摘要: 目的 分析掌握四川省成都市某核特色三甲综合医院放射岗位医务人员接受职业性外照射的个人剂量情况,评价其防护及相关管理效果。方法 收集并整理该医院2021—2024年期间所有放射工作人员个人年度受照剂量数据,用统计分析软件(SPSS)对收集数据开展回顾性分析。结果 该院2021—2024年个人受照的年有效剂量中位值为0.34 mSv,其中2023年最高(0.38 mSv),2024年最低(0.28 mSv),差异有统计学意义(P<0.01);不同工种相比,放射牙科学样本量太少不纳入讨论,放射治疗年有效剂量中位值最低(0.24 mSv),核医学年有效剂量中位值为0.44 mSv,差异有统计学意义(P<0.01);人均年有效剂量男性与女性的差异无统计学意义(P>0.05)。结论 该院辐射防护现状总体安全,能有效保障放射工作人员的职业健康,建议按照防护最优化的原则,持续关注不同工种放射岗位医务人员的个人剂量和职业健康检查情况。

Abstract: Objective To analyze and understand the individual dose of occupational external exposure among medical radiation workers in a nuclear-specialized tertiary Grade A general hospital in Chengdu, Sichuan Province, and to evaluate the effectiveness of its protection and related management. Methods Data on the annual individual exposure doses of all radiation workers in this hospital from 2021 to 2024 were collected and organized. A retrospective analysis of the collected data was conducted using statistical analysis software (SPSS). Results The median of annual effective dose for workers in this hospital from 2021 to 2024 was 0.34 mSv. The highest dose was observed in 2023 (0.38 mSv), and the lowest in 2024 (0.28 mSv), with a statistically significant difference (P<0.01). Comparison among different job categories showed that the sample number for dental radiology was too small to be included in the discussion. Radiotherapy workers received the lowest annual effective dose (0.24 mSv), while nuclear medicine workers received a dose of 0.44 mSv, with a statistically significant difference (P<0.01). There was no statistically significant difference in the annual effective dose between male and female workers (P>0.05). Conclusions The current status of radiation protection in this hospital is generally safe and effectively safeguards the occupational health of radiation workers. It is recommended to continuously monitor the individual doses and occupational health examination results of medical workers in different radiation job categories, adhering to the principle of optimizing protection.
