2008-2011年金华市放射工作人员个人剂量监测结果分析

Monitoring Data Analysis on Personal Dosage Received by Radiation Workers in Jinhua, 2008-2011

  • 摘要: 目的 了解金华市放射工作人员外照射个人剂量水平。

    方法 采用热释光剂量测量方法,对金华市2008-2011年放射工作人员的外照射个人剂量水平进行监测。

    结果 4年中共监测799人,总集体有效剂量为854.70 man mSv,人均年有效剂量为1.07 mSv/a,年剂量< 5 mSv者占监测总人数的98.12%。在不同工种放射工作人员中,人均年有效剂量最大的为介入放射工作人员(1.97 mSv/a),介入放射工作人员监测人数逐年递增。

    结论 金华市大多数放射工作人员个人剂量水平符合国家标准的规定,介入放射工作人员是放射防护的重点对象。

     

    Abstract: Objective To assess the personal dosage level of external exposure for radiation workers in Jinhua.

    Methods Thermoluminescence dosimetry was applied to measure the personal external radiation dosage of workers exposed to radiation in Jinhua during 2008-2011.

    Results Totally 799 radiation workers were monitored from 2008 to 2011. The collective annual dosage equivalent was 854.70 man mSv and the average annual effective dosage was 1.07 mSv/a. The workers receiving annual dosage equivalent less than 5 mSv accounted for 98.12%. The average annual individual effective dosage was higher in the interventional radiology workers than in other work types, and the numbers of interventional radiology workers monitored increased every year.

    Conclusion Most of the radiation workers in Jinhua city are safe in the working conditions according to the related national standards. The interventional radiology workers should be a key population for radiation prevention.
