摘　　要：开展辐射监测是保障核技术利用装置安全稳定可靠运行的重要手段。本研究对湖南辐照中心^(60)Co辐照装置近5 a运行期间的工作场所、个人职业照射和贮源水井的辐射水平状况开展了监测与分析。结果表明:各场所及人员接受的辐射水平远低于国家的规定限值,贮源水井各项指标符合要求,未出现放射性活度超标的情况。引入用灰色GM(1,1)预测模型以5 a历史辐射监测数据为基础开展预测分析,结果显示,未来3 a的辐射水平变化较为稳定,且远低于规定限值,不会对周边环境与人员身体造成辐射危害。Radiation monitoring is crucial to ensure safe,stable,and reliable operation of nuclear technology utilization equipment.The radiation levels at workplaces,in water storage wells,and due to individuals'occupational exposure during the operation of ^(60)Co irradiation equipment over the past five years at the Hunan irradiation center have been monitored and analyzed.The results reveal that the radiation levels received by personnel and at various sites are remarkably lower than the national limits.All the source water quality indexes meet the requirements,and the radioactivity does not exceed the standard limits.The grey GM(1,1)prediction model was introduced to perform the prediction analysis based on 5 years of historical radiation monitoring data.The results show negligible change in the radiation level over the next 3 years,and it is considerably below the prescribed limit;hence,no radiation harm to the surrounding environment and human health would be observed.
