摘要
于2011~2016年对四川省内某大型^(60)Co-γ辐照装置进行了辐射环境水平监测,监测项目包括γ辐射空气吸收剂量率;贮源井水中^(60)Co放射性活度浓度、总β放射性活度浓度、电导率、氯离子浓度和pH值;土壤中^(60)Co放射性活度浓度;个人热释光辐射剂量。监测结果表明:所有样品的监测结果均符合相关国家标准要求;大型^(60)Co-γ辐照装置正常运行期间,不会对环境、工作人员和公众造成放射性影响。
A large-scale 60 Co-γ irradiation device in Sichuan Province was monitored for radiation environment from 2011 to 2016. Monitoring items include γ radiation dose rate,60Co radioactivity concentrations, total β radioactivity concentrations, conductivity, chloride ion concentration and pH in reservoir well water, 60 Co radioactivity concentra tions in soil and thermoluminescence dosimetry for personal. The results showed that the test results for all samples are in line with the relevant national standards. Thus, large 60Co-γirradiator facilitieswill not cause radioactive effects on the environment, staff and the public during normal operation.
