1 Jahr Fukushima: Weiterhin grosse Anstrengungen bei Aufräumarbeiten

Directly after the accident in Japan’s Fukushima Dai-ichi nuclear power plant on 11 March 2011, ENSI ordered immediate measures for a review of the safety of the Swiss nuclear power plants.

In parallel, an interdisciplinary team of experts from ENSI (the “Japan Analysis Team”) reconstructed the events of the accident and subjected them to in-depth analysis.

ENSI Report on Fukushima IV: Radiological Effects

Nine months after the disaster at the Fukushima nuclear power plant, Japan is working to contain radiation exposure in the region of the accident. The challenges confronting the country in this endeavour are shown by the new ENSI report on the radiological effects of the accident on 11 March 2011. ENSI already deduced some “Lessons learned for Swiss radiation protection” at the end of October.
