Abstract:
Objective To develop a new software system that cau directly display the predicted results on an electronic map,in order to get a directly perceived understanding of the affected areas of nuclear and radiological terrorism events in city areas.Methods Three scenarios of events including spreading radioactive materials, dirty bomb attack,and explosion or arson attacks on the radiation facilities were assumed.Gaussian diffusion model was employed to predict the spread and deposition of radioactive pollutants,and both the internal and external doses were estimated for the representative person by using the corresponding dose conversion factors.Through integration of the computing system and Mapinfo geographic information system(GIS),the predicted results were visually displayed on the electronic maps of a city.Results The new software system could visually display the predicted results on the electronic map of a city, and the predicted results were consistent with those calculated by the similar software Hotspot(R)The deviation between this system and Hotspot was less than 0.2 km for predicted isoplethic curves of dose rate downwind.Conclusions The newly developed software system is of the practical value in predicting the effects of nuclear and radiological terrorism events in city areas.
