Inhabitants of Ramsar, a city in northern Iran, are exposed to high levels of natural radiation as high as 55–200 times higher than the average global dose rate. Furthermore, radon levels in some regions of Ramsar are up to 3700 Bq/ m3. And also radon has long been known to be among the main causes of lung cancer. Here in this article we will evaluate the values of radon gas in the most polluted radioactive area of Iran and also the world. Different geological formations as the most logical reason will be used to find the comprehensive map of radon generated by Arc GIS software at mentioned area.
