    2005-01-01

    This paper gives a review of requirements and procedures for the accreditation of test and calibration laboratories in the field of radiation protection, paying particular attention to Croatia. General requirements to be met by a testing or calibration laboratory to be accredited are described in the standard HRN EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories. The quality of a radiation protection programme can only be as good as the quality of the measurements made to support it. Measurement quality can be assured by participation in measurement assurance programmes that evaluate the appropriateness of procedures, facilities, and equipment and include periodic checks to assure adequate performance. These also include internal consistency checks, proficiency tests, intercomparisons and site visits by technical experts to review operations. In Croatia, laboratories are yet to be accredited in the field of radiation protection. However, harmonisation of technical legislation with the EU legal system will require some changes in laws and regulations in the field of radiation protection, including the ones dealing with the notification of testing laboratories and connected procedures. Regarding the notification procedures for testing laboratories in Croatia, in the regulated area, the existing accreditation infrastructure, i.e. Croatian Accreditation Agency is ready for its implementation, as it has already established and further developed a consistent accreditation system, compatible with international requirements and procedures.(author)

  5. Twelve years of cooperation in the field of radiation protection

    2005-06-01

    SSI has pursued an international cooperation program since 1992 within the field of radiation protection and emergency preparedness for radiation accidents with the three Baltic countries as main beneficiaries. As the Baltic countries are members of the EU since May 2004, this bilateral support will now be phased out and replaced with other forms of cooperation. During the years passed, a large number of activities have been launched with a total budget of some 14 million ECU. The Baltic radiation protection authorities have played a big role in the cooperation and Baltic ministries, universities, nuclear technology installations and other industries using radiation have also been engaged in the projects. SKI, SKB, Studsvik and the Swedish nuclear power plants should be mentioned as major cooperation partners on the Swedish side. During autumn 2004 when such a large coordinated work program was coming to an end, SSI decided to hold a seminar with the purpose to follow up experiences from the work and discuss coming forms of cooperation. The seminar took place on the 18 of November 2004 and gathered some 80 participants, 29 of which from the Baltic countries. It was opened by Lars-Erik Holm, the SSI Director General, and the three Baltic countries then presented their views and impressions from the passed years of cooperation. The seminar was concluded with a panel discussion on 'How to proceed from today's situation'. The result was that SSI invited to a new coordination meeting during autumn 2005 to follow up and discuss coordination of radiation protection around the Baltic Sea together with the other Nordic radiation protection authorities.

    1996-01-01

    External radiation fields exposing the human body inhomogenously are not considered neither in radiation protection standards nor in recent ICRU recommendations, but appear frequently in practical radiation protection. A proposal to solve this question is given taking into account both a conceptual and a metrological approach. The proposal suggests that a mean over an area of about 100 cm 2 can be taken as reference area for compliance with limits in terms of effective dose. (author)

    Radiation dose measurement, field of radiobiology, is considered to be critical factor for optimizing radiation protection to the health care practitioners, patients and the public. This lead to equipment that has dose - area product meters permanently installed. In many countries and even institution, the range of equipment is vast and with the opportunity for radiation protection and dose recording varies considerably. Practitioners must move with the changed demands of radiation protection but in many cases without assistance of modern advancements in technology Keeping the three basic safety measures Time, Dose and Shielding we can say 'Optimum dose is safe dose' instead of 'No dose is safe dose'. The purpose enclosed within the title 'Radiation Protection'. The use of radiation is expanding widely everyday around the world and crossing boundaries of medical imaging, diagnostic and. The way to get the ''As low as reasonably achievable' is only achievable by using methodology of radiation protection and to bring the concern of general public and practitioners over the hazards of un-necessary radiation dose. Three basic principles of radiation protection are time, distance and shielding. By minimizing the exposure time increasing the distance and including the shielding we can reduce the optimum range of dose. The ability of shielding material to attenuate radiation is generally given as half value layer. This is the thickness of the material which will reduce the amount of radiation by 50%. Lab coat and gloves must be worn when handling radioactive material or when working in a labeled radiation work area. Safety glasses or other appropriate splash shields should be used when handling radioactive material. 1. Reached to low dose level to occupational workers, public as per prescribed dose limit. 2. By mean of ALARA principle we achieved the protection from radiation besides us using the radiation for our benefit

    In the framework of the EURADOS working group 11, an intercomparison of active neutron survey meters was performed in a pulsed neutron field (PNF). The aim of the exercise was to evaluate the performances of various neutron instruments, including commercially available rem-counters, personal dosemeters and instrument prototypes. The measurements took place at the cyclotron of the Helmholtz-Zentrum Berlin für Materialien und Energie GmbH. The cyclotron is routinely used for proton therapy of ocular tumours, but an experimental area is also available. For the therapy the machine accelerates protons to 68 MeV. The interaction of the proton beam with a thick tungsten target produces a neutron field with energy up to about 60 MeV. One interesting feature of the cyclotron is that the beam can be delivered in bursts, with the possibility to modify in a simple and flexible way the burst length and the ion current. Through this possibility one can obtain radiation bursts of variable duration and intensity. All instruments were placed in a reference position and irradiated with neutrons delivered in bursts of different intensity. The analysis of the instrument response as a function of the burst charge (the total electric charge of the protons in the burst shot onto the tungsten target) permitted to assess for each device the dose underestimation due to the time structure of the radiation field. The personal neutron dosemeters were exposed on a standard PMMA slab phantom and the response linearity was evaluated.

    Education is the base for a successful carrying out of radiation protection measures. Starting from this fact, in the field of biotechnology protection measures should be carried out by biotechnical specialists (veterinarians, agronomists, technologists). In FR Yugoslavia, at the Faculty of Veterinary Medicine a separate course 'Radiobiology and radiation hygiene' was introduced in undergraduate and postgraduate studies m 1976. However, other biotechnological specialists do not study the field of radiation protection separately at their faculties. Because of this, the Expert Group for Radiation Protection in Biotechnology formed at the Federal Ministry of Economy initiated the introducing of a course for this held m undergraduate and postgraduate studies at the faculties of agriculture and technology in FR Yugoslavia. This paper presents the basic elements of the educational plan and program of the course 'Radiobiology and radiation hygiene' for students of biotechnical faculties in FR Yugoslavia and discusses the results obtained until now.

    ISO 8529 consists of the following parts, under the general title Reference neutron radiations: Part 1: Characteristics and methods of production; Part 2: Calibration fundamentals of radiation protection devices related to the basic quantities characterizing the radiation field; Part 3: Calibration of area and personal dosimeters and determination of response as a function of energy and angle of incidence. This Part 2. of ISO 8529 takes as its starting point the neutron sources described in ISO 8529-1. It specifies the procedures to be used for realizing the calibration conditions of radiation protection devices in neutron fields produced by these calibration sources, with particular emphasis on the corrections for extraneous effects (e.g., the neutrons scattered from the walls of the calibration room). In this part of ISO 8529, particular emphasis is placed on calibrations using radionuclide sources (clauses 4 to 6) due to their widespread application, with less details given on the use of accelerator and reactor sources (8.2 and 8.3). This part of ISO 8529 then leads to ISO 8529-3 which gives conversion coefficients and the general rules and procedures for calibration

  13. Standardization of radiation protection measurements in mixed fields of an extended energy range

    International Nuclear Information System (INIS)

    Hoefert, M.; Stevenson, G.R.

    1977-01-01

    The improved ICRU concept of dose equivalent index aims at standardizing both area and personnel dose measurements so that the results on the dosimetry of external irradiations in radiation protection become compatible. It seems that for photon and neutron energies up to 3 and 20 MeV respectively the realization of dose-equivalent index is straightforward, but the inclusion of higher energies and/or other types of radiation will lead both to conceptual and practical difficulties. It will be shown that practical measurements in mixed radiation fields of an extended energy range for protection purposes will overestimate the standardized quantity. While area measurements can be performed to represent a good approximation, greater uncertainties have to be accepted in personnel dosimetry for stray radiation fields around GeV proton accelerators

Risk concepts in radiation protection are described mainly on ICRP: Its history leading to its Publication 1 (1958), Pub. 9 (1965), Pub. 26 (1977) and Pub. 60 (1990). In that recent publication, the term, risk, is used only for the established one like estimated risk or excess relative risk. Risk management of chemicals involves that against pollution from environmental and ecological aspects, and assessment of dioxin and chemicals from toxicology and carcinogenicity aspects. Recently, risks of low dose radiation have been actively discussed conceivably because of possible reduction of the exposure limit in ICRP Recommendation 1990, Chernobyl accident, advances of radiation biology and radiation protection problem in the radioactive waste disposition. Globally, many academic societies such as American Health-Physics Society published Position Statements and Reports and there are activities like the Research program plan for the risk and an international conference of bridging radiation policy and science. Risk concepts involve technological and ecological ones, insurance ones and health ones. Risk assessment or analysis is done through recognition, measurement and prediction, thus through the scientific process based on objective facts. (K.H.)

    Three main pillars underpin the IAEA's mission: Safety and Security - The IAEA helps countries to upgrade their infrastructure for nuclear and radiation safety and security, and to prepare for and respond to emergencies. Work is keyed to international conventions, the development of international standards and the application of these standards. The aim is to protect people and the environment from the harmful effects of exposure to ionizing radiation. Science and Technology - The IAEA is the world's focal point for mobilizing peaceful applications of nuclear science and technology for critical needs in developing countries. The work contributes to alleviating poverty, combating disease and pollution of the environment and to other goals of sustainable development. Safeguards and Verification - The IAEA is the nuclear inspectorate, with more than four decades of verification experience. Inspectors work to verify that nuclear material and activities are not diverted towards military purposes. Quantities and Units: Dose equivalent is the product of absorbed dose of radiation and quality factor (Q). For absorbed dose in rads, dose equivalent is in rems. If absorbed dose is in gray, the dose equivalent is in sievert. Quality factor is defined without reference to any particular biological end point. Quality factors are recommended by committees such as the International Commission on Radiological Protection (ICRP) or the National Council on Radiation Protection and Measurements (NCRP), based on experimental RBE values but with some judgment exercised. Effective Dose Equivalent: It is the sum of the weighted dose equivalents for all irradiated tissues, in which the weighting factors represent the different risks of each tissue to mortality from cancer and hereditary effects. Committed dose equivalent: It is the integral over 50 years of dose equivalent following the intake of a radionuclide. Collective effective dose equivalent: It is a quantity for a population and is

    1997-01-01

    The author have studied tissue-equivalent material with the elemental composition recommended by report No.44 of ICRU. Three different calibration phantoms in shape have been prepared with the tissue-equivalent material in order to study the influence of the angular dependence factor R(d,α) in the radiation field of X-rays on the calibration of individual dose equivalent Hp(d). The requirement of mono-genous radiation field to calibrate several dosimeters on one phantom at the same time can be met by application of dodecahedron phantom, which is difficult on ICRU sphere. Angular dependence factor R(d,α) of 0 degree∼90 degree and conversion coefficients between individual dose equivalent Hp(0.07, α) and the exposure of radiation of different energies and different angles have been established by taking advantage of the dodecahedron. Besides, the authors have studied the variation relation between the individual dose equivalent Hp (10,α) and Hp(0.07,α) in the medical X-rays radiation field

    Two significant events that have taken place this year in the field of radiation protection are reported. New SI units have been proposed (and effectively adopted), and the ICRP has revised its recommendations. Changes of emphasis in the latest recommendations (ICRP Publication 26) imply an altered radiation protection philosophy, in particular the relation of dose limits to estimates of average risk, an altered view of the critical organ approach and a new attitude to genetic dose to the population.

    There are many active protecting methods including Electrostatic Fields, Confined Magnetic Field, Unconfined Magnetic Field and Plasma Shielding etc. for defending the high-energy solar particle events (SPE) and Galactic Cosmic Rays (GCR) in deep space exploration. The concept of using cold plasma to expand a magnetic field is the best one of all possible methods so far. The magnetic field expansion caused by plasma can improve its protective efficiency of space particles. One kind of plasma generator has been developed and installed into the cylindrical permanent magnet in the eccentric. A plasma stream is produced using a helical-shaped antenna driven by a radio-frequency (RF) power supply of 13.56 MHz, which exits from both sides of the magnet and makes the magnetic field expand on one side. The discharging belts phenomenon is similar to the Earth's radiation belt, but the mechanism has yet to be understood. A magnetic probe is used to measure the magnetic field expansion distributions, and the results indicate that the magnetic field intensity increases under higher increments of the discharge power.

    The education of secondary school students in the fields of nuclear sciences was strictly limited according to the 9th recommendations of the ICRP issued in 1966 saying that people under age 18 are not allowed to deal with ionizing radiations. Due to the changes concerning the concept of radiation protection, new opportunities for teaching nuclear technology even in the secondary schools were opened. The 36th recommendations of the ICRP published in 1983 dealing with the maximum permissible doses and the measures taken for radiation protection should be kept in mind while organizing the education of the pupils between age 16 and 18.

    Two situations are studied: the case of stationary gauges where the situation is sure with little actions to do to optimize the radiation protection and the case of mobile sources where the sources can submit to important exposure. In these conditions, the best way to optimize the radiation protection is to integrate the constraints, to put in operation a dosimetry and to keep a correct level of radiation protection information.

  15. Operationalisation of the model 'risk-sovereignty' in the field of radiation protection. Final report

    International Nuclear Information System (INIS)

    Renn, Ortwin; Ruddat, Michael; Sautter, Alexander

    2007-01-01

    The central aim of the BfS research project titled ''operationalization of the 'risk sovereignty model' with special consideration to lifestyle and value approaches as a basis for risk communication in the field of radiation protection'' was the identification of suitable measures to enhance the degree of risk sovereignty of the German population with regard to radiation risks (mobile telephony, nuclear power, ultraviolet radiation and X-rays). This requires the development of a measuring instrument for capturing the prevailing degree of risk sovereignty in the whole population or in certain subgroups with regard to radiation risks empirically. In the first two phases of the project suitable instruments for the construct ''risk sovereignty'' have been developed. Furthermore a value-typology for the identification of different groups of persons as well as independent variables likely to have an influence on 'risk sovereignty' (information behavior, communication or participation intention) were included in the study. The empirical research is divided into a quantitative and a qualitative inquiry. Based on the empirical studies, a guidance document to improve the cognitive capability of people to build up risk sovereignty, in particular in relation to radiation was developed. For the three types of respondents, different strategies were recommended taking into account their needs and information seeking behavior

    After a brief description of the International Organization for Standardization (ISO) and its Technical Committee (TC) 85 ''Nuclear Energy'', the work of its Sub-Committee (SC) 2 ''Radiation Protection'' is described in some detail. Several international standards on subjects closely related to radiation protection have already been published, for example ISO-361 (Basic radiation protection symbol), ISO-1757 (Photographic dosimeters), ISO-1758 and 1759 (Direct and indirect-reading pocket exposure meters), ISO-2889 (Sampling of airborne radioactive materials), ISO-4037 (X and gamma reference radiations for calibration) and ISO-4071 (Testing of exposure meters and dosimeters). TC 85/SC 2 has currently eight active Working Groups (WG) dealing with 14 standards projects, mostly in advanced stages, in such fields as neutron and beta reference radiations, and X and gamma radiations of high and low dose-rates and high energies for calibration purposes, reference radiations for surface contamination apparatus, ejection systems for gamma radiography apparatus, industrial and laboratory irradiators, lead shielding units, protective clothing, thermoluminescence dosemeters, radioelement gauges, and surface contamination and decontamination.

    The usage of beta-radiation sources in various nuclear medicine therapies is increasing. Consequently, enhanced radiation protection measures are required, as medical staff more frequently handle high-activity sources required for therapy. Inhomogeneous radiation fields make it difficult to determine absorbed dose reliably. Routine monitoring with dosemeters does not guarantee any accurate determination of the local skin dose (LSD). In general, correction factors are used to correct for the measured dose and the maximum absorbed dose received. However, strong underestimations of the maximum exposure are possible depending on the individual handling the process and the reliability of dose measurements. Simulations can be used as a tool for a better understanding of the maximum possible exposure depending on the individual-related handling. While measurements reveal the overall dose during the entire irradiation time of the dosemeter, simulations help to analyse sequences of action. Hence, simulations allow for tracking the points of highest absorbed dose received during the handling process. In this respect, simulations were performed using the MCNPX software. In order to investigate the LSD, two hand phantoms were used, a model based on geometrical elements and a voxel hand. A typical situation of radio-synoviorthesis, i.e. handling a syringe filled with 90 Y, was simulated. The results of the simulations show that the annual dose limit may be exceeded within minutes at the position of maximum absorbed dose received and that finger-ring dosemeters measure significantly different doses depending on their wearing position. It is of essential importance to wear the dosemeter properly and to use suitable correction factors with respect to the individual. Simulations are a suitable tool for ensuring reliable dose determination and may help to derive recommendations regarding radiation protection measures. (authors)

  20. Concepts in radiation protection

    International Nuclear Information System (INIS)

    Oncescu, M.

    1996-01-01

    This monograph provides basic notions and principles in dosimetry and radiation protection in compliance with two fundamental works: IAEA Safety Series No.115 - International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources - and Publication no. 60 of International Commission on Radiological Protection. After the review of quantities and units necessary in radiation protection, the book presents the new values of dose limits as well as the values of 'radiation weighting factor', 'tissue weighting factor' and 'conversion factor intake-dose' (committed effective dose per unit intake) by ingestion and inhalation for 30 most important radionuclides. The new values of dose limits, lower than the old values, are a challenge for the radiation protection, especially of the 'public' where the dose limit diminished by a factor of five relative to the earlier edition. The new value of dose limit for public, 1 mSv per year (obviously over the natural exposure of 2.4 mSv per year), imposes new action ways and levels in radiation protection, especially in some cases of exacerbated natural radioactivity. The book provides the calculus of external exposure with the Gamma constant expressed in adequate units, to make the calculation easier. In the calculus of protection shield for gamma sources one uses a method, which while approximate helps save time. The calculus of internal exposure is made using the conversion factor intake-dose. Finally, the 'dosimetric watch' of the natural and artificial radioactivity of the atmosphere, hydrosphere and biosphere is intended to comply with the International Basic Safety Standards. Each chapter ends with a set of illustrative problems which enhances the reader's understanding of underlying concepts and current methods used in the field

    Radiation protection medical care for radiation workers is part of the extensive programme protecting people against dangers emanating from the peaceful application of ionizing radiation. Thus it is a special field of occupational health care and emergency medicine in case of radiation accidents. It has proved helpful in preventing radiation damage as well as in early detection, treatment, after-care, and expert assessment. The medical checks include pre-employment and follow-up examinations, continued long-range medical care as well as specific monitoring of individuals and defined groups of workers. Three levels of action are involved: works medical officers specialized in radiation protection, the Institute of Medicine at the National Board for Atomic Safety and Radiation Protection, and a network of clinical departments specialized in handling cases of acute radiation damage. An account is given of categories, types, and methods of examinations for radiation workers and operators. (author)

    Full text: People are exposed to ionizing radiation in many different forms: cosmic rays that penetrate earth atmosphere or radiation from soil and mineral resources are natural forms of ionizing radiation. Other forms are produced artificially using radioactive materials for various beneficial applications in medicine, industry and other fields. The greatest concerns about ionizing radiation are tied to its potential health effects and a system of radiation protection has been developed to protect people from harmful radiation. The promotion of radiation protection is one of the International Atomic Energy Agency main activities. Radiation protection concerns the protection of workers, members of public, and patients undergoing diagnosis and therapy against the harmful effects of ionizing radiation. The report covers the responsibility of radiation protection officer in Egypt Second Research Reactor (ETRR-2) in Inshas - Egypt, also presents the protection against ionizing radiation from external sources, including types of radiation, sources of radiation (natural - artificial), and measuring units of dose equivalent rate. Also covers the biological effects of ionizing radiation, personal monitoring and radiation survey instruments and safe transport of radioactive materials. The report describes the Egypt Second Research Reactor (ETRR-2), the survey instruments used, also presents the results obtained and gave a relations between different categories of data. (author)

    2001-01-01

    Radiation protection in Bolivia has gone through a number of stages. Initially, in the 1970s, the focus was mainly on the analysis of environmental sources resulting from the nuclear tests carried out by France in the Pacific Ocean. Subsequently, the focus switched somewhat to radiation protection in connection with the mining of uranium and in the area of public health. During the third stage, radiation protection in other areas became important as the use of radiation sources was introduced. Finally, during the present -- fourth -- stage, radiation protection regulations are being introduced and mechanisms for the control of radiation sources are being established. (author)

  5. Enhancing radiation protection

    International Nuclear Information System (INIS)

    2006-01-01

    When a new radiotherapy center in Gezira, Sudan, delivers its first therapeutic dose to a cancer patient, two things happen: A young man begins to regain his health and looks forward to being better able to support his family and contribute to his community; and a developing nation realizes an important step toward deriving the social and economic benefits of nuclear science. The strategic application of nuclear technology in particular fields- human health, industry, food and agriculture, energy, water resources and environmental protection - has enormous potential to help shape the future of developing countries. But past radiological incidents, several of which involved high levels of exposure or death (Bolivia, Brazil, Cost Rica, Georgia, Ghana, Morocco, Panama and Thailand), underscore the inherent and very serious risks. For this reason, the IAEA's Departments of Technical Cooperation and Nuclear Safety and Security partner closely, particularly in the area of radiation protection. They strive to consider every minute detail in the equation that brings together radiation sources, modern technologies, people and the environment. Launched in 1996, the Model Project on Upgrading Radiation Protection Infrastructure (the Model Project) aimed to help Member States: achieve capacities that underpin the safe and secure application of nuclear technologies; establish a legislative framework and regulatory infrastructure; develop exposure control mechanisms to protect workers, medical patients, the public and the environment; and achieve preparedness and planned response to radiological emergencies. In fact, the hospital scenario above typically marks several years of intense collaboration amongst scientists, legislators, regulators, politicians and administrators from both Member States and the IAEA, orchestrated and aided by regional managers and technical experts from the IAEA. As radiation protection team members can attest, every application of nuclear technology

    Persons who are exposed to ionizing radiation at their workplace have to be trained in radiation protection. According to the Radiation Protection Ordinance the person with responsibility in radiation protection has to guarantee that the training is performed twice a year. Our training material was created especially for the persons defined in the Radiation Protection Ordinance and the X-ray Ordinance. It enables persons who teach (generally the radiation protection officer) to perform the training without tedious study and preparation of the documents. Our material is not just another textbook for radiation protection but rather a folder with colour transparencies and explanatory texts which make a difference in volume and price in comparison to other existing materials.

