    2001-01-01

    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)

    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

    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)

    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)

    Gilbert, T.L.

    1984-01-01

    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

    As a branch of the Brazilian Nuclear Energy Commission (CNEN), the Institute of Radiation Protection and Dosimetry (IRD) performs extensive activities in the fields of radiation protection, metrology, and dosimetry, as well as specific education, onto a wide operational scope that includes the technical support to national regulatory authorities in the licensing process for nationwide nuclear and radioactive facilities. IRD has several laboratories where are performed radiometric and radiochemical analyses and others radioactivity evaluation procedures in different types of samples obtained in the inspection activities, production of radioactivity metrological standards and reference material by National Laboratory of Metrology of Ionizing Radiation (LMNRI), besides others research activities. In this laboratories can be used sealed or unsealed radioactive sources and radiation-producing devices and are classified with radioactive installations in accordance to national regulations. This way, radioactive liquid effluents can be eventually produced and released into the environment in the course of such activities and an effluent monitoring program to control and reduce the releases to environment is carried out. Additionally, IRD maintains the Radioactive Waste Management Program and Environmental Radiological Monitoring Program (ERMP) in accordance to national regulations requirements. The primary focus of ERMP comprises the validation of the dose prognostics for the public members due to effluents discharge and the provision of consistent projections of the radiation levels at the monitoring sites. In this study, a long term ERMP data survey is discussed, spanning the last thirteen years of activities. On the basis of such discussions and prognostics, it could be observed that the radiological environmental radiological impact due to operation of IRD installations is negligible. (author)

    The U.S. Department of Energy's Radiological Threat Reduction (RTR) Program strives to reduce the threat of a Radiological Dispersion Device (RDD) incident that could affect U.S. interests worldwide. Sandia National Laboratories supports the RTR program on many different levels. Sandia works directly with DOE to develop strategies, including the selection of countries to receive support and the identification of radioactive materials to be protected. Sandia also works with DOE in the development of guidelines and in training DOE project managers in physical protection principles. Other support to DOE includes performing rapid assessments and providing guidance for establishing foreign regulatory and knowledge infrastructure. Sandia works directly with foreign governments to establish cooperative agreements necessary to implement the RTR Program efforts to protect radioactive sources. Once necessary agreements are in place, Sandia works with in-country organizations to implement various security related initiatives, such as installing security systems and searching for (and securing) orphaned radioactive sources. The radioactive materials of interest to the RTR program include Cobalt 60, Cesium 137, Strontium 90, Iridium 192, Radium 226, Plutonium 238, Americium 241, Californium 252, and Others. Security systems are implemented using a standardized approach that provides consistency through out the RTR program efforts at Sandia. The approach incorporates a series of major tasks that overlap in order to provide continuity. The major task sequence is to: Establish in-country contacts - integrators, Obtain material characterizations, Perform site assessments and vulnerability assessments, Develop upgrade plans, Procure and install equipment, Conduct acceptance testing and performance testing, Develop procedures, and Conduct training. Other tasks are incorporated as appropriate and commonly include such as support of reconfiguring infrastructure, and developing security

    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)

Included among these unique approaches were: some nuclear stations had aggressively eliminated most of the plastic materials commonly used in radiologically protected areas (RPA), these included plastic bags, plastic sheeting and plastic sleeving; a few nuclear stations had completely eliminated from the RPA some of the disposable items routinely considered by most nuclear stations as absolutely essential, these included masking tape, duct tape and wood; a couple of leading edge plants were implementing RPA LLW lockout programs in an effort to control absolutely all materials entering or exiting the RPA and making the worker 100% responsible for managing her/his work environment. The above three approaches were so significant in their actual or potential impact that it was decided to initiate an independent research project to evaluate and demonstrate whether all three concepts could be implemented by a single nuclear station and with significant, positive results. This project reports on that research and demonstration project which was implemented at LaSalle and Zion nuclear stations, both of which are operated by Commonwealth Edison Company

  13. Radiological protection in dentistry

    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.

    A brief review is presented of the early and late effects of ionising radiation on man, with particular emphasis on those aspects of importance in radiological protection. The terminology and dose response curves, are explained. Early effects on cells, tissues and whole organs are discussed. Late somatic effects considered include cancer and life-span shortening. Genetic effects are examined. The review is the third of a series of reports which present the fundamentals necessary for an understanding of the basis of regulatory criteria, such as those of the ICRP. (u.K.)

    2013-06-01

    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

    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

    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.

    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

    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)

    There are some sectors in the Health Area of the State University of Campinas (UNICAMP) that present great potential risks from the viewpoint of radiation protection. The aim of this work is to establish the basis a radiological protection program applicable to these sectors. The Diagnostic Radiology Services and the Laboratory of Cardiac Catheterization of the Hospital de Clinicas have been analyzed, as well as the Radiotherapy Services of the Center for Integral Assistance to the Women Health (CAISM). This work was mainly supported by national and international regulations related to the operative and employment aspects of the equipment and radiation sources used in the health area. Regulations related to area and individual monitoring of workers were also used. Results show that the interior of the rooms where the equipment and radiation sources are located is classified as controlled area, whereas the neighborhoods of the rooms are mostly free areas. In order to improve the radiological protection conditions, only some of the operative and employment aspects need to be modified regarding equipment and radiation sources. In this way, routine personal monitoring would not be further required. Since all the workers have their annual mean equivalent doses below 3/10 of the primary limits of the applicable equivalent dose, routine individual monitoring could be exempted.

    In the last years the organizations in charge of the regulation in matter of radiological protection, its have adopted measures to minimize the risks derived of the medical exposures, paying special attention to those that involve women in age of procreation, gestating and in period of lactation, because the embryo - fetus and the newborn babies ones are very vulnerable to the risks of the ionizing radiations, which can end up producing them multiple effects of variable severity. In Cuba, a Maternal-children program that includes the genetic advice to the pregnant woman from the medical point of view exists but didn't so the evaluation of the radiological risk; which is only carried out by the Medical Surveillance Service of the Protection and Hygiene of the Radiations Center (CPHR), without that mediates an official link among both parts and whose existence is only known by a reduced group of professionals of the health and of specialists in Radiological Protection. On the other hand is not established a strategy at national level for the differentiated information and systematic in these topics that it contributes to the control of the exposures of the embryo fetus and the breast-fed baby. Keeping in mind the above-mentioned the specialists of the CPHR have elaborated a proposal of national program for the radiological protection of the embryo- fetus due to the medical exposure of its progenitor. In the same one it is settles down the interrelation between work groups and multidisciplinary institutions to achieve the detection, communication and consultant ship of the cases of exposure to the fetus or breast-fed baby that happen in the country and at the same time include the training so much of the professionals of the health like of the public in general.

    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 radiosanitary hazards that workers of an uranium ore can suffer were studied. The more used control methods for the the evaluation of doses received by the workers was studied too. It was developed a technique using the scintillation chamber method for the detection of radon. Emanation and diffusion methods were used for extraction of radon from water. A program of radiological protection based on ICRP recommendation was analysed for uranium mines. This program includes: ventilation needs calculation methods, a study of radiological protection optimization based on 'cost-benefit' analysis, a monitoring plan and a study about radioactive waste management.

    The purpose of the present work is to find an indicator that permit to evaluate objectively, that is to say through a number, the efficient accomplishment of radiological protection actions that is reflected in an improvement of the safety conditions with which is developed labor. The employed method consists of average evaluation of the individual doses received by the workers pursuing their occupations, measure in a great population, contrasted with the average of environmental dose of located monitors always in the same place. It can be employed film dosimeters, TLD, direct-reading pocket dosimeters with exposure monitor or any combination between them, provided that in the course of the time are compared always the same. Applying this method between the year 1991 to 1997, in part of Santa Fe province (Argentine), is observed that the individual dose average of the workers varies randomly and also rises and decrease unco-ordinately the environmental dose, but relating booth is arrived to a numerical value that has a comparable behavior to the objectively observed.

    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.

    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.

    The benefits of ionizing radiation in the diagnosis and treatment of cancer, as well as other conditions such as cardiac ablation, are well established. However determination, monitoring, and evaluation of patient doses is not as easy task. Furthermore, radiation doses for individual patients may vary greatly from one radiological procedure to another. Attention is needed to reduce unnecessary radiation exposure to patients from All types of radiation producing machines and equipment. The patient risk from radiation injury-stochastic and/or deterministic must be weighted against the benefits of a proper medical examination or treatment as well as the risk of depriving the patient from the necessary medical care. Arbitrary reduction of radiological patient doses without regard to final outcome is determined to proper medical care provided to the patient. Sacrificing image quality in order to reduce patient dose is potentially harmful to the patient as well. Furthermore, the role of radiation exposure incurred from screening procedures such as mammography, needs to be properly considered and differentiated from medically indicated procedures. A known radiation induced risk needs to be balanced against diagnostic efficacy of a screening procedure. In these cases, regulations on standards and guidelines for determination, monitoring, and evaluation of patient doses may be appropriate. In this paper, the technical data collected in the United States have been compared with the corresponding data in Canada. However, even here, it has been recognized that we can not assume that one dose limit fits all. It is advisable to consider individual patient specifics if it means the difference between detection and miss

    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

    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)

    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)

  19. 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

    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)

    The purpose of the Radiological Assistance Program (RAP) is to make DOE resources available and provide emergency assistance to state and local agencies in order to control radiological hazards, protect the public health and safety, and minimize the loss of property. This plan is an integral part of a nationwide program of radiological assistance established by the US DOE, and is implemented on a regional basis. The Brookhaven Area Office (BHO) Radiological Assistance Program is applicable to DOE Region I, which consists of the New England States, New York, New Jersey, Pennsylvania, Delaware, Maryland and the District of Columbia. The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents

    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 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)

'Basic standards for protection against ionizing radiation and for the safety of radiation sources' is promulgated on October, 2002. This basic standard follows the BSS. 'Rule on the administration of radio-diagnosis and radiotherapy', as a order of the Ministry of Health No. 46, is promulgated by Minister of Health on January 24, 2006. It includes general provisions, requirements and practice, establishment and approval of radio-diagnosis and radiotherapy services, safeguards and quality assurance, and so on. There are a series of radiological protection standards and quality control standards in diagnostic radiology, including 'radiological protection standard for the examination in X-ray diagnosis', 'radiological health protection standards for X-ray examination of child-bearing age women and pregnant women', 'radiological protection standards for the children in X-ray diagnosis', 'standards for radiological protection in medical X-ray diagnosis', 'specification for radiological protection monitoring in medical X-ray diagnosis', 'guide for reasonable application of medical X-ray diagnosis', 'general aspects for quality assurance in medical X-ray image of diagnosis', 'specification of image quality control test for the medical X-ray diagnostic equipment', 'specification of image quality assurance test for X-ray equipment for computed tomography', 'specification for testing of quality control in computed radiography (CR)' and 'specification for testing of quality control in X-ray mammography'.

    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.

    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.

