Today is the 25th anniversary of the Chernobyl incident. On April 26, 1986, one of the reactors at the Chernobyl nuclear power facility (in what is now Ukraine) exploded. To remember, look at the photos on: http://www.boston.com/bigpicture/2011/04/chernobyl_disaster_25th_annive.html. They are very, very, moving - beautiful as well as tragic.
In the wake of the more recent Fukushima disaster, a number of countries such as Germany, China and Switzerland, have re-assessed their nuclear power plans. Other nations are considering such moves. In the meantime, the leaks at Fukushima, continue to threaten the health of the population of Japan, not just through direct exposure, but through food and water.
