What are Wood Decay Fungi?
Where does radon come from? Radon comes from the natural breakdown (radioactive decay) of uranium. Radon can be found in high concentrations in soils and rocks containing uranium, granite, shale, phosphate, and pitch-blende. Radon may also be found in soils contaminated with certain types of industrial wastes, such as the byproducts from uranium or phospate mining. In outdoor air, radon is diluted to such low concentrations that it is usually nothing to worry about. Once inside an enclosed space like a home, however, radon can accumulate. Indoor levels depend both on a building’s construction and the concentration of radon in the underlying soil. How can radon hurt my lungs? Radon itself naturally breaks down into decay products that adhere to dust and other particles in the air, as well as the lining of the lungs. As we breathe, these particles become trapped in the lungs, releasing small bursts of energy that damage lung tissue and begin the uncontrolled reproduction of cells known a
