ABSTRACT

In this report, the Commission provides guidance for the protection of people living in long-term contaminated areas resulting from either a nuclear accident or a radiation emergency. The report considers the effects of such events on the affected population. This includes the pathways of human exposure, the types of exposed populations, and the characteristics of exposures. Although the focus is on radiation protection considerations, the report also recognises the complexity of post-accident situations, which cannot be managed without addressing all the affected domains of daily life, i.e. environmental, health, economic, social, psychological, cultural, ethical, political, etc. The report explains how the 2007 Recommendations apply to this type of existing exposure situation, including consideration of the justification and optimisation of protection strategies, and the introduction and application of a reference level to drive the optimisation process. The report also considers practical aspects of the implementation of protection strategies, both by authorities and the affected population. It emphasises the effectiveness of directly involving the affected population and local professionals in the management of the situation, and the responsibility of authorities at both national and local levels to create the conditions and provide the means favouring the involvement and empowerment of the population. The role of radiation monitoring, health surveillance, and the management of contaminated foodstuffs and other commodities is described in this perspective. The Annex summarises past experience of longterm contaminated areas resulting from radiation emergencies and nuclear accidents, including radiological criteria followed in carrying out remediation measures.

ABSTRACT

Within its occupational radiation protection programme, the International Atomic Energy Agency (IAEA) initiated and funded an international intercomparison exercise of personal dosemeters to determine the quantity personal dose equivalent in mixed neutron-photon radiation. The objectives of the intercomparison are to assess the capabilities of the dosimetry services in measuring the quantity Hp(10) in mixed neutron-gamma fields; to assist IAEA member states in achieving sufficiently accurate dosimetry; and, if necessary, to provide guidelines for improvements (not simply a test of the performance of the existing dosimetry service). The intercomparison is directed to passive dosemeters to determine, in mixed neutron-gamma radiation fields, either these two components separately or the total personal dose equivalent. The intercomparison consists of two phases: Phase I--Type-test intercomparison: irradiation in selected calibration fields and results used to improve dosimetric procedures of participating laboratories, where needed. Phase II--Simulated workplace field intercomparison: irradiation in radiation fields similar to those in workplaces as a final check of performance. The exercise revealed clear deficiencies in the methodology used by several laboratories and necessitated a detailed analysis of the existing discrepancies. This papers summaries the finding and conclusions for radiation fields similar to those found in nuclear industry.

ABSTRACT

The International Atomic Energy Agency (IAEA) conducts safety activities to support the assessment of occupational exposure due to intakes of radionuclides; a comprehensive set of safety documents will soon be completed. In recent years, extensive improvements in measurement techniques, phantoms and computational tools have been made. Thus, it is important for laboratories involved in internal dosimetry to undergo performance testing procedures to demonstrate the correctness of the methods applied and also to determine the consistency of their results with those obtained by other laboratories. Several intercomparisons were organised, and they revealed significant differences among laboratories in their approaches, methods and assumptions, and consequently in their results. This paper presents the current and future IAEA activities in support of assessment of occupational exposure due to intakes of radionuclides in the IAEA Member States, as well as the lessons learned from several intercomparison exercises in the last 5 years.

ABSTRACT

The International Basic Safety Standards for Protection Against Ionizing Radiation and for the Safety of Radiation Sources (BSS) require, inter alia, the establishment and implementation of quality assurance programmes to ensure that protection and safety requirements are met. The findings and conclusions of the International Conference on Topical Issues in Nuclear and Radiation Safety held in Vienna in 1998 includes, among others, the following recommendation concerning occupational radiation protection: The BSS require a quality assurance (QA) programme to be established as part of radiological protection. Extensive guidance for the development of a QA system is given in reports of ISO and IEC, but further guidance is needed on the interpretation and implementation of these standards. This paper is focused on the available international standards on quality assurance and on the work the IAEA is currently carrying out for their implementation in radiation monitoring services.

ABSTRACT

The objective of the IAEA Occupational Protection Programme is to promote and assist in establishing an internationally harmonised approach for optimising occupational radiation protection. Guidance for IAEA Member States is provided through the hierarchical Safety Standards Series: Safety Fundamentals, Safety Requirements and Safety Guides. A set of three Safety Guides on occupational radiation protection has been published, jointly sponsored by the IAEA and the International Labour Office. Complementary advice, either topic specific or practice specific, is published as Safety Reports in other IAEA publications. In view of the technical difficulties associated with the introduction of the new radiation quantities for measurements and reporting, the IAEA assists its Member States by offering annual dosimetry intercomparisons. The purpose of this paper is to present the current and future IAEA activities in support of occupational radiation protection in the IAEA Member States.
