| Abstract: | This paper focuses on the radon source in the residential dwellings,its formation mechanism and the enrichment of radon to the human body.The radon and its daughter elements are the decay products of the radioactive elements such as uranium and thorium and the important carcinogenic factor of causing the lung cancer.The radon resources in the houses of different area are quite different.The process of radon enrichment includes the radon formation,the radon immigration to the surface and into the rooms.Finally the authos put forward some measures taken for the prevention from radon hazards and the reduction of radon concentration in the house. |
