Exposure of Fukushima residents to radiation

Fukushima residents exposed to up to 23 millisieverts of radiation Mainichi Daily News, 22 Feb 12, FUKUSHIMA (Kyodo) — The Fukushima Prefecture government said Monday that the residents of three municipalities located near the crippled Fukushima Daiichi nuclear power plant are estimated to have been exposed to up to 23 millisieverts of radiation in the four months after the accident triggered by the March 11 earthquake and tsunami.

“As annual radiation exposure of up to 100 millisieverts poses no specific cancer risks, the estimated radiation is unlikely to cause any adverse health effects,” Fukushima Medical University Vice President Shunichi Yamashita told a press conference. “It is important to reduce future radiation exposure as much as possible.”

While the allowable radiation exposure limit is ordinarily set at 1 millisievert per year, the International Commission on Radiological Protection has recommended an emergency limit of 20 to 100 millisieverts…….   “The high-level radioactive contamination indicates that humans should not be allowed to live near the car park,” said Kobe University Professor Tomoya Yamauchi, who conducted a radiation test on the soil.

The crisis at the Fukushima Daiichi plant has resulted in heavy concentrations of radioactive substances at various locations in Minamisoma. The civic group said its discovery indicates that a fact-finding survey is urgently required throughout the city. http://mdn.mainichi.jp/mdnnews/news/20120220p2g00m0dm146000c.html