    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)

    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

With the birth of the project of the Nuclear Power Plant of Laguna Verde, in the middle of the 1970 decade, the radiological protection in Mexico acquires and additional relevance from different perspective: on the one hand the necessity of the inclusion of a dedicated organization of radiological protection as much of the workers, as if to inhabitants of the zones bordering the nuclear plant. On 1979 it is created the National Commission of Nuclear Safety and Safeguards like exclusively regulating organization in the nuclear and radiological field, which constitutes a landmark in the modern history of the RP in Mexico. The own constant evolution in the RP concepts demands the preparation to confront the new future challenges. (Author)

    nuclear power plants were generally below the target value of 1 GBq per year set by ENSI on the basis of international recommendations with just Muehleberg some 10% above this target value. Draining of the torus was performed there again. Until now, it had contributed several GBq to the release figures, a figure which could now be reduced by a factor of 5. At the Central Interim Storage Facility (Zwilag) and the Paul Scherrer Institute (PSI) the increased releases noted in the 2013 and 2014 have now been stabilised. ENSI conducts inspections and performs comparative measurements to verify that the measuring equipment required for radiological protection is provided, calibrated or standardised correctly, and used appropriately so that it yields accurate measurements. For this purpose, ENSI maintains a test laboratory accredited under ISO 17025. The data from MADUK is made available to the Swiss National Emergency Operations Centre, the German Ministry of the Environment in Baden-Wuerttemberg and the European Radiological Data Exchange Platform (EURDEF) operated by the Joint Research Centre of the European Commission. In addition to the permanent measuring network, mobile probes are also used to measure local dose rates or the gamma spectrum. Typical of their use was their deployment for continuous radioactivity monitoring during containment openings at Beznau. During the reporting year, the LASAT program was introduced for atmospheric dispersion modelling. This uses three-dimensional wind fields with a spatial resolution of 2 km that are provided by the Swiss meteorological service. In 2016 the spatial resolution will be increased to 1 km; it will provide ENSI with a new state-of-the-art tool for use after any incident or accident to create radiological predictions for the areas surrounding nuclear power plants.

    2005-11-01

    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)

    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 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

    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)

    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.

    Thomas, R.H.

    1991-01-01

    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

    International Nuclear Information System (INIS)

    Lazo, E.; Lindvall, C.G.

    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.

    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

    Robb, J.D.; Croft, J.R.

    1992-01-01

    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)

    The application of ICRP recommendations requires knowledge of a variety of concepts and magnitudes. Many of them are employed in other fields of science and precision in its definition reflects this wide application. In this regard, information on quantities and basic units of radiation, which exists in numerous publications, are subjects of great interest. The characteristics and radiation effects are studied by physicists, biologists and chemists mainly. However, there are basics that must be known and to be recognized by general practitioners and specialists from all branches of medicine. The information on quantities and units are used only in radiation protection, have been obtained from the reports listed on the attached bibliography. Such quantities and units contain weighting factors used to provide for different types of radiation and energies that affect the body and thus take into account the relative radio-sensitivity of different tissues. Additionally, they have added a series of data for a better understanding of the units: for example, multiples and sub-multiples, and some examples of converting the units used in radiation protection.

    2008-01-01

    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)

In the ICRP publication 55 the annual protection cost is envisaged as a set of points, each of them representing an option, linked by a straight line. The detriment cost function is considered a linear function whose angular coefficient is determined by the alpha value. In this paper the uranium mine example considered in the ICRP publication 55 was used. But the potential curve was introduced both in the integral cost benefit analysis and in the extended cost-benefit analysis, which the individual dose distribution attribute is added. The result was obtained using derivatives. The detriment cost, Y, is not necessary because the alpha value is known. The Y derivative dS/dY is the alpha value itself and so, the attention is directed to the derivative -dX/dS on the points that, along with the alpha value, present the optimum option. The results makes clear that the prevailing factor in the optimum option selection is the alpha value imputed, and those a single alpha value, as suggested now, probably as little efficiency on the optimization process. Obtaining a curve for the alpha value and using the derivative technique introduced in this paper, the analytical solution is more convenient and reliable compared to the one used now. (authors)

    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.

  11. 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

    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)

    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. To go ahead with these actions, the EC has decided to promote during 2002, a forum with the main Medical European Societies involved in these interventional procedures. (Author)

  17. 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)

  18. Evolution of the radiological protection paradigms

    2009-01-01

    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)

    Here is presented a book published by ICRP ( International Commission Radiological Protection) that exposes the base principles of radiation protection, especially in medical sector. The exposure to ionizing radiations in medicine concerns the persons that profit by a diagnosis or a treatment but also the medical personnel, the patients family and the public. This publication 'CIPR 73' is more particularly adapted to the physicists and physicians implied in radiotherapy, medical imaging, in nuclear medicine and dentistry. It is also useful for the hospital establishments managers and to concerned national authorities. (N.C.)

    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)

  4. Implications of tissue reactions for radiological protection

    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.

    The Safe Sites of Colorado Radiological Safety program has implemented a Safety Coach position, responsible for mentoring workers and line management by providing effective on-the-job radiological skills training and explanation of the rational for radiological safety requirements. This position is significantly different from a traditional classroom instructor or a facility health physicist, and provides workers with a level of radiological safety guidance not routinely provided by typical training programs. Implementation of this position presents a challenge in providing effective instruction, requiring rapport with the radiological worker not typically developed in the routine radiological training environment. The value of this unique training is discussed in perspective with cost-savings through better radiological control. Measures of success were developed to quantify program performance and providing a realistic picture of the benefits of providing one-on-one or small group training. This paper provides a description of the unique features of the program, measures of success for the program, a formula for implementing this program at other facilities, and a strong argument for the success (or failure) of the program in a time of increased radiological safety emphasis and reduced radiological safety budgets.

    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.

    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)

    The US Department of Energy (DOE) has sponsored a Radiological Assistance Program (RAP) since the 1950's. The RAP is designed to make DOE resources available to other DOE facilities, state, tribal, local, private businesses, and individuals for the explicit purpose of assisting during radiological incidents. The DOE has an obligation, through the Atomic Energy Act of 1954, as amended, to provide resources through the Federal Radiological Emergency Response Plan (FRERP, Nov. 1985) in the event of a radiological incident. Toward this end, the RAP program is implemented on a regional basis, and has planned for an incremental response capability with regional coordination between states and DOE response elements. This regional coordination is intended to foster a working relationship between DOE radiological assistance elements and those state, tribal, and local agencies responsible for first response to protect public health and safety

    When a patient is not aware of her pregnancy, the foetus/embryo may be inadvertently irradiated during a diagnostic exploration or therapeutic intervention. The radiosensitivity of the foetus/embryo changes during the different periods of gestation. For this reason there are different risk factors for each moment at which the patient may suffer irradiation. In the past 7 years, the department of Radiophysics and Radiation Protection has been consulted 75 times for this reason, to evaluate the dose received in the uterus.

    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

    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

    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 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

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

    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 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.

    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.

    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

    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.

    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)

    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.

    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 scope of this paper is to summarize the general requirements related to education, training and skill of the individual to obtain the recognition of radiological protection experts on ionizing radiation (experts on radiological protection- RP). There has been established two levels according to the grade of responsibility: Qualified expert provided with a diploma given by de Nuclear Safety Council. Technician expert on radiological protection whose certification is made by the Qualified expert that supervise their work. To obtain the diploma of qualified expert is required an official degree, a title of Architecture, Engineering or equivalent in case of no national degrees; specific training on radiological protection (300 hours) and the knowledge on safety and radiological protection of the facilities to be supervised. Three years of experience on radiological protection must be proved. To get the recognition of technician expert on radiological protection is required Formacion Profesional de Grado Superior or equivalent and specific training on safety and radiological protection. Knowledge on basis and principles of radiological protection are required. According to the type of the facilities to be supervised there are two models: A model: to deal with facilities included in RD 1836/1999 (nuclear and radioactive facilities). B model: to deal with medical X rays facilities approved under RD 1891/1991 three months of experience on the selected model must be proved. (Author)

    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.

    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

    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.

    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)

  8. An Evolved System of Radiological Protection

    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

    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

    Over the past year, the Department of Energy (DOE) Office of Health (EH-40) has taken a leading role in the development of new standardized radiological control training programs for use throughout the DOE complex. The Department promulgated its Radiological Control (RadCon) Manual in June 1992. To ensure consistent application of the criteria presented in the RadCon Manual, standardized radiological control core training courses and training materials have been developed for implementation at all DOE facilities. In producing local training programs, standardized core courses are to be supplemented with site-specific lesson plans, viewgraphs, student handbooks, qualification standards, question banks, and wallet-sized training certificates. Training programs for General Employee Radiological Training, Radiological Worker I and II Training, and Radiological Control Technician Training have been disseminated. Also, training committees under the direction of the Office of Health (EH-40) have been established for the development of additional core training courses, development of examination banks, and the update of the existing core training courses. This paper discusses the current activities and future direction of the DOE radiological control core training program

    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

    A summary is given of legislation concerning health and safety of people as affected by work activities. In connection with legislation in the special field of radiological protection, it was agreed between the (United Kingdom) Health and Safety Executive and the British Dental Association that a survey should be carried out into the use of radiography in dental practices. The terms of the survey, and relevant safety standards, are summarized. The results are discussed under the following headings: personal radiation dose to dental staff, beam filtration, beam diameter, timing units, warning signals, dose per exposure, scattered doserate, film processing, location of the x-ray set, maintenance of the x-ray equipment, holding of dental films, instruction training and supervision. Conclusions are reached, and basic rules proposed. (U.K.)

    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.

    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.

    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

    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.

    Interventional radiology procedures are used for diagnosing certain medical conditions. The radiologists and medical professionals are exposed to ionizing radiation from X-rays of the equipments and also from scattered radiation during these procedures. The radiation exposure to the eye is more important to be assessed while performing such procedures. ICRP has revised the annual dose limit to the lens of the eye from 150 mSv to 20 mSv. In view of this revision, a study was carried out to evaluate the dose to the lens of the eye during interventional radiology. The paper gives the details of calibration of TLDs using a head phantom, predict annual equivalent dose and also highlight the dependence of dose on the position of TLD on the head. It is observed the predicted annual equivalent doses to the lens of eye are in the range of 25 mGy to 37 mGy. The selection of dosimeter placement may also result in an uncertainty of -14% to 20%.

    responder equipped with a radiation detector or a dosimeter. The main impact of such a radiological attack is the contamination of a large areaxxxii. The size of the contaminated area depends on the type and activity of the radioactive material, on the type and geometry of the dispersion device, on the micro-meteorology conditions and on the cross contamination caused by the movement of people inside the contaminated areaxxxiii. Two experimental programs, G reen Field x xxiv (GF) and R ed House x xxv (RH) were recently conducted in Israel in order to increase the preparedness for a RDD event. The GF program aimed at evaluating the consequences of an outdoor and an indoor explosion of an RDD device; while the RH program aimed at evaluating the outcome of a silent dispersion of a radioactive material inside a building. Based on the results of these two experimental programs, the consequences of a possible RDD attack or a silent indoor dispersion of a radioactive material will be given and the necessary preventative steps that can be taken in order to secure NCI's against these threats will be specified

    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)

  6. 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)

The latest results in the continuing survey, which now covers more than 60 non-coal mines employing nearly 2000 men underground, reflect the corrective actions taken in a number of mines by improvements in ventilation management. The survey is now carried out by means of radon flasks supplied by post and returned to the NRPB for measurement. An empirical relationship is used to relate the radon gas and daughter concentrations at different ventilation rates. The results show that there has been a marked decrease (from 42% to 24%) in the number of men exposed above 4 working level months (WLM) in a year, the category requiring supervision (1 to 4 WLM in a year) has increased from 15% to 28%, and the lowest exposure category has increased from 43% to 48%. Although excessive exposures are still a problem, particularly in some tin mines in Cornwall, general compliance with the exposure limit seems possible in the near future. (U.K.)

