Analysis on application of nuclear technology and radiation workers’ occupational health management in non-medical institutions in Huai’an City

Abstract

Objective To investigate and analyze the current situation of nuclear technology utilization and radiation workers’ occupational health management in non-medical institutions in Huai’an City, and to strengthen the prevention and control of occupational radiation diseases. Methods 37 non-medical institutions of nuclear technology utilization in Huai’an City were surveyed by questionnaire, including radioisotope and radiation apparatus, personal dose monitoring of radiation workers, implementation of occupational health examination, protective equipment, etc. Results The industry covers manufacturing industry, transportation, warehousing and postal industry, scientific research and technical service industry, residential service, repair and other service industries, 0 class I radiation device, 15 class II radiation devices, 67 class III radiation devices; 0 class I and II radiation sources, 1 class III radiation device, 16 class IV radiation sources, 51 class V radiation sources, 1 unsealed radioactive material Class B workplace; 493 radiation workers, 90.5% with certificates, 85.4% with personal dose monitoring rate, rate of 37.8% with radiation protection monitoring equipment, and 68.0% with occupational health examination rate. It has 13 institutions equipped with personal protective equipment, 23 with dose alarming devices and 14 with radiation protection monitors. 30 radiation workplace tests have been carried out in the past two years. Conclusion The occupational health management of radiation workers in non-medical institutions is weak. At present, the responsibility of occupational health supervision has been assigned to the health department. Therefore, the health administrative department should strengthen the supervision of non-medical nuclear technology utilization institutions and improve the emergency mechanism of radiation emergencies in Huai’an city. 摘要：目的 调查分析淮安市非医疗单位核技术利用及放射工作人员职业健康管理现状, 加强职业性放射性疾病的 预防与控制。 方法 编制调查问卷方式对淮安市37家核技术利用非医疗机构进行普查, 包括射线装置和放射源、放 射工作人员个人剂量监测、职业健康检查开展情况、防护设备配备等内容。 结果 行业覆盖制造业、交通运输、仓储和 邮政业, 科学研宄和技术服务业, 居民服务、修理和其他服务业；I类射线装置0台、II类15台、III类67台；I类、II类 放射源0枚, III类1枚, IV类16枚, V类51枚;非密封放射性物质乙级工作场所数1个。放射工作人员493人, 持证 占比90.5%, 个人剂量监测率85.4%, 辐射防护监测仪配备率37.8%, 职业健康检查率68.0%;配备个人防护用品 13家, 配备剂量报警仪23家, 配备辐射防护监测仪14家;近2年内开展过放射工作场所检测30家。 结论 非医疗机 构对放射工作人员职业健康管理薄弱, 目前职业健康监管职责己划归卫生部门, 卫生行政部门应加强对非医疗核技术 利用机构的监管, 健全我市放射突发事件的应急机制。
