The evolution of the system of radiological protection is of great interest to governments and regulatory authorities, in particular in Asia. In this context, the Japanese government hosted a series of NEA conferences on this subject. The 4th Asian Regional Conference, held in Tokyo in December 2007, included key discussions of Japanese, Korean, Chinese and Russian views on the new International Commission on Radiological Protection (ICRP) recommendations, and on their interpretation in the international Basic Safety Standards and national regulations. This report summarises the most significant aspects of these discussions, providing keen insight into governmental and regulatory approaches to radiological protection in Asia.
