Description

Radioactivity imaging and radioactivity measurement of 134Cs and 137Cs were performed for a wheat plant grown in Fukushima, after about 2 months of Fukushima Daiichi nuclear accident. The radioactivity was about 100 times higher in the withered leaves (about 300kBq/kg) than new leaves(about 3kBq/kg). The radioactivity was the lowest in panicles. The images by an imaging plate showed that the high radioactivity was found as many spots in the old leaves, suggesting that the radionuclides are strongly adhered to the leaves.
