我们总结了2011年核事故发生后3年对日本福岛县农牧业、林业和渔业生产中放射性铯浓度水平的检查情况。2011年3月至2011年6月，放射性铯浓度超过100Bq/kg的比例为农产品（不含稻米）18%，畜牧业3%，林业49%，渔业52%。 2011年6月后，放射性铯浓度急剧下降。农畜产品中放射性铯浓度几乎不超过100 Bq/kg。另一方面，林产品和水产品中的放射性铯浓度逐年下降，但也有少量高浓度样品。大豆是农产品之一，放射性铯浓度高于其他农产品。我们分析了污染地区大豆的吸收过程。地上部分放射铯浓度为侧根>叶≒叶柄≒荚果>茎≒主根。植物各部位放射性铯：钾的浓度比存在差异。比较10个大豆品种，野生大豆的放射铯浓度比其他品种高出两倍以上。大豆籽粒内的放射性铯基本均匀地分布在整个籽粒中。
We summarize the inspections of radiocesium concentration levels in agricultural, livestock, forest and fishery produced in Fukushima Prefecture, Japan, for 3 years from the nuclear accident in 2011. The ratio in which radiocesium concentration exceeded the 100 Bq/kg from March 2011 to June 2011 was 18% in agricultural products (excluding rice), 3% in livestock productions, 49% in forest productions, and 52% in fishery produced. After June 2011, radiocesium concentration reduced drastically. Radiocesium concentration in agricultural and livestock products hardly exceeded the 100 Bq/kg. On the other hand radiocesium concentrations of forest and fishery products have been falling every year, but there were a little high concentration samples. Soybean is one of the agricultural products, and the radiocesium concentration is higher than the other agricultural products. We analyzed the absorption process in soybean in contaminated areas. The radiocesium concentration of the above-ground part was lateral root> leaf≒ petiole≒ pod> stem≒ main root. There was a difference in concentration ratio of radiocesium: potassium among parts of the plant. Comparing 10 soybean varieties, radiocesium concentration of wild soya bean showed more than twice as high as other varieties. And the radiocesium inside the soybean grain was distributed generally uniformly throughout the entire grain.
