    The use of technologies to provide security screening for individuals and objects has been increasing rapidly, in keeping with the significant increase in security concerns worldwide. Within the spectrum of technologies, the use of ionizing radiation to provide backscatter and transmission screening capabilities has also increased. The Commission has previously made a number of statements related to the general topic of deliberate exposures of individuals in non-medical settings. This report provides advice on how the radiological protection principles recommended by the Commission should be applied within the context of security screening. More specifically, the principles of justification, optimisation of protection, and dose limitation for planned exposure situations are directly applicable to the use of ionising radiation in security screening. In addition, several specific topics are considered in this report, including the situation in which individuals may be exposed because they are concealed (‘stowaways’) in a cargo container or conveyance that may be subject to screening. The Commission continues to recommend that careful justification of screening should be considered before decisions are made to employ the technology. If a decision is made that its use is justified, the framework for protection as a planned exposure situation should be employed, including optimization of protection with the use of dose constraints and the appropriate provisions for authorisation and inspection.

    The biological effects on humans of low-dose and low-dose-rate exposures to ionizing radiation have always been of major interest. The most recent concept as suggested by the International Commission on Radiological Protection (ICRP) is to extrapolate existing epidemiological data at high doses and dose rates down to low doses and low dose rates relevant to radiological protection, using the so-called dose and dose-rate effectiveness factor (DDREF). The present paper summarizes what was presented and discussed by experts from ICRP and Japan at a dedicated workshop on this topic held in May 2015 in Kyoto, Japan. This paper describes the historical development of the DDREF concept in light of emerging scientific evidence on dose and dose-rate effects, summarizes the conclusions recently drawn by a number of international organizations (e.g., BEIR VII, ICRP, SSK, UNSCEAR, and WHO), mentions current scientific efforts to obtain more data on low-dose and low-dose-rate effects at molecular, cellular, animal and human levels, and discusses future options that could be useful to improve and optimize the DDREF concept for the purpose of radiological protection.

    This paper will present some of the key findings of a comparative Latin-American study on radiological risk perception in the health area. The project used a survey method to examine the social demands for information about radiological risks with regard to diagnostic and therapeutic applications. The following topics will be analysed: 1) The role of information as a means for feeling safe; 2) who should inform the public on radiological risks; and 3) what type of information the public would like to receive. A questionnaire was distributed to outpatient samples from ten countries: Argentine, Brazil, Colombia, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Spain, thanks to the collaboration of the different National Radioprotection Societies of the above mentionned countries, and of other concerned professionals (in case they didn't had any association at the time). Correspondence analysis and other techniques of optimal scaling will be used. The paper will discuss the main cross-cultural differences with regard to social demand for information about radiological risks. Our findings may have relevant implications for radiological risks communication programs. (author)

    A review of the role and relevance of the principles of radiation protection of the patient in diagnostic radiology as specified by ICRP has been undertaken when diagnostic risks arising from an examination are taken into account. The increase in population doses arising from diagnostic radiology over the past 20 years has been due to the widespread application of higher dose CT examinations that provide significantly more clinical information. Consequently, diagnostic risks as well as radiation risks need to be considered within the patient radiation protection framework. Justification and optimisation are discussed and the limitations imposed on patient protection by employing only a radiation risk framework is highlighted. The example of radiation protection of the patient in breast screening programmes employing mammography is used to highlight the importance of defined diagnostic outcomes in any effective radiation protection strategy. © The Author 2016.

    The objective of this first European Workshop was to explore further the ethical values underlying the system of radiological protection but also to shed some light on different aspects of the practical implementation of the system that raise ethical questions and value judgments, such as: scientific uncertainty; rationale of the dose limits; stakeholder engagement; and, sustainable development. The workshop has been organized around lectures in plenary sessions, while the discussion activities have been developed within three working groups involving all the participants discussing two questions: - what issues of radiation protection refer to ethics; and what are the ethical values (explicit and implicit) that underlie the system of radiological protection? The present report presents some of the essential points that emerged from the lectures and from the discussion developed around them. It also presents a summary of the main subjects discussed in the working groups, and the main points addressed during the general discussion

