Other, less often considered, naturally occurring contaminants also can affect a property. Radium is a decay product of uranium which is naturally occurring in the soils and rocks of the earth's crust. This threat is due to radon's extremely radiative nature, having . While you can't see or smell it, you can protect yourself from it. The presence of naturally occurring radionuclides in soil, rock, water, and air along with cosmic radiation results in continuous and largely unavoidable radiation exposures of all humans. New description: Contact with and (suspected) exposure to radon and other naturally occurring radiation; 2018 description: Contact with and (suspected) exposure to radon and other naturally occuring radiation; 2020 (effective 10/1/2019): No change; 2021 (effective 10/1/2020): No change; Radon is considered by the US Environmental Protection Agency, the US Surgeon General, and the American Lung Association to be the second-leading cause of lung cancer in the United States. DIFFUSION OF RADON IN SEVERAL NATURALLY OCCURRING SOIL TYPES. Outside, radon disperses rapidly and isn't a health issue. Radon itself is radioactive and it decays to form the element polonium. Soil contains radon gas, this gas can seep into homes through cracks and holes in the foundation and . In Illinois, it is State law to install a passive radon mitigation system (essentially all of the PVC pipe but not the fan unit) in all new . Radon (Rn-222) is a naturally occurring, short-lived noble gas (half-life 3.825 days) and is the sixth element in the radioactive decay chain of U-238, one of the major natural isotopes on earth.
