2015—2017年我国部分诊疗机构放射工作人员职业健康监测调查与分析

目的 分析2015-2017年我国部分放射诊疗机构放射工作人员的职业健康监测数据，为职业性放射性疾病的预防和控制提供科学依据。方法 通过"全国放射卫生信息平台-职业健康监测模块"采集近三年部分放射诊疗机构放射工作人员职业健康监测相关数据，并进行统计与分析。结果 2015-2017年监测医院放射工作人员个人剂量监测率分别为98.3%、98.9%、98.7%；职业健康检查率分别是95.5%、94.8%、95.7%。外周血淋巴细胞染色体畸变异常人员比例逐年降低分别为：0.9%、0.7%、0.3%；眼晶状体混浊率逐年降低分别为8.6%、7.7%、7.9%；甲状腺检查异常率逐年增加分别为18.8%、21.1%、22.1%。结论 总体上，我国放射诊疗机构放射工作人员的职业健康监护水平逐年提高，但眼晶状体和甲状腺的检查和防护仍需高度关注。

Investigation and analysis of occupational health monitoring of radiation professionals in radiology clinics from 2015 to 2017

Objective To analyze the occupational health monitoring data of radiation workers in some radiology and treatment institutions in China from 2015 to 2017, providing scientific basis for prevention and control of occupational radioactive diseases.Methods According to the "National Radiological Health Information Platform-Occupational Health Monitoring Module", data on occupational health monitoring of radiation workers in some radiological clinics in the past three years were collected for statistical analysis.Results The personal dose monitoring rates of the radiation workers in the monitoring hospitals from 2015 to 2017 were 98.3%, 98.9%, and 98.7%, respectively; the occupational health examination rates were 95.5%, 94.8% and 95.7%, respectively. The ratio of radiation workers' chromosomal aberration of peripheral blood lymphocytes was decreased by 0.9%, 0.7% and 0.3%, respectively. The opacity of the posterior capsule of the eye was decreased by 8.6%, 7.7% and 7.9%, respectively. The abnormal rates of thyroid examinations increased by 18.8%, 21.1%, 22.1% per year.Conclusion In general, the level of occupational health monitoring of radiation workers in radiology clinics in China was remarkably improved in recent years, however the inspection and protection of the lens and thyroid gland are of additional concerns.