    In order to estimate internal dose and derive annual limits of intake for radionuclides in the field of Radiation Protection, it is necessary to study the parameters of ingestion of radionuclides from diet, deposition in tissues and following metabolism of the radionuclides. But these kinds of parameters may be influenced by intake of nutrients and inorganic constituents of diets, for example, a relatively higher uptake rate and longer retention time of radioiodine in thyroid of person who's diet poor of stable iodine. So there is a need to have accurate knowledge of corresponding stable elements intake and their concentration in organs, especially for some trace elements of importance in radiological protection such as Caesium, Iodine, Strontium, Thorium and Uranium. A IAEA RCA CRP on 'Ingestion and organ content of trace elements of importance in Radiological protection' was formulated in 1995 and initiated after the first RCM CRP on the project, held in Manila, Philippine 1-4 July 1996. This is the progress report for studies in China on ingestion and organ content of trace elements of importance in radiological protection after the first RCM

    With this work and employing the radioprotection criterion, the authors pretend to minimize the risks associated to this practice; without losing the quality of the radiologic image. Odontology should perform the following criterions: 1. Justification: all operation of practice that implies exposition to radiations, should be reweighed, through an analysis of risks versus benefits, with the purpose to assure, that the total detriment will be small, compared to resultant benefit of this activity. 2. Optimization: all of the exposures should be maintained as low as reasonable possible, considering the social and economic factors. 3. Dose limit: any dose limit system should be considered as a top condition, nota as an admissible level. (S. Grainger)

    2010-01-01

    According to the Generation IV (Gen IV) Technology Roadmap, Gen IV nuclear energy systems (NESs) should highlight proliferation resistance and physical protection (PR and PP) as one of the four goals along with sustainability, safety and reliability, and economics. Especially, physical protection (PP) is the typical important characteristic of an NES that impedes the theft of materials suitable for nuclear explosives or radiation dispersal devices (RDD) and the sabotage of facilities and transportation by subnation entities and other non-Host State adversaries. These two subjects have been studied separately. Proliferation is commonly considered as an international concern and the past work on the PR assessments can be found. On the other hands, PP is regarded as a State security concern, much of which is classified and facility-dependent. Recently, more concern has been focused on the PP design and regulation because of rapid environment changes including radiological consequences by internal sabotage and nuclear terrorism by RDDs. The current PP Regulation has been applied intensively to the existing nuclear facilities and could be a possible guidance for the future GEN-IV NESs. This paper first reviews the IAEA guide document, INFCIRC/225, which was accepted as the standard international guideline in the physical protection area. It has been updated several times up to now, and is undergoing another revision. The paper introduces current substantial changes in the document regarding PP including the national nuclear security and sabotage in the nuclear facilities. Then, it presents a conceptual framework for physical protection against sabotage considering plant-specific radiological consequence after malicious acts within certain vital areas. The framework combines the newly developed method of vital area identification, the current PSA level 2 works, and physical protection concepts. This would help to improve a design concept of new physical protection

    From the beginning of its industrial activity twenty five years ago, the Juzbado Factory of Enusa Group has always upheld a strong commitment with Radiological Protection and environmental respect and protection. Consequently, the evolution of dose shows a downward trend over the years. Although production has been increased gradually, the average doses to workers have stayed below 1 mSv. In order to identify and prevent the potential environmental impacts of its industrial activity and minimize its impact on the surroundings, the facility develops and environmental management system according to UNE-EN-ISO 14001 since 1999.

  7. The new ICRP recommendations on radiological protection in geological disposal of long-lived solid radioactive waste

    Lochard, Jacques; Schneider, Thierry

    2014-01-01

    Radioactive waste management has been the subject of several recommendations of the International Commission on Radiological Protection (ICRP) since 1985. The aim of the new Publication 122 (2013) is to describe how the 2007 general recommendations of the Commission (Publication 103) can be applied in the context of geological disposal. For this purpose, it is important to emphasise that the new approach developed by ICRP is based on three types of exposure situations: planned, emergency and existing: - Planned exposure situations correspond to situations where exposures result from the operation of deliberately introduced sources. Exposures can be planned and fully controlled. - Emergency exposure situations correspond to situations where exposures result from the loss of control of a source within a planned exposure, or from an unexpected situation (e.g. malevolent event). These situations require urgent actions to prevent or mitigate exposures. - Existing exposure situations correspond to situations where exposures result from sources that already exist when decisions are taken to control them. The characterisation of exposure is therefore a prerequisite for their control. The application of the three basic radiological protection principles - justification, optimisation of protection and limitation of individual doses - are therefore considered in this new framework with justification and optimisation applying to the three types of exposure situations and limitation only to planned exposure situations. The main points highlighted in Publication 122 for the application of the system of radiological protection to geological disposal of long-life solid radioactive waste are summarized

  12. Radiological protection of service and civilian personnel

    International Nuclear Information System (INIS)

