摘要:

目的 分析徐州市某三级甲等综合医院放射工作人员外照射个人剂量监测结果,为医疗机构的放射防护管理提供参考。方法 将徐州市某三级甲等综合医院放射工作人员作为研究对象,筛选符合纳入标准的放射工作人员周期性监测数据,对2019—2023年的放射人员个人剂量监测结果进行整理、统计及分析。结果 2019—2023年徐州市某三级甲等综合医院放射工作人员人均年有效剂量MP25P75)为0.08(0.06,0.13)mSv/a,2021年的人均年有效剂量低于2019、2022及2023年,差异有统计学意义(H=76.402,P<0.05)。不同职业类别的放射工作人员人均年有效剂量比较,差异有统计学意义(H=43.111,P<0.01),核医学工作人员人均年有效剂量中位数高于诊断放射学、介入放射学和放射治疗学。不同工龄间放射工作人员人均年有效剂量比较,差异无统计学意义(H=5.703,P>0.05),有8人次单周期受照剂量≥1.25 mSv,占监测人次的0.51%,75%的异常剂量产生的原因是剂量计曾被留在放射工作场所。结论 徐州市某三级甲等综合医院放射工作人员人均年有效剂量水平低于国家标准,仍需重点关注核医学科工作人员个人剂量监测,加强对其规范操作及防护意识的培训。

Abstract:

Objective To analyze the individual dose monitoring data of occupational external radiation exposure from a grade-A tertiary general hospital in Xuzhou City,and provide reference for radiation protection management in medical institutions. Methods The radiation personnel from a grade-A tertiary general hospital in Xuzhou City were selected as the research objects,and the periodic monitoring data that met the inclusion were screened. The personal dose monitoring results of radiation workers from 2019 to 2023 were sorted and statistically analyzed. Results The annual effective dose per capita MP25P75) among radiation workers in a grade-A tertiary hospital in Xuzhou City from 2019 to 2023 was 0.08(0.06,0.13)mSv/a,with the 2021 value being significantly lower than those in 2019,2022,and 2023(H=76.402,P<0.05). Among different occupational categories of radiation workers,the annual effective dose for nuclear medicine staff was higher than that for diagnostic radiology,interventional radiology,and radiation therapy personnel(H=43.111,P<0.01). No statistically significant difference was observed in the mean annual effective dose among radiation workers with different working seniorities(H=5.703,P>0.05). There were 8 cases with a single-cycle exposure dose ≥1.25 mSv,accounting for 0.51% of total monitoring cases. The primary cause of 75% abnormal doses was radiation source exposure of dosimeters in the workplace. Conclusion The average annual effective dose level of radiation workers in this grade-A tertiary hospital in Xuzhou is far lower than the national standard.It is necessary to pay attention to the personal dose monitoring of nuclear medicine workers and strengthen the training of standardized operation and protection awareness.
