Abstract

This study examined the accumulation and tissue distribution of radioactive cesium nuclides in Japanese Black beef heifers raised on roughage contaminated with radioactive fallout due to the accident at the Fukushima Daiichi Nuclear Power Station on March 2011. Radiocesium feeding increased both (134)Cs and (137)Cs levels in all tissues tested. The kidney had the highest level and subcutaneous adipose had the lowest of radioactive cesium in the tissues. Different radioactive cesium levels were not found among parts of the muscles. These results indicate that radiocesium accumulated highly in the kidney and homogenously in the skeletal muscles in the heifers.

摘要

本研究调查了2011年3月福岛第一核电站事故导致放射性沉降物污染的粗饲料喂养的日本黑毛小母牛体内放射性铯核素的积累及组织分布情况。放射性铯喂养使所有测试组织中的（134）Cs和（137）Cs水平均升高。在所测试的组织中，肾脏的放射性铯水平最高，皮下脂肪的放射性铯水平最低。肌肉各部位未发现不同的放射性铯水平。这些结果表明，放射性铯在小母牛的肾脏中高度积累，在骨骼肌中均匀积累。
