Japan on Sunday said cesium that is generating significant radioactivity at a location in China prefecture had likely been released from the damaged Fukushima atomic facility, the Japan Times reported (see GSN, Oct. 21).
The six-reactor power plant was damaged by the March 11 earthquake and tsunami that left more than 20,000 people missing or dead in Japan. Radiation releases on a level not seen since the 1986 Chernobyl disaster forced the evacuation of about 80,000 residents from a 12-mile ring exclusion zone surrounding the site in Fukushima prefecture.
A Sunday inspection by Japanese Science Ministry and Kashiwa city authorities located an area to which rainwater had likely been carrying contaminants from the plant. The city had previously played down the likelihood that the radioactive material had originated from the nuclear facility (Japan Times, Oct. 24).
Fukushima prefecture on Thursday said two boys between 4 and 7 years old had received the highest levels of internal radiation contamination out of roughly 4,500 locals tested, Kyodo News reported. The contamination would amount to roughly three millisieverts of radiation over their lives and would not produce dangerous effects, officials said (Kyodo News/Mainichi Daily News, Oct. 21).
The Japanese Forestry Agency indicated that as soon as November it would begin to test pollen from cedar flowers located in the evacuation zone for cesium contamination, the Yomiuri Shimbun reported on Monday (Yomiuri Shimbun, Oct. 24).
The government's Science Ministry and Fisheries Agency are set to ramp up and broaden testing for radioactive materials in ocean water and marine produce, the Asahi Shimbun reported on Saturday (Asahi Shimbun, Oct. 22).