    The new Radiation Protection Act (1988:220) entered into force in Sweden on July 1st, 1988. This book presents the Act as well as certain regulations connected to it. As previously, the main responsibility for public radiation protection will rest with one central radiation protection authority. According to the 1988 Act, the general obligations with regard to radiation protection will place a greater responsibility than in the past on persons carrying out activities involving radiation. Under the act, it is possible to adjust the licensing and supervisory procedures to the level of danger of the radiation source and the need for adequate competence, etc. The Act recognises standardised approval procedures combined with technical regulations for areas where the risks are well known. The Act contains several rules providing for more effective supervision. The supervising authority may in particular decide on the necessary regulations and prohibitions for each individual case. The possibilities of using penal provisions have been extended and a rule on the mandatory execution of orders has been introduced. The Ordinance on Radiation Protection (1988:293) designates the National Institute of Radiation Protection (SSI) as the central authority referred to in the Radiation Protection Act. The book also gives a historic review of radiation protection laws in Sweden, lists regulations issued by SSI and presents explanations of radiation effects and international norms in the area.

    Radiation sources are widely used in medicine, industry, research and education in Madagascar. Safety and security of these sources are the main statutory functions of the Regulatory Authority as defined by the regulations in Radiation Protection in Madagascar. These functions are carried out through the system of notification, authorization and inspection, inventory of radiation source and emergency preparedness. The law no 97-041 on radiation protection and radioactive waste management in Madagascar was promulgated on 2nd January 1998. It governs all activities related to the peaceful use of nuclear energy in Madagascar in order to protect the public, the environment and for the safety of radiation sources. This law complies with the International Basic Safety Standards for protection against ionising Radiation and for the Safety of Radiation Sources (BSS, IAEA Safety Series no 115). Following the promulgation of the law, four decrees have been enacted by the Malagasy Government. With an effective implementation of these decrees, the ANPSR will be the Highest Administrative Authority in the Field of Radiation Protection and Waste Management in Madagascar. This Regulatory Authority is supported by an Executive Secretariat, assisted by the OTR for Radiation Protection and the OCGDR for Managing Radioactive Waste.The paper includes an overview of the regulatory infrastructure and the organizations of radiation protection in Madagascar

  13. Radiation exposure and radiation protection

    International Nuclear Information System (INIS)

    Heuck, F.; Scherer, E.

    1985-01-01

    The present volume is devoted to the radiation hazards and the protective measures which can be taken. It describes the current state of knowledge on the changes which exposure to ionizing rays and other forms of physical energy can induce in organs and tissues, in the functional units and systems of the organism. Special attention is paid to general cellular radiation biology and radiation pathology and to general questions of the biological effects of densely ionizing particle radiation, in order to achieve a better all-round understanding of the effects of radiation on the living organism. Aside from the overviews dealing with the effects of radiation on the abdominal organs, urinary tract, lungs, cerebral and nervous tissue, bones, and skin, the discussion continues with the lymphatic system, the bone marrow as a bloodforming organ, and the various phases of reaction in the reproductive organs, including damage and subsequent regeneration. A special section deals with environmental radiation hazards, including exposure to natural radiation and the dangers of working with radioactive substances, and examines radiation catastrophes from the medical point of view. Not only reactor accidents are covered, but also nuclear explosions, with exhaustive discussion of possible damage and treatment. The state of knowledge on chemical protection against radiation is reviewed in detail. Finally, there is thorough treatment of the mechanism of the substances used for protection against radiation damage in man and of experience concerning this subject to date. In the final section of the book the problems of combined radiotherapy are discussed. The improvement in the efficacy of tumor radiotherapy by means of heavy particles is elucidated, and the significance of the efficacy of tumor therapy using electron-affinitive substances is explained. There is also discussion of the simultaneous use of radiation and pharmaceuticals in the treatment of tumors. (orig./MG) [de

    1981-01-01

    This article first reviews the general radiation protection law at international and national level, with particular reference to the recommendations of the International Commission on Radiological Protection (ICRP) which, although not mandatory, are nevertheless taken into consideration by international organisations establishing basic radiation protection standards such as the UN, IAEA, NEA and Euratom, at Community level, and by national legislation. These standards are therefore remarkably harmonized. Radiation protection rule applied in France for the different activities and uses of radioactive substances are then described, and finally, a description is given of the regulations governing artificial radioisotopes and radioactive effluents.

  2. Notes on free radicals in the field of human and environmental protection against ionizing radiations

    International Nuclear Information System (INIS)

    Bittel, R.

    It is well known that ionizing radiations, in vitro and in vivo produce, free radicals which may be considered as mediators between physical agents and biological targets. Some aspects of this vast problem are accentuated. Ionizing radiations act either directly on the organic molecules of tissues or indirectly by creating, in the surroundings and in tissular water, inorganic free radicals which act on biochemical molecules to gives new radicals. Analysis of the free radical initiation phenomenon in vivo shows that many initiating agents exist, ionizing radiations representing only one group. The role of oxydants, especially oxydising polluants, and the part played by various enzyme systems (super-oxide dismutase, oxydases etc...) are emphasized. After propagation the chain reactions end in combinations between radicals are stopped by certain organic molecules (radical scavengers). Examples are given (free radical formation from compounds of great biological importance: puric and pyrimidic bases, nucleic acids in particular). These aspects are discussed from the viewpoint of their effects on human and environmental protection against both ionizing radiations and certain chemical pollution [fr

    The challenge for planning radiation protection in space is to estimate the risk of events of low probability after low levels of irradiation. This work has revealed many gaps in the present state of knowledge that require further study. Despite investigations of several irradiated populations, the atomic-bomb survivors remain the primary basis for estimating the risk of ionizing radiation. Compared to previous estimates, two new independent evaluations of available information indicate a significantly greater risk of stochastic effects of radiation (cancer and genetic effects) by about a factor of three for radiation workers. This paper presents a brief historical perspective of the international effort to assure radiation protection in space.

  7. From Formal Expertise to Co-expertise: Experience in the Field of Protection against Radiation

    International Nuclear Information System (INIS)

    Lochard, Jacques

    2002-01-01

    As a result of the growing difficulties confronting the heads of public and private high-risk activities, expertise practices have changed radically over the past years in the areas of risk assessment and management. In answer to the erosion of the credibility and legitimacy of traditional 'scientific' expertise, new forms of expertise based on citizen participation have emerged, particularly in fields involving public trust. The author's aim is to analyse the main changes in the field of radiological protection, on the basis of his 25 years of experience in the field. In conclusion, the author discusses the independence of expert assessment, an issue central to the present debate on the organization and practice of expertise in the field of high-risk activities

  8. Optimisation of radiation protection

    International Nuclear Information System (INIS)

    1988-01-01

    Optimisation of radiation protection is one of the key elements in the current radiation protection philosophy. The present system of dose limitation was issued in 1977 by the International Commission on Radiological Protection (ICRP) and includes, in addition to the requirements of justification of practices and limitation of individual doses, the requirement that all exposures be kept as low as is reasonably achievable, taking social and economic factors into account. This last principle is usually referred to as optimisation of radiation protection, or the ALARA principle. The NEA Committee on Radiation Protection and Public Health (CRPPH) organised an ad hoc meeting, in liaison with the NEA committees on the safety of nuclear installations and radioactive waste management. Separate abstracts were prepared for individual papers presented at the meeting

    Some of the major problems in radiation protection are closely connected to issues that have a long, independent tradition in moral philosophy. This contribution focuses on two of these issues. One is the relationship between the protection of individuals and optimisation on the collective level, and the other is the relative valuation of future versus immediate damage. Some of the intellectual tools that have been developed by philosophers can be useful in radiation protection. On the other hand, philosophers have much to learn from radiation protectors, not least when it comes to finding pragmatic solutions to problems that may be intractable in principle

    2002-01-01

    Full text: SUMMARY: The paper describes some of the results of the protection measures in the field of ionizing radiation at FRY border crossings where there were placed stationary monitors of gamma-radiation. The Institute of Security as licensed institution for ionizing radiation detection, designed and placed stationary devices MZ - 100 at border crossings check points named Kelebija, Horgos, Vatin, Gradina, Presevo, Djeneral Jankovic, Batrovci and the ship lock 'Djerdap-I'. CONCLUSION: Over the several years ago IAEA and its member states as well as other international organizations have become increasingly aware of the consequences which might result from illegal activities involving these materials. Therefore initiatives to strengthen physical protection regime are strongly supported and steps towards improving security of nuclear and other radioactive material have already been taken. Yugoslavia as IAEA member state wishes to contribute to the all together efforts in reducing the possibility of illegal activities such as theft, sabotage and trafficking, involving nuclear materials and other radioactive materials, and on the associated proliferation threat and radiation risks. Therefore relevant national bodies prepare project proposal titled 'PREVENTION OF ILLICIT TRAFFICKING IN NUCLEAR AND RADIOACTIVE MATERIALS IN THE FEDERAL REPUBLIC OF YUGOSLAVIA'. Significant work is ahead in this field, since harmonization of radiological control at our border crossings must be achieved. (author)

    The Swedish Government has requested the Swedish Radiation Protection Authority (SSI) to make an account of the authority's role in the field of public health. Radiation Protection consists largely of preventive actions in order to protect man and the environment against harmful effects of radiation. The SSI thus considers most of the authority's activities to be public health related. The report describes a number of radiation protection areas from a health perspective. The measures taken by the authority in these areas are also described along with planned activities. In some areas the authority also points out additional measures.

    2002-01-01

    The software products presented are universally usable programs for radiation protection. The systems were designed in order to establish a comprehensive database specific to radiation protection and, on this basis, model in programs subjects of radiation protection. Development initially focused on the creation of the database. Each software product was to access the same nuclide-specific data; input errors and differences in spelling were to be excluded from the outset. This makes the products more compatible with each other and able to exchange data among each other. The software products are modular in design. Functions recurring in radiation protection are always treated the same way in different programs, and also represented the same way on the program surface. The recognition effect makes it easy for users to familiarize with the products quickly. All software products are written in German and are tailored to the administrative needs and codes and regulations in Germany and in Switzerland. (orig.) [de

    Purpose: To provide radiation protecting clothing materials excellent in mechanical strength, corrosion resistance, flexibility and flexing strength. Constitution: The radiation protecting clothing materials according to this invention has pure lead sheets comprising a thin pure lead foil of 50 to 150 μm and radiation resistant organic materials, for example, polyethylene with high neutron shielding effect disposed to one or both surfaces thereof. The material are excellent in the repeating bending fatigue and mechanical strength, corrosion resistance and flexibility and, accordingly, radiation protecting clothings prepared by using them along or laminating them also possess these excellent characteristics. Further, they are excellent in the handlability, particularly, durability to the repeated holding and extension, as well as are preferable in the physical movability and feeling upon putting. The clothing materials may be cut into an appropriate size, or stitched into clothings made by radiation-resistant materials. In this case, pure lead sheets are used in lamination. (Horiuchi, T.)

    Chapter 21, in describing basic radiation biology and radiation effects, demonstrates the need to have a system of radiation protection that allows the many beneficial uses of radiation to be realized while ensuring detrimental radiation effects are either prevented or minimized. This can be achieved with the twin objectives of preventing the occurrence of deterministic effects and of limiting the probability of stochastic effects to a level that is considered acceptable. In a radiology facility, consideration needs to be given to the patient, the staff involved in performing the radiological procedures, members of the public and other staff that may be in the radiology facility, carers and comforters of patients undergoing procedures, and persons who may be undergoing a radiological procedure as part of a biomedical research project. This chapter discusses how the objectives given above are fulfilled through a system of radiation protection and how such a system should be applied practically in a radiology facility.

  5. Radiation protection zoning

    International Nuclear Information System (INIS)

    2015-01-01

    Radiation being not visible, the zoning of an area containing radioactive sources is important in terms of safety. Concerning radiation protection, 2 work zones are defined by regulations: the monitored zone and the controlled zone. The ministerial order of 15 may 2006 settles the frontier between the 2 zones in terms of radiation dose rates, the rules for access and the safety standards in both zones. Radioprotection rules and the name of the person responsible for radiation protection must be displayed. The frontier between the 2 zones must be materialized and marked with adequate equipment (specific danger signs and tapes). Both zones are submitted to selective entrance, the access for the controlled zone is limited because of the radiation risk and of the necessity of confining radioactive contamination while the limitation of the access to the monitored zone is due to radiation risk only.

  13. Principles of radiation protection

    Energy Technology Data Exchange (ETDEWEB)

    1969-05-15

    In the rapidly developing areas of occupational and public health devoted to the protection of people from both immediate and delayed harmful (and sometimes Irreversible) effects of radiation exposure, industrial hygienists, radiological physicists and radiologists must now assume the additional responsibility of protection against radiation. Everyone during his life will have had one or more X-rays taken for diagnostic purposes. The doses received, depending upon the site, are not harmful to the individual, from the genetic aspect, however, the increasing use of X-ray examinations does present a danger,since almost the whole population is involved. Rapid progress in the development of nuclear energy and the practical extension of its use in medicine, agriculture and industry are steadily increasing the potential danger of large groups of the population being exposed to radiation, and radiation hazards are becoming an important aspect of industrial and public hygiene. WHO is concerned with the overall evaluation of population exposure from peaceful uses of atomic energy and through medical practice, the evaluation of radiation risks,and the control of medical radiation exposure. WHO stimulates and provides technical assistance for the development of appropriate programs of radiation protection with respect to the agricultural, industrial and medical applications of radioisotopes.

    The structure of the existing legislation and its contents and aims are reconsidered. New rules which correspond to the present situation are to be established. Also the fundamental principles of the task and methods of radiation protection are to be changed. The main effort will be to create conditions so that all human beings will be protected against the harmful effects of radiation. The effects on plants, animals and on the environment should be considered as well. The legislation should include both ionizing and non-ionizing radiation. The main responsibility of protection should stay with the central authority. Licensing of apparatus, liability for medical applications and radioactive waste is discussed. Granting of permissions and control should be accomplished by the authority. Cooperation with other national and international authorities is dealt with. (G.B.)

    Switzerland's present radiation protection regulations are based on only two paragraphs of the atomic law but have been very successful in practice. A new radiation protection law, separated from nuclear legislation and valid for all application of ionizing radiation and radioctive materials, was proposed and drafted by the Federal Commission on Radiation Protection and has now been accepted by parliament with only minor modifications. The draft of the revised regulations which also will cover all applications, should be ready for consultations next year. Both the law (which contains principles but no figures such as limits) and the regulations incorporate the latest state of ICRP recommendations and are formulated in such a way as to allow application of or quick adaptation to the new basic ICRP recommendation expected for 1991. The legislation is flexible, with a relatively low regulation density and leaves sufficient room for professional judgement on a case by case basis both for authorities and for the specialists responsible for radiation protection in practice.

  3. Foundations for radiation protection

    International Nuclear Information System (INIS)

    2006-01-01

    Full text; In 1996, the IAEA published the latest edition of the International Basic Safety Standards for Protection Against Ionizing Radiation and for the Safety of Radiation Sources (Basic Safety Standards or BSS) comprising basic requirements to be filled in all activities involving radiation exposure. The standards define internationally harmonized requirements and provide practical guidance for public authorities and services, employers and workers, specialized radiation protection bodies, enterprises and health and safety communities. In the same year, the IAEA, through the technical cooperation programme, launched the Model Project on Upgrading Radiation Protection Infrastructure, a global initiative designed to help Member States establish the infrastructure needed to adhere to the BSS. To address the complexity of this task, the radiation protection team identified key elements, known as Thematic Safety Areas. These are: 1. Legislative Framework and Regulatory Infrastructure, Draft and put into effect radiation protection laws and regulations and establish and empower a national regulatory authority. 2. Occupational Exposure Control Protect the health and safety of each individual who faces the risk of radiation exposure in the workplace through individual and workplace monitoring programmes, including dose assessment, record keeping of doses and quality management. 3. Medical Exposure Control: Develop procedures and activities to control the exposure of patients undergoing diagnosis and/or treatment via diagnostic and interventional radiology, nuclear medicine or radiotherapy through staff training, provision of basic quality control equipment, and the establishment of quality assurance programmes. 4. Public and Environmental Exposure Control: Develop means to protect both the public and the environment including: a) programmes to register, inventory and provide safe storage of unused radioactive sources and material; b) procedures to control and safely

  4. The principles of radiation protection

    International Nuclear Information System (INIS)

    2004-01-01

    The aim of radiation protection is to avoid or to reduce the risks linked to ionizing radiation. In order to reduce these risks, the radiation protection uses three great principles: justification, optimization and limitation of radiation doses. to apply these principles, the radiation protection has regulatory and technical means adapted to three different categories of people: public, patients and workers. The nuclear safety authority elaborates the regulation, and carries out monitoring of the reliable application of radiation protection system. (N.C.)

    CERN Document Server

    AUTHOR|(CDS)2082069; Macián-Juan, Rafael

    Radiation protection calibration facilities are essential to ensure the correct operation of radiation protection instrumentation. Calibrations are performed in specific radiation fields according to the type of instrument to be calibrated: neutrons, photons, X-rays, beta and alpha particles. Some of the instruments are also tested in mixed radiation fields as often encountered close to high-energy particle accelerators. Moreover, calibration facilities are of great importance to evaluate the performance of prototype detectors; testing and measuring the response of a prototype detector to well-known and -characterized radiation fields contributes to improving and optimizing its design and capabilities. The CERN Radiation Protection group is in charge of performing the regular calibrations of all CERN radiation protection devices; these include operational and passive dosimeters, neutron and photon survey-meters, and fixed radiation detectors to monitor the ambient dose equivalent, H*(10), inside CERN accelera...

    Full text: The State of Qatar has become a member State of IAEA since 1974. Later the Department of Industrial Development (DID) beam the focal point and the competent authority regarding all aspects of the peaceful application of Nuclear Technology. In July, 2000 the Supreme Council was established and charged with all matters related to environmental protection. The Supreme Council joined the IAEA Projects on upgrading protection infrastructure in West Asia region. A preliminary research was initiated to discover where radiation sources are being used, and the legal framework, if any, to regulate their use. The research indicated that radiation sources were being used in the industrial practices (well logging, industrial radiography and nuclear gauges) and in medical practices (mainly diagnostic radiology). The research also indicated that there was virtually no legal framework to regulate them. In less than five years, the State of Qatar was able to issue the radiation protection law, three sets of regulations, namely: Radiation Protection Regulations, Radioactive Waste Management Regulations and the Safe Transport of Radioactive Materials Regulations. In addition, several specific regulation work, dose limits and radiation protection officers were issued. A radiation Protection Department, comprising three sections was established. We are providing individual exposure monitoring for most of the radiation workers in the public sector and some in the private sector. We have set up a proper licensing and inspections procedures, where our inspectors are enforcing the law. More recently, we established an early warning network for nuclear of radiological emergencies, consisting of 6 transplantable stations, five mobile stations and two navigating stations. This year, the network was augmented with five fixed station and an advanced early warning centre, which provides early warning via multiple means (MMS, Fax, E-mail and audio alarms).

  12. Precautionary radiation protection

    International Nuclear Information System (INIS)

    Heller, W.

    2006-01-01

    The German federal government annually reports about the development of radioactivity in the environment, providing the most important data and changes in environmental radioactivity and radiation exposure. These reports are based on the Act on Precautionary Protection of the Public against Radiation Exposure (Radiation Protection Provisions Act) of December 19, 1986 as a consequence of the Chernobyl reactor accident. The purpose of the Act is protection of the public from health hazards arising from a nuclear accident or any other event with comparable radiological consequences, and to create the foundations for correct evaluation of the risks resulting from specific radiation exposures. After 1986, the Act was soon given concrete shape by legal ordinances, which made it a workable tool. The following points, among others, can be summarized form the report for 2004: - The calculated natural and manmade overall exposure is 4.0 mSv/a, as in the previous year, and happens to be exactly the same figure as in the report for 1994. - The contribution to radiation exposure by nuclear power plants and other nuclear facilities is less than 0.01 mSv/a. Over a period of nearly twenty years, the Act and the annual reporting regime have proved to work. Standardized criteria prevent data abuse and misinterpretation, respectively. Definitions of limits have contributed to more transparency and more objectivity. (orig.)

    Wachsmann, F.; Consentius, K.

    1981-01-01

    All important subjects of radiation protection are presented in concise form; the explanations may serve as lecture manuscripts. The lectures are divided into 16 to 19 teaching units. Each teaching unit is supplemented by a slide to be projected on a screen while the text is read. This method of visual teaching has already been tried with good results in medicine and medical engineering. Pictures of the slides are given in the text so that the book may also be used for self-studies. The main facts are summarized at the end of each lesson. The finished book will consist of 8 lessons; the first three of these discuss 1. Radiation effects and hazards 2. Dose definitions and units and their role in radiology and radiation protection 3. Dose limits and legal specifications. (orig.) [de

    The commentary is intended to contribute to protection of the population by a practice-oriented discussion and explanation of questions arising in connection with the Preventive Radiation Protection Act. Leaving aside discussions about abandonment of nuclear power, or criticism from any legal point of view, the commentary adopts the practical approach that accepts, and tries to help implementing, the act as it is. It is a guide for readers who are not experts in the law and gives a line of orientation by means of explanations and sometimes by citations from other acts (in footnotes). The commentary also presents the EURATOM Directive No. 3954/87 dated 22 December 1987, the EC Directive No. 3955/87 dated 22 December 1987, and the EC Directive No. 1983/88 dated 5 July 1988.

    In the last decade, four platforms on radiation protection issues have been created in Europe: ALLIANCE (radioecology), EURADOS (dosimetry), MELODI (effects of low dose) and NERIS (emergency preparedness and management). The work done in close collaboration within the platforms is contributing to the sustainability of the RTD activities in radiation protection. The platforms have developed Strategic Research Agendas, defining long-term research priorities in their respective disciplines. The ultimate goal is to develop a joint Strategic Research Agenda for radiation protection in Europe.

