The Inter-Agency Committee on Radiation Safety (IACRS) has been operating since March 1990. The purpose of the IACRS (hereinafter the Committee) is to promote consistency of policies and co-ordination of activities with respect to areas of common interest in radiation protection and safety at the international level. This includes applying radiation protection and safety principles and criteria for the development and implementation of standards, and translating them into regulatory terms; fostering co-ordination of research and development; advancing education and training; promoting widespread information exchange; facilitating the transfer of technology and know-how and providing services in radiation protection and safety.