    1990-01-01

    Since the United Kingdom's defence nuclear industry was founded in the late 1940s, Service and civilian personnel have been exposed to ionising radiation. During the last forty years, as knowledge about the effects of radiation exposure has grown, concern to ensure adequate protection against exposure has also increased,. As part of our continuing scrutiny of the Ministry of Defence (MoD), we have undertaken a short inquiry to examine MoD's current and future policy and practice on radiological protection. The principal work involving exposure of Service and civilian personnel to significant levels of radiation falls into two discrete areas: the nuclear weapons programme and the nuclear propulsion programme. The nuclear weapons programme involves research, the production of nuclear warheads and their deployment with Her Majesty's Forces. The nuclear propulsion programme involves research, production, operation, refitting and decommissioning of pressurised water reactors as a source of propulsion power in Royal Navy submarines. These two nuclear programmes are not the only sources of ionising radiation within MoD's responsibility: it also arises from research, non-destructive testing and medical applications, most notably conventional radiography. In this Report we have concentrated upon ionising radiation arising from the two defence nuclear programmes. (author)

  13. Accounting for biological effectiveness in radiological protection

    Dennis, J.A.

    1989-01-01

    Relative biological effectiveness (RBE) presents a practical problem to radiological protection when attempts are made to ensure that the assessed risks from different types of radiation and different modes of exposure to radiation are commensurate with one another. Unfortunately, the theoretical understanding of RBE is still in the stage of competing explanations and hypotheses. Furthermore, the division of the concept of dose equivalent into a set of concepts for risk assessment and another set for measurement and control has introduced conflicting requirements of a practical nature that are difficult to resolve. Many of those working in radiobiology and radiation protection have perceived the need to increase the quality factors for photon and neutron radiations. It may be more reasonable to change the quality factors for neutrons than for other radiations. The advantages and disadvantages of different methods for accommodating such changes within the dose-equivalent concepts are to be examined. The method of accommodating such a change that has the least practical disadvantages is to increase the quality factors for all secondary particles produced in tissue by neutron radiations by a constant factor. The only disadvantage would be the perception that the quality factors for these secondary particles were not treated in a consistent fashion for all types of ionising radiation. (author)

    Radiological and environmental protection programs for nuclear facilities have similar goals and objectives, which are basically to protect people and the environment from adverse effects. To be effective, the programs must have organizational independence and a strong commitment from management. In return, the programs should ensure that the facility is operating in full compliance with law and good practice. The scope and elements of radiological environmental protection programs will vary according to facility type and size, with the larger and more complex facilities having a diversity of staff and functions. Examples of good and poor organization charts are given and discussed from the standpoint of program effectiveness along with a discussion of the role of the radiation protection committee. (author)

  16. Radiological protection of patients: conceptual framework and new international recommendations

    International Nuclear Information System (INIS)

    Gisone, Pablo A.; Perez, Maria del R.

    2005-01-01

    Medical exposures represent the largest man-made source of radiation exposure. Within the concept medical exposures includes different kind of exposure: of patients as part of their own medical diagnosis or treatment; of individuals as part of occupational health surveillance; of individuals as part of health screening programs; of volunteers participating in biomedical research programs; of individuals as part of medico-legal procedures and of voluntary patient caregivers (relatives or friends). Radiological protection of patients (RPP) is founded on two basic principles: justification and optimization. The justification of a medical exposure is founded in the consideration that it will give a sufficient net benefit, including the direct health benefits to the patients and the potential benefits to society, against the individual detriment that the exposure might cause, taking into account the efficacy, benefits and risks of available alternative techniques having the same objective but involving no or less exposure to ionizing radiation. Concerning optimization in diagnosis, the radiological protection objective is to keep doses as low as reasonably achievable while obtaining the necessary diagnostic information. In therapy, the objective is to ensure that the target tissue is given the prescribed dose while minimizing the dose to surrounding healthy tissue. In this presentation we analyze new international recommendations concerning RPP, with emphasis in the Directive 97/43/EURATOM. The importance of referral guidelines to help physicians during the process of justification and use of diagnostic reference levels (to help in optimization) is discussed. (author)

