#Fukushima I Nuke Plant: Radiation Exceeding 100 Milli-Sievert, TEPCO Says

Every day I wake up and hope to find good news on the nuclear plant situation. Every day it get worse.

Asahi Shinbun (in Japanese, emphasis added; 2:30AM JST 3/19/2011):

The radiation level that the workers are exposed to at Fukushima I Nuclear Power Plant has started to exceed 100 MILLI-SIEVERT, TEPCO disclosed in the early morning [past midnight] press conference on March 19.

As of morning of March 18, there are 279 workers from TEPCO and TEPCO affiliates at the plant. They are fitted with a radiation monitor on them, which sounds alarm when the radiation level exceeds 80 milli-sievert so that they stop their work. However, the radiation level has started to approach 100 milli-sievert, and in some cases exceed 100 milli sievert.

Japan's Ministry of Health, Labor and Welfare and Ministry of Economy, Trade and Industry (METI) raised the upper limit of the radiation exposure for the workers at Fukushima I Nuclear Plant from 100 milli-sievert to 250 milli-sievert on March 15.

100 milli-sievert (or 100,000 micro-sievert) is the level which one would start to experience negative effect on one's health.

The radiation that you are naturally exposed to in daily life is around 2.4 milli-sievert PER YEAR.
