摘要
为了控制工作人员的内照射剂量水平，我们对北京市从事￣（１２５）Ⅰ工作的人员甲状腺中的￣（１２５）Ⅰ进行监测，并估算了工作人员所受的内照射剂量。共监测８个单位，７９人，其中７８人有明显的￣（１２５）Ⅰ内污染。所测到的甲状腺中￣（１２５）Ⅰ滞留量为０．０１－６．３２ｋＢｑ。人均待积剂量当量为０．３５ｍＳｖ。总的集体待积剂量当量为２７．７人·ｍＳｖ。
The results of ￣(125)Ⅰ monitoring in the thyroid of labelling workero in Bijing are presented. Thyroidof 79 workere engaged in routine ￣(125)Ⅰ-labelling in the severai laberatories of Bijing are monitored.Among themseventy-eight workere presents a ￣(125)Ⅰobvious contamination. The deposition of ￣(125)Ⅰ in thethyroid glands is within the range of 0. 01-6. 32 kBq. The estimated intake for workere is lower than1/10 of arunual limit of intake. Colledctive dose equivalent is 27. 72 man ·mSv. The per capita doseequivalent is 0. 35 mSv.
