Welcome to the ISOE Website

The Information System on Occupational Exposure (ISOE) was created in 1992 to provide a forum for radiation protection professionals from nuclear electricity licensees and national regulatory authorities worldwide to share dose reduction information, operational experience and information to improve the optimisation of radiological protection at nuclear power plants.

ISOE is jointly sponsored by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.
