目的分析某制钢公司同位素测厚仪对周围环境的辐射影响。方法依据国家规定的评价标准和监测方法以及建设单位提供的相关材料,进行综合评价。结果测厚仪在正常工作状态下,对工作人员剂量满足《电离辐射防护与辐射源安全基本标准》(GB 18871-2002)中的相关要求,依据《含密封源仪表的放射卫生防护标准》(GBZ 125-2009),测厚仪产生的辐射环境对周围工作人员活动范围无限制。结论该项目监测结果符合国家有关标准规定的相关要求,对职业工作人员和公众是安全的,对周围环境影响较小。
Objective To analyze the influence of a steel company’s isotope thickness gauge on the surrounding environment. Methods Based on the evaluation criteria and monitoring methods stipulated by the state and the relevant materials provided by the construction unit, a comprehensive evaluation was carried out. Results Thickness gauge under normal working conditions, the staff dose to meet the “basic standard ionizing radiation protection and safety of radiation sources” (GB 18871-2002) in the relevant requirements, based on “with sealed source instrument Radiation Protection Standards” ( GBZ 125-2009). The radiation environment generated by the gage has no limitation on the scope of activities around the staff. Conclusion The monitoring results of the project meet the relevant requirements of relevant national standards, are safe for professional staff and the general public, and have little impact on the surrounding environment.
