| 目的 了解江苏省核医学科工作人员131I内照射的基本情况,分析影响内照射水平的相关因素。方法 使用器官计数法对江苏省开展131I治疗的核医学科工作人员开展了为期4年的甲状腺内照射体外直接测量。对结果进行了统计分析,估算待积有效剂量,分析了131I检出率与可能因素的相关性。结果 监测周期内共监测50家医院847人次,其中131I检出345人次,检出率40.7%。甲状腺内131I单次检出活度的最高值为24.83 kBq,平均值为77.3 Bq,检出人员中位数为28.3 Bq。工作人员年摄入量引起的待积有效剂量平均为0.201 mSv,检出人员中位数为0.074 mSv。结论 各年度工作人员甲状腺131I检出率分布差异有统计学意义,与检出率相关的主要因素有年龄、医院等级、工作岗位、所在地区、是否使用自动分装仪、操作方式、接触量以及接触时间。内照射情况应当引起足够重视,应当对所有此类工作人员的内照射情况进行进一步有效的监测。 |

| Objective To understand the basic situation of occupational internal exposure to 131I among nuclear medicine staff in Jiangsu province, and to analyze the relevant factors that contribute to the formation of internal exposure. Methods A four-year external direct measurement of thyroid organ counting was conducted on nuclear medicine staff who underwent 131I treatment in Jiangsu province. The result were statistically analyzed, and the effective dose of accumulated internal exposure was estimated. The relationship between the detection rate of internal exposure and 10 possible factors was analyzed. Results A total of 847 person-times were monitored during the monitoring period, of which 345 person-times were detected for 131I, with a detection rate of 40.7%. The highest individual monitoring result for internal exposure was 24.83 kBq, with an average value of 77.3 Bq and a median of 28.3 Bq among the detected individuals. The average committed effective dose of internal exposure for staff was 0.201mSv, with a median of 0.074mSv among the detected individuals. Conclusions There is statistically significant difference in the detection rate of individual doses of internal exposure among nuclear medicine staff in each year. It has been observed that the main factors related to the detection rate are age, hospital grade, job position, location, whether there is an automatic dispensing operation, operating method, exposure level and length of exposure. Sufficient attention should be given to the situation of internal exposure, and further effective monitoring should be conducted on all such staff members. |