    With the advent of the EC Patient Directive, the importance of surveying and optimising patient exposure for diagnostic imaging procedures is paramount. In the field of dentistry there has been a heightened interest in areas of equipment performance and patient exposure. This interest, coupled with a number of dental radiation safety incidents investigated by our department, and the issuing of a Code of Practice for Radiological Protection in Dentistry by the Department of Health, led to the establishment in our department, of an evaluation protocol for the performance and operation of dental X ray equipment. The protocol was used to perform a survey on over 100 dental X ray units in use in the Public Sector in Ireland. This presentation will report on the radiation incidents mentioned above. It will detail the protocol and furnish the results and conclusions of the survey. The survey has made it possible to establish clearly the necessary steps required to ensure compliance with requirements. In addition, the corrective steps taken by the dental authorities will be presented and the overall impact of the regulations and the programme consequent on them will be reviewed. (Author)

    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)

    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

    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

    Radiation protection (RP) in industrial applications is composed of four major themes that are recruiting and training personnel, equipment and instrumentation, materials used and also the acquisition of new technologies to improve their own RP. To carry out the recruitment of staff and train them to serve as occupationally exposed personnel in the industry continues with the Mexican Official Standard NOM-031-NUCL-1999, R equirements for qualification and training of personnel occupationally exposed to radiation ionizing , what will be done regarding the physical fitness of personnel by NOM-026-NUCL-1999, M edical surveillance of personnel occupationally exposed to ionizing radiation . The principle of optimization of the RP, or ALARA principle (keeping the risk as low as reasonably achievable), is assumed to be the safety philosophy in the field of industrial applications of ionizing radiation. Practically all the elements that make up the equipment, instrumentation and materials used in industrial radiography and other industrial applications, has an orientation towards the protection, along with procedures that operate. For example, in industrial radiography the technician always has several instruments for radiation detection and measurement, some with visible and audible alarms. The equipment characteristics and transport (containers) are regulated by the standards NOM-025/1- 2000 and NOM-025/2-2996, which contains requirements for radiological safety in design and operation, respectively, for both as containers for some of its parts and accessories. As part of the technological innovation with benefits to the RP itself and eventually target practice today are venturing into the radiography digital, which involves the exposure of a plate image phosphorus-based with the later download to a computer. In combination with the use of sources of X-rays, there is a real contribution to reducing the dose, since the later are nowadays equipped with programmable

    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

    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 present ARMS aircraft has an effective survey time of four hours. Typical survey altitudes are 300 to 500 feet for terrain surveys and up to 20,000 feet for cloud tracks. A number of special airframe modifications have been made to accommodate the various sensor systems. The ARMS radiation measurement system consists of fourteen 4-inch diameter by 4-inch thick sodium iodide (NaI) detectors, a summing network for the detector signals, single and multichannel analyzers, analog computers, digital display and recording equipment, a doppler radar position computer, and strip chart recorders. Major subsystems include meteorology sensors, multispectral camera systems, and an infrared scanner for thermal mapping. Additional radiation detectors include an alpha spectrometer and a beta counter, used to count filter samples taken from a 150 cfm air sampler, which is a permanent part of the aircraft. A small lead shield houses a 1 / 2 -in. x 3-in. NaI crystal for beta and gamma counting of air filter samples. Several BF 3 neutron detectors are also available for neutron counting. The raw data from the gross gamma count and the gamma spectral measurements are permanently recorded on paper tape, and they must undergo reduction and analysis for final characterization of the radiological properties of the surveyed area.

    With medical radiation exposures to mankind ranking the highest among man-made radiation, radiation protection safeguards have to be put in place in all countries. Competent authorities should have the legal legislation and adequate infrastructure to ensure implementation, enforcement and compliance with the radiation protection standards. Justification, optimization, quality assurance and control are to be the guiding ideals for those who prescribe and/or carry out radiographic procedures. Radiation dose limitation in medical practices is to be encouraged so far as it does not compromise image quality and the provision of a direct benefit to the exposed individual. (author)

    In compliance with the current laws, radiation protection (RP) training is required during the formative programs of certain Health Sciences specialties. Laws entrust to official bodies in specialized training the adoption of necessary measures to coordinate and ensure a correct implementation. The aim of this study is to describe Community of Madrid experience in RP training to specialists during their formative programs, and to determine the number of residents trained and analyze their satisfaction level with the training. A descriptive cross-sectional study was performed, including all training specialists from the Community of Madrid during the 2007-2011 period. We determined the number of residents trained per year and we evaluated their satisfaction level with the training through a survey. A total of 55 training courses were carried out and 5820 residents have been trained during the 2007-2011 period. the student satisfaction level with the training has increased gradually from 6.1 points in 2007 to 7.0 points in 2011. The development of the RP formative program for residents in the Community of Madrid has meant the start up o the necessary official mechanisms to ensure the quality and adequacy of training in this area, covering the formative needs of the collective.

    This presentation sharing experiences which correspond to the nuclear power plant of Laguna Verde. This nuclear power plant is located at level 2 of four possible, in the classification performance of the World Association of Nuclear Operators (WANO), which means the mexican nuclear power plant is classified in terms of its performance indicators and above the average achieved by their counterparts americans and canadians. In the national context, the nuclear power plant of Laguna Verde has also been honored with several awards such as the National Quality Award, the Clean Industry Certificate, the distinction of Environmental Excellence and others of similar importance. For the standards of WANO, the basic idea is that there are shortcomings in one of nuclear power plant concern to all partners. The indicators used for the classification will always go beyond more compliance with regulations, which are assumed, and rather assume come or a path to excellence. Among the most important indicators are: the collective dose, the percentage of areas declared as contaminated, the number, type and tendency of contamination personal cases, the number of dosimetry alarms, the number of unplanned exposures, loss control of high radiation areas and the release of contaminated material outside the restricted areas. Furthermore, as already indicated, nuclear power plants are of special care situations, such as, carrying out work in areas with radiation fields of more than 15 mSv h -1 , the movement of spent fuel in the reload floor. The consideration of the minimum total effective dose equivalent as a criterion for prescribing tools that reduce exposures, but may increase the external cases of contaminated casualties, the experience in portals such as workers subject to radiology, where exposure in industrial radiography, and so on. Special mention deserve the conditions generated during fuel reload stops, which causes a massive personnel movement, working simultaneously on

    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

    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).

    Aiming to elaborate a methodology to optimize the performance of the Radiology Service of the Military Police Hospital, in Rio dee Janeiro, some goals were established: improvement of the attendance to patients; improvement of the qualification of technicians; achievement and maintenance of high degrees of quality in each step of the radiological process; improvement of the image quality; optimization of dose per examination and cost reduction. The procedure used to detect faults in the radiological process was the analysis of causes of film losses. Results show a 70% reduction in the film rejection rate. 74% of total identified faults were due to equipment, 11% to films, 10% to patients and 5% to developing. The reduction in the cost of developed film reached 75%. A training course given to the staff of the radiological service fully reached its goals, contributing, with the staff motivation, mostly to the success of the program. This success indicates that, with a serious persistent work, it is possible to offer to patients services within their expectations, even at a public hospital. Such programs should be supported by health authorities, not only due to their technical and economic needs but, mostly, due to their social implications. (author). 10 refs., 11 figs

    To analyze the current situation about the pedagogic information on radiological protection training which could be found in Internet. More than 756 web-pages have been visited in Internet about Radiological Protection in the nuclear and medical fields, providing information mainly focusing on information to the members of the public. In this search were used internet Searching Appliance (as Copernicus, Google and Scirus), using key words related with this subject (as Radiological Protection and Health Safety), getting the internet address of organizations, societies and investigation groups. Only a low percentage (less than 5 per cent) of these addresses content information on Radiological Protection for the members of the public, including information about the regulator Organizations, and which are the objectives for protection of the members of the public against ionization radiation (from the point of view of the use of the ionization radiation in the medical and nuclear field). This work attempts to propose the use of internet as a tool for informing the members of the public in matter of radiological protection, as first link in the chain of the training and education.

    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 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)

    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)

    After an initial period of conviction for installing an active discussion on Radiation Protection of Patients inside the medical community, there were organized working groups in Radiodiagnosis, Radiotherapy, Nuclear Medicine and on radiation protection of pregnant women. These groups began systematical activities, which received a strong institutional support of the Argentine Society of Radiology, toward the implementation of a Program of RPP that is being put nowadays into practice. This program has three aims and a series of targets to be fulfilled in successive stages: Basic aims and short term targets: 1) To guarantee the Justification. First goal: Development of the Prescription Guide (achieve) 2) To optimize the radioprotection: First goal: Development of a Manual of Procedures (achieved) 3) To prevent potential exposures. First goal: Design of a Basic Quality System in Health (achieved) The effective participation of the professional's and technician's associations in the development of the program of radiological protection of the patient is a key aspect for the success.

    2015-06-01

    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 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

    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)

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

    International Nuclear Information System (INIS)

    Costa, Rogerio Ferreira da

    2013-01-01

    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.

  14. Radiological protection, from regulation to culture

    Boehler, M.C.

    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)

    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

    This work describes the work done in the implementation of an educational project which aims the formation of technical-professional in radiation protection (RP) with official recognition in Mexico. The constant growth of business activities related to the use of radioactive material in industry, medicine and research has required the development and implementation of standardization by the regulatory authorities of our country. However the advance with regards to training of specialized personnel is reduced in comparison to current needs. in our country there is no technical personnel with studies recognised by the regulatory body in this specialty (RP), however quality assurance programs currently require an educational training that will help to meet the standards in the various activities that develop in the use and handling of sources and ionizing radiation generating equipment, reason why it was developed and implemented this educational project. Additionally induce and promote the need for the peaceful use of nuclear energy and ionizing radiation, at the national level is one more reason to implement the programme at upper secondary level, with the purpose to have knowledge related to the topic. The technical course has a duration of six semesters (three years), and currently there are two generations of graduating. The plan of study consists of the required disciplines for upper secondary level more plus those corresponding to technological training in radiological protection

    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

This course is given to groups from local, county, state, and federal agencies and industrial organizations. It is normally three days in length, although the structure is flexible to accommodate individual needs and prior training. An important feature of the course is an emergency exercise utilizing a short lived radionuclide to better simulate real accident conditions. Groups are encouraged to use their own instruments to gain better familiarity with their operating characteristics under field conditions. Immediately following the exercise, a critical review of the students' performance is conducted

    During calendar year (CY) 1999, the Pacific Northwest National Laboratory (PNNL) performed its customary radiological protection support services in support of the U.S. Department of Energy (DOE) Richland Operations Office (RL) and the Hanford contractors. These services included: (1) external dosimetry, (2) internal dosimetry, (3) in vivo measurements, (4) radiological records, (5) instrument calibration and evaluation, and (6) calibration of radiation sources traceable to the National Institute of Standards and Technology (NIST). The services were provided under a number of programs as summarized here. Along with providing site-wide nuclear accident and environmental dosimetry capabilities, the Hanford External Dosimetry Program (HEDP) supports Hanford radiation protection programs by providing external radiation monitoring capabilities for all Hanford workers and visitors to help ensure their health and safety. Processing volumes decreased in CY 1999 relative to prior years for all types of dosimeters, with an overall decrease of 19%. During 1999, the HEDP passed the National Voluntary Laboratory Accreditation Program (NVLAP) performance testing criteria in 15 different categories. HEDP computers and processors were tested and upgraded to become Year 2000 (Y2K) compliant. Several changes and improvements were made to enhance the interpretation of dosimeter results. The Hanford Internal Dosimetry Program (HIDP) provides for the assessment and documentation of occupational dose from intakes of radionuclides at the Hanford Site. Performance problems carried over from CY 1998 continued to plague the in vitro bioassay contractor. A new contract was awarded for the in vitro bioassay program. A new computer system was put into routine operation by the in vivo bioassay program. Several changes to HIDP protocols were made that were related to bioassay grace periods, using field data to characterize the amount of alpha activity present and using a new default particle

    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

    2015-01-01

    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)

    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.

