Worldwide Responses to the 20 Millisievert Controversy  20ミリシーベルト論争への世界的反響

December 31, 2012
Volume 10 | Issue 54 | Number 66
Article ID 4670

Between 2012 and 2014 we posted a number of articles on contemporary affairs without giving them volume and issue numbers or dates. Often the date can be determined from internal evidence in the article, but sometimes not. We have decided retrospectively to list all of them as Volume 10, Issue 54 with a date of 2012 with the understanding that all were published between 2012 and 2014.

On April 19, the Japanese government raised the allowable annual radiation exposure limit from 1 mSV (millisievert) to 20 mSV. The decision has been heavily criticized by experts inside and outside Japan, as it is applied to children who are more susceptible to radiation, and this limit does not take internal radiation dosage into consideration. 20 mSV is the yearly average of what is allowed for Japanese nuclear plant workers under normal circumstances. On this website, we have so far primarily written and provided information in English on this "20 mSV" issue and on the Fukushima nuclear crisis in general. In this post we attempt to compile a list of articles, video news, press releases available in English and other languages.
