2009-2013年沈阳某医院放射工作人员个人剂量监测结果分析

Individual Doses of Radiation Workers in a Hospital in Shenyang, 2009-2013

  • 摘要: 目的 了解某医院放射工作人员个人剂量监测结果,探讨其变化趋势及该院放射防护措施效果。

    方法 采用热释光个人剂量计常规监测方法,通过对该院2009-2013 年129 名放射工作人员的个人剂量进行整理、分析,比较不同工种、岗位放射工作人员所受电离辐射水平差异。

    结果 2009-2013 年5 年间该院放射工作人员的人均年有效剂量为0.58~1.03 mSv/a,年均有效剂量中位数为0.71 mSv/a,其中介入治疗工作人员的年均有效剂量最高,为0.75 mSv/a。各工种放射工作人员的剂量水平普遍低于国家标准规定的年均有效剂量限值。护师年均有效剂量为0.77 mSv/a,明显高于医师的年均有效剂量。

    结论 该院放射工作人员的年均有效剂量处于国家标准规定限值的较低水平,其中介入治疗应作为放射防护的重点。

     

    Abstract: Objective To monitor the individual radiation doses of radiation workers in a hospital, and to explore its variation trend and the effect of protective measures.

    Methods Thermoluminescence dosimetry method was adopted to record the individual doses received by 129 radiation workers in a selected hospital from 2009 to 2013. The data was analyzed to compare the differences in ionizing radiation among all the radiation workers of different job titles and workstations.

    Results The mean annual personal effective doses ranged from 0.58 mSv/a to 1.03 mSv/a during the selected 5 years, and the median was 0.71 mSv/a. The highest mean annual effective dose was found in the interventional therapy technicians (0.75 mSv/a). All the mean annual effective doses estimated in this study were lower than the relevant limits of national standards. The mean annual personal effective dose of the nursing staff was 0.77 mSv/a, significantly higher than that of the doctors.

    Conclusion The mean annual effective doses of radiation workers in the hospital are below the standard limit stipulated by the national authority, and the interventional treatment should be a key to radiation protection.
