Japan : Radiation levels in parts of Fukushima over limit

Via NHK News :

" The Japanese government says the radiation accumulated over a 25-day period at some locations in Fukushima Prefecture has exceeded the permissible level set for a full year.

The government announced the findings on Monday. The calculation is based on data collected from 53 locations, up to 60 kilometers from the Fukushima Daiichi power plant, from the day following the March 11th disasters through April 5th.

34 millisieverts of radiation had accumulated over that period at one location in Namie Town, about 24 kilometers northwest of the plant. This equates to about 314 millisieverts per year, more than 3 times the permissible level of 100 millisieverts.

On Monday, the government expanded its 20-kilometer evacuation zone to include towns where annual exposure is expected to top 20 millisieverts. It asked residents to evacuate within about a month."
