Radiological protection science addresses the radiobiological and epidemiological studies of the harmful effects of ionising radiation, as well as radiological exposure and dosimetry, and social sciences. This informs the development of radiological protection policy.
The system of radiological protection continuously evolves to integrate the last findings from research and the feedback from experience, to eventually address modern radiological protection of the public, patients, workers and environment.
The Committee on Radiological Protection and Public Health (CRPPH) when draft documents of interest to the CRPPH become available for comment, typically draft ICRP recommendations, and draft updates of the IAEA Basic Safety Standards (BSS).
Additionally, the CRPPH is regularly organising workshops on radiological protection fundamentals and key issues dealing with the evolution of the radiological protection system (such as optimisation, reasonableness, stakeholder involvement).
A key radiological protection research area addresses the need to improve our understanding of radiological health risks that might be caused by exposure to low radiation doses, i.e. for doses below to far below ca. 100 millisieverts (mSv). The CRPPH has created a dedicated group to establish international networking to facilitate research co-ordination in the area of low dose research (HLG-LDR).
The CRPPH assists NEA member countries in the implementation and enhancement of the system of radiological protection. It contributes to the adoption and the maintenance of high standards of protection for the public, workers and the environment in all activities involving the use of ionising radiations, and particularly, but not limited to the field of nuclear energy.
In 2002, the NEA CRPPH established a dedicated expert group (EGIR) to evaluate draft general recommendations developed by the International Commission on Radiological Protection (ICRP) and to provide feedback on policy and implementation to the authors of the document, in order to ensure that the final recommendations reflect the views and concerns of the CRPPH.
The overall objective of the High-level Group on Low Dose Research (HLG-LDR) is to support radiological protection policy, regulation and implementation choices by improving the effectiveness and efficiency of research through global networking for the co-ordination of ongoing and future low-dose research projects. The HLG-LDR facilitates the communication of research project objectives and results to stakeholders and encourages the collective sharing of information and resources.
