在福岛县采集的土壤岩心样本中测定了福岛第一核电站排放的碘-131和铯-137的垂直剖面。剖面显示，超过76%的放射性核素保留在距表面5厘米的范围内。浸出实验表明，铯与土壤颗粒结合强烈，2 M HCl不能浸出，而40%以上的碘被掺入腐殖质中。
Vertical profiles of iodine-131 and cesium-137 emitted from the Fukushima Daiichi Nuclear Power Station were determined in soil core samples collected in Fukushima prefecture. The profiles showed that more than 76% of the radionuclides were retained within 5 cm of the surface. Leaching experiments showed that cesium was strongly bound to soil particles which could not be leached with 2 M HCl, while more than 40% of iodine was incorporated into humic substances.
