摘　　要：[目的]研制建立核和辐射卫生监测公众内照射剂量估算软件。[方法]使用POWERBUILDER 11.5,运用IAEA-TECDOC-1162出版物中有关食入和吸入途径内照射剂量估算方法,结合江苏省田湾核电站周围人群健康背景资料编制软件。[结果]建成核和辐射卫生监测公众内照射剂量估算软件,并运用软件计算2010年度田湾核电站30km半径范围内食品中137Cs致公众内照射集体有效剂量为5.05人.mSv。2011年应对日本核电站泄漏辐射监测期间,南京地区蔬菜中131I致公众内照射有效剂量最大为2.2×10-4mSv。[结论]该软件可满足核电站正常运行和事故状态下,食入和吸入两种途径公众内照射待积有效剂量的快速计算评价。为保证评价准确性,需要对核电站地区人口结构和饮食结构资料进行定期调查。[ Objective ] To establish an estimation software of internal radiation dose for nuclear and radiation health monitoring. [ Methods ] Based on the dose estimation methods for internal radiation including ingestion and inhalation in IAEA- TECDOC-1162, a rapid assessment software was developed using POWERBUILDER 11.5 combined with the health background of residents surrounding Jiangsu Tianwan Nuclear Power Plant. [ Results ] According to the software, the collective committed effective dose of 137Cs in food within a radius of 30kin around Jiangsu Tianwan Nuclear Power Plant was 5.05 man · mSv in 2010; the maximum effective dose of 131I in vegetables was 2.2 × 10-4 mSv in Nanjing during Japan＇s nuclear leakage accident in 2011. [ Conclusion ] The software could be applied to fast evaluation of public internal radiation effective dose combining both ingestion and inhalation pathways, whenever the nuclear power plant is under normal operation or emergency condition. In order to ensure the accuracy of evaluation, more regular updates of population structure and dietary information around the nuclear power plant are expected.
