Radon and Thoron are the radioisotopes which radiate high alpha energy particles. These two gases can enter in the body by different ways such as inhalation, eating and drinking and then destroy body`s internal tissues and cause the lung cancer. The condensation of these gases differs in various areas and is more in zones near active faults. In this research, first the relation of Radon and Thoron concentration with the effect of distance of North east active faults in about 100 residential places of Iran is studied. Results show that residential places near active faults have more concentration of Radon and Thoron than other places. Also in these places the concentration of Thoron is two or three times more than Radon. The maximum amounts of Radon and Thoron concentration are 188Bq/m3 and 803Bq/m3 with the average amounts of 71.52Bq/m3 and 326/44Bq/m3 respectively.
