The Information System on Occupational Exposure (ISOE) was created by the OECD Nuclear Energy Agency in 1992 to promote and co-ordinate international co-operative undertakings in the area of worker protection at nuclear power plants. The ISOE Programme provides experts in occupational radiation protection with a forum for communication and exchange of experience. The ISOE databases enable the analysis of occupational exposure data from the 465 commercial nuclear power plants participating in the Programme (representing some 90% of the world's total operating commercial reactors).
The Thirteenth Annual Report of the ISOE Programme summarises achievements made during 2003 and compares annual occupational exposure data. Principal developments in ISOE participating countries are also described.
