Uranium in several human tissues (lung, liver, kidney, muscle, spleen, heart, cerebrum and bones) from Japanese in the Tokyo area was determined by the fission track method. The average U content was the highest in lung with 1.70 ppb wet, and decreased in the order of lung greater than bones greater than heart and muscle greater than kidney greater than liver and spleen, showing markedly different tendencies from the description in the 1982 UNSCEAR Report (UNSCEAR82). Correlations were observed between U content in lung and in other tissues. These data suggest that the contribution of inhalation of U to its total intake is not negligible. The total body burden of U for the ICRP Reference Man (ICRP74) was estimated to be about 40 micrograms, which is rather small compared with the average normal burden of 90 micrograms currently accepted by the International Commission on Radiological Protection (ICRP79).
采用裂变径迹法测定了东京地区日本人几种人体组织(肺、肝、肾、肌肉、脾、心脏、大脑和骨骼)中的铀含量。铀的平均含量在肺中最高,湿重为1.70 ppb,依次降低的顺序为肺>骨骼>心脏和肌肉>肾脏>肝脏和脾脏,这与1982年联合国原子辐射效应科学委员会报告(UNSCEAR82)中的描述呈现出明显不同的趋势。观察到肺与其他组织中的铀含量之间存在相关性。这些数据表明,吸入铀对其总摄入量的贡献不可忽略。国际放射防护委员会参考人(ICRP74)的全身铀负荷估计约为40微克,与国际放射防护委员会目前接受的90微克平均正常负荷(ICRP79)相比,这一数值相当小。