    As a federal research Centre, SCK-CEN has the statutory assignment to give priority to research related to safety, radioactive waste management, protection of man and environment, management of fissile and other strategic materials and social implications as part of the pursuit of sustainable development and to develop and gather the necessary knowledge and spread this knowledge through formation and communication. At the Division of Radiation Protection at SCK-CEN we are therefore active to maintain and enhance knowledge and expertise in each aspect of radiation protection: we study the risk of exposure - the way that radioactive materials spread in the environment and the potential for human contact - and the risk from exposure - how radiation affects human health; we perform health physics measurements; we are involved in emergency planning and preparedness and support to risk governance and decision taking. These activities are supported by radiation specific analysis and measurement techniques. These activities are not performed in isolation but in context of national and international collaborations or demands

    For protection purposes, the biological effects of radiation are separated into stochastic effects (cancer, hereditary effects) presumed to be unicellular in origin, and tissue reactions due to injury in populations of cells. The latter are deterministic effects, renamed ‘tissue reactions’ in the 2007 Recommendations of the International Commission on Radiological Protection because of the increasing evidence of the ability to modify responses after irradiation. Tissue reactions become manifest either early or late after doses above a threshold dose, which is the basis for recommended dose limits for avoiding such effects. Latency time before manifestation is related to cell turnover rates, and tissue proliferative and structural organisation. Threshold doses have been defined for practical purposes at 1% incidence of an effect. In general, threshold doses are lower for longer follow-up times because of the slow progression of injury before manifestation. Radiosensitive individuals in the population may contribute to low threshold doses, and in the future, threshold doses may be increased by the use of various biological response modifiers post irradiation for reducing injury. Threshold doses would be expected to be higher for fractionated or protracted doses, unless doses below the threshold dose only cause single-hit-type events that are not modified by repair/recovery phenomena, or if different mechanisms of injury are involved at low and high doses.

    Regulatory requirements for radiation protection have evolved and matured over several decades. Due to the wide adoption of recommendations of the International Commission on Radiation Protection (ICRP), there exists international agreement on the principles to be followed for radiation protection. This foundation will be increasingly important due to the growing need for international agreements and standards for radiation protection and radioactive materials management. During the infancy of the commercial nuclear industry, primary reliance was placed on the protection of the individual, both in the work force and as a member of the public. With the growth of nuclear power in the 1960's and 1970's, environmental impact assessments and expert reviews of bio-effects data have focused attention on statistical risks to large population groups and the use of the collective dose commitment concept to estimate potential effects. The potential release of long-lived radionuclides from the nuclear fuel cycle requires further consideration of radionuclide accumulation in the biosphere and calls for controls conceived and implemented at the international level. The initial development efforts for addressing these concerns already have been instituted by the ICRP and the IAEA. However, formal international agreements and a unified set of international standards may be required to implement the recommendations of these groups. Further international efforts in the field of radiation protection are also called for in developing waste management practices and radioactive effluent control technology, in site selection for fuel reprocessing plants and waste dispersal facilities, and for ensuring safe transport of high-level wastes in various forms. Since the regulation of very low dose rates and doses will be involved, it will be useful to reexamine dose-effect relationships and societal goals for health protection.

    A brief report is given of a paper presented at the symposium on 'Radiation and the Worker - where do we go from here' in London 1983. The paper concerned the employers' viewpoint on the draft of the proposed Ionising Radiations Regulations in the Health and Safety Commission Consultative Document. It was concluded that there was already a very good standard of radiological protection in the UK and that any improvements could therefore only be fringe improvements, although the cost to the employer of introducing and implementing the new proposed Regulations was bound to be high.

    The exposures anticipated for astronauts in the anticipated human exploration and development of space will be significantly higher (both annual and carrier) than for any other occupational group. In addition, the exposures in deep space result largely from galactic cosmic rays for which there is as yet little experience. Some evidence exists indicating that conventional linear energy transfer defined protection quantities (quality factors) may not be appropriate. The authors evaluate their current understanding of radiation protection with laboratory and flight experimental data and discuss recent improvements in interaction models and transport methods

    According to the Radiation Protection Ordinance, radiation protection experts directing or supervising the handling of radioactive materials must have expert knowledge. The concept of expert knowledge has been clearly defined by the Fachverband e.V. in a catalogue of instruction goals. The manual follows the principles of this catalogue; it presents the expert knowledge required in a total of 15 subject groups. There is an index which helps the reader to find his specific subject group and the knowledge required of him in this subject group. However, the manual gives only an outline of the subject matter in many instances and should therefore not be regarded as a textbook in the proper sense. (orig./HP) [de

  4. Emerging radiation protection

    International Nuclear Information System (INIS)

    Allard, D.J.

    1993-01-01

    In recent years, a number of radiation protection issues have emerged into the public forum. The perceived high risks associated with radiation exposure, and disproportionate media attention to such issues, have contributed to heightened concerns by the public and the individual occupationally exposed worker. This paper examines the new and controversial radiation risk estimates of the National Research Council's BEIR V committee, which are based on the most current atomic-bomb survivor data and a revised dosimetry model. These risk estimates are somewhat higher than past values, and may eventually impact the legal framework in the United States through the regulations of the EPA, NRC, DOE, OSHA, and other agencies that set radiation exposure standards. Additionally, present regulations and standards are often based upon differing levels of acceptable risk, which have led to conflicting exposure and effluent release criteria. Further, due to inherent boundaries in legal authority, many potentially significant sources of radiation exposure to the public remain unregulated Radiation exposure scenarios such as medical x-ray, radon, and other technology enhanced sources have no legal limits. These issues and others are examined and analyzed with respect to regulatory policy

  5. Radiation protection: A correction

    An error in translation inadvertently distorted the sense of a paragraph in the article entitled 'Ecological Aspects of Radiation Protection', by Dr. P. Recht, which appeared in the Bulletin, Volume 14, No. 2 earlier this year. In the English text the error appears on Page 28, second paragraph, which reads, as published: 'An instance familiar to radiation protection specialists, which has since come to be regarded as a classic illustration of this approach, is the accidental release at the Windscale nuclear centre in the north of England.' In the French original of this text no reference was made, or intended, to the accidental release which took place in 1957; the reference was to the study of the critical population group exposed to routine releases from the centre, as the footnote made clear. A more correct translation of the relevant sentence reads: 'A classic example of this approach, well-known to radiation protection specialists, is that of releases from the Windscale nuclear centre, in the north of England.' A second error appeared in the footnote already referred to. In all languages, the critical population group studied in respect of the Windscale releases is named as that of Cornwall; the reference should be, of course, to that part of the population of Wales who eat laver bread.

    1977-01-01

    The German Standards Institute (DIN Deutsches Institut fuer Normung, Berlin) is engaged in health physics standards development in the following committees. The Nuclear Standards Committee (NKe), which deals mainly with nuclear science and technology, the fuel cycle, and radiation protection techniques. The Radiology Standards Committee (FNR), whose responsibilities are traditionally the principles of radiation protection and dosimetry, applied medical dosimetry, and medical health physics. The German Electrotechnical Commission (DKE), which is concerned mostly with instrumentation standards. The Material Testing Committee (FNM), which is responsible for radiation protection in nonmedical radiography. The current body of over one hundred standards and draft standards was established to supplement the Federal German radiation protection legislation, because voluntary standards can deal in more detail with the specific practical problems. The number of standards is steadily expanding due to the vigorous efforts of about thirty working groups, consisting of essentially all leading German experts of this field. Work is supported by the industry and the Federal Government. A review of the present status and future plans, and of the international aspects with regard to European and world (ISO, etc.) standards will be presented

    Written by two eminent expects in the field with many years of teaching experience between them, this book presents a concise coverage of the physical and biological basics of radiation biology and protection. The book begins with a description of the methods of particle detection and dosimetric evaluation. The effects of ionizing radiation on man are treated from the initial physico-chemical phase of interaction to their conceivable pathological consequences. Regulations, limits and safeguards on nuclear power plants, radioisotope installations and medical centers which make use of ionizing radiation are given and the risks of exposure to natural, industrial and scientific radiation sources evaluated. The final chapter takes a look at some of the more important nuclear accidents, including Windscale, Three Mile Island, and Chernobyl, and describes basic procedures to be carried out in the eventuality of a nuclear emergency. Twelve chapters have been processed separately for inclusion in the appropriate data bases

    An assessment of the present situation concerning centres of competence in the fields of Nuclear Fission and Radiation Protection has been carried out with the intention to draw strategic conclusions as regards further needs in these fields, based on the actual situation and perceived future developments. This study was initiated by the programme committee for the Euratom research and training programme in the field of Nuclear Energy (1998 - 2002). To carry out this exercise, a Panel of four independent experts had been set up. The Panel had prepared a questionnaire comprising a comprehensive set of questions aiming at the acquisition of the information needed to carry out the assessment exercise. The questionnaire consisted in ten different form sheets and had been put on the Internet in order to ease the access and offer a comfortable way of filling in the form sheets. Out of 420 organisations invited to participate in the exercise, 293 organisations from EU member states, Central and Eastern European Accession Countries (CEEC) and from Norway and Switzerland, had responded and registered for participation. Finally, 218 organisations have participated in the exercise. In spite of all efforts undertaken, several known main European nuclear research actors from different European countries have not participated in the exercise. (orig.)

    The European Commission has funded within its 6th Framework Programme a three-year project (2005–2007) called CONRAD, COordinated Network for RAdiation Dosimetry. The organizational framework for this project was provided by the European radiation Dosimetry Group EURADOS. Work Package 6 of CONRAD dealt with “complex mixed radiation fields at workplaces” and in this context it organised a benchmark exercise, which included both measurements and calculations, in a stray radiation field at a high-energy particle accelerator at GSI, Germany. The aim was to intercompare the response of several types of active detectors and passive dosemeters in a well-characterised workplace field. The Monte Carlo simulations of the radiation field and the experimental determination of the neutron spectra with various Bonner Sphere Spectrometers are discussed in Rollet et al.

    The safety, the quality and efficiency of the radiological monitoring systems for block one and two of the NPP Mochovce, designed and delivered by the general designer, should be increased by EUCOM Siemens. Modern, accident resistant and/or more powerful monitoring systems have been designed by Siemens will be added to the existing systems. To achieve this radiation measuring units will be installed inside the hermetic zone, in the reactor hall, at the stack, at the release water system and in the environment in the vicinity of the NPP. The presentation, the storage distribution and the processing of all measuring results also will be optimised by installing a modern high-performance computer system, the so-called Central Radiological Computer System 'CRCS', featuring a high availability. The components will be installed in the relevant control rooms all over the plant. With this computer system it is easy to control the radiation level inside and outside the NPP during normal operation and during and after an accident. Special programs, developed by Siemens support the staff by interpreting the consequences of radioactive releases into the environment and by initiating protection procedures during and after an accident. All functions of the system are available for emergency protection drills and training the staff interruption of the normal control procedure. For the personal protection a digital personal dosimetry system completely considering with the requirements of ICRP 60 and several contamination monitors will be installed. (authors)

    This paper describes the work of the Commission of the European Communties in training and information in radiation protection. Nowadays nuclear science and technology have many applications ranging far beyond nuclear power and medical X-rays to include inter alia conventional industry, agriculture and research. This means that the need for radiation protection of workers has become correspondingly more widespread, as has concern for the general public and the environment - not only in the case of a nuclear accident - but also, at a more mundane level, ongoing health protection of the public, for example by monitoring radioactive emissions from nuclear installations in routine operation. While this has led in turn to a major expansion of work in the many facets of radiation protection the review will be restricted to the Radiation Protection Division's activities in training and information. However, it should be remembered that all workers are firstly members of the public and more general aspects are also considered not just those concerning workers in radiation-related occupation.

    In Australia, public exposure to ionizing radiation above background is considered to be negligible. Average occupational exposures are about 0.5 millisievert per year, although there are some specialized industries and professions where they are much higher. The National Health and Medical Research Council has therefore adopted a position similar to that of the International Commission on Radiological Protection. For the moment, no revision of exposure limits is recommended, but users are remined of their responsibility to ensure that exposures are kept low, particularly in those workplaces where significant exposures take place

  10. Units for radiation protection work

    ICRU has defined special measurable (operational) quantities for radiation protection. A consequence of using the operational quantities is that hand-held and personal dosemeters can give different measuring results in the same radiation situation. The differences vary and are caused by the geometry of the radiation field. The units have well documented relations to e.g. the ICRP effective dose and equivalent dose to an organ or tissue. Therefore, it is possible to estimate these doses from a measured value of e.g. the ambient dose equivalent. ICRU and ICRP have recently reviewed these relations in two important commonly issued reports (Report 57 and Publication 74). This report tries to show the value of understanding these units and their relations and is primarily meant to be used for educational purposes. 11 refs

  11. Radiation protection for human spaceflight

    2009-01-01

    Cosmic radiation exposure is one of the most significant risks associated with human space exploration. Except for the principles of justification and optimization (ALARA), the concepts of terrestrial radiation protection are of limited applicability to human spaceflight, as until now only few experimentally verified data on the biological effectiveness of heavy ions and the dose distribution within the human body exist. Instead of applying the annual dose limits for workers on ground also to astronauts, whose careers are of comparatively short duration, the overall lifetime risk is used as a measure. For long-term missions outside Earth's magnetic field, the acceptable level of risk has not yet been defined, since there is not enough information available to estimate the risk of effects to the central nervous system and of potential non-cancer radiation health hazards.

    According to the new Croatian Act on ionizing radiation protection which is in a final stage of genesis, Ministry of Health of the Republic of Croatia is the governmental body responsible for all aspects relating sources of ionizing radiation in Croatia: practices, licenses, users, transport, in medicine and industry as well, workers with sources of ionizing radiation, emergency preparedness in radiological accidents, storage of radioactive wastes, x-ray machines and other machines producing ionizing radiation and radioactive materials in the environment. Ministry of Health is responsible to the Government of the Republic of Croatia, closely collaborating with the Croatian Radiation Protection Institute, health institution for the performance of scientific and investigation activities in the field of radiation protection. Ministry of Health is also working together with the Croatian Institute for the Occupational Health. More emphasis has been laid on recent discussion among the world leading radiation protection experts on justification of the last recommendations of the ICRP 60 publication. (author)

  14. Space radiation protection: Destination Mars.

    Durante, Marco

    2014-04-01

    National space agencies are planning a human mission to Mars in the XXI century. Space radiation is generally acknowledged as a potential showstopper for this mission for two reasons: a) high uncertainty on the risk of radiation-induced morbidity, and b) lack of simple countermeasures to reduce the exposure. The need for radiation exposure mitigation tools in a mission to Mars is supported by the recent measurements of the radiation field on the Mars Science Laboratory. Shielding is the simplest physical countermeasure, but the current materials provide poor reduction of the dose deposited by high-energy cosmic rays. Accelerator-based tests of new materials can be used to assess additional protection in the spacecraft. Active shielding is very promising, but as yet not applicable in practical cases. Several studies are developing technologies based on superconducting magnetic fields in space. Reducing the transit time to Mars is arguably the best solution but novel nuclear thermal-electric propulsion systems also seem to be far from practical realization. It is likely that the first mission to Mars will employ a combination of these options to reduce radiation exposure. Copyright © 2014 The Committee on Space Research (COSPAR).

    To provide an inspiring working environment for young students and scientists, it is important that they at an early stage can take part in a network of scientists working in their fields of interest. However, within each of the five Nordic countries the network of people involved in the fields of radiophysics, radiochemistry, radioecology, radiation protection and other related fields is rather small. Educational networking is a key factor in keeping young researchers motivated to continue working within these fields, and to recruit new students. For that reason the first YoungRad-seminar was held in Helsinki 14-15 December 2006. 43 young participants including MSc and PhD students at universities, researchers at different institutes and personnel from Nordic authorities took part in the seminar. All Nordic countries except Iceland were represented. The seminar was divided into four sessions including oral and poster presentations. In addition two senior researchers were invited to speak about Nordic radioecology and NKS. This report contains the abstracts and presentations made at the seminar. (au)

  19. What is good radiation protection?

    International Nuclear Information System (INIS)

    Lorenz, B.

    2016-01-01

    Radiation protection is based on the ICRP-System with its pillars justification, limitation and optimization. From this radiation protection should be the same irrespective of the application of radiation. But radiation protection in the nuclear industry is much different from the use of radiation sources or X-ray units. This is by far not due to the different technologies. It originates from the different interpretation of the system. For one person good radiation protection would mean to have no radiation exposures, to avoid radiation at all as best option and to use it only if there are no alternatives. For another person the best radiation protection would be the one which does not produce much efforts and costs. So what is reasonable? In reality the first interpretation prevails, at least in Germany. A change is needed. If we continue to exercise radiation protection as we do it today the beneficial application of radiation will be restricted unduly and might become impossible at all. A stronger orientation towards the naturally occurring radiation would help instead to regulate natural radiation in the same way as it is done for artificial radiation. The system of ICRP has to be changed fundamentally.

  20. Pregnancy and Radiation Protection

    Several modalities are currently utilized for diagnosis and therapy, by appropriate application of x-rays. In diagnostic radiology, interventional radiology, radiotherapy, interventional cardiology, nuclear medicine and other specialties radiation protection of a pregnant woman as a patient, as well as a member of the operating personnel, is of outmost importance. Based on radiation risk, the termination of pregnancy is not justified if foetal doses are below 100 mGy. For foetal doses between 100 and 500 mGy, a decision is reached on a case by case basis. In Diagnostic Radiology, when a pregnant patient takes an abdomen CT, then an estimation of the foetus' dose is necessary. However, it is extremely rare for the dose to be high enough to justify an abortion. Radiographs of the chest and extremities can be done at any period of pregnancy, provided that the equipment is functioning properly. Usually, the radiation risk is lower than the risk of not undergoing a radiological examination. Radiation exposure in uterus from diagnostic radiological examinations is unlikely to result in any deleterious effect on the child, but the possibility of a radiation-induced effect can not be entirely ruled out. The effects of exposure to radiation on the foetus depend on the time of exposure, the date of conception and the absorbed dose. Finally, a pregnant worker can continue working in an x-ray department, as long as there is reasonable assurance that the foetal dose can be kept below 1 mGy during the pregnancy. Nuclear Medicine diagnostic examinations using short-lived radionuclides can be used for pregnant patient. Irradiation of the foetus results from placental transfer and distribution of radiopharmaceuticals in the foetal tissues, as well as from external irradiation from radioactivity in the mother's organ and tissues. As a rule, a pregnant patient should not undergo therapy with radionuclide, unless it is crucial for her life. In Radiotherapy, the patient, treating

  1. Radiation protection and society

    The radiological protection of population, living on the contaminated territories, is actual 10 years after the Chernobyl accident. Eventually, the whole system of countermeasures application is aimed to protect society as a complex community of individuals . The variety of levels of society, i.e. family, settlement on the whole, can be considered as certain harmonic systems differing in their public consciousness levels and lifestyles, this explain the difference in their 'behaviour' in terms of radiation protection and attitude to the information obtained. Each level of society possesses a certain degree of liberty of choice, that finally influence the magnitude and the character of dose distribution within certain population groups. In general, the dose distribution in the settlement can be explained only on the bases of 'family' analysis. This concerns the rural settlement as a society too. All rural settlement can be divided into two or three classes: with low, high and intermediate social features. Small settlements (< 100 persons), where the advanced in age persons with low material income and high degree of natural economy are applied to the first class. This results in higher doses (2-3 fold), than in the settlements with higher social level. The analysis shows that in socially 'waning' settlements the countermeasures are less efficient and the term of their action is shorter. (this class is the largest, About 50% among all the rural settlements). Due to the deterioration of the economic situation in the Republic of Belarus after 1991-1992 resulted in the increase of doses mainly in the habitants first of all of this class of settlements. It seems problematic to increase countermeasures efficiency in this class of settlements without the refuse of the accustomed lifestyle and radical improvement of social-demographic and economic conditions. The present material shows the necessity of the differential approach based on 'society-analysis' in the

    2008-01-01

    The paper intends to present the evolution and actual situation of radiation protection and safety infrastructure in Albania, focusing in its establishing and functioning in accordance with BBS and other important documents of specialized international organizations. There are described the legal framework of radiation safety, the regulatory authority, the services as well the practice of their functioning. The issue of the establishing and functioning of the radiation safety infrastructure in Albania was considered as a prerequisite for a good practices development in the peaceful uses of radiation sources . The existence of the adequate legislation and the regulatory authority, functioning based in the Basic Safety Standards (BSS), are the necessary condition providing the fulfilment of the most important issues in the mentioned field. The first document on radiation protection in Albania stated that 'for the safe use of radiation sources it is mandatory that the legal person should have a valid permission issued by Radiation Protection Commission'. A special organ was established in the Ministry of Health to supervise providing of the radiation protection measures. This organization of radiation protection showed many lacks as result of the low efficiency . The personnel monitoring, import, transport, waste management and training of workers were in charge of Institute of Nuclear Physics (INP). In 1992 an IAEA RAPAT mission visited Albania and proposed some recommendations for radiation protection improvements. The mission concluded that 'the legislation of the radiation protection should be developed'. In 1995 Albania was involved in the IAEA Model Project 'Upgrading of Radiation Protection Infrastructure'. This project, which is still in course, intended to establish the modern radiation safety infrastructures in the countries with low efficiency ones and to update and upgrade all aspects related with radiation safety: legislation and regulations, regulatory

    1969-01-01

    The recommendations of the ICRP and the NCRP were developed primarily for occupational radiation exposures. They were later modified and applied to non-occupational exposures of populations. These, with appropriate interpretations, can be used to provide Plowshare radiation protection guidance. Exposures from Plowshare operations will tend to be acute, arising from radionuclides of relatively short half-life, but will have some chronic aspects due to small amounts of long-lived radionuclides generated. In addition, the neutron activation process of Plowshare technology will produce radionuclides not commonly encountered in routine nuclear energy programs. How these radionuclides contribute to personnel exposure is known for only a few situations that may not be representative of Plowshare exposure. Further complications arise from differences in radionuclide deposition and physiological sensitivity among individuals of different ages and states of health in the exposed population. All parameters necessary to evaluate such exposures are not available, even for good quantitative approximations, resulting in the need for interpretive experience. (author)

    In the field of radiation protection all hitherto used units for activity, activity concentrations, exposure, absorbed dose, and dose rates have to be replaced by SI units during the next years. For this purpose graphs and conversion tables are given as well as recommendations on unit combinations preferentially to be used. As to the dose equivalent, it is suggested to introduce a new special unit being 100 times greater than the rem, instead of maintaining the rem or using the gray for both absorbed dose and dose equivalent. Measures and time schedule relating to the gradual transition to SI units in measuring techniques, training, and publishing et cetera are explained. (author)

    This 'radiation protection primer' does not pretend to give absolute, final answers to the many questions that have been arising after the Chernobyl accident. What it is intended to supply, as a schematic overview of problems resulting from nuclear accidents, and a likewise systematic outline of possible solutions and sensible reactions to such an event. The book takes up questions such as: What has happened to the soil. Will future harvests be 'clean' again. What does radioactivity to our drinking water and other waters. What are the effects of a radioactive fallout on food. What may we eat or drink. What happens to the human body after intake of radioactive air, or - even only slightly - contaminated food or water. What can we do to protect our health, and the health of our children. Is there anything else we can do in order to avoid such a disaster in future, except from shutting-off all reactors. The book itself presents some answers and advice, along with a list of terms and explanations, and addresses to apply to for further advice and information. (orig./HP) [de

    The present invention concerns radiation protective clothings suitable for medical protective clothings, aprons, etc. A primary sheet comprises a lead-incorporated organic polymer layer having a less frictional layer on one side and a contamination-resistant layer on the other side. A secondary sheet comprises a lead-incorporated organic polymer layer having a less frictional layer on one side and a comfortable skin-feeling layer on the other side. The less frictional layers of the primary and the secondary layer are laminated so as to be in contact with each other. Then, they are formed so that the comfortable skin-feeling layer of the secondary sheet is on the inner side, in other words, on the side of a wearer, and the contamination-resistant layer of the primary sheet is on the outer side. With such a constitution, although it involves the lead-incorporated organic polymer sheets of a large weight, it is comfortable to wear because of excellent flexibility and causes less feeling of fatigue even during wearing for a long period of time.

