目的:分析某军区2009—2010年放射工作人员个人剂量监测结果。方法:使用LiF(Mg,Cu,P)热释光剂量计(TLD)定期监测,依据国家有关法律法规和技术标准进行评价,对监测结果按照不同年份、不同工种进行统计分析。结果:2009年本区域放射工作人员个人剂量监测人数为789人,年人均剂量当量1.75 mSv;2010年本区域放射工作人员个人剂量监测人数为851人,年人均剂量当量1.49 mSv。这两年介入放射和核医学工作人员个人剂量高于其他工种。结论:该区域绝大多数放射工作人员的个人剂量水平较低,相应的放射工作环境是安全的;在放射防护实践中应加强重点工种人员的个人剂量监测与防护,同时应强化相关法规的落实和人员培训。
OBJECTIVE: To analyze the individual dose monitoring results of radiation workers in a military region from 2009 to 2010. Methods: The LiF (Mg, Cu, P) thermoluminescence dosimeter (TLD) was used for regular monitoring and evaluation in accordance with the relevant national laws, regulations and technical standards. The monitoring results were statistically analyzed according to different years and different types of work. Results: In 2009, the number of individual radiation dose monitors for radiation workers in the region was 789, with an annual average dose equivalent of 1.75 mSv. In 2010, the number of individual radiation dose monitors for radiation workers in the region was 851, with an annual average dose equivalent of 1.49 mSv. In the past two years, the personal dose of interventional radiology and nuclear medicine staff is higher than that of other types of work. Conclusion: The radiation dose for the vast majority of radiation workers in this region is low, and the corresponding radiation working environment is safe. In the practice of radiation protection, personal dose monitoring and protection should be strengthened for key workers, and at the same time, the implementation of relevant laws and regulations should be strengthened And staff training.
