Previous nuclear incidents and accidents: Fukushima

On March 11, 2011, the Great East Japan Earthquake triggered a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Japan. The accident culminated in significant releases of radioactive contaminants into the environment beginning March 12, 2011. The emissions were of significant domestic concern in Japan and resulted in low but measurable levels of radioactive contaminants world-wide. The damaged nuclear power reactors in Japan do not pose a health risk to residents of British Columbia or the rest of Canada.
