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. ISOE provides experts in occupational radiological protection with a forum for communication and exchange of experience. A total of 71 utilities in 29 countries participate in the programme as well as the regulatory authorities of 25 countries. The ISOE databases enable the analysis of occupational exposure data from 401 operating commercial nuclear power plants (representing about 91% of the world's total operating commercial reactors), as well as 80 units undergoing decommissioning.
The Sixteenth Annual Report of the ISOE Programme summarises achievements made during 2006 and compares annual occupational exposure data. Principal developments in ISOE participating countries are also described.
