Radiological Protection Report 2011 – ENSI-AN-7872

This Annual Report of ENSI deals solely with radiological protection in nuclear facilities in Switzerland: Section A covers both exposure rates for staff and individual job rates whereas Section B deals with releases from nuclear facilities and the monitoring of radioactivity in their immediate vicinity. Compared with previous years, there was little change in either collective or  average individual doses. The average individual exposure rate for personnel in nuclear facilities of 0.6 mSv was significantly lower than both the maximum annual limit for persons exposed to  radiation during their work (20 mSv) and the annual average rate of exposure for the population in Switzerland as a whole.