    Assessing the potential ecological impact of ionising radiation raises a number of ethical questions. These include fundamental questions such as what exactly constitutes harming the environment, and how the environment should be valued, as well as links to political protection principles such as sustainability and biodiversity. Starting from developments within ecological risk assessment, this paper summarises some of the ethical issues concerning the protection of the environment from radiation. Chapter 2 gives a brief overview of different philosophical and cultural world views on valuing the environment in a context of radiation risk. Chapter 3 addresses some recent challenges to proposed environmental protection frameworks, including practical applications following the Chernobyl and Fukushima accidents, and some scientific developments such as the ecosystem approach. Finally, Chapter 4 offers some recommendations on how ethical evaluation can help produce a more robust and transparent approach to the protection of the environment. In conclusion, there is a need for a holistic evaluation of the environmental impacts of ionising radiation that not only considers the direct consequences on the health of humans and non-human species, but also the more complex social, ethical, and economic consequences of both human and non-human exposures. © The International Society for Prosthetics and Orthotics.

    The system of radiological protection of the environment that is currently under development is one contribution to the general need to adequately protect the environment against stress. Dominated by operational goals, it emphasizes conceptual and methodological approaches that are readily accessible today: reference organisms supported by individual-based traditional ecotoxicological data. Whilst there are immediate advantages to this approach (pragmatism, consistency with other approaches in use for man and biota), there are also clear limitations, especially in a longer run perspective, that need to be acknowledged and further considered. One can mention a few: uncertainties generated by the need for various extrapolations (from lower to higher levels of biological organisation, ...), various features missed such as potential ecological impact through impairment of ecosystem processes, trans-generational impacts as mediated through genomic instability, indirect effects mediated through trophic interactions or disruption of ecological balances, ... Such limitations have already been faced in other fields of environmental protection against other stressors, pushing a number of environment professionals to assign stronger emphasis on more systemic approaches. This review discusses the advantages and limitations of the current approach designed for the radiological protection of non-human biota in the broader context of environment protection as a whole, with especial reference to upcoming trends and evolutions. This leads in particular to advocating the need to boost scientific and methodological approaches featuring the ecosystem concept as a mean to access a unified goal of protection: preserving life sustainability through protection of ecosystem structure and functioning.

    Without adequate and sustainable radiation protection infrastructure, the benefits associated with safe use of nuclear technology and atomic energy might be jeopardized. In the United Republic of Tanzania, the Atomic Energy Act No. 7 of 2003 established the Tanzania Atomic Energy Commission as sole regulatory body responsible for regulating and controlling the safe and peaceful utilization of nuclear technology in the country. The Atomic Energy (Protection from ionizing radiation) Regulations, 2004 further specifies practices designed to ensure that unnecessary exposure of persons to ionizing radiation is avoided, that all exposures are kept as low as reasonably achievable and that all the dose limits specified in the radiation protection standards are not exceeded. This is achieved through the systems of notification, authorizations through registration and licensing, safety and security of radiation sources as well as regulatory inspections and enforcements. These activities are performed by the Commission with operational funds allocated by the Government of Tanzania. The Commission further provides other services namely individual monitoring; calibration services; education and training to radiation workers, public as well as law enforcers; and safe management of radioactive waste. Despite such achievement, still there are a lot to be done in order to strengthen the radiation protection infrastructure in Tanzania. These include issues such as gaps in our legislations, regulations and guidance, security of sources, enforcement of laws, etc. This paper describes and discusses the current status of the regulatory control activities and radiation protection services provided by the Commission and suggestions for further improvement of radiological protection infrastructure in Tanzania.

    Edgardo Rebagliati Martins Hospital of the Peruvian Institute of Social Security started its activities in 1957, as the largest metropolitan general hospital for the insured workers of the I.P.S.S. At present, it has 1350 hospital beds, attends 36,600 external consults per month, about 10,700 x-rays examinations, as well as 16,800 radiotherapy treatments monthly. 200 brachytherapies with Cesium or Radium are performed annually, besides many other (examinations) imaging exams that use ionizing radiation are carried out by our radiology staff with diagnosis or therapeutic purposes. This is the reason why the hospital directory sent some staff physicians abroad to learn all about radiation protection in a hospital setting, so that they will be able to organize a Radiation Protection Committee to advise and to set up rules and regulations to protect exposed personnel, as well as public in general, improving quality and, consequently, saving costs to the institution. The Constitution of the Radiation Protection Committee, its importance in a medical institution, is informed, and finally its experiences of the every day work and how to act in hospital accidents where ionizing radiation is involved, are transmitted.

