الگوهای پراکندگی مواد پرتوزای رهاشده در اثر وقوع سوانح در نیروگاه های هسته ای اطراف ایران

Released radioactive materials from a nuclear power plant due to an accident can be transported to far regions by wind. Some models are available to predict the dispersion. This article reports some parts of the results of a research in which using one of the models, named HYSPLIT, to predict the dispersion of some isotopes of iodine and cesium released from ten nuclear power plant to the atmosphere. These power plants are located in 20-50o N & 25-75o E. The results show that a severe accident in each of the power plants potentially are able to contaminate Iran. In nuclear emergency preparedness and response plan, source of hazards should not only be limited to Bushehr Nuclear Power Plants, but also all the nuclear power plants located in the region should be considered. The results can be used to optimize site locations for early warning monitoring stations for radioactive materials.
