24.14 milli-sieverts, to be exact, in 40 days. But no one bats an eye over the number any more. Japan is busy doing the “Golden Week holidays”.
There are still people remaining in Namie-machi.
Yomiuri Shinbun (5/2/2011) reports:
???????????????????????????????????????????????
On May 2, Ministry of Education and Science announced the cumulative radiation levels at 6 locations 29 to 33 kilometers from TEPCO’s Fukushima I Nuclear Power Plant.
??????????????????????????????????????????????????????????????????????????????????????
The cumulative radiation level from March 23 to May 1 in Akogi in Namie-machi, Fukushima Prefecture, 31 kilometers northwest of the plant, was 24,140 micro-sieverts, or 24.14 milli-sieverts.
Note the number is not counting the radiation from March 11 to March 22, when the release of radioactive materials from the reactors was the worst. The government DOES HAVE THE DATA that could be used to estimate the radiation levels in many places in Japan during that initial period.