    Highlights: • Medical students tend to overstate their knowledge of radiation protection (RP). • Overall RP knowledge of young doctors and students is suboptimal. • RP teaching to undergraduates and postgraduates needs to be substantially improved. - Abstract: Purpose: To evaluate the awareness of radiation protection issues and the knowledge of dose levels of imaging procedures among medical students, radiology residents, and radiography students at an academic hospital. Material and methods: A total of 159 young doctors and students (including 60 radiology residents, 56 medical students, and 43 radiography students) were issued a questionnaire consisting of 16 multiple choice questions divided into three separated sections (i.e., demographic data, awareness about radiation protection issues, and knowledge about radiation dose levels of common radiological examinations). Results: Medical students claimed to have at least a good knowledge of radiation protection issues more frequently than radiology residents and radiography students (94.4% vs 55% and 35.7%, respectively; P < 0.05), with no cases of perceived excellent knowledge among radiography students. However, the actual knowledge of essential radiation protection topics such as regulations, patient and tissue susceptibility to radiation damage, professional radiation risk and dose optimisation, as well as of radiation doses delivered by common radiological procedures was significantly worse among medical students than radiology residents and radiography students (P < 0.05). Those latter significantly outperformed radiology residents as to knowledge of radiation protection issues (P < 0.01). Overall, less than 50% of survey respondents correctly answered all questions of the survey. Conclusions: Radiology residents, radiography students and medical students have a limited awareness about radiation protection, with a specific gap of knowledge concerning real radiation doses of daily radiological

  13. The Ethics of Radiological Protection: A Focus on Values and Objectives

    International Nuclear Information System (INIS)

    Clement, Christopher

    2013-01-01

    Christopher Clement emphasised how the RP system is based on science, values and experience and that ethics focuses on values, normative statements, while facts as descriptive statements, are more a question of science. Even full and complete knowledge is not sufficient to decide what ought to be since it is not possible to derive statements of values (what ought to be) from statements of facts (what is). In the case of radiation effects where knowledge is far from complete, value judgements are necessary. Different types of values include aesthetics with beauty and harmony, and ethics with good and right, as values. The RP system relates to human conduct, which is about action and focus on right and wrong actions. The presentation briefly reviewed different schools of ethical though (Aristotele, Bentham and Kant) and theories of normative ethics in particular consequentialism /utilitarianism and deontology. These approaches are elegant, but have flaws. A more complex approach was presented on the basis of Ross indicating that obligations must be balanced depending on each circumstance, where ethical decisions are a matter of balancing potentially conflicting responsibilities or values. A pragmatic approach was proposed, seeking a set of values relevant to the RP system, commonly acceptable to the widest possible range of cultures. The challenge with this approach rests in clarifying the values (responsibilities/duties/obligations) related to the system of radiological protection and at the same time in clarifying the objectives in the protection of people and of the environment. A list of thoughts was proposed, in the final part of the presentation, concerning the objective of providing a reasonable level of protection to all people in medical exposures, occupational and public exposures, which includes: the recognition of the special status of children, acceptable to all, but not necessarily equal for all and a separate treatment for the very small segments of

A laboratory database was used to retrieve all specimens submitted to King Khalid University Hospital, Riyadh, mycobacteriology laboratory for mycobacterial smears and cultures during the period from October 1999-April 2002. Using this database, the original records of the mycobacteriology laboratory and a review of the patient's health records, a standard proforma was completed that included demographic, clinical, radiological and laboratory information on patients included in this study. The patients were divided into 2 groups; the NTM group, which included patients with positive cultures for NTM and the MTB group, which included a sample of patients with documented tuberculosis. During the study period, 286 patients had positive mycobacterial cultures. Seventy patients (24.5%) grew NTM and 216 (75.5%) grew MTB. For patients with MTB, 54 patients were included as per the selection protocol of the study. There was no difference between the 2 groups in all measured demographic variables. The presence of weight loss and fever was significantly more in the MTB group. Radiologically, the presence of hilar adenopathy was more significant among patients with MTB than those with NTM (17% versus 4%, p=0.02). However, bronchiectatic changes were seen significantly more among NTM patients compared to patients with MTB (26% versus 11%, p=0.03). The isolation of NTM in the mycobacteriology laboratory is high. The clinico-radiological features were not sufficiently specific to differentiate patients with NTM from patients with MTB. Local studies are needed to explore NTM disease in various developing countries and identify the NTM species causing infections in non-immunosuppressed patients in each locality. (author)