    This plan of monitoring radiological environmental routine fits on environmental policy of CNEA, satisfying national and international recommendations for licensed facilities. Sampling matrices are related to direct routes of exposure: air and water (river, lake, sediments, drinking water). Soil samples are also analyzed for having integrated matrices. They are considered as minimum three points of measurement: a white point (water or winds up), a point of maximum (water or winds down) and a point corresponding to the location of the individual representative or a point of public interest. Measurements in air estimate KERMA rate with thermoluminescent dosimeters, bi-monthly, and concentrations of particulate material and aerosols. For water samples (monthly), soil and sediments (quarterly), radionuclides that have download limits are analyzed, according to its importance in the dosages produced in the representative individual. In these cases artificial radionuclides using gamma spectrometry, beta total and Sr-90 by radiochemical techniques if the value of total screening (1 Bq/L) is exceeded. Foods are not included because no possible matrices were detected, either by their distance. by located not predominant wind direction. They are however still looking for milk producers that fulfills the minimum requirements.The data collected are compared with environmental baselines to set trends that might point to future significant changes in the environment during the life of the facilities. So far it was not observed significant differences with respect to baseline values

    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 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.

    The key factor in medical exposure is justification, that is ensuring that the benefit exceeds the risk. Nuclear medicine studies are comparable in cost to more sophisticated radiological tests such as ultrasound, computed tomography or magnetic resonance. Radiation doses are similar from X ray and nuclear medicine procedures. Having justified exposures the next step is optimization, namely using a radiation dose as low as is reasonably practicable. Diagnostic reference levels may be set nationally or locally such that the balance of diagnostic quality and radiation burden is optimized. In therapy the aim is to achieve a therapeutic dose while keeping the dose to non-target tissues as low as reasonably practicable. Variations in activities may be required for overweight patients, those in severe pain, those with certain conditions and in the case of tomography. Any woman who has missed a period should be assumed to be pregnant; there should be notices to patients emphasizing this. Following the administration of longer lived pharmaceuticals it is important to avoid pregnancy for a time such that the dose to a foetus will not exceed 1 mGy. A similar situation applies to a child who is being breastfed when a mother receives a radiopharmaceutical. In the case of children undergoing investigations the activity needs to be reduced to maintain the same count density as in adults. With the administration of an incorrect pharmaceutical an attempt should be made to enhance excretion, and the referring doctor and the patient should be informed. Extravasation usually requires no action. Positron emission tomography results in higher doses both to staff and patients. Research should use subjects over the age of 50, and avoid anyone who is pregnant or is a child. Nuclear medicine procedures result in a very small loss in life expectancy compared with other common risks. (author)

    Full text. In the context of occupational and populational exposure the concepts of optimization are implemented widely, at least conceptually, by the relevant authorities and the responsible for radiation protection. In the case of medical exposures this is not so common since the patient is exposed deliberately and cannot be isolated from his environment. The concepts and the instruments of optimization in these cases are discussed with emphasis to the ICRP recommendations in Publication 73. (author)

    The author aims at providing citizen with knowledge in the field of health in relationship with nuclear energy. A first part proposes a historical overview of knowledge of nuclear effects on health, with references to the discovery and first works on radioactivity, to the Manhattan project, to the creation of national and international bodies in charge of nuclear issues, to various nuclear accidents and their consequences. In the second part, the author describes mechanisms of radiation protection and its organisation at the world level (ICRP, UNSCEAR, IAEA, and so on), and discusses in a very critical way the basic aspects which are now governing radiation protection standards. Indeed, he outlines denials, lies, and the inappropriate character of the risk model created in 1951. He also discusses the optimisation principle, criticises the application of deterministic effect criteria to stochastic effects. In the fourth part, the author analyses consequences of the present official radiation protection which he considers as a pseudo-science as shown by misleading assessments of Chernobyl victims, and by publications which also criticise this science. The last part addresses the specific case of France

    Currently there is a vast research about the harmful effects of the use of ionizing radiation in medical procedures and in recent years struck by the rapid innovation in imaging equipment, considerably increasing the radiation dose received both patients and professionals in the radiodiagnosis area, service having the greatest demand in our country. The main strategy that has so far is education, that is, to inform all those involved in managing ionizing radiation about the applications and risks associated with them. Generally it requires that all personnel occupationally exposed attesting a course of radiation protection. However, the high demand for this type of medical services and poorly trained staff, makes taking a classroom course for personnel occupationally exposed is complicated. So that in the Instituto Politecnico Nacional (IPN) we are designing a course in radiation protection to be implemented online, through the virtual platform Moodle in a first stage, and a massive open online course as the second stage so that can be carried by anyone interested in the subject, without having to appear in person. This will allows to reach the largest possible number of personnel occupationally exposed to just have a computer with internet access. (Author)

    In Uruguay the lack of Radiation Protection (RP) laws makes education in medical use of ionizing radiations at University, a decisive factor of changes. The six years experience in teaching technicians, radiologists, interventional cardiologists and anesthetists in curricular lectures, continuing education courses and workshops, show the importance of a close link between educators and occupationally exposed professionals. Regarding training and education in the optimization of the procedures, it is essential that both teacher and student comprehend the exact meaning of ALARA concept. This implies that although the educator is the one who manages the physical basis of RP, the student is who teaches the educator about the procedures. This turns RP education into a dynamic process in which at the same time, both educator and student learn and teach. After the theoretical lectures, it is essential that students show their ability in applying the acquired knowledge in their everyday practice. Last nut not least, in order to fulfill the first RP principle,all medicine students need to be educated in RP and quality image criteria before the get their medical doctor degree. Our experience shows that RP education in diagnostic radiology requires an expert with both medical physics and Image technology knowledge that allow an approach to students work, language and everyday problems. Despite the fact that the main result of the Education Program is the way professionals improve their practice, another consequence was that the Regulatory Authority of the country called the teacher team to coordinate the first RP national course.

  13. 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)

  14. Concepts of collective dose in radiological protection

    International Nuclear Information System (INIS)

    Lindell, B.

    1985-01-01

    The collective dose (S) is the product of the number of individuals exposed and their average radiation dose. ''Radiation dose'' is usually taken to be the effective dose equivalent (Hsub(E)) as defined by the ICRP. The unit of the collective dose is then the man.sievert (man.Sv). The following four applications of the collective dose are the most common: (a) in the assessment of the highest per caput dose rate in the future from a continued practice which exposes some critical group or the population as a whole to radiation; (b) in the limitation of present radiation sources, if it is believed that additional sources in the future may add to the per caput dose in a population so that it might reach unacceptable levels unless all sources are controlled at an early stage; (c) as an input to justification assessments, indicating the total detriment from a certain practice; and (d) as an input to optimization assessments as the basis for costing detriment in differential cost-benefit analyses of protection arrangements. It is sometimes said that the collective dose is a useful quantity only if the assumption of a non-threshold, linear dose-response relation is valid. This assumption is not always necessary. Applications (a) and (b) are possible without any assumption on the dose-response relationship at very low doses. Only applications (c) and (d) require the assumption of a non-threshold, linear dose-response relation. Some hesitation in using the collective dose originates in distrust in the biological assumptions implied by uses (c) and (d), but also in lack of confidence in the meaningfulness of collective doses that have been derived by adding dose contributions over very long time periods. However, none of the four applications (a) - (d) is by necessity related to extreme time scales. That problem mainly arises in the assessment of radioactive waste repositories

    The preliminary results of a program undertaken to estimate the doses to patients associated with dental radiology practices in Argentine, are presented. Information collected from the search demonstrated that the Dieck and coronal techniques are the most commonly used practices, while all the examinations are performed by using a circular collimator. For both practices, the dosimetric studies were carried out on a Rando Alderson phantom. All dose measurements were made using thermoluminescent detectors LiF and Ca 2 F. In addition, a mathematical model was developed by applying the Monte Carlo method to a MIRD-V phantom. Circular and rectangular collimators were used. Absorbed dose distribution on head and neck, as well as surface dose distribution, were estimated. The comparison of the performance of both collimators shows that the use of the rectangular one allows for a dose reduction of 80%. Besides, a good correlation between the physical and mathematical models applied was found. (author)

    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 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

    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.

    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

  1. Protective effect of lead aprons in medical radiology

    Huyskens, C.J.

    1995-01-01

    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

  2. Radiation and man. From radiology to radiation protection

    International Nuclear Information System (INIS)

    2005-04-01

    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)

    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)

  7. Training in radiological protection - a pool of practical exercises

    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)

    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)

    ICRP was established in 1928 as the International X-ray and Radium Protection Committee. In 1950 the name was changed to reflect the wider scope of radiological protection. The present membership of the Main Commission and its four committees was established in July 1993 for the period 1993-1997. Their programmes of work are now nearing completion with the Committees having met four times and their progress is summarised. The Main Commission meets in November 1996, when one of the main topics will be the election of the new Commission and members of the four Committees for the period 1997-2001

    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

    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.

    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.

    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.

    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

  20. 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

    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)

    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.

    To determine the gender distribution of radiology residency programs and identify associations with radiology departmental factors. The residency programs affiliated with the top 50 research medical school from US News and World Report were identified. The gender of all radiology residency graduates from each program from 2011 to 2015 were collected. Radiology departmental factors were collected: gender of chairperson, gender of program director, gender of faculty, geographic location, and city population of the residency program. The median percentage of female radiology faculty and residents were calculated and classified as above or below the median. Comparisons were made between residency programs and departmental factors via a Pearson χ 2 univariate test or logistic regression. There were 618 (27.9%) female and 1,598 (72.1%) male residents in our study, with a median female representation of 26.4% in each program. Programs with a female residency program director were significantly more likely to have an above-median percentage of female residents versus a male program director (68.4% versus 38.7%, P = .04). Programs in the Northeast (70.6%) and West (70.0%) had higher above-median female representation than the South (10.0%) and Midwest (38.5%, P < .01). There was no association with city population size (P = .40), gender of faculty (P = .40), residency size (P = .91), or faculty size (P = .15). Radiology residency programs with a female residency program director and those in the Northeast or West have a greater concentration of female residents. Residency programs that aim to increase female representation should investigate modifiable factors that can improve their recruitment practices. Copyright © 2017 American College of Radiology.

    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.

    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.

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.

    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

  10. The regulatory application of authorization in radiological protection

    International Nuclear Information System (INIS)

    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.

    In this report we present the results about radiation controls during 1990 - 2010, carried out in the Nuclear Reactor RP-10 of the Nuclear Center of Huarangal. These controls and radiological evaluation are of much utility for the radio personnel protection of this one and other reactors, since it allows to compares these variables with respect to the time. From the results obtained in monitoring and radiation controls, we conclude that in no case it has been reached the limits allowed by the Peruvian Regulating Authority. (author)

    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)

    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.

