| Abstract |
It is very well known fact that Radon gas is the radioactive decay product of radium-226, an element that can be found ubiquitously in varying concentration throughout many soils and bedrocks, and decays into next elements in its own unique chain. The radon progeny is source of health concerns about radon and lung cancer risk associated with long rerm exposure to radon progeny has been emphasized in various ways. In view of the significant health risks associated with indoor radon, a couple of test cells was built to study on the subject above to find out mitigation method of indoor radon concentration in dwelling units and working spaces where people are exposed to radon. The most important conclusion is that the less porous and denser building materials are, the less entry rate of soil gas is measured in the cell. |
