摘要:
目的 了解某钢铁企业放射工作人员职业性外照射个人剂量水平,完善放射防护措施,保障放射工作人员身体健康,促进企业安全发展。 方法 选取该钢铁企业各涉源单位控制区和监督区放射工作人员(5个单位87人)为监测对象,使用热释光测量仪对其外照射个人剂量水平进行监测分析。 结果 放射个人剂量平均值为0.444 mSv,年剂量范围为0.568~6.130 mSv, 87.5%的人员年均剂量<2 mSv,集体剂量为151.41人& #183; mSv。 结论 该企业放射工作人员个人剂量低于国家剂量限值标准,防护措施较好,但个人剂量管理上仍存在问题,需进一步改进。 Abstract:Objective To understand the personal dose received by radiation workers in an iron and steel enterprise, and to improve radiation protective measures, guarantee workers' health, and promote enterprise development. Methods In an iro n and steel enterprise, 87 radiation workers from control and supervision areas of 5 radiation source involved units were selected as monitoring subjects. Thermoluminescent dosimeter was used to monitor and analyze external radiation dose. Results The average personal radiation dose was 0.444 mSv. The range of annual dose was from 0.568 mSv to 6.130 mSv, and annual radiation doses in 87.5% subjects were less than 2 mSv. The collective dose was 151.41 person& #183; mSv. Conclusion The personal doses of the radiation workers selected are lower than the national limit. Though proper radiation protection measures are adopted, it is necessary to strengthen personal dose management in further.
