Cesium 137 and the follies of Chernobyl and Fukushima

The Fukushima Nuclear Disaster Is Far From Over   HUFFINGTON POST, Robert Alvarez, Senior Scholar, Institute for Policy Studies, 22 April 12, “….It’s been 26 years, since the Chernobyl reactor exploded and caught fire releasing enormous amounts of radioactive debris — seriously contaminating areas over a thousand miles away. Chernobyl revealed the folly of not having an extra barrier of thick concrete and steel surrounding the reactor core that is required for modern plants, in the U.S., Japan and elsewhere. The Fukushima Dai-Ichi accident revealed the folly of operating several nuclear power plants in a high consequence earthquake zone while storing huge amounts of highly radioactive spent fuel in vulnerable pools, high above the ground.

What both accidents have in common is widespread environmental contamination from cesium-137. With a half-life of 30, years, Cs-137 gives off penetrating radiation, as it decays and can remain dangerous for hundreds of years. Once in the environment, it mimics potassium as it accumulates in the food chain. When it enters the human body, about 75 percent lodges in muscle tissue, with, perhaps, the most important muscle being the heart.http://www.huffingtonpost.com/robert-alvarez/the-fukushima-nuclear-dis_b_1444146.html
