Fourth Asian Regional Conference on the Evolution of the System of Radiological Protection

The NEA Committee on Radiological Protection and Public Health (CRPPH) has actively supported the open process initiated by the International Commission on Radiological Protection (ICRP) to revise its radiological protection recommendations. Whilst the ICRP has no formal power to impose its recommendations, legislation in most countries adheres to them closely. NEA member countries in the Asia-Pacific area have played an important role in this revision process. The specific views of these members were addressed in three regional conferences on the evolution of the system of radiological protection held in Tokyo in October 2002, July 2004 and July 2006. The publication of these new ICRP recommendations and the success of the previous Tokyo conferences have led the CRPPH to organise a Fourth Asian Regional Conference to discuss the next steps after their publication and implementation.

Specifically, the objectives of this conference are to:

  • Evaluate and discuss the possible implications of the new ICRP recommendations, particularly with respect to Asian expectations and possible future application in the Asian context;
  • Identify the medium- and long-term future issues relating to radiological protection, taking into account the social and cultural background of various countries in Asia and based on the results of recent CRPPH activities (Expert Group on the CRPPH Collective Opinion, Expert Group on the Implications of ICRP Recommendations);
  • Continue an open and broad dialogue between stakeholders to reach a common level of understanding of the issues being discussed in the Asian context;
  • Contribute to the evolution of the new system of radiological protection.

ICRP Recommendations

In recent years, the ICRP has launched an open process to enhance the current set of radiological protection recommendations. The ICRP is presenting new draft proposals and recommendations to the broad radiological protection community and seeking a dialogue with all interested parties or stakeholders. The objective of this open process is to reach a new generation of ICRP recommendations that are as broadly understood and accepted as possible so they will be efficiently implemented. Through such an open process, the ICRP will publish new recommendations on the ICRP website in the near future.

The preliminary focus of the ICRP development has been on new general recommendations, which will replace ICRP Publication 60. As part of this process, the ICRP has also identified a need to clarify and update its views on the radiological protection of the environment. Both of these areas are of great interest to the NEA member countries.

NEA/ICRP dialogue

As an international committee made up of nationally nominated radiological protection authorities and technical experts, the CRPPH has for most of its history actively followed the work of the ICRP. This interest continues as the ICRP develops its new recommendations. Shortly after the ICRP began to develop its new ideas based on Roger Clarke’s article on the controllable dose concept (Journal of Radiological Protection 19 No 2, June 1999), the CRPPH also began working on this issue, focusing on how the system of radiological protection could be made more responsive to decision makers, regulators, practitioners and the public. Through a series of expert groups, topical session discussions with the ICRP Chair and broad stakeholder dialogue fora, the CRPPH has produced a series of documents highlighting relevant issues and proposing possible directions to move forward effectively. Since the release of the new ICRP suggestions in 1999, the CRPPH has published 12 reports specifically addressing development of a new system, all of which are available online.
