On January 1st 2009, HSK became ENSI, the Swiss Federal Nuclear Safety Inspectorate and at the same time the new body became independent of the Swiss Federal Office of Energy. However, the remit of the new regulatory body remains unchanged.
ENSI continues to monitor ionising radiation and radioactivity in Swiss nuclear facilities and their immediate vicinity. It prepares forecasts on the potential course of any nuclear incident, including the spread of radioactivity into the environment. It also judges whether measures adopted by operators of nuclear facilities are appropriate.
This is the sixth annual summary report on the radiological protection issues regulated by ENSI.