    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.)

    2006-01-01

    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

    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.

    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

    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)

    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)

    2001-01-01

    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

    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)

    Full text: As in other countries, life expectancy is increasing in Brazil, and the number of radiological examinations tends to increase. Old equipment and high technology ones cohabit, radiology technicians are not well prepared to conduct practices, images and doses to patients are not optimized. Digital techniques that began to be introduced in the last years are also an important issue, because, as it is possible to modify the image digitally, there is less concern about the choice of equipment parameters that produce the best-image/lowest-dose compromise. Pediatric radiology, CT and fluoroscopy require attention too, as they are of dosimetric interest or because the patient ages imply higher risks or because the techniques deliver higher doses than the conventional ones. In our opinion, the most important role that we can play is educating and forming people to work in this area: training programs and refreshing courses are a way of facing the problem. This way, we are organizing, in a technical cooperation with IAEA, two training courses in quality assurance and radiation protection in radiology, one designed to physicists (60 h), and the radiological technicians (40 h). An important cooperation with a paediatric and a general hospital made it possible to offer courses with 50% practical lessons, performed both in the University and in hospital equipment. Both courses cover a basic Radiation Physics program, radiation protection, image formation and quality control in conventional and digital equipment, and patient dosimetry. Equipment donated by IAEA facilitate the practical QA and dosimetry lessons. The rationale of our project is making it sustainable through the formation of physicists that will go on in the education process of technicians in technical schools. We present the results of the first two courses (physicists and technicians), considering the selection process, the development of the activities, and the assessment both of the students enrolled

    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 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.

    to the patient, c) making selective use of high dose rate mode, by prior identification situations in which this use is really necessary, d) changing the projection possible, and d) performing simple constancy checks to detect malfunctions in the automatic control systems. 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 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

    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

  19. 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

    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

    After an initial period of conviction for installing an active discussion on Radiation Protection of Patients inside the medical community, there were organized 'working groups' in Radiodiagnosis, Radiotherapy, Nuclear Medicine and on radiation protection of pregnant women. These groups began systematical activities, which received a strong institutional support of the Argentine Society of Radiology, toward the implementation of a 'Program of RPP' that is being put nowadays into practice. The rapid advances which are present in medicine today, both in equipment and work protocol, determine that 'norms and regulations never arrive on time' which is why it is paramount that health services have 'systems of dynamic quality' and 'continual improvement' that can be adapted quickly to changes. This program has 6 principal aims and a series of targets to be fulfilled in successive stages: Basic aims and short term targets: 1) To guarantee the Justification. First goal: Development of the 'Prescription Guide' (achieved); 2) To optimize the radioprotection: First goal: Development of a 'Manual of Procedures' (In process); 3) To prevent potential exposures. First goal: Design of a 'Basic Quality System' in Health (achieved); 4) To achieve a qualification of the professionals by means of a process of certification and re-certification (In process); 5) To spread PRP's criteria by means of chats, meetings and the use of the media and graphical means. (Partially fulfilled); 6) To establish criteria for the protection of patient and operators in Interventional Radiology by creating a referral service. Strategies to cope with different interests within society are described. Main problems, failures and difficulties are also described. The effective participation of the professional and technicians' associations in the development of the program for radiation protection of the patient is a key aspect for the success of the whole national programme.

    In a benchmarking process, parameters related to patient doses and image quality were compared in x-ray examinations from 10 radiology departments in western Sweden. One main object of the project was to form a pedagogical process focussing on radiation protection and quality matters by engaging radiographers and radiologists from the departments in practical project work and optimisation discussions. Anatomical phantoms with simulated pathology were used for standardised entrance dose measurements and exposure of phantom images. Radiographer performance, such as centering and collimation, was evaluated by radiographers. Radiologists evaluated clinical images using revised CEC quality criteria. The results of the measurements showed significant differences between the departments both for image quality, entrance dose and the performance of examinations. Explanations to these differences were in many cases found in the choice of equipment, working methods etc. (au)

  4. The effect of radiological protection standards on the uranium market

    1975-01-01

    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

    The medical use of ionizing radiation started at the beginning of the century. It has always been considered necessary, as well as for diagnostic applications where exposure to the patient is the price to pay in order to obtain useful images, as for therapy where the patient is exposed on purpose, in order to kill malignant cells. It is nowadays the major man-made contribution to the population dose. Even with the developments of substitutive imaging or treatment techniques, there is still an increasing demand and many organizations are joining their efforts to try to keep the dose to the patient 'as low as reasonably achievable'. This is particularly the case for the International Commission on Radiological Protection (ICRP) which recommended in publication 26 to follow three main principles: justification, optimisation and limitation. Limitation, however, does not apply to patients since the individuals exposed are expected to benefit from this exposure, but justification and optimization are relevant. (author)

    Studies on the genetics, cytogenetics, biochemistry and molecular biology of neoplasia are now beginning to provide us with an increasingly coherent picture of cancer induction and development. Some of the genes involved in this complex multi-step cellular process have been isolated and characterized and in a few instances it is possible to identify target genes for the initiation of specific neoplasms and how these genes are mutated by environmental carcinogens. Knowledge of molecular mechanisms of mammalian DNA repair and mutagenesis has similarly increased and, together with limited studies of molecular mechanisms of radiation oncogenesis in animal systems, allows specific comment on the molecular nature of radiation-induced initiating events for neoplasia. These data are discussed with an emphasis on their possible implications for radiological protection. (author)

    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

The generation of images in the municipal net is performed in conventional manner. Since 2009 works a maintenance associated with the verification of the performance of radiological equipment (annual) and processing (monthly) one. In 2008, on the occasion of the agreement between the city hall and FIDI, conditions were evaluated for radiological protection in 52 care units of the municipality. Were carried out verification tests of performance in conventional equipment, mammographic and tomographic equipment, in 138 and 71 analog processors, according to current legislation. In 2008 , 33 % of the devices had technical problems that prevented its operation. Currently only 3.4 % of the 91 are in radiological equipment maintenance. In 2008 the majority of radiological equipment had more than 10 years of manufacturing, while today fixed equipment have been replaced by new ones and therefore the use of mammography and generally have 2 to 3 years of manufacture . Currently the 31 processors are operative in 2008, 28 % were out of order. The replacement of most of the equipment associated with program quality and preventive/corrective maintenance has kept the service in accordance with the law. (author)

    US Department of Energy (DOE) Order 5400.1 requires the establishment of a groundwater protection management program to ensure compliance with DOE requirements and applicable Federal, state, and local laws and regulations. The Uranium Mill Tailings Remedial Action (UMTRA) Project Office has prepared a ''Groundwater Protection Management Program Plan'' (groundwater protection plan) of sufficient scope and detail to reflect the program's significance and address the seven activities required in DOE Order 5400.1, Chapter 3, for special program planning. The groundwater protection plan highlights the methods designed to preserve, protect, and monitor groundwater resources at UMTRA Project processing and disposal sites. The plan includes an overview of the remedial action status at the 24 designated processing sites and identifies project technical guidance documents and site-specific documents for the UMTRA groundwater protection management program. In addition, the groundwater protection plan addresses the general information required to develop a water resources protection strategy at the permanent disposal sites. Finally, the plan describes ongoing activities that are in various stages of development at UMTRA sites (long-term care at disposal sites and groundwater restoration at processing sites). This plan will be reviewed annually and updated every 3 years in accordance with DOE Order 5400.1

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

    International Nuclear Information System (INIS)

    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

    The EU Council Directive 97/43/EURATOM (MED) states that Member States shall ensure that adequate theoretical and practical training is provided for dental practitioners working with ionising radiation; this also includes the provision of continuing education and training programmes, post-qualification. The area of dental radiology is specifically mentioned in this legally binding document. The Dept. of Medical Physics and Bioengineering, St James's Hospital, Dublin, is particularly interested in the area of radiation protection training and routinely provides educational courses both at national and international levels. A recent review of their dental radiation protection course was undertaken in conjunction with a number of Principal Dental Surgeons within the Health Service Executive in Ireland. The revised course was delivered to over 200 dental staff members at two separate meetings during 2006. The response from attendees was very positive. It is proposed to extend this course to other dental professionals, working both in the Irish private and public health sectors in the future. (authors)

    The EU Council Directive 97\\/43\\/EURATOM (MED) states that Member States shall ensure that adequate theoretical and practical training is provided for dental practitioners working with ionising radiation; this also includes the provision of continuing education and training programmes, post-qualification. The area of dental radiology is specifically mentioned in this legally binding document. The Department of Medical Physics and Bioengineering, St James\\'s Hospital, Dublin, is particularly interested in the area of radiation protection training and routinely provides educational courses both at national and international levels. A recent review of their dental radiation protection course was undertaken in conjunction with a number of Principal Dental Surgeons within the Health Service Executive in Ireland. The revised course was delivered to over 200 dental staff members at two separate meetings during 2006. The response from attendees was very positive.

    2011-06-01

    The RPII's remit is very broad. It includes three main pillars; regulating all uses of ionising radiation; assessing people's exposure to ionising radiation; advising Government and the public on the prevention of unnecessary exposure. This plan builds on the previous Strategic Plan for 2008 to 2012 and sets out clearly the developments we expect over the planning period, the strategic priorities we are commiting to, along with a clear description of how we will address these priorities. Four key strategic priorities and associated objectives have been developed for this period. The key themes underpinning all four strategic priorities are public value, transparency, communication and sustainability. The priorities are; to provide the expertise, technical capability and information essential to the protection of the Irish population and the environment; to regulate the safe and secure use of ionising radiation in Ireland in a sustainable and transparent manner; to work in partnership with others to implement national radiological protection initiatives; to deliver value to the public in everything we do

    For operational effectiveness, ICRP built a dosimetric system based on the additivity of the effects whatever are the nature of the radiation and the origin of the exposure, external or internal. This system fulfilled the assigned role; the assessment of the protection against radiation is good. Today, the challenge to overcome with regard of the nuclear energy is to make the demonstration that the management of disposed wastes in geological formations will be without risk to the future generations. The scenario considered is related to the return towards the biosphere and an internal contamination by ingestion of long-lived radionuclides. Is the current radiological protection system adapted to this situation? What means irradiation alpha? What does one really know in dosimetric and risk terms for the chronicity of internal exposures? As many questions for which we always do not have the answer and that it is thus necessary to consider at the time when one recommends a dialogue with the stakeholders and that recent scientific observations call into question many certainties. New research programmes in radio toxicology appear absolutely necessary to answer these legitimate questions. The example of the step of pharmaceutical industry for obtaining the marketing authorizations of the drugs is to be meditated. (author)

    Dental radiology uses X-ray technology to diagnose and design treatment of various clinical problems related to the oral cavity and surrounding tissues. As technology quickly evolves, there are numerous X-ray modalities using different tools in the attempt to best image and treat efficiently these diseases, disorders or other related clinical conditions. The reported numbers of dental X-rays, the fact that these may be under-reported in many countries and because dental X-rays are performed more on younger individuals, whose teeth and dentition are still developing, calls for increased need on radiation protection. The objectives of this paper are to report on the latest technology updates and related radiation protection issues, to present future directions and define gaps. Most of existing radiation protection national and international guidelines are more than a decade old. Update is needed to account for newer technologies such as cone beam computed tomography (CBCT) and digital imaging. Diagnostic Reference Levels (DRLs), a well established method for dose optimization, are not yet defined for CBCT and have to be set for various clinical indications. As far as shielding is concerned, recent data confirm that use of lead apron, even in pregnant patients, or gonadal shielding are not recommended, due to negligible radiation dose reduction. Thyroid lead shielding should be used in case the organ is in or close to the primary beam. Specifically for CBCT, leaded glasses, thyroid collars and collimation (smaller field of view (FOV) especially for paediatric patients) minimize the dose to organs outside the FOV.

