Fukushima residents exposed to up to 37 millisieverts of radiation - 9th Dec 2011

Residents in three municipalities near the crisis-hit Fukushima Daiichi nuclear power plant have been exposed to up to some 37 millisieverts of radiation during the four months after the powerful earthquake and tsunami on March 11 crippled the plant, Fukushima prefectural government officials said Friday.

The local government worked out the estimated dose of exposure after conducting health checks on about 1,730 of the 29,000 residents in the towns of Namie and Kawamata and the village of Iitate in Fukushima Prefecture, who filed their behavioral records during the four months. The average dose is estimated at just above 1 millisievert.

It calculated the radiation dose for residents, based on levels in the air measured by the Ministry of Education, Culture, Sports, Science and Technology and by the ministry's radiation projection system, called the system for predicting environmental emergency dose information, or SPEEDI, which is operated by the Tokyo-based Nuclear Safety Technology Center.
