日本福岛第一核电厂注水作业工作人员的剂量计算

Radiation Dose Calculation of Fireman Carried out Affusion in Fukushima Daiichi Nuclear Power Plant

根据日本政府核事故应急指挥部公布的数据,对参与日本福岛第一核电厂乏燃料水池注水作业工作人员分别受圆柱形、链形、锥形、扇形、漫烟形、屋脊形6种典型烟羽模型照射的吸收剂量率进行了计算。结果表明:身着含铅防护服工作人员受圆柱形和漫烟形烟羽照射的吸收剂量率分别为最小值0.14×102μGy/h和最大值5.35×102μGy/h;在同种放射性烟羽模型照射下,工作人员身着含铅防护服时吸收剂量率值小于未着气衣时值。计算结果将为核事故应急受照工作人员的剂量评估和医学治疗提供参考。

According to the data released by the nuclear emergency response headquarters of Japan, the absorbed dose rate irradiation plume with the spent fuel pool water injection operations staff in the fukushima - daichi nuclear power plant was calculated, who have been irradiated by six typical cloud models, including , chain, taper, fan - shaped, pervading and roof cloud model respectively. Results show that absorbed dose rate of Japan Self - Defense Forces who irradiated by and pervading cloud model is 0.14×10^2μGy/h （minimum） and 5.35×10^2μGy/h （maximum）. Irradiated by the same cloud model, the absorbed dose rate of fireman who dressed in protection suit is smaller than those who dressed in ordinary cloth. The calculated results will provide a reference for evaluation of radiated dose and therapeutic treatment of irradiated worker in nuclear emergency accident.