    Maintenance of Certification (MOC) recognizes that in addition to medical knowledge, several essential elements involved in delivering quality care must be developed and maintained throughout one's career. The MOC process is designed to facilitate and document the professional development of each diplomate of The American Board of Radiology (ABR) through its focus on the essential elements of quality care in Diagnostic Radiology and its subspecialties, and in the specialties of Radiation Oncology and Radiologic Physics. The initial elements of the ABR-MOC have been developed in accord with guidelines of The American Board of Medical Specialties. All diplomates with a ten-year, time-limited primary certificate in Diagnostic Radiologic Physics, Therapeutic Radiologic Physics, or Medical Nuclear Physics who wish to maintain certification must successfully complete the requirements of the appropriate ABR-MOC program for their specialty. Holders of multiple certificates must meet ABR-MOC requirements specific to the certificates held. Diplomates with lifelong certificates are not required to participate in the MOC, but are strongly encouraged to do so. MOC is based on documentation of individual participation in the four components of MOC: (1) professional standing, (2) lifelong learning and self-assessment, (3) cognitive expertise, and (4) performance in practice. Within these components, MOC addresses six competencies: medical knowledge, patient care, interpersonal and communication skills, professionalism, practice-based learning and improvement, and systems-based practice

    The International Commission on Radiological Protection (ICRP) is an independent, international organization that advances for the public benefit the science of radiological protection, in particular by providing recommendations and guidance on all aspects of protection against ionizing radiation. This presentation touches on aspects of The 2007 Recommendations of the ICRP, a fundamental document that lays out the system of radiological protection for all exposure situations and types, and focuses on other recent publications relevant to the uranium industry. Of particular relevance are the 2009 ICRP Statement on Radon and the accompanying report on lung cancer risk from radon. (author)

    From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. 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

    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.

    radiotherapy owing to an ageing population. In addition, further growth in medical radiology can be expected in developing States, where at present facilities and services are often lacking. The risks associated with these expected increases in medical exposures should be outweighed by the benefits. For the purposes of radiation protection, ionizing radiation exposures are divided into three types: Medical exposure, which is mainly the exposure of patients as part of their diagnosis or treatment (see below); Occupational exposure, which is the exposure of workers incurred in the course of their work, with some specific exclusions; and Public exposure, which comprises all other exposures of members of the public that are susceptible to human control. Medical exposure is defined in the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS, the Standards) as: 'Exposure incurred by patients as part of their own medical or dental diagnosis or treatment; by persons, other than those occupationally exposed, knowingly while voluntarily helping in the support and comfort of patients; and by volunteers in a programme of biomedical research involving their exposure.' This Safety Guide covers all of the medical exposures defined above, with emphasis on the radiological protection of patients, but does not cover exposures of workers or the public derived from the application of medical radiation sources. Guidance relating to these exposures can be found in the Safety Guide on Occupational Radiation Protection. In addition to the IAEA, several intergovernmental and international organizations, among them the European Commission, the International Commission on Radiological Protection (ICRP), the Pan American Health Organization (PAHO) and the World Health Organization (WHO), have already published numerous recommendations, guides and codes of practice relevant to this subject area.

    . (A set of key examples is listed herein.) In our view, the current system comprising of the dose limit (1 mSv pa) and the ALARA Principle provides the necessary flexibility and tools to regulators for addressing any country specific or site specific settings, and there are already good examples of this. Again, we believe that this matter is best left for discussion and agreement between the local stakeholders rather than at an international level. We strongly support the need to establish an international approach to defining a level of dose below which society may legitimately maintain that an individual is adequately protected., and hence the allocation of further resources to control the source on radiological health grounds would be inappropriate. WNA considers that this dose is not less than a few tens of micro-sieverts. This approach should be supported by guidance on the appropriate level of conservatism within dose assessments, both in the context of exclusion/clearance/exemption and critical groups in general. WNA supports the continued use of the term 'ALARA, economic and social factors being taken into account'. Collective dose is a useful concept in the optimisation of occupational exposure: in addition it needs to be supplemented by the consideration of the number of workers exposed at the higher levels and by wider pragmatic experience. Public collective dose is of very limited utility in decision making, and little if any weight should be given to exposures at long timescales and exceedingly trivial levels of individual exposure. WNA welcomes both the lead taken by ICRP to bring the protection of non-human biota into a coherent overall framework addressing the totality of radiological protection, and the recognition that the current system has in practice provided an appropriate standard of environmental protection. On this basis the development of the future system of protection must not impose a disproportionate burden on operators. The focus for

    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.

    1983-01-01

    The most recent recommendations of the International Commission on Radiological Protection in its Publication 26 differ from all those made earlier by being based quantitatively on the risk of deleterious effects. Two types of effect are considered: stochastic and non-stochastic effects. The recommended dose limits are designed to avoid non-stochastic effects and reduce the risks of stochastic effects to acceptable values. The dose equivalent limits are only part of a much wider system that requires justification for the use of sources of ionizing radiation and consideration of costs and benefits to ensure that doses are kept as low as reasonably achievable. Annual Limits for Intakes (ALIs) of radionuclides by workers are recommended in ICRP Publication 30 and the dosimetric models and sources of data used to derive these values are described. ICRP are currently considering a statement about values of ALI for members of the public. The many factors by which these would differ from those recommended for workers are discussed. (author)

    The history, objectives, structures and functions of the International Electrotechnical Commission (IEC) and the International Organisation for Standardisation (ISO) are summarized. The IEC is affiliated to the ISO as its electrical division, but has technical and financial autonomy. Member countries of the EEC may be committed to the adoption of their formal agreements ('Standards') if these become incorporated as Directives. The national standardisation organisations, such as BSI in the U.K., form national committees and are responsible for submitting to the IEC the co-ordinated national viewpoints on particular subjects. The overall links between the technical committees and sub-committees of the ISO, IEC and BSI in the field of radiological protection are tabulated, and the relevant International Standards produced, or in the course of preparation, by the appropriate committees of the ISO and the IEC are listed. The bulk of the effort of the BSI committees is now aimed at the production of acceptable international standards. Compatible national standards then follow. This policy is in contrast to the earlier initial emphasis on national standards, and the improved international collaboration has had two welcome effects. The selection of proposals for standards is more critical, and compatibility with the relevant ICRP and ICRU publications is almost a prerequisite for any international standard. (U.K.)

    2008-01-01

    Embalse NPP dry-stores used fuel elements in concrete silos inside the premises: The fuel elements are kept for at least 6 years in pools located in the controlled area , before being moved into the silos. This paper describes the radiological protection for the different stages of the process, i.e., when the used fuel elements are moved from the pools into the silos, and while they are kept in the concrete silos. The occupational exposure of the personnel operating this system at each stage is showed, as well as the environmental dose rates around the silos, and the dose rate in the shields used during the transfer. These environmental dose rates are assessed with portable instruments and with TLD dosimeters placed around the silos. This paper also describes the periodical routine control performed every two years in the atmosphere inside the silo, the moisture control and the detection of possible aerosols (in some cases, traces of krypton 85 were detected). It is important to point out that the maximum equivalent environmental dose rate H* (10) detected at approximately 20 metres from the silos is overly low: (0.35 micro sievert / hour). Our experience demonstrates that dry storage is totally compatible with the environment and with the ALARA criterion for personnel's doses. (author)

    2013-01-01

    Chieko Kurihara suggested the bio-ethics principles of autonomy, beneficence and justice as related and linked to those ones of radiological protection, justification, optimization and dose limit, by giving the bases for an introductory discussion around them and the RP system. The second part of the presentation focused on ethical considerations about actual issues which happened in Fukushima, by analyzing and studying them from different perspectives and points of view: logistics, communication, evacuation-return processes, aspects such as compensation, conflict of interests and future perspectives. For example a lack of logistic in repairing the facilities, evacuation and elimination of contaminated land contributed in the distrustfulness of public; lay-experts, learning from anti-nuke experts have been communicating about radiation risk; mandatory evacuation was criticized by considering other types of impact resulting from the evacuation itself. Also decision-making about returning is always difficult in view of the protection of vulnerable groups such as of elderly, children and fetus while hot discussions were opened on the basis of to which extent damage resulting from radiation exposure should be compensated and the level of epidemiological survey. A significant part of criticisms started about the conflict of interest among NPP related companies, government, students with great attention of the public. Within the conclusions it was highlighted the need to make RP system working well and properly, especially in emergency situations and this could be improved if the RP system, well before emergency situations, is understood at least by politicians and stakeholders and implemented in governmental policies and regulations, with ethical justifications

    2001-01-01

    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.

    2010-01-01

    The authors have developed a comprehensive radiology quality assurance (QA) program that evaluates radiology interpretations and procedures by comparing them with reference standards. Performance metrics are calculated and then compared with benchmarks or goals on the basis of published multicenter data and meta-analyses. Additional workload for physicians is kept to a minimum by having trained allied health staff members perform the comparisons of radiology reports with the reference standards. The performance metrics tracked by the QA program include the accuracy of CT colonography for detecting polyps, the false-negative rate for mammographic detection of breast cancer, the accuracy of CT angiography detection of coronary artery stenosis, the accuracy of meniscal tear detection on MRI, the accuracy of carotid artery stenosis detection on MR angiography, the accuracy of parathyroid adenoma detection by parathyroid scintigraphy, the success rate for obtaining cortical tissue on ultrasound-guided core biopsies of pelvic renal transplants, and the technical success rate for peripheral arterial angioplasty procedures. In contrast with peer-review programs, this reference standard-based QA program minimizes the possibilities of reviewer bias and erroneous second reviewer interpretations. The more objective assessment of performance afforded by the QA program will provide data that can easily be used for education and management conferences, research projects, and multicenter evaluations. Additionally, such performance data could be used by radiology departments to demonstrate their value over nonradiology competitors to referring clinicians, hospitals, patients, and third-party payers.

  11. Reflections on a peculiar bet for the future's radiological protection

    International Nuclear Information System (INIS)

    O'Donnell, P.

    2000-01-01

    Wishing to make fruitless certain types of speculations and wanting to avoid the perplexity that can provoke a strict application of the actual system, Roger Clarke, Chairman of ICRP, has been proposing, for a year now, a new protection frame. In this article, the main aspects of his proposal and the consequences of its implantation are analysed. To express his principles, Clarke has settled a new term, the controllable dose. The author believes that naming under the same concept different sources and exposures, avoiding a separate treatment of them, could create a more balance outlook on the public's perception from radiological risk, somewhat distant from the facts. The author shares the idea of establishing a general principle based on the individual's protection, but does not see the need of rejecting the collective dose concept, especially in occupational exposure, and its role on optimisation and justification principles. Justification has been one of the less used and understood principles in the practice. Few are the counties that have thoroughly regulated their application, apart from naming it. Nonetheless, the author does not share the attitude of giving up under the weight of the evidence, and would rather persuade on the need of rationalisation in regulating the practices through justification. The author firmly believes that the use of this principle should be established more explicitly, through a balanced distribution of different roles which different institutions must act. Accordingly to the author, Clarke's approach has distorted the principle of optimisation in more ambiguous and less compromising terms. There is however one aspect, which the author considers more significant, the evolution taking place in its praxis and, in particular, within the nuclear power plants organisations. The author highlights that this principle has transformed into a personal challenge for workers and managers, moving from radiological expert to performer's field

    A brief description of some of the applications of computers in a radiological survey program is presented. It has been our experience that computers and computer software have allowed our staff personnel to more productively use their time by using computers to perform the mechanical acquisition, analyses, and storage of data. It is hoped that other organizations may similarly profit from this experience. This effort will ultimately minimize errors and reduce program costs

    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

    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.