  17. Occupational radiation protection. Safety guide

    International Nuclear Information System (INIS)

    2002-01-01

    Occupational exposure to ionizing radiation can occur in a range of industries, medical institutions, educational and research establishments and nuclear fuel cycle facilities. Adequate radiation protection of workers is essential for the safe and acceptable use of radiation, radioactive materials and nuclear energy. In 1996, the Agency published Safety Fundamentals on Radiation Protection and the Safety of Radiation Sources (IAEA Safety Series No. 120) and International Basic Safety Standards for Protection against Ionizing, Radiation and for the Safety of Radiation Sources (IAEA Safety Series No. 115), both of which were jointly sponsored by the Food and Agriculture Organization of the United Nations, the IAEA, the International Labour Organisation, the OECD Nuclear Energy Agency, the Pan American Health Organization and the World Health Organization.

    Occupational exposure to ionizing radiation can occur in a range of industries, medical institutions, educational and research establishments and nuclear fuel cycle facilities. Adequate radiation protection of workers is essential for the safe and acceptable use of radiation, radioactive materials and nuclear energy.

    In Malaysia, the need for maintaining competency in radiation protection is emerging, focusing on the qualification of Radiation Protection Officers (RPO). Regulation 23 of Malaysian Radiation Protection (Basic Safety Standards) Regulations 1988, requires the applicant to employ an RPO, with the necessary knowledge, skill and training, enabling effective protection of individuals and minimizing danger to life, property and the environment for all activities sought to be licensed. An RPO must demonstrate the knowledge required, by attending RPO courses organised by an accredited agency and pass the RPO certification examination. Maintaining a high level of competency is crucial for future development of safe applications of ionising radiation. The major goal of training is to provide essential knowledge and skills and to foster correct attitudes on radiation protection and safe use of radiation sources. Assessment of the competency is through theoretical and practical examination. A standard criterion on the performance of the individuals evaluated has been established and only those who meet this criterion can be accepted as certified RPO. The National Committee for the Certification of Radiation Protection Officer (NCCRPO), comprising experts in various fields, is responsible to review and update requirements on competency of a certified RPO. With increasing number of candidates (i.e. 701 in 2008) and the international requirement for radioactive source security, it is incumbent upon the NCCRPO to improve the syllabus of the certification scheme. The introduction of a Radiation Protection Advisor (RPA) to provide service and advice to the radiation industry in Malaysia is also seriously considered. (author)

    The European Commission has funded within its 6th Framework Programme a three-year project (2005-2007) called CONRAD, COordinated Network for RAdiation Dosimetry. The organizational framework for this project was provided by the European radiation Dosimetry Group EURADOS. Work Package 6 of CONRAD dealt with 'complex mixed radiation fields at workplaces' and in this context it organised a benchmark exercise, which included both measurements and calculations, in a stray radiation field at a high-energy particle accelerator at GSI, Germany. The aim was to intercompare the response of several types of active detectors and passive dosemeters in a well-characterised workplace field. The Monte Carlo simulations of the radiation field and the experimental determination of the neutron spectra with various Bonner Sphere Spectrometers are discussed in Rollet et al. (2008) and in Wiegel et al. (2008). This paper focuses on the intercomparison of the response of the dosemeters in terms of ambient dose equivalent. The paper describes in detail the detectors employed in the experiment, followed by a discussion of the results. A comparison is also made with the H*(10) values predicted by the Monte Carlo simulations and those measured by the BSS systems.

    Some data are cited from Japanese statistics analyzing the genetic injuries stemming from the nuclear explosion in Hiroshima. It is shown that neither the number of the unsuccesful pregnancies nor the mortality of the born offsprings increased in those cases there the mother or the father had been exposed to 1-100 rad radiation. There was no significant difference in the chromosomal aberrations amoung the children of irradiated and control parents. (L.E.)

    Radiation Protection Training is an important component of Radiation Protection and serves for human radiation safety. According to the Lithuanian Law on Radiation Protection the legal persons and enterprises without the status of legal persons to conduct practices with sources or which workers work under exposure must organize at their own expenses a compulsory training and assessment of knowledge of the workers engaging in activities with the sources and radiation protection officers. Such training has been started in 1999. In Lithuania there are few institutions executing Radiation Protection training. Under requirements of legal act On Frequency and Procedure of Compulsory Training and Assessment Knowledge of the Workers Engage in Activities with the Sources of Ionising Radiation and Radiation Protection Officers these institutions have to prepare and coordinate training programs with the Radiation Protection Center. There are adopted different educating programs for Radiation Protection Training to the Workers and Radiation Protection Officers depending on character of work and danger of sources. The duration of Training is from 30 to 270 hours. The Training shall be renewed every five years passing 30 hors course. To ensure the adequate quality of training a great deal of attention is paid to qualifying the lectures. For this purpose, it was established an Evaluation commission to estimate the adequacy of lecturer's knowledge to requirements of Training programs. After passing exams the lectures get the qualification confirming certificates. The main task of our days is to establish and arrange the National Training Centre on Radiation Protection Training that would satisfy requirements and recommendations of legal documents of IAEA and EU for such kind of institutions of institutions.

    The system of dose limitation and present guidance for emergency workers and guidance for intervention on behalf of the public are discussed. There are three elements for the system of dose limitation: justification, optimization and dose limits. The first element is basically a political process in this country. Justification is based on a risk-benefit analysis, and justification of the use of radioactive materials or radiation is generally not within the authority of radiation protection managers. Radiation protection managers typically assess detriments or harm caused by radiation exposure and have very little expertise in assessing the benefits of a particular practice involving nuclear material

    The justification of the practices is the fundamental principle on which rests the peaceful use of ionizing radiations. They actually contain as aspirations to improve the quality of people's lives, contributing to sustainable development through environmental protection, so that the sources security and the individuals protection will be conditions which are not and should can not be operated. For medical applications is a highly illustrative example of this, since both for the diagnosis and therapy, the goal is to achieve what is sought for the white tissue, secured the least possible damage to the neighboring tissues so that in turn reduce the negative effects for the patient. As a basis for achieving the above, it is essential to have qualified personnel in all areas incidents, for example users, workers, officials and staff members. There are a variety of specialists in the field of medical applications as, nuclear chemistry, nuclear engineering, radiation protection, medical physics, radiation physics and others. Among the human resource in the country must make up the majority are medical radiologists, highlighting gaps in the number of radiotherapy and nuclear medicine but specially in the medical physics, who is in some way from a special viewpoint of the formal school, new to the country. This is true for the number of facilities which are in the country. The radiation protection responsibilities in medical applications focus primarily on two figures: the radiology safety manager, who is primarily dedicated to the protection of occupationally exposed personnel and the public, and the medical physicist whose functions are geared towards the radiological protection of the patient. The principal legislation in the medical applications area has been enacted and is monitored by the Health Secretary and National Commission on Nuclear Safety and Safeguards, entities that have reached agreements to avoid overlap and over-regulation.

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

    Ethics is a branch of philosophy. Its object is the study of both moral and immoral behaviour in order to make well founded judgements and to arrive at adequate recommendations. The Collins English Dictionary provides the following definitions of the word ethic: Ethic: a moral principle or set of moral values held by an individual or group; Ethics(singular): the philosophical study of the moral value of human conduct and of the rules and principles that ought to govern it; Ethics(pleural): a social, religious or civil code of behaviour considered correct, especially that of a particular group, profession or individual; Ethics(pleural): the moral fitness of a decision, course of action, etc. Ethics has a two-fold objective: Firstly it evaluates human practices by calling upon moral standards; it may give prescriptive advice on how to act morally in a specific kind of situation. This implies analysis and evaluation. Sometimes this is known as Normative ethics. The second is to provide therapeutic advice, suggesting solutions and policies. It must be based on well-informed opinions and requires a clear understanding of the vital issues. In the medical world, we are governed by the Hippocratic Oath. Essentially this requires medical practitioners (doctors) to do good, not harm. There is great interest and even furore regarding ethics in radiation protection

    An external clothing as a main portion of the radiation protective clothing of the present invention is adapted to cover substantially the entire body of a wearer, comprises a moisture permeable material partially or entirely, and has an air supply device equipped with a filter for feeding air to a head portion of the wearer in the external clothing. Cleaned air filtered by the filter is supplied to the head portion of a wearer in the external clothing. The air passes through remarkably perspiratory head, face, shoulder, chest and back portions to remove heat and sweat at sensitively important upper portions of a body, so that humidity is released to remove fatigues and improve workability. In addition, since some extent of internal pressure is exerted to the inside of the external clothing by the air supply, contaminated air does not intrude from the outside to the external clothing. Since the air supply device is attached and carried to the external clothing, there is no air line hose which disturbs operation. (I.S.)

    Since February 2008, participation in the radiation protection course has been a prerequisite for obtaining a CERN personal dosimeter for all Staff Members and Users. All Staff and Users holding a personal dosimeter were informed by the Bulletin and by a personal e-mail sent in February 2008 that they were required to participate in the course before the annual exchange of their dosimeter. Many people had not done so by that time and the Dosimetry Service exceptionally classified them for 2 months as short-term visitors (VCT), a category of monitored personnel to whom the training requirement does not presently apply. As all personnel concerned have since had time to participate in an RP course, this "grace period" will no longer be granted as of 1 October 2008 and the RP course must be completed before the personal dosimeter is exchanged. For newcomers to CERN, and for those returning to CERN after an absence of more than 1 year, one registration as a VCT for two months ...

    The cooperation circle ''Synergies in operational Security'' is a joint working group of the Association of German Safety Engineers (VDSI) and the German-Swiss Professional Association for Radiation Protection (FS). The tasks of the KKSyS are arising from the written agreement of the two associations. This includes work on technical issues. In this regard, the KKSyS currently is dealing with the description of the interface Occupational Safety / Radiation Protection. ''Ignorance is no defense'' - the KKSyS creates a brochure with the working title ''Occupational Safety meets radiation protection - practical guides for assessing the hazards of ionizing radiation.'' The target groups are entrepreneurs and by them instructed persons to carry out the hazard assessment. Our aim is to create practical guides, simple to understand. The practical guides should assist those, who have to decide, whether an existing hazard potential through ionizing radiation requires special radiation protection measures or whether the usual measures of occupational safety are sufficient.

    Depending on the facility, a radiation protective apron (protector) is used to protect the gonad from radiation exposure in chest radiography. To determine the necessity of using a protector during chest radiography, we measured the effect of the protector on the gonad in this study. First, using a human body phantom, we measured the absorbed dose of the female gonad with and without the protector, using a thermoluminescence dosimeter (TLD), and confirmed its protective effect. Using the protector, the absorbed dose was reduced to 28±2% and 39±4% for field sizes of 14 x 17 inch and 14 x 14 inch, respectively. Next, we used Monte Carlo simulation and confirmed, not only the validity of the actual measurement values, but also the fact that the influence of radiation on the absorbed dose of the gonad was mostly from scattered radiation from inside the body for the 14 x 17 inch field size, and also from the X-ray tube for the 14 x 14 inch field size. Although a certain protective effect is achieved by using the protector, the radiation dose to the gonad is only a few μGy even without a protector. Thus, the risk of a genetic effect would be as small as 10 -8 . Given that acceptable risk is below 10 -6 , we conclude the use of a radiation protective apron is not necessary for diagnostic chest radiography. (author)

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

  7. Greetings from Austrian Radiation Protection Association

    2015-01-01

    Austrian Radiation Protection Association (OVS) share with others a long-standing tradition of common endeavours and close collaboration. We have been and are able to influence the European radiation protection environment and IRPA initiatives and policies. We are intrigued by the breadth and comprehensive nature of the symposium programme, covering the most important sub-fields in our profession, and spanning topics from radiation dosimetry to radiobiology, from instrumentation and measurement to radioecology, and from radiation protection for workers and in medicine to our professional responsibilities towards the general public. These topics are timeless and current, providing testimony to the fact that the science of radiation protection is not exhausted. Novel applications of ionizing and non-ionizing radiation, including new modalities in the fields of medical therapy and diagnosis, a resurgence of nuclear energy generation in some parts of the globe, combined with increased efforts for decontamination and decommissioning of existing sites and facilities, they are all attest to the continued need for further research and our professional input and discussion. The national radiation protection associations will have a role to play in both, the advocacy of increased efforts to educate and train our future professionals and the retention of those professionals in our field.

    Radiation protection is a major challenge in the industrial applications of ionising radiation, both nuclear and non-nuclear, as well as in other areas such as the medical and research domains. The overall objective of this textbook is to participate to the development of European high-quality scheme and good practices for education and training in radiation protection (RP), coming from the new Council Directive 2013/59/Euratom laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation. These ERPTS (European Radiation Protection Training Scheme) reflects the needs of the Radiation Protection Expert (RPE) and the Radiation Protection Officer (RPO), specifically with respect to the Directive 2013/59/Euratom in all sectors where ionising radiation are applied. To reflect the RPE training scheme, six chapters have been developed in this textbook: Radioactivity and nuclear physics; Interaction of ionising radiation with matter; Dosimetry; Biological effects of ionising radiation; Detection and measurement of ionising radiation; Uses of sources of ionising radiation. The result is a homogeneous textbook, dealing with the ERPTS learning outcomes suggested by ENETRAPII project (European Network on Education and Training in Radiological Protection II) from the 7. Framework Programme. A cyber-book is also part of the whole training material to develop the concept of 'learning more' (http://www.rpe-training.eu). The production of this first module 'basics' training material, in the combined form of a textbook plus a cyber-book as learning tools, will contribute to facilitate mutual recognition and enhanced mobility of these professionals across the European Union.

  9. Safety Culture on radiation protection

    International Nuclear Information System (INIS)

    Sollet, E.

    1996-01-01

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

  10. External dosimetry - Applications to radiation protection

    International Nuclear Information System (INIS)

    Faussot, Alain

    2011-01-01

    Dosimetry is the essential component of radiation protection. It allows to determine by calculation and measurement the absorbed dose value, i.e. the energy amounts deposited in matter by ionizing radiations. It deals also with the irradiation effects on living organisms and with their biological consequences. This reference book gathers all the necessary information to understand and master the external dosimetry and the metrology of ionizing radiations, from the effects of radiations to the calibration of radiation protection devices. The first part is devoted to physical dosimetry and allows to obtain in a rigorous manner the mathematical formalisms leading to the absorbed dose for different ionizing radiation fields. The second part presents the biological effects of ionizing radiations on living matter and the determination of a set of specific radiation protection concepts and data to express the 'risk' to develop a radio-induced cancer. The third part deals with the metrology of ionizing radiations through the standardized study of the methods used for the calibration of radiation protection equipments. Some practical exercises with their corrections are proposed at the end of each chapter

After outlining previous work on the ethics of radiation protection and risk assessment/management, the authors review ethical thinking on five key issues related to radiation protection and ethics. They formulate each of these five issues in terms of alternative ethical stances: (1) Equity vs. Efficiency, (2) Health vs. Economics, (3) Individual Rights vs. Societal Benefits, (4) Due Process vs. Necessary Sacrifice, and (5) Stakeholder Consent vs. Management Decisions (authors)

  12. The development of radiation protection

    International Nuclear Information System (INIS)

    Pochin, E.E.

    1981-01-01

    The harm that might be caused by radiation exposure was recognised within months of Rontgen's discovery of X-rays, and recommendations for protection of patients and workers with radiation were formulated first in 1928. In the light of increasing radiobiological, genetic and human epidemiological evidence, it became clear that there might be no threshold, below which harmful effects did not occur. Recommendation and practice in radiation protection reflected this opinion from the early 1950's, and emphasised the consequent need for minimising exposures, quantifying risks and revising the dose limits appropriate for internal radiation of body organs.

  13. European Legalisation on Protection Against Cosmic Radiation

    International Nuclear Information System (INIS)

    Courades, M.

    1999-01-01

    Specific provisions on protection of aircrew against cosmic radiation have been laid down for the first time at EU level as part of the Basic Safety Standards for the Health Protection of the General Public and Workers against the Dangers of Ionizing Radiation (Council Directive 96/29/Euratom of 13 May 1996). These provisions, focusing mainly on health and radiological surveillance, are minimal requirements; therefore the Directive leaves significant discretion to the Member States as regards actions to be taken; Member States have to transpose these provisions into national law before 13 May 2000. Further harmonisation of Community regulations on civil aviation safety will be needed in the field of protection against cosmic radiation. This is to obtain a high level of radiation protection for the aircrew and to maintain fair competition under the common transport policy. Additionally, particular requirement are foreseen for detection and monitoring devices as well as for working instructions (Operations Manual). (author)

    Vietnam was one of the earliest countries, who applied ionizing radiation in medicine, since 1923, Dr. Marie Curie had supplied radium sources to Hanoi cancer hospital for radiotherapy. However, we did not give sufficient attention to radiation protection involving, e.g. technology, legislation, until 1980s. Recently with the strong support from International Atomic Energy Agency (IAEA) and Vietnam government nuclear technology has been strongly and widely developed in different branches and radiation protection situation in Vietnam has been improved step by step. Strategy for Peaceful Utilization of Atomic Energy up to 2020 approved by the prime minister on January 3th, 2006 confirms that nuclear power plant will be put in operation by 2020. To ensure the implementation of the strategy, the first priority should be given to radiation protection and nuclear safety. This paper presents shortly some activities of radiation safety in Vietnam. The requirements for developing this field in Vietnam are also discussed. (author)

    1995-01-01

    Computer applications in general and diagnostic radiology in particular are becoming more widespread. Their application to the field of radiation protection in medical imaging, including quality control initiatives, is similarly becoming more widespread. Advances in computer technology have enabled departments of diagnostic radiology to have access to powerful yet affordable personal computers. The application of databases, expert systems and computer-based learning is under way. The executive information systems for the management of dose and QA data that are under way at IRS are discussed. An important consideration in developing these pragmatic software tools has been the range of computer literacy within the end user group. Using interfaces have been specifically designed to reflect the requirements of many end users who will have little or no computer knowledge. (Author)

    2013-04-01

    Radiation protection in nuclear medicine in this project is concerned with the reduction of doses to workers, patients and members of the public. Protection of workers is achieved by adopting good personal habits, good housekeeping, proper use of personal protective devices and equipment, attend training and have continuous education. Exposure to radiation of workers and the members of the public are minimised by proper management of radioactive waste and safe transport of radioactive material. The design and shielding of a nuclear medicine department shall further provide for the protection of the worker, the patient and the general public. Protection of patient is achieved by justifying the procedure, delivering the minimum radiation dose possible to the patient while obtaining the best image quality and applying guidance levels. Special considerations shall be given to pregnant and breast-feeding patients. Quality assurance programme through image quality, radiopharmaceutical quality and patient records on nuclear medicine procedures shall provide assurance to the patient. (au)

  6. Radiation protection information

    International Nuclear Information System (INIS)

    From the measurements and discussion presented in this report, the following conclusions may be drawn: The population doses from naturally occuring radiation is on average lower in Denmark and much lower in Iceland than in the other Nordic countries. In Sweden, Finland and Norway the largest contributors to the population doses from naturally occuring radiation are radon daughters in indoor air. For Denmark and Iceland, radon daughters contribute about the same to the total effective dose equivalent as the external gamma radiation. Some groups of people in the Nordic countries are highly exposed to radon daughters. In some cases, the received doses are very high (higher than the dose limit for radiation workers). From the conclusions above, the radon daughter problem should be given priority, at least in Sweden, Finland and Norway, especially regarding the search for population groups receiving the highest doses

    The basis of EU radiation protection legislation is the EURATOM Trealy. It is discussed whether the Treaty offers a legal basis for the protection of the natural environment. The incorporation of provisions pertaining to the nuclear fuel cycle or to radioactive substances in general environmental legislation is explained, as well as the possible implications of international conventions subscribed by the European Union. The European Commission is in the process of developing an overall approach to risk analysis for the protection of health, consumer interests, and the environment. It is examined to what extent the consideration of the impact of radiation on the natural environment fits in the overall framework and whether the principles underlying classical radiation protection are applicable to biota. Specific attention is given to situations where high levels of environmental radioactivity would require intervention. (Author)

    1976-06-01

    The EPA, under its Federal Guidance authorities, is responsible for advising the President on all matters pertaining to radiation and, through this mechanism, to provide guidance to other Federal agencies on radiation protection matters. Highlights are presented of significant radiation protection activities of all Federal agencies which were completed in 1975, or in which noteworthy progress was made during that period, and those events affecting members of the public. State or local activities are also presented where the effects of those events may be more far-reaching. At the Federal level significant strides have been made in reducing unnecessary radiation exposure through the efforts of the responsible agencies. These efforts have resulted in the promulgation of certain standards, criteria and guides. Improved control technologies in many areas make it feasible to reduce emissions at a reasonable cost to levels below current standards and guides. This report provides information on the significant activities leading to the establishment of the necessary controls for protection of public health and the environment. Radiation protection activities have been undertaken in other areas such as medical, occupational and consumer product radiation. In the context of radiation protection, ancillary activities are included in this report in order to present a comprehensive overview of the events that took place in 1975 that could have an effect on public health, either directly or indirectly. Reports of routine or continuing radiation protection operations may be found in publications of the sponsoring Federal agencies, as can more detailed information about activities reported in this document.