    The review on radiation protection and safety to the lens of personnel especially in interventional radiology activities has been carried out. The use of radiation in interventional radiology installations provide significant exposure to the lens of the eye, especially personnel. The results of the latest various surveys and researches on the effects of low dose radiation to the eye lens indicates that the eye lens dose threshold is less than the preconceived values. Based on these facts, recently, ICRP and IAEA provides recommendations regarding the reduction of the value of the eye lens dose limit for personnel. BAPETEN have adopted the value of the eye lens dose limit in the development of new regulations on radiation protection and safety. However, the application of this provision has various challenges that BAPETEN provide 3 (three) years transitional period. These challenges include the problem of monitoring the eye lens dose, the eye lens protective equipment which is not adequate, the lack of understanding of personnel related to the risk of low radiation to the eye lens, as well as the proper procedures to mitigate those risks. BAPETEN as a regulatory agency is expected to provide solutions to the problems faced by the stake holders. Therefore, to answer the challenge, it is necessary to develop better monitoring of radiation protection and safety. (author)

    It is widely accepted that Radiological Protection has a real social dimension and it is not restricted to the pure scientific and quantitative aspects. The quality in radiation protection is not reached by simply complying with current technical standards or by enforcing an improved or restricted regulation, but must also be pursued by promoting a culture of radiation protection. An effective dissemination of a radiation protection culture has to include education and training for those students who will become researchers in the involved fields, or who will be called in risk management and, as protection managers, will be asked to inform and train workers or to communicate with the public. Today, in most universities the education in ethics is a significant part of the training in medical, biological and biotechnological curricula but, it is still of poor consideration in those curricula which are traditionally related to Physical Science and even in those areas, like Health Physics, where implementation of interdisciplinary approaches and methodologies are important sources for progress. Moreover, recent advances in the research field of risk perception and communication are very rarely included in those courses. At the Health Physics post-graduate School of Milano State University, within the course of Radiation Protection, a new subject has been recently introduced facing the question of ethical problems and risk perception in radiation protection, and dealing with the activity of international organisations aimed to establish ethical principles for protection against ionising radiation. By referring to this context, students realize how the analysis of radiological risk includes both technological and ethical aspects. The hope is that a new generation of experts in heath physics will promote a dynamic development of knowledge and a higher degree of awareness even in ethical aspects within the academic, institutional or professional fields of radiation

    Full text: As a contribution to the safety culture improvement, the present paper aims at raising awareness about the importance of physical protection measures and, this way, increase the commitment of those responsible for the materials or nuclear installations safety that can cause severe radiological consequences to the public. To that purpose, a brief description is made of the basic criteria used for the design of a Physical Protection System and the introduction of our own computational tool designed and developed by the Nuclear Regulatory Authority to evaluate this type of systems. Likewise, comments are made on the illicit traffic events occurred during the last years involving nuclear materials and other radioactive sources out of some States control, showing that these type of materials are easily accessible and that there are always individuals willing to selling and buying it. Even though events like these won't grant enough uranium or plutonium to fabricate a nuclear weapon, but non-stables isotope and conventional explosives could be mixed to produce a huge contamination. These reported cases had built some public concern and threatened to set a lack of trust on the control systems in use. Even though, no nuclear material diversion and equipment of nuclear interest within the nuclear installations where it is in force the AR 10.13.1 Standard -Physical Protection of Nuclear Materials and Facilities-, have been detected as of today, as a conclusion we must say that only a permanent strengthening of each link of the safety chain will allow a level of an adequate safety. This requires that the already established politics set by the safety authorities reach a high level of commitment by the individuals involved. (author) [es

    In March of 1976 The Royal Commission on Environmental Pollution informed the Board that they had decided to enquire into the organisation for radiological safety in this country, with particular regard to the environmental hazards from radioactivity that might arise from the increasing use of nuclear energy for the generation of electrical power. The Board was invited to submit evidence on any aspects with which it was concerned and, in particular, on its powers and responsibilities and relationships with other bodies; the Board was also asked to discuss the assessment of radiation hazards and the application in practice of the recommendations of the International Commission on Radiological Protection. This is the Board's response. The constitution, functions and responsibilities of the Board are discussed in Chapter 1 as is the involvement of its staff in national and international affairs in the field of radiological protection. Chapter consists of a short statement of the various sources of radiation to which the people of the UK are exposed. The Board does not claim any special experience or expertise in one of the matters referred to in the third area of concern, namely, the criteria used for the siting of nuclear power stations. But in the related field of assessing the environmental consequences of reactor accidents, the Board has been actively involved with the Medical Research Council in their latest review of Emergency Reference Levels - a report on which is shortly to be published. This subject is referred to in Chapter 3 which deals with the methods by which the basic recommendations of the International Commission on Radiological Protection are translated into values that can be applied to particular forms of practice. Chapter 4 discusses the current position of gaseous, liquid and solid wastes arising from nuclear power cycles. It also briefly discusses the way in which this position may change in future and touches on the problems of decommissioning

