Health workers exposed to ionizing radiation account for + 50% of workers exposed to man-made radiation in France. Over the last decade, the use of radiation in medicine has increased due to the introduction of new practices. The EXposition des Professionnels de santE aux RayonnemenTs ioniSants study aims to evaluate and characterize the trends in radiation exposure of health workers in France between 2009 and 2019.
This retrospective study includes all health workers with at least one dosimetric record in the system for occupational dosimetry registration (Système d'information de la surveillance de l'exposition aux rayonnements ionisants) database for each of the years 2009, 2014, and 2019, in the hospitals included in the study. Individual external doses and socio-professional data were collected. Statistical analyses include descriptions, graphs, and logistic regressions.
A total of 1457 workers were included (mean age: 39.8 years, 59% women). The average exposure significantly decreased between 2009 and 2019 (-0.008 mSv/year, p < 0.05). There were large discrepancies in trends according to professions, departments, hospitals, and gender. Over the 10-year study period, radiologic technologists and physicians were the most exposed (0.15 mSv (95%CI 0.14-0.16) and 0.13 mSv (0.06-0.21), respectively), but their exposure tended to decrease. Workers in nuclear medicine departments had the highest radiation exposure (0.36 mSv (0.33-0.39)), which remained stable over time. Thirty-eight percent of recorded doses were nonzero in 2009, decreasing to 20% in 2019.
This study allowed to identify physicians and radiologic technologists in nuclear medicine departments as the most exposed medical workers in France, and to show an overall decrease trend in radiation exposure. This should be instructive for radiation monitoring and safety of exposed medical workers.
• Radiation exposure of healthcare workers in most medical departments has steadily decreased between 2009 and 2019 in several French hospitals. • The number of zero doses consistently increased during the study period. • Workers in nuclear medicine departments are the most exposed, especially radiologic technologists and physicians.
在法国，接触人工辐射的工作人员中，有 50%以上是放射工作人员。在过去十年中，由于新实践的引入，医学中辐射的使用有所增加。EXposition des Professionnels de santE aux RayonnemenTs ioniSants 研究旨在评估和描述 2009 年至 2019 年期间法国放射工作人员辐射暴露的趋势。
这是一项回顾性研究，纳入了每个年份（2009 年、2014 年和 2019 年）在研究医院内系统职业剂量登记（Système d'information de la surveillance de l'exposition aux rayonnements ionisants）数据库中至少有一个剂量记录的所有卫生工作者。收集了个体外照射剂量和社会职业数据。统计分析包括描述性分析、图表和逻辑回归分析。
共纳入 1457 名工作人员（平均年龄：39.8 岁，59%为女性）。2009 年至 2019 年间，平均照射量显著下降（每年减少 0.008 毫希沃特，p < 0.05）。根据职业、科室、医院和性别，趋势存在很大差异。在 10 年的研究期间，放射技师和医生的暴露量最大（0.15 毫希沃特（95%置信区间：0.14-0.16）和 0.13 毫希沃特（0.06-0.21）），但暴露量呈下降趋势。核医学科工作人员的辐射暴露量最高（0.36 毫希沃特（0.33-0.39）），且多年来一直保持稳定。2009 年记录的剂量中有 38%为非零剂量，2019 年降至 20%。
本研究确定了核医学科的医生和放射技师为法国受辐射影响最大的医务人员，并显示出辐射暴露的总体下降趋势。这对于放射监测和受辐射医务人员的安全具有指导意义。
在法国的几家医院中，2009 年至 2019 年期间，大多数医疗科室的医疗保健工作者的辐射暴露量稳步下降。
在研究期间，零剂量的数量持续增加。
核医学科工作人员的暴露量最大，尤其是放射技师和医生。
