When the natural radioactivity found in building materials decays, it releases the radioactive gas radon. This release of radon may contribute to elevated radon levels in homes and buildings. NettetNatural radioactive elements are present in very low concentrations in Earth's crust, and are brought to the surface through human activities such as oil and gas exploration or mining, and through natural processes like leakage of radon gas to the atmosphere or through dissolution in ground water.