    The objective of this study was to know the professionals' perception of radiological techniques about radiation protection in the work process in Nuclear Medicine. The research was carried out with nine professionals of the radiological techniques of two private institutions located in the South of Brazil. An interview was applied through recording and transcription. The analysis of the data took place through a thematic analysis. The professionals' perception of radiological techniques regarding the radiological protection in the work process is evidenced when professionals mention the basic rules of radiation protection: time, shielding and distance as attitudes used to minimize the exposure to ionizing radiation. However, it was verified the fragility in the knowledge about the norms and legislation of the radiological protection.

    Full text of publication follows: In order to improve the management of radiation protection at EDF nuclear power plants, the Human Factors Group of the Research and Development Division of EDF has performed some studies on the appropriation process of the radiation protection requirements. These studies have notably shown that an efficient application of the radiation protection requirements lies on a comprehension by all workers of the meaning of these requirements. Furthermore, they should not be applied under the constraint or because of the fear of a sanction, but the workers need to perceive and understand the benefits in terms of protection associated with the radiation protection requirements. The strengthening of the radiation protection culture is therefore a key element of the radiation protection policy developed by EDF. This culture lies on an awareness of the health risks potentially associated with low levels of ionising radiations, as well as on the knowledge of tools, techniques and good practices developed to control the level of exposures and improve the radiation protection. Various type of actions have been undertaken to reinforce among the relevant players (exposed and non-exposed workers, contractors, all levels of management,... ) an awareness of radiation protection in order to integrate it in their day to day work: elaboration of a 'radiation protection system of reference' explaining how the radiation protection regulatory requirements are applied at EDF, publication of a 'radiation protection handbook' available for all workers (including contractors), training sessions, creation of networks of specialists from the various nuclear power plants on specific radiation protection issues, organisation of feed-back experience forum, etc. Beyond these specific actions, i t is also important to ensure a support and an assistance on the field by dedicated specialists. In this perspective, the health physicists have to play a key role in order to

    This project aims the informatization of the radiological protection optimization programs in a single system in order to offer unified programs and inter-related information in Portuguese, providing Brazilian radioactive facilities a complete repository for research, consultation and information. In order to meet both national and international recommendations within the scope of this work, we conducted a comprehensive job of perception about each program contents as well as its real dimension, identifying and detailing the vital parts of programs. The content includes concepts, definitions and theory in addition to the optimization programs, help decision making techniques, information related to protection costs, radiation doses and detriment. The content allows to answer to every question when an optimization program is elaborated, according to decision maker's specific situation. For dimensioning the work of informatization and developing the WEB platform according to the needs of the target public profile, we have conducted an extensive research regarding the possibilities of Information and Communication Technology access in companies throughout the country, which allowed to define the best interfaces tools and resources. The servers processing power added to the technology of relational databases allow to integrate information from different sources, enabling complex queries with reduced response time. The project was implemented in a web environment, using the Web 2.0 tools and resources that allow the entire organizational structure, that would enable the inter-relationships and joints needed for proper use of information technology in radiological protection. This project uses the combination of multiple technologies, maximizing the resources available in each one of them in order to achieve our goals. The investigation of the usage profile for five months enabled important data that suggest new possibilities for the development of computerization of

    The purpose of this document is to provide an updated overview of specific safety and radiological protection issues for all the reactor concepts adopted by the GIF (Generation IV International Forum), independent of their advantages or disadvantages in terms of resource optimization or long-lived-waste reduction. In particular, this new document attempts to bring out the advantages and disadvantages of each concept in terms of safety, taking into account the Western European Nuclear Regulators' Association (WENRA) statement concerning safety objectives for new nuclear power plants. Using an identical framework for each reactor concept (sodium-cooled fast reactors or SFR, high / very-high temperature helium-cooled reactors of V/HTR, gas-cooled fast reactors or GFR, lead-or lead / bismuth-cooled fast reactors or LFR, molten salt reactors or MSR, and supercritical-water-cooled reactors or SCWR), this summary report provides some general conclusions regarding their safety and radiological protection issues, inspired by WENRA's safety objectives and on the basis of available information. Initial lessons drawn from the events at the Fukushima-Daiichi nuclear power plant in March 2011 have also been taken into account in IRSN's analysis of each reactor concept