    Reference X-, gamma, beta and neutron radiation fields complying with the ISO and ANSI standards have been established and evaluated to provide a basic technical support in national radiation protection dosimetry program and to provide calibration measurement devices. Personal dose evaluation algorithm has been developed with these reference radiation fields, which comply well with both domestic and the new ANSI N13.11, to evaluate accurate personal dose equivalents. A personal internal dosimetry algorithm which can estimate the intakes of radionuclides from the results of in vivo bioassay and the resulting internal doses has been developed and verified its performance. It was also evaluated to be equality excellent compared with those being used in foreign countries and used to make a computer code for internal dose evaluation which can be run with PC under the Windows environment. A BOMAB phantom for precise calibration of in vivo system has been also designed, fabricated and test-evaluated. Based on the ALARA concept of the optimization principle of radiation protection, a method for estimating the cost for radiation protection has been studied and an objective monetary cost of detriment due to radiation exposure, called {alpha} value ($/man-Sv) has been derived and proposed based on the Korean socio-economic situation and human risk factors to provide basic data for the radiation protection optimization study in Korea.

    Medical exposure is the largest human-made source of radiation exposure, accounting for more than 95% of radiation exposure. Furthermore, the use of radiation in medicine continues to increase worldwide — more machines are accessible to more people, the continual development of new technologies and new techniques adds to the range of procedures available in the practice of medicine, and the role of imaging is becoming increasingly important in day to day clinical practice. The introduction of hybrid imaging technologies, such as positron emission tomography/computed tomography (PET/CT) and single photon emission computed tomography (SPECT)/CT, means that the boundaries between traditional nuclear medicine procedures and X ray technologies are becoming blurred. Worldwide, the total number of nuclear medicine examinations is estimated to be about 35 million per year.

    This paper examines trends in occupational and public health standard setting including those which apply to radiation protection practices. It is the authors' contention that while regulators, unions and employees demand higher standards of radiation protection and industry attempts to comply with tight controls of radiation exposure in the workplace, these standards are out of step with standards applied to health away from the workplace, recreational activity and other areas of industrial hygiene. The ultimate goal of an improvement in the health of the nation's workforce may no longer be visible because it has been submerged beneath the predominating concern for one aspect of health in the workplace. 35 refs., 5 tabs

    1977-10-01

    The introduction of new concepts such as the effective dose equivalent, the collective dose and the dose commitment, and the application of the basic principles of justification, optimization and individual dose limitation has had a major impact on the planning and implementation of radiation protection during the last few years. The basic principles are summarized in ICRP Publication 26. It is a chalenge to research in radiobiology, genetics and health physics to explore the scientific foundation of the current principles of radiation protection. The most interesting trend to-day, however, is the observation that the principles applied in radiation protection have now been generally recognized and accepted to the extent that they become utilized in the protection of man against non-radioactive carcinogenic substances and environmental pollutants.

    The European Commission has funded within its 6th Framework Programme a three-year project (2005-2007) called CONRAD, COordinated Network for RAdiation Dosimetry. A major task of the CONRAD Work Package 'complex mixed radiation fields at workplaces' was to organise a benchmark exercise in a workplace field at a high-energy particle accelerator where neutrons are the dominant radiation component. The CONRAD benchmark exercise took place at the Gesellschaft fuer Schwerionenforschung mbH (GSI) in Darmstadt, Germany in July 2006. In this paper, the results of the spectrometry using four extended -range Bonner sphere spectrometers of four different institutes are reported. Outside Cave A the neutron spectra were measured with three spectrometers at six selected positions and ambient dose equivalent values were derived for use in the intercomparison with other area monitors and dosemeters. At a common position all three spectrometers were used to allow a direct comparison of their results which acts as an internal quality assurance. The comparison of the neutron spectra measured by the different groups shows very good agreement. A detailed analysis presents some differences between the shapes of the spectra and possible sources of these differences are discussed. However, the ability of Bonner sphere spectrometers to provide reliable integral quantities like fluence and ambient dose equivalent is well demonstrated in this exercise. The fluence and dose results derived by the three groups agree very well within the given uncertainties, not only with respect to the total energy region present in this environment but also for selected energy regions which contribute in certain strength to the total values. In addition to the positions outside Cave A one spectrometer was used to measure the neutron spectrum at one position in the entry maze of Cave A. In this case a comparison was possible to earlier measurements.

    The work scope of 'Biological Research for the Radiation Protection' had contained the research about ornithine decarboxylase and its controlling proteins, thioredoxin, peroxiredoxin, S-adenosymethionine decarboxylase, and glutamate decarboxylase 67KD effect on the cell death triggered ionizing radiation and H 2 O 2 (toxic agents). In this study, to elucidate the role of these proteins in the ionizing radiation (or H 2 O 2 )-induced apoptotic cell death, we utilized sensesed (or antisensed) cells, which overexpress (or down-regulate) RNAs associated with these proteins biosynthesis, and investigated the effects of these genes on the cytotoxicity caused by ionizing radiation and H 2 O 2 (or paraquat). We also investigated whether genisteine(or thiamine) may enhance the cytotoxic efficacy of tumor cells caused by ionizing radiation (may enhance the preventing effect radiation or paraquat-induced damage) because such compounds are able to potentiate the cell-killing or cell protecting effects. Based on the above result, we suggest that the express regulation of theses genes have potentially importance for sensitizing the efficiency of radiation therapy of cancer or for protecting the radiation-induced damage of normal cells

    According to European law, the Basic Safety Standards (BSS) published by the European Council in 1996 and the Council Directive on health protection of individuals against dangers of ionising radiation in relation to medical exposure had to be transferred into national law within due time. In 2001 the new Ordinance for the Implementation of the Euratom Guidelines on Radiation Protection] was published, which replaces the old Radiation Protection Ordinance. The new German Ordinance adapts the European Directive to German law, covering the general principles but even giving more details in many fields of radiation protection. The BSS scope certainly is much broader than the prescriptions important for the field of radiation protection in nuclear power plants. According to the scope of this workshop on occupational exposure in nuclear power plants - and as the BSS most probably will be quite familiar to all of you - after a short general overview on relevant contents of the German Ordinance, this presentation will focus on the main issues important in the operation of NPP and especially on some areas which may give rise to necessary changes caused by the new Ordinance.

    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 radiological protection of workers occupationally exposed to ionizing radiation (X-ray diagnoses, Nuclear Medicine, Radiotherapy and Dental) is essential to minimize the appearance of radiation effects. The ways to reduce the potential for exposure of workers are: Time, Distance , and Shielding. The most important purpose of radiation protection is to provide safe conditions for activities involving ionizing radiation, basic safety conditions that must be observed in professional practice. The professional must have full knowledge of the subject and deepen in the revision of norms and guidelines related to radiation protection establish by the Vigilancia Sanitaria - ANVISA, and Comissao Nacional de Energia Nuclear - CNEN, Brazil. The study was conducted in a technical school for the Technical Training Course in Radiology, where the students are invited to think deeply about the radiation protection of themselves, the patients and the environment. Developed since July 2012, with the participation of 30 students, with a leading class -three teachers assisting in the development of the project . With this project there was an awareness of both students, as instructors stage accompanying the daily lives of students and their own colleagues. Following the same objective in 2013 the project continues with more adept at radioprotection

    The radiopharmaceutucal 111 In-oxine is used in labelling of different blood cells and proteins. Due to its liquid state, there is always a risk for contamination during handling procedures. The aim of the project was to evaluate the contamination risks, when using this radiopharmaceutical. The investigation includes calculations of the absorved dose to the skin after a contamination of 111 In-oxine, including the radionuclide impurity 114 In m / 114 In. Investigations of 288 protection gloves shows that there is always a risk for contamination, when working with 111 In-oxine. On the protection gloves, we found activities normally ranging from a 100 Bq up to a few kBq. Noticeable is the contamination on the vials, already before their use. Besides 111 In we found most of the radionuclides used in nuclear medicine, with activities up to tens of kBq. The radionuclide impurity was cleary detectable but below the recommended value. The penetration of 111 In-oxine protection gloves of latex was negligible. Measurements of penetration in skin was evaluated with two independent methods; in vivo using a surface barrier detector, and by autoradiography. The measured penetration was less than a few micrometers. Calculation from the experimental contamination values show that the absorbed dose to the basal cell layer could be in order of several Gy.

    1983-01-01

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

    Entry into hazardous areas without the proper protective equipment is extremely dangerous and must be prevented whenever possible. Current postings of radiological hazards at the Rocky Flats Environmental Technology Site (RFETS) do not incorporate recent findings concerning effective warning presentation. Warning information should be highly visible, quickly, and easily understood. While continuing to comply with industry standards (e.g., Department of Energy (DOE) guidelines), these findings can be incorporated into existing radiological sign design, making them more effective in terms of usability and compliance. Suggestions are provided for designing more effective postings within stated guidelines

    Almost all radiation protection standards, manuals and textbooks have been written in and for industrialized countries in temperate climates, and most research effort and instrument manufacturers are also located there. There has been relatively little interest in the completely different socio-economic and climatic conditions in many developing countries. Some of the important differences in conditions, such as high temperatures and relative humidities, electric-power failures and voltage fluctuations, shortage of trained manpower, etc., are discussed, and suggestions are made how to minimize their impacts. Other important matters that are considered are recruitment and training, optimized organizational structures, and the proper choice of research topics in the radiation protection field. (author)

    2017-01-01

    The WARP report issued by the NCRP study committee estimates that in ten years there will be a human capital crisis across the radiation safety community. The ability to respond to this shortage will be amplified by the fact that many radiation protection (health physics) academic programs will find it difficult to justify their continued existence since they are low volume programs, both in terms of enrollment and research funding, compared to the research funding return and visibility of more highly subscribed and highly funded academic disciplines. In addition, across the national laboratory complex, radiation protection research groups have been disbanded or dramatically reduced in size. The loss of both of these national resources is being accelerated by low and uncertain government funding priorities. The most effective solution to this problem would be to form a consortium that would bring together the radiation protection research, academic and training communities. The goal of such a consortium would be to engage in research, education and training of the next generation of radiation protection professionals. Furthermore the consortium could bring together the strengths of different universities, national laboratory programs and other entities in a strategic manner to accomplish a multifaceted research, educational and training agenda. This vision would forge a working and funded relationship between major research universities, national labs, four-year degree institutes, technical colleges and other partners.

    2001-01-01

    Monitoring of environmental radioactivity as well as complex investigations for precautionary radiation protection are carried out in Hamburg by two radiation monitoring labs. The spectrum of their tasks is specified by the media to be investigated. The tasks are originating from the Federal Precautionary Radiation Protection Act and from local needs. Mostly since a lot of years all interesting materials are analysed for their radioactivity content, as a safe and precautionary radiation protection demands. Until today samples show the influence of global nuclear weapon fallout of the period until 1964. Partly they show the radioactivity of Caesium originating from the Chernobyl accident. Since ten years the radioactivity contents in the material investigated are decreasing. Mostly the activity reached levels as at the end of 1985. The basic food stuff investigated in Hamburg can be considered as to be uncontaminated by radioactivity. With the introduction of the Federal Precautionary Radiation Protection Act, a series of new investigation programs and investigation methods were developed. This allows a better preparedness for extraordinary situations of increased radioactivity in the environment as 12 years ago. Thus a precise assessment of situations of increased radioactivity levels can be given together with coordinated and solid information to the public concerning provisions and actions. (orig.) [de

    1978-01-01

    The requirement to keep radiation exposure as low as reasonably achievable, linked with the growing number of workers whose exposure to radiation must be strictly controlled, requires intensified efforts directed towards the provision of adequate radiation monitoring programmes. This symposium was intended to review the advances that have been made in methods, techniques and instrumentation for radiation protection monitoring. Thus the symposium complemented the detailed consideration that had already been given to two closely related topics, that of environmental monitoring and of monitoring radioactive airborne and liquid discharges from nuclear facilities. The first topic had been dealt with in detail in an Agency symposium held in November 1973 in Warsaw and the second was treated in an Agency symposium held in September 1977 in Portoroz. The present symposium covered a broad range of topics under the following main headings: Monitoring of external exposure (three sessions),Contamination monitoring (three sessions), Radiation monitoring programmes (one session), Calibration, and use of computers (two sessions). An introductory paper described the purpose of radiation protection monitoring and its historical development. It drew attention to the gradual change from the threshold dose hypothesis to the hypothesis of direct proportionality between dose and effect and discussed practical implications of the recommendations recently issued by the International Commission on Radiological Protection (ICRP). It became apparent that guidance on the application of these recommendations is urgently needed. This guidance is presently being prepared by ICRP

    As protection sheets used in radioactivity administration areas, a thermoplastic polyurethane composition sheet with a thickness of less 0.5 mm, solid content (ash) of less than 5% and a shore D hardness of less than 60 is used. A composite sheet with thickness of less than 0.5 mm laminated or coated with such a thermoplastic polyurethane composition as a surface layer and the thermoplastic polyurethane composition sheet applied with secondary fabrication are used. This can satisfy all of the required properties, such as draping property, abrasion resistance, high breaking strength, necking resistance, endurance strength, as well as chemical resistance and easy burnability in burning furnace. Further, by forming uneveness on the surface by means of embossing, etc. safety problems such as slippage during operation and walking can be overcome. (T.M.)

    Sunami, Yoshio; Mitsumori, Kojiro

    1980-01-01

    Purpose: To prevent radioactivity from leaking outside of a reactor container by way of pipeways passing therethrough, by supplying pressurized fluid between each of a plurality of valves for separating the pipeways. Constitution: Pressurized fluid is supplied between each of a plurality of valves for separating pipeways. For instance, water in a purified water tank is pressurized by a pressure pump and the pressure of the pressurized water is controlled by a differential pressure detector, a pressure controller and a pressure control valve. In the case if a main steam pipe is ruptured outside of the reactor container or to be repaired, the separation valves are wholly closed and then the pressurizing device is actuated to supply pressurized water containing no radioactivity from the purified water tank to the position between the valves. The pressure in the pressurized water is controlled such that it is always higher by a predetermined level than the pressure in the reactor. This prevents the radioacitivity in the reactor core from leaking outside of the container passing through the valves, whereby radiation exposure in the working can be reduced and the circumferential contamination upon accident of pipeway rupture can be decreased.

    2016-04-14

    Radiation protection calibration facilities are essential to ensure the correct operation of radiation protection instrumentation. Calibrations are performed in specific radiation fields according to the type of instrument to be calibrated: neutrons, photons, X-rays, beta and alpha particles. Some of the instruments are also tested in mixed radiation fields as often encountered close to high-energy particle accelerators. Moreover, calibration facilities are of great importance to evaluate the performance of prototype detectors; testing and measuring the response of a prototype detector to well-known and -characterized radiation fields contributes to improving and optimizing its design and capabilities. The CERN Radiation Protection group is in charge of performing the regular calibrations of all CERN radiation protection devices; these include operational and passive dosimeters, neutron and photon survey-meters, and fixed radiation detectors to monitor the ambient dose equivalent, H*(10), inside CERN accelerators and at the CERN borders. A new state-of-the-art radiation protection calibration facility was designed, constructed and commissioned following the related ISO recommendations to replace the previous ageing (more than 30 years old) laboratory. In fact, the new laboratory aims also at the official accreditation according to the ISO standards in order to be able to release certified calibrations. Four radiation fields are provided: neutrons, photons and beta sources and an X-ray generator. Its construction did not only involve a pure civil engineering work; many radiation protection studies were performed to provide a facility that could answer the CERN calibration needs and fulfill all related safety requirements. Monte Carlo simulations have been confirmed to be a valuable tool for the optimization of the building design, the radiation protection aspects, e.g. shielding, and, as consequence, the overall cost.

    Over 40 years have passed since the research of the Manhattan Project suggested the possibility of chemical protection against ionizing radiation. During that time, much has been learned about the nature of radiation-induced injury and the factors governing the expression of that injury. Thousands of compounds have been tested for radioprotective efficacy, and numerous theories have been proposed to account for these actions. The literature on chemical radioprotection is large. In this article, the authors consider several of the mechanisms by which chemicals may protect against radiation injury. They have chosen to accent this view of radioprotector research as opposed to that research geared toward developing specific molecules as protective agents because they feel that such an approach is more beneficial in stimulating research of general applicability. This paper describes the matrix of biological factors upon which an exogenous radioprotector is superimposed, and examines evidence for and against various mechanisms by which these agents may protect biological systems against ionizing radiation. It concludes with a brief outlook for research in chemical radioprotection

    The purpose of researches is development of methods and means of reduction of radiation risk caused by the Chernobyl accident consequences by means of decrease of both individual and collective dozes by realization of special protective measures. The reconstruction of average collective accumulated irradiation dozes of the inhabitants of the contaminated populated localities of Belarus is carried out; the forecast of development of radiation induced oncologic diseases is given. The laws of formation of annual irradiation dozes are investigated; the prevailing role of internal irradiation dozes in formation of total dose loadings is detected. On this basis a number of practical projects directed on creation of effective land tenure and decrease of radioactive contamination of agricultural production, as well as decontamination technologies and radioactive waste management are executed. Are given the results of researches carried out in Belarus in 1997 on the following directions: dose monitoring of the population, estimation and forecast of both collective irradiation dozes and risks of radiation induced diseases; development and optimization of a complex of measures for effective land use and decrease of radioactive contamination of agricultural production in order to reduce irradiation dozes of the population; development of complex technologies and means of decontamination, treatment and burial of radioactive wastes; development and ground of the measures for increase of radiation protection of the population of Belarus during of the reducing period after the Chernobyl accident; development of complex system of an estimation and decision-making on problems of radiation protection of the population living on contaminated territories

    Close ties exist between nuclear safety and radiation protection. Nuclear safety is made up of all the arrangements taken to prevent accidents occurring in nuclear facilities, these accidents would certainly involved a radiological aspect. Radiation protection is made up of all the arrangements taken to evaluate and reduce the impact of radiation on workers or population in normal situations or in case of accident. In the fifties the management of radiological hazards was based on the quest for minimal or even zero risk. This formulation could lead to call some activities in question whereas the benefits for the whole society were evident. Now a new attitude more aware of the real risks and of no wasting resources prevails. This attitude is based on the ALARA principle whose purpose is to maintain the exposure to radiation as low as reasonably achievable taking into account social and economic concerns. This document regroups articles illustrating different aspects of the radiation protection in nuclear facilities such as a research center, a waste vitrification workshop and a nuclear power plant. The surveillance of radiological impacts of nuclear sites on environment is examined, a point is made about the pending epidemiologic studies concerning La Hague complex. (A.C.)

  3. Radiation protection in veterinary medicine

    International Nuclear Information System (INIS)

    1991-01-01

    Diagnostic radiology is an essential part of present-day veterinary practice. The need for radiation protection exists because occupational exposure to ionizing radiation can result in deleterious effects that may manifest themselves not only in exposed individuals but in their descendants as well. These are respectively called somatic and genetic effects. Somatic effects are characterized by observable changes occurring in the body organs of the exposed individual. These changes may appear from within a few hours to many years later, depending on the amount and duration of exposure of the individual. In veterinary medicine, the possibility that anyone may be exposed to enough radiation to create somatic effect is extremely remote. Genetic effects are more a cause for concern at the lower doses used in veterinary radiology. Although the radiation doses may be small and appear to cause no observable damage, the probability of chromosomal damage in the germ cells, with the consequence of mutations, does exist. These mutations may give rise to genetic defects and therefore make these doses significant when applied to a large number of individuals. There are two main aspects of the problem to be considered. First, personnel working with X-ray equipment must be protected from excessive exposure to radiation during their work. Secondly, personnel in the vicinity of veterinary X-ray facilities and the general public require adequate protection

    Aspects of radiation protection in nuclear medicine and the role of the Dutch Society for Nuclear Medicine in these are discussed. With an effective dose-equivalence of averaged 3 mSv per year per nuclear medical examination and about 200.000 examinations per year in the Netherlands, nuclear medicine contributes only to a small degree to the total averaged radiation dose by medical treating. Nevertheless from the beginning, besides to protection of environment and personnel, much attention has been spent by nuclear physicians to dose reduction with patients. Replacing of relatively long living radionuclides like 131 I by short living radionuclides like 99m Tc is an example. In her education and acknowledgement policy the Dutch Society for Nuclear Medicine spends much attention to aspects of radiation reduction. (author). 3 tabs

    Radiation Protection Programmes are being considered the best way to promote safety culture and to spread and propagate European basic safety standards. It is widely accepted that training is an important tool to upgrade competence for radiation exposed workers. The Spanish Radiation Protection Education and Training Programmes provide a solid and integrated educational model, which takes into account the variety of applied fields, the different levels of responsibilities, the technological and methodological advances, as well as the international tendencies. The needs for a specialised training on Radiation Protection (RP) for exposed workers appears into the Spanish regulation in 1964. National initial training programmes are well established since 1972. Individual certifications, based on personal licences are required for exposed workers. The Spanish regulation also includes continuous and on the job RP training. The educational programmes are being continuously updating and improving. CIEMAT plays an important role in RP Spanish training, improving and modifying the previous RP courses and developing new programmes in order to complete the RP training levels. To achieve Radiation Protection objectives, new technological media for educational methods and material are taking into account. Nevertheless, Spanish RP education and training model has to be improved in some aspects. The purpose of this paper is to analyse the situation and the future needs to be considered in order to complete the RP training processes

    Knowledge of the spectrum of energies for beta, gamma, and neutron radiation experienced in the field is crucial to the proper interpretation of personnel dose. Calibration sources and techniques are determined on the basis of their relationship to field exposure. Selected techniques were used to obtain neutron, photon, and beta energy spectra data at several Hanford locations. Four neutron energy spectra and dose measurement methods were used: (1) multisphere spectrometer system; (2) tissue equivalent proportional counter (TEPC); (3) RASCAL (9'' to 3'' sphere ratios); and (4) helium-3 neutron spectrometer. Gamma spectroscopy was done using standard techniques. A specially designed TLD dosimeter was used to obtain beta spectrum measurements. The design and use of each of these instruments is described in the body of this report. Data collected and analyzed for each of the Hanford locations are included

  11. Problems of radiation protection optimization

    International Nuclear Information System (INIS)

    Morkunas, G.

