Background radiation: Radiation that comes from environmental sources including the earth's crust, the atmosphere, cosmic rays, and radioisotopes . Natural sources of radiation account for the largest amount of radiation exposure received by most people each year with medical and occupational sources accounting for only a fraction of that exposure. It is currently believed that radon , a gas produced by radium decay within rock, constitutes the major source of background radiation throughout many parts of the US. The buildup of radon in inadequately ventilated homes may pose a long-term health hazard. The deleterious effects of background radiation, estimated as causing 1-6% of spontaneous genetic mutation , rise with dose.
