NEA/ICRP Forum on the Evolution of the System of Radiation Protection

Tokyo, Japan 5-6 July 2006


The NEA Committee on Radiological Protection and Public Health (CRPPH) has been working for some time to achieve consensus with regard to the directions that the ICRP should follow in the development of new recommendations. In this process, the Asian members of the NEA have actively participated, and are supportive of this work. The specific views of the NEA's Asian members were addressed through two Asian Regional Conferences on the Evolution of the System of Radiological Protection, held in Tokyo in October 2002 and July 2004. The success of these conferences and the development of new draft ICRP recommendations led the CRPPH to organise a third Asian Regional Conference on this subject, to provide a dedicated forum dealing with Asian views. The results of this conference will be published as an NEA proceedings and will be provided directly to the ICRP for consideration.

Specifically, the goals of this conference were to;


New 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 seeking a dialogue with all interested parties or stakeholders. The objective of this open process is to arrive at a new generation of ICRP recommendations that are as broadly understood and accepted as possible so they will be efficiently implemented. The publication of these new recommendations is foreseen in the 2007 timeframe.

The preliminary focus of the ICRP development has been on new general recommendations, which will replace 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 member countries of the NEA.

CRPPH initiatives

As an international committee made up of nationally-nominated radiological protection authority representatives and technical experts, the NEA Committee on Radiological Protection and Public Health (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, with Roger Clarke's Journal of Radiological Protection article on controllable dose (Journal of Radiological Protection 19 No 2, June 1999), the CRPPH began specific work in this area, 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 developed a series of documents discussing these issues and proposing possible directions to move forward effectively. Since the appearance of the new ICRP suggestions in 1999, the CRPPH has developed and published 12 reports specifically concerning development of a new system, all of which are available from the NEA's website.

The occasion of the release of the latest draft ICRP recommendations provides the ideal timing to hold the Third Asian Regional Conference on the Evolution of the System of Radiological Protection. With the recommendations planned to be finalised in 2006 or 2007, this Conference will provide important input to the development process. In addition, CRPPH and ICRP are planning to hold North American Regional Conference (August 2006, Washington D.C.) and the Third NEA/ICRP Forum (October 2006, Prague).

Conference organisation

This conference was organised by the NEA Committee on Radiological Protection and Public Health (CRPPH), and co-organised by the Nuclear Safety Commission (NSC), Cabinet office of Japan, and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan.


Proceedings will be published by the NEA in due course after the Conference. A short executive summary of the meeting will also be prepared by a Rapporteur, and will be presented at the Third NEA/ICRP Forum on the Evolution of the System of Radiological Protection, Prague, 24-25 October 2006.
