摘要
目的为掌握甘肃省乡镇卫生院放射工作人员职业健康状况,探索放射工作人员的接触剂量的剂量-效应关系。方法选择2015至2017年某省乡镇卫生院390名放射工作人员及乡镇卫生院所在县(区)的县(区)级医院从事普放工作的放射工作人员495名,划分为研究组和对照组,以其工作量、放射防护情况及职业健康监护资料进行影响评价和风险分析。结果乡镇卫生院放射工作人员年工作量为845.33±361.62人次,县(区)级医院放射工作人员年工作量为1 967.74±762.06人次。两组间有明显差异(P<0.05);乡镇卫生院眼晶状体混浊检出率、PLT、RBC、HGB异常检出率、淋巴细胞微核率、染色体畸变率等指标差异均有统计学意义(P<0.05)。 结论乡镇卫生院放射工作人员存在一定的辐射损伤。
ObjectiveTo investigate occupational health status about radiation workers from township hospitals in Gansu, China, and to explore the dose-effect relationship of exposure dose of radiation workers.MethodsA total of 390 X-ray workers from township hospitals in Gansu Province and 450 X-ray workers from the county/district-level hospitals in the county/district where the township hospitals were located were divided into research group and control group. Their workload, radiation protection condition, and occupational health monitoring data were used for impact assessment and risk estimation.ResultsThe annual workload of radiation workers from township hospitals was 845.33±361.622 people, and that of radiation workers from county/district-level hospitals was 1967.74±762.055 people;there was a significant difference in annual workload between the two groups of subjects (P<0.05) . Indices such as detection rate of lens opacity, detection rate of abnormal platelet count, red blood cell count, and hemoglobin count, micronucleated lymphocyte rate, and chromosome aberration rate were significantly different between the two groups (P<0.05) .ConclusionRadiation workers from township hospitals suffer from certain radiation damage.
