High radiation levels of more than 250,000 becquerels per kilogram of radioactive cesium have been detected in male flowers of Japanese cedar trees in the restricted zone around the damaged Fukushima Daiichi nuclear power plant.
The Ministry of Agriculture, Forestry and Fisheries collected male Japanese cedar flowers from 87 locations throughout Fukushima Prefecture between late November and early December to measure radioactive cesium levels.
A ministry spokesperson said 253,000 becquerels of cesium per kilogram were detected in the flowers collected from Namie, 11.3 kilometers from the stricken plant, TBS reported. The ministry also said that levels exceeded 10,000 becquerels per kilogram at 29 different locations.
Meanwhile, the Ministry of the Environment said that during the pollen season, the peak level of pollen grains in the air has been measured at 2,297 per cubic meter.
The ministry claimed that if nearby residents were to inhale this concentration of pollen for four months, they would be exposed to 0.553 microsieverts of radiation. However, the ministry added that this does not constitute a great health risk, as it amounts to roughly 10 times the background radiation level in Tokyo's Shinjuku Ward, TBS reported.© Japan Today
