Abstract:
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 IAEATECDOC-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 30 km around Jiangsu Tianwan Nuclear Power Plant was 5.05 man& #183;mSv in 2010; the maximum effective dose of 131I in vegetables was 2.2& #215;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.