    2003-01-01

    One of the basic principles - optimization of radiation protection - is rather well understood by everybody engaged in protection of humans from ionizing radiation. However, the practical application of this principle is very problematic. This fact can be explained by vagueness of concept of dose constraints, possible legal consequences of any decision based on this principle, traditions of prescriptive system of radiation protection requirements in some countries, insufficiency of qualified expertise. The examples of optimization problems are the different attention given to different kinds of practices, not optimized application of remedial measures, strict requirements for radioactive contamination of imported products, uncertainties in optimization in medical applications of ionizing radiation. Such tools as international co-operation including regional networks of information exchange, training of qualified experts, identification of measurable indicators used for judging about the level of optimization may be the helpful practical means in solving of these problems. It is evident that the principle of optimization can not be replaced by any other alternative despite its complexity. The means for its practical implementation shall be searched for. (author)

    Application of the ionizing radiation in almost all the fields of human activities enlarged the knowledge of their harming influence on the living beings. At the same time there have been many investigations of different chemical means that could successfully be used in protection from radiation. Until today several hundreds of different chemical compounds have been considered to be a potential chemical radioprotector. Analyzing the results of investigating great number of potential radioprotective compounds, it can be said that those containing sulfur provide the most effective protection. That are aminothiols, aminodisulphides, derivatives of thiourea, thiosulphuric and thiophosphate acid, dithiocarbamates, thiazolines, some of biogen amines and their derivates. Among the investigated compounds there is a certain number that, under some circumstances, has shown a protective effect on the experimental animals. In the work comparative investigation of the protective effect of cistaphosa (WR-638) and gamaphosa (WR-2721) have been researched on the big experimental animals, radiated with a high level of X-radiation. Well protective influence of both radioprotectors has been proven but gamafos showed higher efficiency. (author)

    Radiation protection by apoptosis control is the suppression of cell death in highly radiosensitive tissues. This paper describes the outline of radiation-induced apoptosis framework, apoptosis-concerned target molecules possibly related to apoptosis by radiation and their inhibitors. Although there are intrinsic (via mitochondria) and extrinsic (via death receptor) pathways in apoptosis, this review mainly mentions the former which is more important in radiation-induced apoptosis. Those molecules known at present in the apoptosis are caspase, Bcl-2 family and p53. Caspase, a group of cystein proteases, initiates apoptosis but its inhibition is known not always to result in apoptosis suppression, suggesting the existence of caspase-independent pathways. Bcl-2 family involves apoptosis-suppressing (possessing BH domains) and -promoting (lacking BH domains or possessing BH3 domain alone/BH3-only protein) groups. Two p53-transcription-dependent and one -independent pathways in p53-induced apoptosis are known and p53 can be a most possible target molecule since it positions at the start of apoptosis. Authors have found a vanadate inactivates p53. Inhibitors affecting upstream molecules of apoptosis will be the most useful candidate for apoptosis suppression/radiation protection. (S.I.) 106 refs

    Tests type were made (type test) in the following commercial instrumentation commonly used in radiological protection: Geiger-Mueller Counters (FH40 FE), Plastic Scintillators (NE-BP/6/4A), Ionization Chambers (RO-5) and Proportional Counters (HP-100A; gas:P-10). With object of checking the possibility that these they can carry out the new operative unit ICRU, H' (0.07; α). The tests consisted on determining the energy and angular response of the detectors in secondary patron fields of beta radiation, for isotopes of 90 Sr/ 90 Y (1850 MBq and 74 MBq and 147 Pm(518 MBq). The results show the inadequate of these commercial instruments for the realization of the H' operative unit (0.07; α) in beta external fields.

  18. Radiation protection at new reactors

    2000-01-01

    The theoretical knowledge and the feedback of operating experience concerning radiations in reactors is now considerable. It is available to the designer in the form of predictive softwares and data bases. Thus, it is possible to include the radiation protection component throughout all the design process. In France, the existing reactors have not been designed with quantified radiation protection targets, although considerable efforts have been made to reduce sources of radiation illustrated by the decrease of the average dose rates (typically a factor 5 between the first 900 MWe and the last 1300 MWe units). The EDF ALARA PROJECT has demonstrated that good practises, radiation protection awareness, careful work organization had a strong impact on operation and maintenance work volume. A decrease of the average collective dose by a factor 2 has been achieved without noticeable modifications of the units. In the case of new nuclear facilities projects (reactor, intermediate storage facility,...), or special operations (such as steam generator replacement), quantified radiation protection targets are included in terms of collective and average individual doses within the frame of a general optimization scheme. The target values by themselves are less important than the application of an optimization process throughout the design. This is because the optimization process requires to address all the components of the dose, particularly the work volume for operation and maintenance. A careful study of this parameter contributes to the economy of the project (suppression of unecessary tasks, time-saving ergonomy of work sites). This optimization process is currently applied to the design of the EPR. General radiation protection provisions have been addressed during the basic design phase by applying general rules aiming at the reduction of sources and dose rates. The basic design optimization phase has mainly dealt with the possibility to access the containment at full

    Full text: Regarding natural phenomena understood or not, the absolute truth must be somewhere. In fact, there is no evidence that neither nature nor the phenomena that it includes were 'created' to be understood. Except for the fact that Man appeared through the same process, with his curiosity, capacity to perceive and manipulate, his greed for power and fears. In general, the attitude towards questions for which the absolute truth has not been reached varies from ignorance/indifference to the search of knowledge through scientific methodology, and may even be based on beliefs. The fact that the interaction between ionizing radiations and living beings results in biological effect is true. That the biological effect of high doses of radiation, absorbed outside the context of medicine, is hazardous for the irradiated individuals also seems to be true. That any dose is dangerous, or not, is debatable: the available information and knowledge are not consistent enough to end the question; and so, the absolute truth remains hidden. Radiological Protection is founded on the principle that any increase of dose results in an increase in the risk of cancer, and that this risk must be kept as low as possible. It is therefore based on this 'belief' that the international organisms of radiological protection emit recommendations aiming the protection of people and the environment. What is interesting about this question is that because of restrictions imposed by regulating agencies, populations, members of the public and the environment are properly protected against harmful effects of ionizing radiations, which makes the truth no longer interesting. Radiological Protection is a requirement associated to all activities involving nuclear energy. It satisfies several interests and opposes others. The greater the opposed interests and the perception that the absolute truth can represent dialectic advantage to one of the parts, the greater the perception of the importance of its

    Short-lived radiopharmaceuticals, such as 99m Tc labelled compounds, are prepared in the in-house pharmacy of the hospital. In addition, preparation of smaller doses for administration from the bulk material of the finished product received from the manufacturers, also involves considerable work for the radiopharmacist in the hospital. Hence they should be well informed about the radiation hazards and should be aware of the protective measures to be taken while handling radioactive materials for keeping the radiation levels in the laboratory and their personnel doses well within the specified limits. 3 refs., 5 tabs

    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, and this report has been prepared to provide the guidance that may be required in this development. The original version of the report on this subject was published in 1964 as Technical Reports Series No. 31 entitled ''Training in Radiological Protection: Curricula and Programming''. In 1975 a second version was published entitled ''Training in Radiological Protection for Nuclear Programmes'' as Technical Reports Series No. 166. This publication is intended mainly for use by persons who are responsible for organizing training programmes in radiation protection. It also reflects the policy of the Agency to have continuing standardized training in radiation protection. In addition to a small change in the title of the report, some concepts and ideas which are no longer applicable have been omitted and new information included. An important part of this report is the list of courses now offered in many Member States

  2. 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

    2011-01-01

    International standards for radiation protection are issued by many bodies. These bodies differ to a large extent in their organisation, in the way the members are designated and in the way the international standards are authorised by the issuing body. Large differences also exist in the relevance of the international standards. One extreme is that the international standards are mandatory in the sense that no conflicting national standard may exist, the other extreme is that national and international standards conflict and there is no need to resolve that conflict. Between these extremes there are some standards or documents of relevance, which are not binding by any formal law or contract but are de facto binding due to the scientific reputation of the issuing body. This paper gives, for radiation protection, an overview of the main standards issuing bodies, the international standards or documents of relevance issued by them and the relevance of these documents.

    The nuclear generation program at Ontario Hydro was initiated in the early 1960s. Over the last two decades the program has expanded to a planned capacity of ∼ 14,000 MW(electric) by 1992. Each of the nuclear stations consists of four identical reactor units and they range in size from 520 to 880 MW(electric). The overall objectives of Ontario Hydro's radiation protection program are stated as follows: (1) to prevent detrimental nonstochastic health effects to employees and the public; (2) to limit detrimental stochastic health effects occurring in employees or the public to levels as low as reasonably achievable (ALARA), social and economic factors being taken into account; and (3) to provide a level of health and safety that is as good as, or better than, comparable safe industries. Although many elements of the radiation protection program are similar to those adopted by other electrical utilities around the world, there are some unique features that have played an important part in the improvements achieved. These include: management commitment, design responsibility, radiation protection training, operations control, and work planning. The issues that need to be addressed in striving for overall excellence in radiological safety over the next decade are summarized

    Already the 24 th annual international conference 'Days of Protection from Radiation' was taking place in Jan Sverma Hotel in Demaenova dolina on 26-29 November 2001. More than 180 participants from the Slovak Republic and the Czech Republic participated in the meetings of experts on protection from radiation. Representative of IAEA Division for Protection from Radiation and the representatives of several European companies securing the project, advisory and supplier's activities in dosimetry of ionising radiation also participated in the conference. The participants discussed in 7 expert panels the issue of protection from radiation in the legislative field, in the nuclear facilities operation and in medicine. The expert part of the other panels concerned the issues of ionising radiation impact on the environment and working environment, natural radio-nuclides, including radon and biologic impacts of radiation. One separate panel was dedicated to device techniques and methods of dosimetry of ionising radiation. More than 45 expert lectures and more than 40 poster presentations were presented at the conference during 3 days. The exhibition and presentation of measuring technique products and devices and of materials used in the area of radiation protection and nuclear medicine was prepared during the course of the conference. Participation in the conference showed that a great interest in problems of protection from radiation persists. This was proved by rich lecturing activity and wide discussions on the floor and during the poster presentations. Participants were satisfied since the organisers of the event prepared a worthy event with the rich expert themes at a good organisational and social level in a beautiful environment of Low Tatras

    2012-01-01

    Radiation protection instrumentation plays very important role in radiation protection and surveillance programme. Radiation detector, which appears at the frontal end of the instrument, is an essential component of these instruments. The instrumental requirement of protection level radiation monitoring is different from conventional radiation measuring instruments. Present paper discusses the new type of nuclear radiation detectors, new protection level instruments and associated electronic modules for various applications. Occupational exposure to ionizing radiation can occur in a range of industries, such as nuclear power plants; mining and milling; medical institutions; educational and research establishments; and nuclear fuel cycle facilities. Adequate radiation protection to workers is essential for the safe and acceptable use of radioactive materials for different applications. The radiation exposures to the individual radiation workers and records of their cumulative radiation doses need to be routinely monitored and recorded

  14. Evolution of Radiation Protection System in Kenya

    International Nuclear Information System (INIS)

    Maina, J. A. W.

    2004-01-01

    Promulgation of radiation protection legislation in Kenya dates back to 1982, was revised in 1985 and became operational in 1986. This law, the Radiation Protection Act, establishes the Radiation Protection Board as the National Regulatory Authority, with an executive Inspectorate headed by the Secretary to the Board. Subsidiary legislation on radiological practices and standards were subsequently published. The Inspectorate carries out the National programme for notification, authorization, inspection and enforcement. Nuclear applications for peaceful purposes in Kenya are on the increase in all major fields of socio-economic development. Provision of regulatory services, guidance and enforcement procedures, has had a net growth over the last fifteen years. However, staff retention has been declining over the years in a market where job opportunities, with relatively high incentives, are high either inside or outside the country. Human and equipment resource development has therefore not kept pace and this has hampered effective and efficient provision of services. The poor status of the economy has had its impact on delivery of quality, effective and efficient radiation protection services. Provision of radiation services and acquisition of radiation detection and measurement equipment in the country has been generally lacking dating as far back as 1995. During the period 1989 to present, Kenya's Regulatory Authority, the Radiation Protection Board, undertook to provide personal monitoring, quality assurance, radioanalysis, and equipment calibration. Over the years these services have stalled due to outdated equipment most of which have broken down. A maintenance and calibration service for nuclear equipment is an expensive cross-boarder issue. Budgetary constraints, insufficient human and equipment resources, and a perennial 'brain drain' has placed limitations to the effectiveness and efficiency of implementation of the National programmes and slowed the

Combined with the present status of radioactive contamination and marine biodiversity in China seas, it is pointed out that non-human radiation protection should be considered on the bases of marine biodiversity protection. Besides, the reference species for marine radiation protection and some viewpoints on the work of marine radiation protection in China are pro- posed. (authors)

  16. Basic standards for radiation protection

    International Nuclear Information System (INIS)

    Webb, G.A.M.

    1982-01-01

    The basic standards for radiation protection have been based, for many years, on the recommendations of the International Commission of Radiological Protection. The three basic standards recommended by the Commission may be summarized as ''justification, optimization of protection and adherence to dose limitations. The applications of these basic principles to different aspects of protection are briefly summarized and the particular ways in which they have been applied to waste described in more detail. The application of dose limits, both in the control of occupational exposure and in regulating routine discharges of radioactive effluents is straight forward in principle although the measurement and calculational requirements may be substantial. Secondary standards such as derived limits may be extremely useful and the principles underlying their derivation will be described. Optimization of protection is inherently a more difficult concept to apply in protection and the various techniques used will be outlined by with particular emphasis on the use of cost benefit analysis are recommended by the ICRP. A review will be given of the problems involved in extending these basic concepts of the ICRP to probabilistic analyses such as those required for assessing the consequences of accidents or disruptive events in long term repositories. The particular difficulties posed by the very long timescales involved in the assessment of waste management practices will be discussed in some detail. (orig./RW)

  17. The Radioecological Aspects OF Radiation Protection

    International Nuclear Information System (INIS)

    Branica, G.; Franic, Z.; Marovic, G.

    2015-01-01

    This paper discusses the links between radioecology and radiation protection. The traditional radiation protection framework of the International Commission Radiological Protection (ICRP), adopted by the legislation of most countries, is shifting from the paradigm that 'if man is adequately protected from ionizing radiation, then other living things are also likely to be sufficiently protected' towards more efficient protection of non-human biota. However, the estimation of radiation doses, especially low ones, to non-human organisms is very complex issue since they have been studied to a far lesser extent compared to human doses. The first step in dose calculations (i.e. risk assessment) is the measurement of real field data for various radionuclides in various compartments of the biosphere as well as dose rate measurements. Once we obtain relevant data, it is reasonable to argue that biota is adequately protected if the dose rates to the maximally exposed individual from this population are below a certain (safe) limit. The problem arises when one attempts to identify such an individual within a contaminated environment described by measured radioecological parameters. Computer simulation techniques, like Monte Carlo methods are used to generate a 'population' of doses with known distributional qualities. Then, using statistical methods, a part of this population is mathematically 'sampled' to compare the ability of the various statistics at estimating the representative sample of maximally exposed individuals. This exposure, depending on environmental conditions is subject to radioecological investigations. Radioecological investigations regarding fission products in Croatia are implemented as part of an extended and still ongoing radioactive contamination monitoring programme of the human environment that has been fully harmonized with European legislation, i.e. the European Commission's recommendation of June 2000 on the

    The Role of Radiotherapy is treatment modalities for cancer which is generally assumed that 50 to 60% of cancer patients will benefit from radiotherapy. It constitutes a peaceful application of ionizing radiation and an essential part of cancer management. The two aims of radiation protection Prevention is of deterministic effect and Reduction of the probability of stochastic effects. The Shielding fundamentals is to limit radiation exposure of staff, patients, visitors and the public to acceptable levels it also optimize protection of patients, staff and the public. Diagnosis is important for target design and the dose required for cure or palliation while Simulator is often used twice in the radiotherapy process where Patient data acquisition - target localization, contours, outlines and Verification. The Prescription is the responsibility of individual clinicians, depending on the patient’s condition, equipment available, experience and training. An ultimate check of the actual treatment given can only be made by using in vivo dosimetry. Treatment records must be kept of all relevant aspects of the treatment – including Session and Summary Record information, Records all treatment parameters, Dose Calculations and Dose Measurements

    Radiation exposure control is one of the most important aspects in any nuclear facility . It encompasses continuous monitoring of the various areas of the facility to detect any increase in the radiation level and/or the air activity level beyond preset limits and alarm the O and M personnel working in these areas. Detection and measurement of radiation level and the air activity level is carried out by a number of monitors installed in the areas. These monitors include Area Gamma Monitors, Continuous Air Monitors, Pu-In-Air Monitors, Criticality Monitors etc. Traditionally, these measurements are displayed and recorded on a Central Radiation Protection Console(CRPC), which is located in the central control room of the facility. This methodology suffers from the shortcoming that any worker required to enter a work area will have to inquire about the radiation status of the area either from the CRPC or will get to know the same directly from the installed only after entering the area. This shortcoming can lead to avoidable delays in attending to the work or to unwanted exposure. The authors have designed and developed a system called Distributed Radiation Protection Console (DRPC) to overcome this shortcoming. A DRPC is a console which is located outside the entrance of a given area and displays the radiation status of the area. It presents to health physicist and the plant operators a graphic over-view of the radiation and air activity levels in the particular area of the plant. It also provides audio visual annunciation of the alarm status. Each radioactive area in a nuclear facility will have its own DRPC, which will receive as its inputs the analog and digital signals from radiation monitoring instruments installed in the area and would not only show those readings on its video graphic screen but will also provide warning messages and instructions to the personnel entering the active areas. The various DRPCs can be integrated into a Local Area Network, where the

    1999-01-01

    A brief overview is given on the educational courses containing topics in the field of radiation protection in the Tallinn Technical University and in the University of Tartu, Estonia. It follows from the analysis that at present there is no complete system for education or training of experts in the field. At the same time a significant deficit in specialists and experts is one of the major barriers in the development of an efficient radiation protection infrastructure in this country. A comparison of the course topics to the syllabus for the training of qualified experts recommended by EC and by IAEA demonstrates the items, which need a further development and an expanded coverage in the existing or in future courses. These items involve, e.g., operational radiation protection and its organisation, waste management, transport, quality assurance, etc. Upgrading of courses for the missing theoretical items is not difficult, but it is not sufficient. The largest void lies in the weakness / absence of an adequate basis for practical work or exercises for students. The examples of co-operation and help provided for the existing courses, especially by the Nordic countries, are encouraging. (au)

    Though a century old, the radiation protection is actual by its purpose: a dose as low as reasonable achievable is to be received either by involved professionals or population. This threshold is dependent on the technical progress. Some major developments like surface mounted device technology, consumer almost ideal operational amplifiers, microcontrollers and the news signal digital processing techniques, offer the opportunity to design improved instruments for radioprotection. To put in a light portable instrument both the whole measuring system and the 'intelligence' - a microcontroller and the associated software - are the main ideas applied by the authors. The result is presented: a family of eight members, at least, based on two parents. (authors)

    European Commission Directive No. 2013/59 / EURATOM laying down basic safety requirements for the provision of radiation protection regulates the provision of radiation protection for workers with radiation sources and residents in all areas of use of ionizing radiation sources. This Directive also addresses radiation protection in the use of ionizing radiation sources in medicine. The European Commission Directive regulates the requirements for radiation protection but also extends to its scope and provisions on the use of medical radiation sources (so-called m edical exposure ) in the scope of further legislation in the field of health care, which has to be amended and modified or possibly issued new. It was necessary in the preparation of the new act on radiation protection to amend simultaneously Act no. 576/2004 on the provision of health care and services related to provision of health care and Act no. 578/2004 on Health care Providers, Health care Professionals and Organizations in Health Care and to prepare a series of implementing regulations not only to the Law on Radiation Protection but also to the Laws governing the Provision of Health Care. The paper presents changes to existing legislation on radiation protection in medical radiation and new requirements for the construction and operation of health workplaces with radiation sources, the protection of the health of patients, the requirements for instrumentation used for medical radiation and radiological instrumentation tests.

    This study investigates how, from a legal point of view, deviations in radiation protection measurements should be treated in comparisons between measured results and limits stipulated by nuclear legislation or goods transport regulations. A case-by-case distinction is proposed which is based on the legal concequences of the respective measurement. Commentaries on nuclear law contain no references to the legal assessment of deviating measurements in radiation protection. The examples quoted in legal commentaries on civil and criminal proceedings of the way in which errors made in measurements for speed control and determinations of the alcohol content in the blood are to be taken into account, and a commentary on ozone legislation, are examined for analogies with radiation protection measurements. Leading cases in the nuclear field are evaluated in the light of the requirements applying in case of deviations in measurements.

    Approximately 90% of the Secondary Standard Dosimetry Laboratories (SSDLs) provide users with calibrations of radiation protection instruments, and the Agency is making every necessary effort to insure that SSDLs measurements in radiation protection are traceable to Primary Standards. The IAEA provides traceable calibrations of ionization chambers in terms of air kerma at radiation protection levels and ambient dose equivalent calibrations. SSDLs are encouraged to use the calibrations available from the Agency to provide traceability for their radiation protection measurements. Measurements on diagnostic X ray generators have become increasingly important in radiation protection and some SSDLs are involved in such measurements. The IAEA has proper radiation sources available to provide traceable calibrations to the SSDLs in this field, including an X ray unit specifically for mammography dedicated to standardization procedures. The different photon beam qualities and calibration procedures available in the Agency's Dosimetry Laboratory will be described. (author)

    2004-01-01

    The present concept of dosimetric radiation protection quantities for external radiation is reviewed. For everyday application of the concept some adaptations are recommended. The check of the compliance with dose limits should be performed either by the comparison with values of the respective operational quantities directly or by the calculation of the protection quantity by means of the operational quantity, the appertaining conversion coefficient and additional information of the radiation field. Only four operational quantities are regarded to be sufficient for most applications in radiation protection practice. The term equivalent should be used in the connection dose equivalent only. Proposals are made for names of frequently used operational quantities which are denoted up to now by symbols only. (authors)

    During the operation of nuclear power plants it is normally possible for the in-house personnel to take care of arising radiation protection problems. However, in the comparatively short revision phases, the duties of radiation protection become much more varied. Additional trained radiation protection crews are needed at short notice. This is also the time in which the largest contributions are made to the annual cumulated doses of the personnel. Recent guidelines and rules trying to reduce the radiation exposure of personnel concentrate on this very point.

    Various conversion coefficients have been used in external and internal dosimetry in radiation protection practices. Radiation doses in the human body cannot be directly measured in general situation and the conversion coefficient has been used to correlate the human body dose with physical quantities such as radioactivity, particle fluence and other dosimetric quantities to be used to describe the radiation field. Fluence-to-organ dose conversion coefficients have been calculated using Monte Carlo radiation transport codes in conjunction with an anthropomorphic mathematical phantom. Neutron and photon interaction cross-section libraries are indispensable for these calculations. ICRP Publication 74 gives tables of conversion coefficients for estimation of organ doses and effective dose for photons, neutrons and electrons. Based on these results, shielding calculation parameters have been prepared for simple and easy dose estimation in radiation facilities. Dose factors, organ doses and effective dose per unit intake of radionuclide, have been also calculated for internal dosimetry purpose. ICRP Publications 68 and 72 give tables of dose factors for a variety of radionuclides. Revision of radiation data library has been made to reflect updated information on radionuclides to internal dosimetry. (author)

  12. Radiation protection of non-human species

    The effects of radiation on non-human species, both animals and plants, have long been investigated. In the disposal of radioactive wastes, the protection of non-human species has been investigated. Yet no radiation protection standard for exposure of animals and plants per se has been agreed. The International Commission on Radiological Protection has long taken the view that, if human beings are properly protected from radiation, other species will thereby be protected to the extent necessary for their preservation. However, the International Atomic Energy Agency has found it necessary to investigate the protection of non-human species where radioactivity is released to an environment unpopulated by human beings. It is proposed that the basis of such protection, and the knowledge of radiation effects on non-human species on which it is based, suggest a practical radiation protection standard for non-human species.

