2010-2017年南通市某医院核医学工作人员个人剂量和健康检查结果分析

Investigation on individual doses and health condition of nuclear medicine workers in a hospital in Nantong City,2010-2017

目的通过分析某医院核医学科工作人员8年外照射个人剂量以及职业健康状况,为医院核医学科放射防护管理提供科学依据。方法个人剂量采用热释光剂量计LiF(Mg,Cu,P),体检资料采用省级行政部门认可的机构。结果 8年间该医院核医学科共监测放射工作人员92人次(普放科515人次)。该医院核医学科工作人员个人剂量值均高于诊断放射学工作人员(核医学科人均年有效剂量为0.43～0.94 mSv,普放科室人均年有效剂量为0.10～0.51 mSv),差异具有统计学意义,职业健康体检结果未见明显异常。结论 8年间该医院核医学科工作人员个人剂量人均值均低于管理目标值(5 mSv/年),明显高于普放科室人均剂量,放射人员健康状况良好,核医学科仍是医院需重点加强放射防护的部门。

Objective Through analyzinge the status of individual doses and health condition of nuclear medicine workers in a hospital during 8 years,to provide scientific basis for the radiological protection management of nuclear medical department.Methods LiF(Mg,Cu,P)dosimeter was used for monitoring individual dose,and the physical examination data were recognized by the provincial administrative department.Results Totally 92 nuclear medicine workers and 512 radiological diagnosis workers were monitored during the 8 years.There was statistical difference between the individual dose of nuclear medicine workers and that of radiological diagnosis workers during 8 years(the per capita annual effective dose of nuclear medicine workers was(0.43~0.94)mSv/a,and the radiological diagnosis was(0.10~0.51)mSv/a,and the results of occupational health examination showed no obvious abnormality.Conclusion For the 8 years,the average individual dose level of nuclear medicine workers was lower than the management target value(5 mSv/a),and the individual dose level was obviously higher than the radiological diagnosis workers.The radiological workers were in a good health,and the department of nuclear medicine is still need to strengthen radiological protection.
