在去污过程中，去污工人可能面临着通过吸入暴露于内照射的高风险;然而，以前很少有关于去污过程中内污染水平的研究。作者回顾了受损的福岛第一核电站附近村庄的去污工人的医疗记录，包括全身计数器测量，以评估他们的内部辐射暴露水平。总共有83名净化工作人员参加了这项研究。他们经常在表面137 Cs沉积密度超过100 kBq m−2的高度污染地区从事去污活动。目前的研究表明，福岛第一核电站附近的去污工人的内照射水平较低。所有去污工人的铯含量都低于检测限。他们没有报告任何严重的健康问题。放射性物质的再悬浮可能在去污活动中造成最低限度的内部污染。
AbstractDecontamination workers may face a high risk of exposure to internal irradiation through inhalation during decontamination activities; there is, however, little previous research on the levels of internal contamination during decontamination procedures. The authors reviewed the medical records, including whole body counter measurements, of decontamination workers in villages near the crippled Fukushima Daiichi Nuclear Power Plant to assess their levels of internal radiation exposure. In total, 83 decontamination workers were enrolled in this study. They were regularly engaged in decontamination activities in highly contaminated areas where surface 137Cs deposition density was over 100 kBq m−2. The present study showed low levels of internal exposure among the decontamination workers near the Fukushima Daiichi nuclear plant. The cesium burdens of all the decontamination workers were below detection limits. They had reported no acute health problems. The resuspension of radioactive materials may cause minimal internal contamination during decontamination activities.