    Full text: The goal of this paper is to identify the areas in which radiation protection is actually needed and the relative importance of protection measures. A correlation between the different medical applications of the ionizing radiations and the associated risks, mainly due to ignorance, has been a constant throughout the history of mankind. At the beginning, the accidents were originated in research nuclear laboratories working on the atomic bomb, while the incidents occurred in medical areas because of virtual ignorance of the harmful effects on humans. The 60's were characterized by the oil fever, which produced innumerable accidents due to the practice of industrial radiography; in the 70's the use of radiations on medical applications was intensified, to such and extent that a new type of victim appeared: the patient. Unfortunately, during 80's and 90's the number of accidents in different medical practices has increased, projecting the occurred in Zaragoza (Spain) on 1990 with a linear accelerator for radiotherapy treatments. In some developed countries, foreseeing the probability of producing biological effects as a result of different radiology practices, more strict security rules are adopted to guarantee the application of the three principles of the radioprotection: justification, optimization and limitation of individual dose. In this way, in the U.S.A., the Joint Commission on Accreditation of Health Care Organization (JCAHO), favors a vigilance politics in the different departments of Radiodiagnostic and Nuclear Medicine to secure an effective management in security, communications and quality control, in which the medical physicists play an important role. One of the requirements for example is to attach the value of entrance exposition dose in the radiological diagnostic report. So, the doses in the different organs are compared with the tabulated doses. Basically, a quality control programme is designed to minimize the risks for patients

    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)

    Title 10 Code of Federal Regulations (CFR) Part 835, “Occupational Radiation Protection,” establishes radiation protection standards, limits, and program requirements for protecting individuals from ionizing radiation resulting from the conduct of U.S. Department of Energy (DOE) activities. 10 CFR 835.101(a) mandates that DOE activities be conducted in compliance with a documented Radiation Protection Program (RPP) as approved by DOE. This document promulgates the RPP for the Nevada National Security Site (NNSS), related (on-site or off-site) U.S. Department of Energy, National Nuclear Security Administration Nevada Field Office (NNSA/NFO) operations, and environmental restoration off-site projects. This RPP section consists of general statements that are applicable to the NNSS as a whole. The RPP also includes a series of appendices which provide supporting detail for the associated NNSS Tennant Organizations (TOs). Appendix H, “Compliance Demonstration Table,” contains a cross-walk for the implementation of 10 CFR 835 requirements. This RPP does not contain any exemptions from the established 10 CFR 835 requirements. The RSPC and TOs are fully compliant with 10 CFR 835 and no additional funding is required in order to meet RPP commitments. No new programs or activities are needed to meet 10 CFR 835 requirements and there are no anticipated impacts to programs or activities that are not included in the RPP. There are no known constraints to implementing the RPP. No guides or technical standards are adopted in this RPP as a means to meet the requirements of 10 CFR 835.

    1984-01-01

    The objective of the new Act is to protect humans, animals and the environment from the harmful effects of ionizing as well as non-ionizing radiation. As previously, the main responsibility for public radiation protection will rest with a single central radiation protection authority. According to the Act, the general obligations with regard to radiation protection will assign greater responsibility than in the past to persons carrying out activities involving radiation. Persons engaged in such activities will be responsible for the safe processing and storage of radioactive waste. The Act also contains rules governing decommissioning of technical equipment capable of generating radiation. The Act contains several rules providing for more effective supervision. The supervisory authority may, in particular, decide on the necessary regulations and prohibitions for each individual case. The scope for using penal provisions has been extended and a rule on the mandatory execution of orders regarding radiation protection measures has been introduced. (authors)

    1980-01-01

    Various governmental agencies, including the Ministry of Health, the Ministry of Labor and the Israel AEC are responsible for the control of the use of radioactive materials and medical X-ray machines in Israel. Present legislation deals mainly with the legal aspects of the purchase, transport and possession of radioactive materials and the purchase and operation of medical X-ray machines. No legislation refers explicitly to the protection of the worker from ionizing (and non-ionizing) radiation. A special group of experts appointed by the Minister of Labor recently worked out a comprehensive draft law concerning all legal aspects of occupational radiation protection in Israel. Among the main chapters of the draft are: general radiation protection principles, national radiation protection standards, medical supervision of radiation workers, personal monitoring requirements. The present situation with regard to radiation hazard control in Israel and details of the proposed radiation protection law is discussed. (Author)

    The ratio benefit/risk of radiological examinations, especially with the multislice scanner cannot be ensured only if the principles of justification and optimization are rigorously respected. The justification relies on the reference to the guide of the appropriate use of imaging examinations and compliance with the Public Health Code which requires a written information exchange between the applicant and who will realizes the examination. The optimization relies on the dosimetry evaluation of our practice and the comparison with the diagnosis reference levels, to realize the examinations at the radiation lowest cost. the stakes are the insurance does not harm our patients, the rehabilitation of the radiologist in his role of consultant rather than performer and the protection against eventual legal consequences.

  4. New general radiation protection training course

    CERN Document Server

    2008-01-01

    Some members of CERN personnel, users included, may have to work in supervised or controlled radiation areas, or may be concerned with activities involving the use of radioactive sources. According to CERN Safety rules all persons whose work may encounter ionising radiation risk must be adequately trained. This training must ensure that workers are informed about the potential health risks which could result from radiation exposure, about the basic principles of radiation protection and of the relevant radiation protection regulations as well as about safe working methods and techniques in radiation zones. Therefore the Organization organises mandatory general and work-specific radiation protection (RP) courses addressed to its personnel. These courses are also open to contractors’ personnel, in addition to the RP training they must receive from their employers. Based on the results of a pilot project, an improved general radiation protection course has been prepared. This...

    Based on the high technical status of radiation protection the occupational exposure of radiological personnel is no more of predominant importance. No defined dose limits exist for patients in the frame of therapeutic applications in contrary to the radiological personnel. As a consequence walk-downs radiotherapeutic institutions twice the year have been initiated in order to guarantee a maximum of radiation protection for patient's treatment. An actualization of radiation protection knowledge of the radiological personnel is required.

    2004-01-01

    Radiation protection in a university institute operating a research reactor and other installations has different constraints as a larger facility. This is because the legal requirements apply in full, but the potential of exposure is low, and accesses has to be made available for students, but also for temporary workers. Some of the problems in practical radiation protection are addressed and solutions are discussed. In addition, experience with national radiation protection legislation recently to be issued is addressed and discussed. (author)

    Hola, O.; Holy, K.

    2005-01-01

    In our contribution we want to outline our plan of actions to be carried out for the creation of the first multimedia internet textbook in Slovakia in the field of ionizing radiation and radiation protection. In particular we want to describe first steps that have been performed at its realisation. This textbook would be applicable to the full-time study as well as to distance learning at traditional universities and technical universities. It will also be usable for various forms of in-service training by e-learning. Our objective is to create a modem internet textbook in radiation protection, of which production will be co- ordinated with other European Union countries. The output of our project -the multimedia textbook -will be available to all students at our university's servers and other users will have CDs at their disposal. We propose the use of this multimedia didactic means also in various forms of the distance e-learning. The main motivation for the implementation of distance courses is the necessity to update knowledge, skills and qualification in our contemporary rapidly developing world. The distance e-learning form of education can solve also the problem with the acquisition of the professional qualifications for the work with ionizing radiation. This is the reason for usage of the mentioned textbook not only as the fundamental and unified textbook for the students of universities, but also as the study material for the civil servants responsible for radiation protection, for in-service workers and providers of the professional training.

    The work scope of Biological research for the radiation protection had contained the search of biological microanalytic methods for assessing the health effect by {gamma}-radiation and toxic agents, the standardization of human T-lymphocyte cell culture and polymerase chain reaction, T-cell clonal assay, and the quantification of mutation frequency in the hypoxanthine (guanine) phosphoribosyl transferase (HPRT) gene locus by single exposure or combined exposure. Especially, the polymerase chain reaction methods using reverse transcriptase has been developed to analyze the mutant gene induced by {gamma}-radiation and chemical (pentachlorophenol) agent exposure, and to investigate the point mutations in the HPRT gene locus of T-lymphocytes. The HPRT T-cell clonal assay revealed that it could not differentiate {gamma}-irradiation from pentachlorophenol, because the frequency of somatic mutations induced by both damaging agents increased in a dose-dependent manner. The analysis of DNA sequence alterations of HPRT mutant clones clearly showed that both damaging agents induced different mutational spectra in the HPRT locus of T-cells. The large deletions, which account for 75 percent of the analyzed mutants, are characteristic mutations induced by {gamma}-irradiation. By contrast, point mutations such as base substitutions and insertion, come up to 97 percent in the case of pentachlorophenol-treated cells. The point mutation frequencies at 190 base pair and 444 base pair positions are 3-6 folds as high as in those at other mutation positions. It may be that these mutation sites are hot spots induced by pentachlorophenol. These results suggest that the HPRT mutation spectrum can be used as a potential bio marker for assessing a specific environmental risk. (author)

    Two newly developed radiation protection devices for urological working stations are presented. The local dose to which doctor and assisting personnel are exposed during fluoroscopy and radiography was measured and the radiation burden with and without radiation protection determined. The studies show that without these devices organs such as the eyes are exposed, at a normal working distance from the table, to such an amount of scattered radiation as to reduce the permitted number of examinations per week.

    Quality management and continuous improvement systems are becoming part of daily health services, including radiodiagnostic services, which are designed to meet the needs of users, operating in an environment where the differential is due to the competence and quality of the services provided. The objective of this study is to show the scope of the management of health services, especially radiodiagnosis and radiological protection. Method: Exploratory and descriptive study, based on a review of the literature on the subject. Results: Radiodiagnosis has demonstrated the need for efficient management, especially because ionizing radiation is present in this environment and it is imperative that the professionals working in this area are aware of the need to perform adequate radiological protection for themselves and for users. Conclusion: Universal access to information has changed the attitude of the user and the user has become more demanding in his choices, wanting to understand, express, interact and choose the best quality service in view of the various options available in the market

  16. The new operational quantities for radiation protection

    International Nuclear Information System (INIS)

    Kellerer, A.M.

    1985-01-01

    Philosophies and quantities for radiation protection have often been subjected to changes, and some of the developments are traced which ultimately led to recent proposals by ICRU. Development in the past has largely been towards clarification and generalisation of definitions. The present changes, however, reflect a more fundamental issue, the transition from the limitation system to the assessment system in radiation protection. The index quantities were suitable tools to ascertain compliance with the limitation system of radiation protection. The new quantities proposed by ICRU are suitable estimators for effective dose equivalent, which is an essential quantity in the assessment system of radiation protection. A synopsis of the definitions is given. (author)

    The status of radiation protection practices in Asian countries is monitored by different means, e.g. the IAEA technical cooperation activities, by an overall assessment of conditions in a country by RAPAT missions, and on the basis of data collected through various regional activities. The radiation protection situation in Asia is very heterogeneous. There is a group of countries with very well developed radiation protection practices and advanced in the application of the Basic Safety Standards, but the majority of Asian member states still need improvement, several lacking the necessary fundamental infrastructure for radiation protection

    A research covering 91 institutions was undertaken in order to elucidate how radiation protection were indeed fulfilled. A questionary including technical administrative and legal subjects was sent by mail and 36% of which were answered propitiating substantial data for analysis. Only in few cases universities have knowledge of basic procedures in radiation protection, claiming for the elaboration of a plan that could guide supervisors and workers in radiation protection in these institution. Based on the tree analysis technique proposed by IAEA, a Reference Radiation protection Program has been elaborated and proposed for Brazilian universities. (author). 14 refs, 1 figs

  2. Basic principles of radiation protection in Canada

    International Nuclear Information System (INIS)

    1990-03-01

    The major goal of radiation protection in Canada is to ensure that individuals are adequately protected against the harm that might arise from unwarranted exposure to ionizing radiation. This report deals with the basic principles and organizations involved in protection against ionizing radiation. Three basic principles of radiation protection are: 1) that no practice shall be adopted unless its introduction produces a positive net benefit for society, 2) that all exposures shall be kept as low as reasonably achievable, relevant economic and social factors being taken into account, and 3) that doses to individuals should not exceed specified annual limits. The limit for radiation workers is currently 50 mSv per year, and exposures of the general public should not exceed a small fraction of that of radiation workers. Other specific areas in radiation protection which have received considerable attention in Canada include limitations on collective dose (the sum of the individual doses for all exposed individuals), exemption rules for extremely small radiation doses or amounts of radioactive materials, occupational hazards in uranium mining, and special rules for protection of the foetus in pregnant female radiation workers. Implementation of radiation protection principles in Canada devolves upon the Atomic Energy Control Board, the Department of National Health and Welfare, provincial authorities, licensees and radiation workers. A brief description is given of the roles of each of these groups

    In radiation protection measurements signals from radiation detectors or dosemeters have to be transformed into quantities relevant to radiation protection. In most cases this can only be done by taking into account various parameters (e.g. the quality factor). Moreover, the characteristics of the statistical laws of nuclear radiation emission have to be considered. These problems can properly be solved by microprocessors. After reviewing the main properties of microprocessors, some typical examples of applying them to problems of radiation protection measurement are given. (author)

    The space missions on orbital stations are becoming longer and the radiological risk constitutes a factor limiting the space flights. The tissue-equivalent proportional counters, (CIRCE in 1988 and 1990, then NAUSICAA from 1992), have been conceived to ensure the monitoring and the dosimetry of space travellers. They measure in real time, different parameters of dosimetry and evaluate the microdosimetric spectrum of space radiations on the board of the Mir spatial station. The equivalent of middle day dose measured by CIRCE was situated between 0.6 and 0.8 mSv associated to a quality factor of 1.9; that one measured by NAUSICAA is higher, between 0.9 and 1.0 mSv with a steady quality factor. These systems measure the time and spatial variations of cosmic radiations, in function of solar activity, orbit, and shielding thickness of space vehicles. Values of high doses equivalent (upper than 1 mSv), associated to quality factor of 1.4 have been measured during the South Atlantic Anomaly crossing and during solar eruptions. That is the same for polar regions. The evaluation of Relative Biological Effectiveness (R.B.E.) of the space radiations on Mir station board, in term of carcinogenesis of the Harder gland in the mouse, is here an extrapolation of a relation based on experimental data; the average R.B.E. allows to suppose that radiological risk is low.

    While ionizing radiations have significant and indispensable uses in several fields, it must be borne in mind that it may be harmful to the radiation workers and public if used indiscriminately and without due caution. Radiation doses received by these individuals should be kept well within the recommended limits through good work practices. It is therefore necessary to ensure safety of radiation workers, patients undergoing radiation diagnosis and treatment, public and environment so that maximum benefit is derived from the use of radiation with minimum and acceptable risk. General principles of radiation protection and safety in various applications of radiations are discussed

    2017-04-01

    Reflecting the change in funding strategies for European research projects, and the goal to jointly improve medical radiation protection through sustainable research efforts, five medical societies involved in the application of ionising radiation (European Association of Nuclear Medicine, EANM; European Federation of Organizations for Medical Physics. EFOMP; European Federation of Radiographer Societies, EFRS; European Society of Radiology, ESR; European Society for Radiotherapy and Oncology, ESTRO) have identified research areas of common interest and developed this first edition of the Common Strategic Research Agenda (SRA) for medical radiation protection. The research topics considered necessary and most urgent for effective medical care and efficient in terms of radiation protection are summarised in five main themes: 1. Measurement and quantification in the field of medical applications of ionising radiation 2. Normal tissue reactions, radiation-induced morbidity and long-term health problems 3. Optimisation of radiation exposure and harmonisation of practices 4. Justification of the use of ionising radiation in medical practice 5. Infrastructures for quality assurance The SRA is a living document; thus comments and suggestions by all stakeholders in medical radiation protection are welcome and will be dealt with by the European Alliance for Medical Radiation Protection Research (EURAMED) established by the above-mentioned societies. • Overcome the fragmentation of medical radiation protection research in Europe • Identify research areas of joint interest in the field of medical radiation protection • Improve the use of ionising radiation in medicine • Collect stakeholder feedback and seek consensus • Emphasise importance of clinical translation and evaluation of research results.

    1989-01-01

    Radiation protection is a highly international dicipline with a high degree of international harmonization. Especially within the Nordic countries there is general agreement upon principles and standards, despite the actual practice may differ slightly. The basic recommendations of the International Commission on Radiological Protection (ICRP) are accepted by the regulatory bodies and should be followed by all users of radiation. The users are in principle responsible for the radiation protection standard and activities themselves. Because most companies or hospitals lack sufficient expertise by themselves, they must rely upon recommendations from others. Primarily they should contact the national radiation protection agency. However, due to the international harmonization of radiation protection, information from other national or international agencies may be used with confidence. All users of radiation in the Nordic countries are obliged to act according to recognition and assessment of both risks and benefits, and they are responsible for updating their knowledge

    The International Community has established a dose limitation system to control the risks due to the ionizing radiation pacific use. The education and training of the occupational exposed workers is necessary to achieve the objectives of this dose limitation system.The second largest contribution to exposures of the individuals worldwide after natural background radiation, comes from medical radiation procedures. For this reason, the radiation protection training of medical workers is essential. In the particular autonomous region of Andalusia, most medical radiation procedures comes from the Public Health Service. Therefore, Andalusia Healthy Service maintains a radiation protection training plan for their occupational exposed workers. This training plan includes: training of the radioactive facilities supervisors and operators in both nuclear medicine and radiotherapy areas; training for medical radiodiagnosis facility management; quality assurance in medical diagnosis and therapy; and update on radiation protection. The training plan is performed with theoretical and practical course homologated by the Spanish Nuclear Safety Council. These courses cover four basic fields related to radiation: Physics, Radiobiology, Radiation Protection and Legislation. These courses have been organised by the Andalusia Healthy System since 1993. A total of 722 medical workers have been trained for radiation protection. Therefore, optimum conditions for the safe and correct use of ionizing radiation have been provided to these workers. The supervisor or operator's license of the radioactive facility can be also obtained by these courses. (Author) 17 refs

    Rules and regulations of federal agencies and state radiation protection programs provide the bases for hospital policy regarding radiation safety for nurses. Nursing administrators should work with the radiation safety officer at their institutions to ensure that radiation exposures to staff nurses will be as low as reasonably achievable and that special consideration will be given to pregnant nurses. Nurses' fears about their exposure to radiation can be greatly reduced through education

    On the basis of legally provided area dose measurements and time records of fluoroscopic examinations during the operation, radiation doses to medical personnel and patients are evaluated. Adequate radiation protection measures and a careful behaviour in the operating room keep the radiation exposure to the personnel below the maximum permissible exposure. Taking into account the continuous personnel radiation monitoring and medical supervision, radiation hazards in the operating room can be considered low

    Repeat hygienic investigation of the conditions of radiation protection in preventive screening of children's hips (at a time interval of 10 years) in the Central Bohemian Region revealed certain improvement in covering children's gonads (in the frequency of using protective devices), in the protection of the accompanying person and the equipment of the workplaces with modern X-ray apparatus and automatic developers. Large differences between individual workplaces were seen in the selection of technical parameters (voltage, power, focus, size of irradiated field); that is why up to nine-fold differences existed in irradiation of children. (The mean gonadal dose was 22.6 μGy and the mean weighted whole-body dose was 71.2 μGy.) A conservative estimate of the effective dose equivalent was used in comparing the social cost and benefit in preventive screening of children's hips which had shown that at least one preventive X-ray picture in all children in the 3rd to 4th month after birth was quite reasonable. The analysis of the problems outlined revealed that particular attention must be paid to the protection of the children's gonads by using suitable protective devices and to minimize irradiation of children by a suitable adjustment of technical parameters of the examination and also by exclusive use of quality film material.

    Full text: Boron Neutron Capture Therapy (BNCT) is a technique that selectively targets cancer cells while sparing normal tissues by virtue of the differential uptake of a 10 B carrier compound in tumor. The National Atomic Energy Commission (CNEA) and the Oncology Institute 'Angel H. Roffo' (IOAR) began a BNCT programme in 2003 for treating cutaneous skin melanomas in extremities. The neutron beam used is the hyperthermal one developed at the RA-6 Reactor of the Bariloche Atomic Centre (CAB). The prescribed dose is delivered in one fraction and therefore patient positioning and knowledge of the dose received by normal tissue are crucial. 10 irradiations have been done since 2003, all of them in legs and feet and the dose prescription was determined by the maximum tolerable skin dose. Due to the characteristics of this treatment the patient body might be exposed not only to the primary beam but also to the secondary photon beam produced by neutron capture at the target itself. Thus a patient radiation-monitoring plan was implemented in order to evaluate the gamma dose delivered to sensible organs of each patient. An acrylic water-filled whole body phantom was used for preliminary gamma dose and thermal neutron flux measurements at positions related to patient's body sensible organs considering tentative patient positions. The beam port shielding was, in this way, optimized. TLD-700 and Manganese foils were used for gamma and thermal neutron detection. The TLD-700 thermal neutron response was previously evaluated by using the in-phantom beam dosimetry characterization. In-vivo dosimetry with TLD is routinely implemented in order to evaluate gamma dose to sensible organs of each patient. These organs are chosen depending on its distance from the zone to be irradiated and its radio-sensibility. All TLDs have been positioned well outside the irradiation field. Maximum gamma dose received outside the radiation field in healthy tissues was well below tolerance dose for

    1990-01-01

    This document aims to trace the evolution of the CEC radiation protection programme over its 30 years of existence. During this time, research carried out in the framework of the Community programme has made major contributions to the scientific understanding of the action of ionizing radiation and the protection of man and his environment. This information was crucial for developing better radiation protection management for existing and new technologies and for providing the scientific basis for the regulatory activities of the Commission. One important feature of the programme was the success of bringing together scientists from different Member States to cooperate in the various fields of radiation protection and to integrate different areas of radiation protection research into a coherent approach. The structures thus developed within the programme have enabled research in radiation protection to be conducted in a cost-effective manner on behalf of the Member States. This document aims also to give a synopsis of the most important results of the 1985-89 radiation protection programme. This period was characterized by two challenges, the integration of two Member States into Community research and the impact of the Chernobyl accident. The programme has, in spite of reduced funding, continued to provide a high degree of expertise for the Community in the context of the needs in radiation protection. This has been explicity acknowledged in the evaluation of the 1980-89 programmes carried out by an independent panel

  10. Quality of radiation field imaging

    International Nuclear Information System (INIS)

    Petr, I.