    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.

    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.

  18. 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)

    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

  3. Interactive, Computer-Based Training Program for Radiological Workers

    Lawrence Livermore National Laboratory (LLNL) is redesigning its Computer-Based Training (CBT) program for radiological workers. The redesign represents a major effort to produce a single, highly interactive and flexible CBT program that will meet the training needs of a wide range of radiological workers--from researchers and x-ray operators to individuals working in tritium, uranium, plutonium, and accelerator facilities. The new CBT program addresses the broad diversity of backgrounds found at a national laboratory. When a training audience is homogeneous in terms of education level and type of work performed, it is difficult to duplicate the effectiveness of a flexible, technically competent instructor who can tailor a course to the express needs and concerns of a course's participants. Unfortunately, such homogeneity is rare. At LLNL, they have a diverse workforce engaged in a wide range of radiological activities, from the fairly common to the quite exotic. As a result, the Laboratory must offer a wide variety of radiological worker courses. These include a general contamination-control course in addition to radioactive-material-handling courses for both low-level laboratory (i.e., bench-top) activities as well as high-level work in tritium, uranium, and plutonium facilities. They also offer training courses for employees who work with radiation-generating devices--x-ray, accelerator, and E-beam operators, for instance. However, even with the number and variety of courses the Laboratory offers, they are constrained by the diversity of backgrounds (i.e., knowledge and experience) of those to be trained. Moreover, time constraints often preclude in-depth coverage of site- and/or task-specific details. In response to this situation, several years ago LLNL began moving toward computer-based training for radiological workers. Today, that CBT effort includes a general radiological safety course developed by the Department of Energy's Hanford facility and a

    The Radiological Safety Analysis Computer Program (RSAC-5) calculates the consequences of the release of radionuclides to the atmosphere. Using a personal computer, a user can generate a fission product inventory from either reactor operating history or nuclear criticalities. RSAC-5 models the effects of high-efficiency particulate air filters or other cleanup systems and calculates decay and ingrowth during transport through processes, facilities, and the environment. Doses are calculated through the inhalation, immersion, ground surface, and ingestion pathways. RSAC+, a menu-driven companion program to RSAC-5, assists users in creating and running RSAC-5 input files. This user's manual contains the mathematical models and operating instructions for RSAC-5 and RSAC+. Instructions, screens, and examples are provided to guide the user through the functions provided by RSAC-5 and RSAC+. These programs are designed for users who are familiar with radiological dose assessment methods

    1996-10-01

    Following the Chernobyl accident a programme of monitoring and research was initiated in the Radiological Protection Institute of Ireland to address questions concerning the immediate and longer term impact of the fallout. Prior to the Chernobyl accident the scientific literature contained limited information on the behaviour of radionuclides in the environment and their entry into food-chains. In response to this lack of information the monitoring programme assessed the contamination status following the accident, while the research programme was aimed at gaining a fuller understanding of the processes of radionuclide transfer. Investigations were undertaken into the pathways through which Chernobyl radionuclides may be transferred to man i.e. via agricultural crops, meat and milk production. The results showed that the behaviour of the fallout radionuclides is complex and highly variable, being influenced by weather, topography, season, crop type, land management etc. The research continues today and its aim is to identify pathways of radiation dose transfer to man and to determine strategies for minimising risk and cost to man and the environment. Examination of the factors which control radionuclide behaviour has revealed practical strategies for dealing with contaminated lands and foods. A significant factor controlling the behaviour of radionuclides in ecosystems is the physico-chemical characteristics of the soil. These physico-chemical characteristics have proved to be useful parameters which can be manipulated to reduce the transfer of radionuclides in agricultural systems. In semi-natural ecosystems (peatlands and commercial forests) the controls on the behaviour of radionuclides are generally more complicated and intervention is more difficult. These ecosystems present a challenge in terms of the identification of possible practical rehabilitation measures. (Abstract Truncated)

  6. Adaptive Response- A Universal Phenomenon for Radiological Protection

    International Nuclear Information System (INIS)

    Streffer, C.

    2004-01-01

    Predominantly with cells in vitro but also with whole animals in vivo it bas been shown that small radiation doses like other stress factors can render cells or organisms to a stage of higher radioresistance. This has been demonstrated with chromosomal aberrations gene mutation, cell transformation and survival. However, it is necessary to keep the appropriate conditions in a very stringent way. This implies radiation dose ranges, time factors and others. The adaptive response is transient and keeps for about three cell cycles or two to three days for mammalian cells. Most studies have been performed with low LET radiation. From the few data with high LET radiation it can be concluded that the adaptive response is much less or does not occur at all. Cellular and molecular studies indicate that the DNA repair is most important for the induction of adaptive response although the understanding of the mechanisms is certainly incomplete. In vivo other biological phenomena like the immune system also play a significant role. A high individual variability exists with respect to the extent of the adaptive response. No adaptive response apparently occurs with cells from individuals with repair-and immune-deficiencies. Several experiments during the prenatal development indicate that there is no or only little adaptive response during wide developmental stages in utero. Therefore it must be concluded that the adaptive response has limitations and is not a universal principle. Due to these restrictions of the validity and strength of adaptive response it is doubtful whether adaptive response can generally be applied in the practice of radiological protection.

    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.

    The use of interventional radiology procedures has considerably increased in recent years, as has the number of related medicolegal litigations. This study aimed to highlight the problems underlying malpractice claims in interventional radiology and to assess the importance of the informed consent process. The authors examined all insurance claims relating to presumed errors in interventional radiology filed by radiologists over a period of 14 years after isolating them from the insurance database of all radiologists registered with the Italian Society of Medical Radiology (SIRM) between 1 January1993 and 31 December 2006. In the period considered, 98 malpractice claims were filed against radiologists who had performed interventional radiology procedures. In 21 cases (21.4%), the event had caused the patient's death. In >80% of cases, the event occurred in a public facility. The risk of a malpractice claim for a radiologist practising interventional procedures is 47 per 1,000, which corresponds to one malpractice claim for each 231 years of activity. Interventional radiology, a discipline with a biological risk profile similar to that of surgery, exposes practitioners to a high risk of medicolegal litigation both because of problems intrinsic to the techniques used and because of the need to operate on severely ill patients with compromised clinical status. Litigation prevention largely depends on both reducing the rate of medical error and providing the patient with correct and coherent information. Adopting good radiological practices, scrupulous review of procedures and efficiency of the instruments used and audit of organisational and management processes are all factors that can help reduce the likelihood of error. Improving communication techniques while safeguarding the patient's right to autonomy also implies adopting clear and rigorous processes for obtaining the patient's informed consent to the medical procedure.

    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)

    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.

    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.

  5. Annual Report and Accounts 2000 Radiological Protection Institute of Ireland

    2002-01-01

    This report outlines the work of the Radiological Protection Institute of Ireland (RPII) during 2000. The report highlights its report published a year ago on the safety of the storage tanks holding liquid high-level radioactive waste at Sellafield. This report has gained heightened relevance from the fear, following September 11, of a terrorist attack on Sellafield. Also detailed in the report is the programme of monitoring of the radioactive contamination of the Irish sea caused by discharges from Sellafield which continues to be an important area of the Institute's work. A major focus is on the levels of technetium-99, which rose sharply from 1994 to 1998. Since 1998 these levels have begun to decrease, but are still considerably above pre-1994 levels, and remain a significant cause of concern. Also of considerable current interest is the key role assigned to the Institute under the National Emergency Plan for Nuclear Accidents. The Institute has further developed the capability of the computer model ARGOS (Accident Reporting and Guiding Operational System), which would enable it to predict the dispersion pattern of a plume of radioactive material being transported in the atmosphere towards Ireland from a disaster at a nuclear installation overseas. This prediction would be a vital element in ensuring an optimum response to a nuclear disaster affecting Ireland. The lung cancer risk associated with exposure to high levels of naturally occurring radon gas in buildings continues to be an important concern for the Institute. The Institute's nationwide survey of radon levels in primary and secondary level schools, commissioned by the Minister for Education and Science, and aimed at eliminating the exposure of children and staff to elevated radon levels in schools, has been highly successful and is entering its final stages. New legislation introduced in 2000 addresses the issue of radon in workplaces, and the Institute's implementation of this legislation has got

    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

    International Nuclear Information System (INIS)

    Ramos, L. M.

    2000-01-01

    Radioactive contamination of the environment and public exposure to ionizing radiation may result from releases from programmed or accidental operations in regulated activities, or they may be due to preexisting situations such as contamination caused by past accidents, radioactive rain caused by nuclear tests, or increased natural radioactivity resulting from human activities. In many cases, both the emission sources and the environment should be monitored to determine the risk to the population and verify to what extent the limits and conditions established by competent authorities are being observed. Monitoring can be divided into three categories: monitoring of the emission source, of the receiving medium and of members of the public; individual monitoring of the population is extremely rare and would only be considered when estimated doses substantially exceed the annual public dose limit. In practices likely to produce significant radioactive releases, as is the case of nuclear fuel cycle facilities, the limits and conditions for monitoring and controlling them and the requirements for environmental radiological monitoring are established in the licensing process. Programs implemented during normal operation of the facilities form the basis for monitoring in the event of accidents. in addition to environmental radiological monitoring associated with facilities, different countries have monitoring programs outside the facilities zones of influence, in order to ascertain the nationwide radiological fund and determine possible increases in this fund. In Spain, the facilities that generate radioactive waste have effluent storage, treatment and removal systems and radiological monitoring programs based on site and discharge characteristics. The environmental radiological monitoring system is composed of the network implemented by the owners in the nuclear fuel cycle facilities zones of influence, and by nationwide monitoring networks managed by the Consejo de

    The Radiation Protection and Dosimetry Institute of the National Nuclear Energy Commission (IRD/CNEN) and the Radiodiagnostic Service of the Rio de Janeiro Federal University Hospital, have been engaged in the development of quality control programs applied to radiodiagnostics, one of them concerning gastrointestinal fluoroscopy. Since fluoroscopy examinations normally deal with high doses, they represent an important fraction of public exposure. They deserve special attention and the risks to patients should be considered individually, not only as a population statistics. Another target should be the search for procedures that reduce doses to patients and, therefore, reduce dose to medical staff involved. This work describes steps followed and results obtained in the estimation of doses for patients and physicians. Investigated examinations were esophagography, gastroduodenal seriographic and colon with double contrast media, using conventional equipment with fluorescent screens, carried on by physicians engaged in the first year of medical residence.

