2010—2013年上海市宝山区放射工作人员外照射个人剂量监测分析

Individual doses of radiation workers in Baoshan District of Shanghai from 2010 to 2013

  • 摘要: 目的 了解上海市宝山区放射工作人员外照射个人剂量水平,为进一步加强和改善放射防护工作提供科学依据。 方法 依据国家和上海市放射卫生相关规定,采用热释光剂量仪器检测放射工作人员的外照射个人剂量。对异常值发生的原因进行调查及分析。 结果 2010-2013年共监测3 291人次,放射工作人员外照射人均年剂量当量为0.76 mSv/a,98.45%放射工作人员年剂量当量<5 mSv。企业放射工作人员外照射人均年剂量当量最高,为0.82 mSv/a,其次为公立医院(0.73 mSv/a),私立医院最低(0.31 mSv/a)。2010-2013年外照射个人剂量监测异常发生率逐年下降(趋势χ2=16.14,P<0.01),共有49人次监测异常,其中44人次为不规范使用个人剂量计造成的虚假剂量,确因工作原因受到过量照射的仅5人次。 结论 宝山区大部分放射工作人员外照射个人剂量处于较低水平,但仍有超标现象,应加强对企业放射工作人员的放射防护培训与监管。

     

    Abstract: Objective To understand the individual dose levels of radiation workers in Baoshan District of Shanghai,and to provide scientific evidences for developing radiation protection in the district. Methods The thermoluminescence dosimetry was used to measure the individual dose level of radiation workers according to the national and Shanghai regulations on radiological health protection. The data was analyzed to describe the variation of exposure levels. Results From 2010 to 2013,a total of 3 291 records were collected and 49 records were reported to be abnormal. The follow-up investigation showed that 44 abnormal records were due to artificial intention and 5 cases had really high exposure. The mean annual dose equivalent was 0.76 mSv/a and annual dose of 98.45% radiation workers was less than 5 mSv. The radiation worker in the enterprises had a highest mean annual dose equivalent(0.82 mSv/a),compared with that of staff in governmental hospitals (0.73 mSv/a), or staff in private hospital (0.31 mSv/a). The abnormal rates of individual dose declined year by year from 2010 to 2013 (χ2 trend=16.14,P<0.01). Conclusion Though the individual dose levels of most radiation workers in Baoshan District were low, there were still a few cases with higher levels. The supervision should be enforced.