    1988-01-01

    The questions were studied of the quality of imaging the gamma radiation field and of the limits of the quality in directional detector scanning. A resolution angle was introduced to quantify the imaging quality, and its relation was sought with the detection effective half-angle of the directional detector. The resolution angle was defined for the simplest configuration of the radiation field consisting of two monoenergetic gamma beams in one plane. It was shown that the resolution angle decreases, i.e., resolution in imaging the radiation field is better, with the effective half-angle of the directional detector. It was also found that resolution of both gamma beams deteriorated when the beams were surrounded with an isotropic background field. If the beams are surrounded with a background field showing general distribution, the angle size will be affected not only by the properties of the detector but also by the distribution of the ambient radiation field and the method of its scanning. The method described can be applied in designing a directional detector necessary for imaging the presumed radiation field in the required quality. (Z.M.). 4 figs., 3 refs

    This document proposes a large and detailed overview of notions and practices regarding radiation protection in relationship with an NPP exploitation framework. It presents the main notions: matter structure, radioactivity, interactions between matter and radiations, types of ionizing radiation, magnitudes and measurement units, exposure modes, main principles of radiation protection, means of protection against internal and external exposures. The second part proposes an overview of the origin of radiological risks in a nuclear power plant. This origin can be found in fission products, activation products, actinides, designed protections, or circuit contaminations. These radiological risks are more precisely identified and described in terms of detection and prevention (internal exposure risk, contamination risk, iodine-related risk, alpha radiation-related risk, access to the reactor building). The next part addresses the medical and radiological follow-up of exposed workers by a special medical control, by an individual exposure control, by a specific control of female personnel, and by attention to exceptional exposures. Measurement means are presented (detection principles, installation continuous control, workspaces control, personnel contamination control, follow-up of individual dose) as well as collective and individual protection means. The management of radiation protection is addressed through a presentation of decision and management structures for radiation protection, and of EDF objectives and ambitions in this domain. The organization of radiation protection during exploitation is described: responsibilities for radiation protection in a nuclear power station, requirements for workers, preparation of interventions in controlled zone, work execution in controlled zone, zone controls and radiological cleanness of installations. The two last chapters address issues and practices of radiation protection in the case of deconstruction or dismantling, and

    Fry, R.J.M.

    1987-01-01

    The original recommendations for radiation protection guidelines were made by the National Academy of Sciences in 1970. Since that time the US crews have become more diverse in their makeup and much has been learned about both radiation-induced cancer and other late effects. While far from adequate there is now some understanding of the risks that high-Z and -energy (HZE) particles pose. For these reasons it was time to reconsider the radiation protection guidelines for space workers. This task was undertaken recently by National Council on Radiation Protection (NCRP). 42 refs., 2 figs., 9 tabs

    In order to protect humans and the environment when using ionizing radiation for the advancement and benefit of society, accurately quantifying radiation and its potential effects remains the driver for ensuring the safety and secure use of nuclear and radiological applications of technology. In the realm of radiation protection and its various applications with the nuclear fuel cycle, (nuclear) medicine, emergency response, national defense, and space exploration, the scientific and research needs to support state and federal radiation protection needs in the United States in each of these areas are still deficient.

    For the ecologists of the 1960s, the presence in the biosphere of fission products originating from nuclear explosions provided a wealth of opportunity for observation and experiment, for they were able to trace the paths of numerous radioactive substances in the atmosphere, immediate environment and eco-systems, and to determine the way in which these substances were metabolized in living organisms. Moreover, nuclear techniques such as the use of radioactive tracers, autoradiography and neutron activation afforded a means of determining the mechanisms by which the biologically significant radionuclides take effect and the processes by which they are transferred. Because of the comprehensive information that it can provide for analysis, radioecology has risen above its status as a pure science and has become an integral part in the planning of monitoring programmes for nuclear sites- Radioecology is thereby able to make an essential contribution to the attainment of one of the basic objectives of radiation protection, namely the elimination or control of the hazards that human beings and their environment are likely to be face through the peaceful applications of nuclear energy. The headway made in radioecological studies and research has been great; knowledge is being amassed by leaps and bounds despite the difficulties faced and the intricacy of the problems involved. As a consequence, radioactive contamination of the environment is certainly one of the best understood types of pollution, and probably one that it has so far been possible to anticipate and control under optimum conditions and with the most gratifying results.

    It a a great number of medical installations in spain using particle accelerators for radiotherapy. It is obvious the importance of an accurate estimation of the doses produced in these installations that may be received by health workers, patients or public. The lower values of dose limits established in the new ICRP recommendations imply a recalculation of items concerning such installations. In our country, specific guidelines for radiation protection in particle accelerators facilities have not been yet developed, however two possible guides can be used, NCRP report number 51 and DIN Standard 6847. Both have been analyzed comparatively in the paper, and major remarks have been summarized. Interest has been focused on thickness estimation of shielding barriers in order to verify whether must be modified to comply with the new dose limits. Primary and secondary barriers for a Mevatron used in a Medical Center, have been calculated and the results have been compared with actual data obtained from the installation, to test the adequacy of shielding barriers and radioprotection policies. The results obtained are presented and analyzed in order to state the implications of the new ICRP recommendations. (author)

    DEFF Research Database (Denmark)

    Zetner, D.; Andersen, L. P H; Rosenberg, J.

    2016-01-01

    Introduction: Radiation is widely used in the treatment of various cancers and in radiological imaging procedures. Ionizing radiation causes adverse effects, leading to decreased quality of life in patients, by releasing free radicals that cause oxidative stress and tissue damage. The sleep......-hormone melatonin is a free radical scavenger, and induces several anti-oxidative enzymes. This review investigates the scientific literature on the protective effects of melatonin against exposure to ionizing radiation, and discusses the clinical potential of melatonin as prophylactic treatment against ionizing...... and protected against radiation enteritis. These protective effects were only documented when melatonin was administered prior to exposure to ionizing radiation. Discussion: This review documents that melatonin effectively protects animals against injury to healthy tissues from ionizing radiation. However...

    1996-01-01

    Radiation protection and safety have developed over many decades as the effects of ionizing radiation have been better and better understood. Some events in the last decade had essential impact on radiation protection policy/philosophy and related safety standards. Among them are available data of some long term radio-epidemiological studies of populations exposed to radiation. Investigations of the survivors of the atomic bombing of Hiroshima and Nagasaki illustrated that exposure to radiation has also a potential for the delayed induction of malignancies. They also showed that irradiation of pregnant women may result with certain mental damage in foetus. Several big radiation accidents which appeared in the last decade also had an impact on developments in radiation protection philosophy and practices. A well known Chernobyl accident showed that limited knowledge was available at the time of the accident on transfer of radionuclides in a specific environment, radioecological effects and pathways of highly radioactive atmospheric precipitation generated during the accident on various components of the environment. New scientific data indicated also that in some parts of human environment there are measurable effects of chronic exposure resulting from natural radiation. UNSCEAR is periodically publishing the most valuable set of data as compilation, and disseminates information on the health effects of radiation and on levels of radiation exposure due to different sources. These data are also the best guidelines for the necessary improvements and updating of radiation protection practices and philosophies. The latest ICRP-60 publication and recently issued International Basic Safety Standards for Protection Against Ionizing Radiation and for the Safety of Radiation Sources are reflecting many of the above mentioned findings. On the other hand the use of radiation sources is increasing day by day, and many new facilities applying radiation in radiotherapy

  13. Comparison of Radiation Protection Training in European Countries

    International Nuclear Information System (INIS)

    Kozelj, M.

    2001-01-01

    Full text: Practice and implementation of radiation protection in European countries and in majority of other countries all over the world relies on common principles and recommendations established by international organisations. These principles and recommendations were incorporated in national legislation ensuring similar and compatible standards of protection for occupationally exposed workers and members of the public. One of the basic requirements derived from international recommendations is also formal request for training of occupationally exposed workers. The final goals of the training are defined only indirectly through standards of safety and protection. Therefore national regulation regarding radiation protection training in particular country is a result of general approach to education and training, historical circumstances, influence and importance of nuclear technology and other factors influencing health protection and national well-being in general. The result is variety of national regulations ranging from very stringent and detailed to rather general and flexible. Nevertheless, results of implemented training do not differ sufficiently to significantly affect achieved standards of radiation protection. According to available information European countries implement radiation protection training in dissimilar ways. Institutions and organisations involved, as well as form and duration of training varies from country to country. Therefore, it is not possible to determine common rules just by reviewing radiation protection training in different countries. It is the intention of this contribution to analyse and discuss available information regarding radiation protection training and point out the necessity of international co-operation in this field, especially in the sense of the future trends.

    In September 1991, the General Conference of IAEA, in the resolution GC/XXXV/RES/552 demanded the Director General to formulate the propositions in the field of education and teaching of radiation protection. After its meeting in 1993, the General Conference (document GC/XXXVII/1067) a program of education in radiation protection and nuclear safety. The IAEA has chosen L'Instut national des science et techniques nucleaires (INSTN) de Saclay, France, to perform the french training for its long-term education in nuclear field. During the nine weeks in May and June 1994, 24 participants from 22 countries attended 80 courses presented by 70 teachers. The organizers have attained a successful cooperation of competent French organizations in the field of radiation protection and nuclear safety as: Institut de protection et de surete nucleaire (IPSN), Commissariat a l'energie atomique (CEA), Compagnie generales des matieres nucleaires (COGEMA), Agence nationale pour la gestion de dechets radioactif (ANDRA), Office de protection contre les raynnements ionisants (OPRI), Electicite de France (EDF), as well as outstanding specialists in the medical field. The series of these lectures are presented in these two volumes. Admitting that the education and training in the field of radiation protection and nuclear safety are responsibilities of national authorities the IAEA hopes that this published material would be widely used by the Member States as a basis for their training programs in the mentioned field

    1997-01-01

    The Greek radiation protection Regulations were revised extensively and harmonized with the relevant Euratom Directives in 1991, covering almost all applications of ionizing radiation. According to the low in force, Greek Atomic Energy Commission (GAEC) is the regulatory and competent authority on radiation protection matters. Among others is responsible: for evaluating the environmental radiation, for introducing emergency plans to responsible Ministries to cope with radiation accidents or increased radioactivity levels, for issuing safety regulation concerning the operation employing ionizing radiation, performing inceptions to all installations or laboratories where radioisotopes or radiation producing machines are employed including all medical applications and issuing the certificate of compliance with the radiation protection regulations. GAEC is the governmental licensing authority for import, export, possession, use, transport and disposal of radioactive materials including fissile materials, and is also responsible for providing training and education to scientists and technical personnel on radiation protection and operates a two years postgraduate course in Medical radiation Physics in collaboration with three Greek Universities, leading to an M Sc degree.The achievements, initiatives and perceptivities of GAEC in the fields of its responsibility are discussed. Statistical data concerning the application of ionising radiation in Greece during the last five years are also presented (author)

    The first objective of the protection philosophy is to determinate the relation reason-effect in order to establish the exposition thresholds to acceptable values. To establish the radioprotection criteria is important to considerate the following: a-) The damage and effects of the non-ionizing radiation; b-) The physical aspects of the fields exposition; and c-) The dosimetry of the involucrate tissues. The non-ionizing radiation includes the optics radiations (ultraviolet, visible, infrared and laser), and the electromagnetic radiations (microwave, radars, magnetic and electrostatics fields)

    The German Society for Radiation Protection (in German Gesellschaft fur Strahlenschutz) is a separate society for radiation protection in Germany in addition to the leading society named Association of German and Swiss Radiation Protection Specialists (in German Fachverband fur Strahlenschutz). The Society is an international professional society. There are several hundreds members of the German Society for Radiation Protection. The German Society for Radiation Protection is not a member of IRPA (the International Radiation Protection Society). The IRPA member is the Association of German and Swiss Radiation Protection Specialists. According to information given on the web site of the Society for Radiation Protection (www.gfstrahlenschutz.de) the Society was founded in 1990 because in the opinion of the founding members the older professional societies and associations have not adequately considered and implemented the present knowledge of radiation risks and radiation protection. In accordance with its statutes the society pursues besides other aims the best possible protection of humans and the environment from the detrimental action of ionising and non-ionising radiation. The dealing with ionising and non-ionising radiation can according to the Society only be justified on the basis of biological and medical state of the art knowledge

    The 25th anniversary of the foundation of the Society of Nuclear Medicine and Radiation Hygiene is an opportunity for outlining the development in the field of radiation hygiene in Czechoslovakia. An integral system of radiation protection in Czechoslovakia involving a number of cooperating institutions is characterized. Specific tasks of radiation hygiene are fulfilled by Regional Hygiene Stations under the methodological guidance of the research institutes of the Ministries of Health of the Czech and Slovak republics. Another important problem of radiation hyaiene is the protection of health in respect to the impact of the nuclear fuel cycle; special attention is paid to reducing doses to the population due to radiodiagnostic procedures. Besides these highlights of its activity, radiation hygiene also controls the use of other sources of ionizing radiation in industry, agriculture and research. (author)

    In Hungary, radiation protection training for radiation workers has been introduced in very early, just following the publication of the ICRP recommendation No. 26. Before that, in some of the institutions, radiation protection training was recommended for technicians and medical doctors working in nuclear medicine, X-ray diagnostic radiology and radiation therapy, as well as in some of industrial applications, but not on regular way. Since 1988, radiation protection training regulated by the Ministry of Health and required for all of the workers in radiation workplaces licensed by the authority the State Public Health and Medical Officers Service (SPHAMOS). Decree No. 16/2000. (VI. 8.) EuM of the Minister of Health on the enforcement of Clauses of the Nuclear Law 116/1996 regulates the radiation protection training of Radiation Workers (RW). Annex 4 of Decree sees radiation protection training and in-service training: Persons performing conducted work in the field of the use of the nuclear energy and any other work within legal relationship shall be educated in training and in-service training at an interval of 5 years. Three levels of the training introduced; basic, extended and comprehensive, based on radiation risk related to the given job. Several institutions are involved in performing radiation protection training, such universities, scientific institutions, Regional Radiological Health Centers (RRHC) of SPHAMOS, private enterprises etc. All training course material is subject to accreditation. Most of the faculties of the universities involved in training of natural sciences and engineering provide subjects on the fundamentals of dosimetry, radiobiology and radiation protection within the courses of physics, biophysics, chemistry, biology, ecology etc. These courses take 5-10 contact hours per week on average. The members of the Hungarian Committee of EUTERP Platform summarize their broad experience collected in the past 20 year. (author)

    2003-01-01

    The effects of ionising radiation on man has been studied intensely for decades, and the system of radiation protection for man has been continually refined in the light of those studies. That system assumes that if man is protected, non-human biota at the species level will also be adequately protected. However, an increasing recognition of the need to protect the environment, and international agreements signed in 1992, have resulted in that paradigm being questioned, with the onus shifting slowly towards demonstrating that the environment is protected. Further, radiation protection agencies and environmental protection agencies around the world have now started considering the issue of developing a system of radiation protection for the environment. The International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA) are also active in this area. The purpose of this paper is to briefly outline some of the issues confronting environmental and radiation protection specialists, and to mention some of the initiatives being taken by the international community to resolve those issues

    Japanese and international standards related to radiation control and radiation protective management are presented focusing on the forming condition, significance, current situation, and their relationship. Japanese Industrial Standards (JIS) is quite useful in the field of atomic energy as well as other fields in terms of optimization and rationalization of the management. JIS includes JIS Z 4001 Atomic Energy Terminology which corresponds to internationl standards ISO 921 Nuclear Glossary, and JIS Z 4005 Medical Radiation Terminology, covering about 500 articles, which corresponds to IEC 788 Medical Radiology-Terminology. The first standards regarding radiation protection was established in X-ray Film Badge, which is included in the field of personal dosimeter, in 1956. Currently, 36 JIS has been established in the field of radiation management dosimeter and 3 are under arrangement. As for radiation protective supplies, 9 JIS has been established so far. Before proposal of JIS, investigation had been conducted to improve, simplify, and standardize the standards of radiation dosimetric technique, dosimeters, dosimetric procedures, and improvement. In this article, the results of material surface contamination monitoring and body surface monitoring conducted in Atomic Energy Safety Association and Radiation Dosimetry Associationare reported, and ISO and IEC are also treated.

    International System of Units abbreviated as SI units has been adopted by most of the countries of the world. Following this development, the implementation of SI units has become mandatory with a transition period of about ten years. Some of the journals have already adopted the SI units and any material sent for publication to them must use only these. International Commission on Radiation Units and Measurement (ICRU) published letters in several journals including Physics in Medicine and Biology, Health Physics, British Journal of Radiology, etc. outlining the latest recommendations on SI units to elicit the reactions of scientists in the general field of radiological sciences. Reactions to the letters were numerous as can be seen in the correspondence columns of these journals for the last few years and ranged from great misgivings and apprehension to support and appreciation. SI units have also been the subject of editorial comments in several journals. On the basis of a survey of this literature, it may be said that there was general agreement on the long term advantage of SI units inspite of some practical difficulties in their use particularly in the initial stages. This report presents a review of SI units in radiological sciences with a view to familiarize the users with the new units in terms of the old. A time table for the gradual changeover to the SI units is also outlined. (auth.)

    Training and information in the radiation protection subject is a legal mandatory as well as an essential tool for the optimisation and quality of the procedures. Accounting for the relevance of the dose to the population due to medical exposures, it seems obvious the necessity of improving this subject in order to design a feasible and efficient strategy. The importance of learning to communicate and to manage on the one hand an excessive perception of the risk to low doses in comparison with other agents, that could be made extensible for judges, lawyers and media, and on the other hand, the relevant doses due to interventional procedures, to TC studies, etc, is one of the basic commitment of a Radiation Protection Service. This paper summarises: - The contents of international recommendations, the European Directives and Spanish legislation related to this topic. - The strategy of training and information to the levels indicated, from the point of view of a referential Radiation Protection Service for a Teaching Hospital and its area associated os specialized attention and primary attention. We can not forget on-going training for owner workers. - The contents of the informative leaflets. (Author) 13 refs

    Ionizing radiation including the use of nuclear gauges can be very hazardous to humans and steps must be taken to minimize the risks so as to prevent deterministic effects and limiting chances for stochastic effects. The availability of a Radiation Protection Programme and its effective implementation ensures appropriate safety and security provisions for sealed radiation sources and promotes a safety culture within a facility that utilizes these sources. This study aims at establishing a guide on the radiation protection programme in nuclear gauges that comply with national requirements derived from current international recommendations. Elements that form part of a radiation protection programme are covered in detail as well as recommendations. The overall objective is to protect people (operators and the public) and the environment from the harmful effects of these sources if they are not properly controlled. Nuclear gauges for well logging and X-ray based gauges are outside the scope of this study. (au)

  12. The state of radiation protection in Iran

    Historically, radiation protection in Iran can be related to when the first x-ray machine was applied for medical diagnosis. However, organized activities were started with the establishment of the Tehran University Nuclear Center (TUNC) in 1959, and within a broader scope when AEOI research reactor went into operation in 1967. In 1974, the Atomic Energy Organization Law of Iran was ascribed the responsibility for radiological safety and protection to the AEOI. Then this responsibility was assigned by AEOI to the Radiation Protection Department (RPD), as the national authority. The RPD's organization and functions have been divided into three main RPD divisions: Radiation Protection Control; Radiation Dosimetry Research and Development and Services; and Radiological Protection of the Environment

  13. The revised German radiation protection ordinance

    Since August 2001, German radiation protection law is governed by a new Radiation Protection Ordinance, implementing two new Euratom Directives and taking into account new scientific developments, which provides a comprehensive basis for the protection of man and the environment. The Ordinance has been completely restructured; however, it is still a very complex piece of legislation comprising 118 provisions and 14 annexes, some of them highly technical. Reduced dose limits for occupationally exposed persons and members of the public, a detailed provision on clearance of radioactive substances, a new part aiming at the protection of man and the environment against ionising radiation emanating from natural sources, and regulations dealing with the protection of consumers in connection with the addition of radioactive substances to consumer goods are some of the centre pieces of the new legislation which shall contribute significantly to the further prevention or at least minimisation of the adverse effects of radiation exposure.

  14. From regulations towards radiation protection culture

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

    A committee of experts appointed by the Minister of Labour and Social Affairs has proposed a comprehensive draft regulation, concerning the legal aspects of occupational radiation protection in Israel. The first section of the proposed regulation sets forth guidelines for control in facilities where workers handle radioactive materials or radiation equipment. This includes the duties of the managers of such places to ensure adequate radiation protection and also the maximum recommended doses (whole body and individual organs) for radiation workers. The second section deals with the monitoring regulations for radiation workers who may be exposed to doses in excess of 500 mRem/y. The third section outlines the nature of the mechanical supervision required, i.e. routine and special examinations. Finally the committee also proposed six miscellaneous recommendations for radiation protection. (UK)

    Radiation Protection assumes special significance with increasing use of radioactive materials and processes. Scientific and industrial organisations dealing with radioactive materials have prime responsibility of ensuring effective control of all activities which may lead to radiation exposure. Training of all the persons involved in the work associated with radioactivity is absolutely necessary to develop radiation protection skill, radiation measurement proficiency and special precautions to be taken in abnormal situations. NPCIL having responsibility for design, construction, operation and de-commissioning of nuclear power plants, employs about 10,000 workers on several project/station sites all over the country. NPCIL has developed a good training system to accurately control the exposure of workers to radiation. This paper covers the system and other relevant details of radiation protection training organised by NPCIL. (author)

    The International Society of Radiographers and Radiological Technicians (ISRRT) is an international non-governmental organisation in official relationship with the World Health Organization. Over 50 countries are members of the ISRRT. The ISRRT encourages and facilitates communication between radiographers throughout the world. The ISRRT has produced several documents, e.g. ''The Role of the Radiographer in Europe''. The ISRRT has also done research and developed initiatives to analyse the quality of training of radiographers in the different member states of the EC. Research was done in the member states to analyse the efforts in the field of quality control. An extended study was performed on the current level of education in radiation protection in the European member states. The ICRP recommends in its publications the need of good training and continuing education for all radiographers. An important part of the basic training of radiographers should focus on the performance of radiation protection and quality control tests. Good daily practice can decrease patient dose in many ways.