    In response to a Department of Energy Office of Security Evaluations study on radiological and toxicological sabotage, the Under Secretary of Energy has directed that all departmental elements initiate analyses to determine the extent of radiological and toxicological sabotage threats within the department. To accomplish this, a plan was adopted whereby radioactive and other hazardous materials at DOE sites would be assessed by an interdisciplinary team as to quantities, ranked according to their hazards, subjected to a vulnerability assessment, and appropriate upgrades selected and monitored. This paper is a discussion of those efforts

    Biological radiation effects such as somatic certainty effects, somatic stochastic effects and genetic effects are described. Diagnostic radiology, therefore, involves risk to the patient in case of undesirable exposures and in particular to the fetus. Gonad doses in diagnostic radiology which may lead to genetic effects have been found to vary within a wide range. To avoid somatic certainty and to keep genetic effects to a minimum, some suggestions are enumerated. They deal with the choice of technique, proper positioning, use of calibrated equipment and use of techniques like xerography, ultrasonography, thermography etc. (M.G.B.)

    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.

    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)

    This program plan meets all the requirements identified in DOE Order 5530.3, Radiological Assistance Program and supports those requirements leading to the establishment of a Federal Radiological Monitoring and Assessment Center (FRMAC) as required by DOE 5530-5. Requests for radiological assistance may come from other DOE facilities, Federal or state agencies, tribal officials, or from any private corporation or individual. Many of the requests will be handled by a telephone call, a conference or a letter, teletype or memorandum. Other requests for assistance may involve radioactive material in serious accidents, fire, personal injuries, contamination or possible hazards to the general public. Some occurrences may require the dispatch of trained personnel equipped with radiation monitoring instruments and related equipment necessary to evaluate, control and neutralize the hazard. The primary responsibility for incidents involving radioactive material always remains with the party having custody of the radioactive materials. In addition, the DOE recognizes that the assistance provided shall not in any way preempt state, tribal, or local authority and/or responsibility on state or tribal properties. Toward this end, DOE assistance for non-DOE radioactive materials, is limited to technical assistance, advice, measurement and other resources as deemed necessary by the local authorities but excludes DOE interface with the public media. This is a function handled by the local or state Incident Commander

    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

    2003-01-01

    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)

    The purpose of our study was to compare various aspects of radiology training schemes in ten countries. A questionnaire was sent to senior residents in the UK, USA, Canada, Australia, New Zealand, Italy, Egypt, India, Malaysia and Greece. The questions concerned length of training, required pre-training experience, the organization of the training scheme, teaching, resources, stages at which residents can independently perform and report examinations, fellowships, and progression to jobs. A wide variety of training, ranging from highly scheduled programs with detailed aims and objectives, to self-learning occurs across the world. Examinations and assessments are also variable. There are lessons to be learned from varying practices; more exchanges of ideas should be encouraged. In view of the ''internationalization'' of radiology services and the variation in training styles an international qualification for quality assurance purposes may be desirable. (orig.)

    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.

    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.

    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.

    Computers have become increasingly important in data analysis and data management as well as assisting in report preparation in the Oak Ridge National Laboratory (ORNL) Radiological Survey Activities (RASA) Program. The primary function of the RASA program is to collect, analyze, report, and manage data collected to characterize the radiological condition of potentially contaminated sites identified in the Department of Energy's (DOE) remedial action programs. Three different computer systems are routinely utilized in ORNL/RASA operations. Two of these systems are employed in specific functions. A Nuclear Data (ND) 682 is used to perform isotopic analysis of gamma spectroscopic data generated by high-purity germanium detectors for air, water and soil samples. The ND682 employs a 16,000-channel analyzer that is routinely used with four germanium spectrometers. Word processing and data management are accomplished using the INtext system implemented on a DEC PDP-11 computer. A group of personal computers are used to perform a diverse number of functions. These computer systems are Commodore Business Machines (CBM) Model 8032 with a dual floppy disk storage medium and line printers (with optional X-Y plotters). The CBM's are utilized for: (1) data analysis -- raw data from radiation detection instrumentation are stored and manipulated with customized computer programs; (2) data reduction -- raw data are converted into report-ready tables using customized programs; (3) data management -- radionuclide data on each air, water and soil sample are stored on diskettes along with location of archived samples; and (4) program management -- site surveys and report status are tracked by computer files as well as program budget information to provide contemporary information of program status

  16. Radiological protection aspects of geological disposal of high-level radioactive waste

    1992-01-01

    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.

    Faced with the increasing exposure of the population to ionizing radiations and the need to respect users' rights, political and scientific efforts have been undertaken in order to improve image quality in radiodiagnostics and reduce risks to patients. In Brazil, in the past 20 years, a low rate of investment in this area and inadequate health policies have lead to diagnostic radiology services of poor quality. For their part, scientific societies, professional associations and the Ministry of Health have issued federal and state norms which require the control of physical parameters of the radiological equipment. Consequently, there is a need to create a National Reference Laboratory to oversee, inspect and evaluate the implementation of such norms. Another topic addressed in this article is the professional profile of the Medical Physics Specialist. (author)

    A diagnosis carried out five years ago showed that in Petroleos de Venezuela (PDVSA) and its subsidiaries, exist about 530 radioactive sources. Also, about 1500 workers were also occupationally exposed, during operations such as industrial radiography and well logging. The same study determined the occurrence of some non-reported accidents and incidents with the overexposure of workers, specially contractors. Most of these problems were the result of the bad application of the radiological protection practices, and on the other hand, the disregarding of the governmental authorities in applying the regulatory standards. In order to solve this situation, PDVSA settled the safety guide for working with ionizing radiation, in which guidelines and technical advice are stablished to perform a safer work with radioactive elements. A radiological protection program was also organized in all the company operational areas. The paper includes the programs, practices and procedures implemented by PDVSA and its subsidiaries. Besides, the result of applying this comprehensive radiation protection program will be showed. (author). 1 ref

  20. Core ethical values of radiological protection applied to Fukushima case: reflecting common morality and cultural diversities.

    2016-12-01

    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.

    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.

    The aim of this study was to document the current state of administrative structure in US diagnostic radiology (DR) residency program leadership. A secondary objective was to assess for correlation(s), if any, with DR residency programs that equipped positions such as assistant, associate, and emeritus program director (PD) with respect to residency size and region of the country. The Fellowship and Residency Electronic Interactive Database, as well as direct communication and programmatic Web site searches, were used to gather data regarding current US DR residency leadership. Data collected included the presence of additional leadership titles, including assistant PD, associate PD, and PD emeritus, and how many faculty members currently held each position. Programs were excluded if results could not be identified. Analysis of variance and t tests were used to estimate the correlations of the size of a residency with having additional or shared PD positions and the types of positions, respectively. Chi-square tests were used to assess for any regional differences. As of the time of this project, the Fellowship and Residency Electronic Interactive Database defined 186 US DR residency programs. A total of 173 programs (93%) were included in the analysis; the remainder were excluded because of unavailability of relevant data. Seventy-two percent (124 of 173) of programs had additional DR leadership positions. Of these, 30 programs (17%) had more than one such position. There were no significant differences in the sizes of the programs that used these additional positions (mean, 25 ± 12; range, 6-72) compared with those that did not (mean, 24 ± 12; range, 7-51). There were no significant differences between programs that had additional positions with respect to region of the country. The majority of US DR residency programs used some form of additional DR leadership position. In the majority of cases, this was in the form of an assistant or associate PD. Nearly one

    Objective: to investigate the process of learning on human resource management in the radiology residency program at Escola Paulista de Medicina - Universidade Federal de Sao Paulo, aiming at improving radiologists' education. Materials and methods: exploratory study with a quantitative and qualitative approach developed with the faculty staff, preceptors and residents of the program, utilizing a Likert questionnaire (46), taped interviews (18), and categorization based on thematic analysis. Results: According to 71% of the participants, residents have clarity about their role in the development of their activities, and 48% said that residents have no opportunity to learn how to manage their work in a multidisciplinary team. Conclusion: Isolation at medical records room, little interactivity between sectors with diversified and fixed activities, absence of a previous culture and lack of a training program on human resources management may interfere in the development of skills for the residents' practice. There is a need to review objectives of the medical residency in the field of radiology, incorporating, whenever possible, the commitment to the training of skills related to human resources management thus widening the scope of abilities of the future radiologists.

    Lawrence Livermore National Laboratory is redesigning its existing Computer-Based Training (CBT) programs for radiological workers. The redesign represents a major effort that is aimed at producing a single highly interactive and flexible CBT program. The new CBT program is designed to address a variety of radiological workers, including researchers, x-ray operators, and individuals working in tritium, uranium, plutonium, and accelerator facilities. The program addresses the diversity of backgrounds found at a national laboratory. The CBT program includes photographs, line drawings and illustrations, sound, video, and simulations, and it allows for easy insertion and replacement of text, graphics, sound, and video. The new design supports timely updates and customization for use at other University of California sites. The CBT program is divided into ten basic modules. Introduction and Lessons Learned, History and Uses, Fundamentals, Background Radiation, Biological Effects of Radiation, Characteristics of Radionuclides, Radiological Controls, Monitoring, Emergency Response, Responsibilities. Some of the main modules features as many as seven or eight submodules. For example, the module on Characteristics of Radionuclides features submodules on common radionuclides, tritium uranium, plutonium, x-ray machines, E-beam devices, radiographic devices, and accelerators. Required submodules are tailored to an individual's type of work and facility, and they are determined by the answers to an onscreen questionnaire given at the outset of training. Individuals can challenge most individual modules, but certain submodules will be mandatory based on the initial survey. For example, individuals working in the uranium facility will be required to complete the submodule on 'History and Uses of Uranium'. However, all other submodules under the main module, 'History and Uses', will be available if selected for preview. For each module, an opportunity is provided for further

    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.

    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

    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.

    The LCLS-II superconducting electron accelerator at SLAC plans to operate at up to 4 GeV and 240 kW average power, which would create higher radiological impacts particularly near the beam loss points such as beam dumps and halo collimators. The main hazards to the public and environment include direct or skyshine radiation, effluent of radioactive air such as 13N, 15O and 41Ar, and activation of groundwater creating tritium. These hazards were evaluated using analytic methods and FLUKA Monte Carlo code. The controls (mainly extensive bulk shielding and local shielding around high loss points) and monitoring (neutron/photon detectors with detection capabilities below natural background at site boundary, site-wide radioactive air monitors, and groundwater wells) were designed to meet the U.S. DOE and EPA, as well as SLAC requirements. The radiological design and controls for the LCW systems [including concrete housing shielding for 15O and 11C circulating in LCW, 7Be and erosion/corrosion products (22Na, 54Mn, 60Co, 65Zn, etc.) captured in resin and filters, leak detection and containment of LCW with 3H and its waste water discharge; explosion from H2 build-up in surge tank and release of radionuclides] associated with the high power beam dumps are also presented.

    Natural occurring radionuclides are present in many natural resources. Human activities may enhance concentrations of radionuclides and/or enhance potential of exposure to naturally occurring radioactive material (NORM). The industrial residues containing radionuclides have been receiving a considerable global attention, because of the large amounts of NORM containing wastes and the potential long term risks of long-lived radionuclides. Included in this global concern, this work focuses on the characterization of radioactivity in the main residues of Bayer process for alumina production: red mud and sand samples. Usually, the residues of Bayer process are named red mud, in their totality. However, in the industry where the samples were collected, there is an additional residues separation: sand and red mud. The analytical techniques used were gamma spectrometry (HPGe detector) and neutron activation analysis. The concentrations of radionuclides are higher in the red mud than in the sand. These solid residues present activities concentrations enhanced, when compared to bauxite. Further uses for the residues as building material must be more evaluated from the radiological point of view, due to its potential of radiological exposure enhancement, specially caused by radon emission.

    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)