    1991-01-01

    Finger doses of radiologists and assistants during 19 interventional radiological procedures were measured with thermoluminescent dosimeters (TLDs), and two types of flexible protective gloves were compared with each other. There were considerable differences in doses between different sites of TLDs on fingers. The exact site of TLDs on hands/fingers should thus be reported in papers. Both gloves were also irradiated through an Alderson phantom and the attenuation values were measured. The gloves with slightly greater attenuation proved to be significantly less comfortable to use. Wearing flexible protective gloves did not lengthen screening times as compared to a previous study in the same department. Various aspects of using such gloves are discussed. The attenuation values of gloves reported by the manufacturers may not apply under all clinical circumstances. (orig.) [de

    The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. The present study used a clustered survey design with randomly identified employers in nine occupations. Employees provided questionnaire measures of demographics, personal characteristics (skin type, skin cancer risk perceptions, tanning attitudes, sun-exposure knowledge), personal occupational sun protection practices (exposure reduction, use of sun-protective clothing, sunscreen and shade), workplace sun-protective equipment provision and perceived workplace sun-safety culture. Summative scores were calculated for attitudes, knowledge, workplace provision and culture. A multivariable model was built with worker and workplace variables as plausible predictors of personal sun protection. In this study, 1,061 workers (69% participation) from 112 workplaces provided sufficient information for analysis. Sex, age, prioritized ethnicity, education and risk perception differed significantly between occupational groups (pworkplace sun-protection equipment provision and supportive culture.

    In the Physics Department of the Sciences Faculty of the Universidad Nacional Autonoma de Mexico (UNAM) exist at least 3 sites where radioactive sources and generating equipment s of ionizing radiation are managed: The Modern Physics Laboratory, the Radiological Analysis of Environmental Samples Workshop and the Collisions Workshop; the first of them has two neutron sources, in addition to other emitted sources of gamma and beta radiation. The neutron sources are of Americium 241-Beryllium and other of Californium-252 which have been operated outside of the control of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) that is the regulator organ in Mexico in nuclear matter, because the Operation License No. 183/85, with file number 657 that protected them, lost their validity from August 13, 1987 (25 years behind), what motivated to that the CNSNS assured them. Later to the closing of the Radiological Analysis of Environmental Samples Workshop was believed that a Barium-133 source had been extracted in an illegal way; an investigation realized by the CNSNS determined that the radioactive source was always inside of the detection systems and radiation measurement, for what this source was never lost. In the Collisions Workshop operated an Experimental Accelerator of Particles that the CNSNS prohibited its operation for not having the corresponding license. These examples can be considered as bad practices of radiological protection that should be pointed out to eradicate their promotion and to avoid this way the exposure to the radiation of the occupational exposed personnel and people in general, being also avoided dose of unnecessary radiation. The Instituto Federal de Acceso a la Informacion Publica y Proteccion de Datos (IFAI) in Mexico was a key factor to obtain the information that allowed the realization of this work that was carried out in the Sciences Faculty of the UNAM.

    Exposure to ionizing radiation is a know hazard of radiological procedures. Aim: to compare the emission of secondary ionizing radiation from two coronary angiographic equipments, one with digital and the other with analog image generation. To evaluate the effectiveness of external radiological protection devices. Material and methods: environmental and fluoroscopy generated radiation in the cephalic region of the patient was measured during diagnostic coronary angiographies. Ionizing radiation generated in anterior left oblique protection (ALO) and anterior right oblique protection (ARO) were measured with and without leaded protections. In 19 patients (group 1), a digital equipment was used and in 21 (group 2), an analog equipment. Results: header radiation for group 1 and 2 was 1194±337 and 364±222 μGray/h respectively (p≤0.001). During fluoroscopy and with leaded protection generated radiation for groups 1 and 2 was 612±947 and 70±61μGray/h respectively (p≤0.001). For ALO projection, generated for groups 1 and 2 was 105±47 and 71±192 μGray/h respectively (p≤0.001). During filming the radiation for ALO projection for groups 1 and 2 was 7252±9569 and 1671±2038 μGray/h respectively (p=0.03). Out of the protection zone, registered radiation during fluoroscopy for groups 1 and 2 was 2800±1741 and 1318±954 μGray/h respectively (p≤0.001); during filming, the figures were 15500±5840 and 18961±10599 μGray/h respectively (NS). Conclusions: digital radiological equipment has a lower level of ionizing radiation emission than the analog equipment
