^(60)Co辐照场误入事故照射人的剂量调查分析

AN INVESTIGATION ON IRRADIATED DOSE FOR WORKERS ENTERED A ^(60)Co γ IRRADIATION ROOM.

本文报告^(60)Co 辐照场误入事故中,两名工作人员受到不均匀的照射。通过现场模拟实测受照人员全身等效吸收剂量。根据受照射的条件估算受照人员全身红骨髓计权平均剂量,与实测量相接近。说明^(60)Co 辐照场误入事故的剂量计算用红骨髓计权平均剂量方法可行。

An accident with ununiformly exposure resulted from two workers entered a ^(60)Co γirradiation room was re- ported in this paper.The whole-body equivalent absorbed dose was measured with imitating method at the acci- dent place.The whole-hody bone marrow(red)weighted average dose was assessed according to the accident condition.Both measured and assessed results are close.This situation showed that using assessed results instead of measured results when such accident happend was possible.
