from natural society: After testing rice near a crippled nuclear plant in Japan, Japanese researchers found high levels of radiation in the rice. The researchers took a sample of unharvested rice and found that it contained 500 becquerels of cesium per kilogram. The radioactive cesium came from the Fukushima Dai-ichi power plant after the earthquake on March 11. Until the rice containing 500 bacquerels of cesium per kilogram was found, they tested over 400 spots in Fukushima prefecture and found 136 bacquerels per kilogram was the highest level.
