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.

New section: RP Events
- Details
A new section presenting the RP Events has been created in RP Library.
Following a request from some ISOE members wishing to share radiation protection events during training sessions, ETC has extracted a list of RP Events from various documents available on the site (Presentations during Management Board, Symposium Proceedings, ISOE Annual Reports, OpEx Reports), for the period 2000-2020.
RP Events are presented in a table providing a short description of the event and where it occurred (Country, Plant). It is possible to directly open from this page the associated reference document using the appropriate link.
In addition, a first attempt of RP Events description specifying Causes, Consequences, Corrective actions are also given in an Excel file.
