Abstract
238 U, 235 U and 232 Th.The molecules of radon gas diffuse out through pore spaces in soils and rocks and mix with the atmosphere. The radon gas has three isotopes, 222 Rn resulted by the decay of 238 U series, 220 Rn resulted by the decay of 232 Th series and 219 Rn a decay produced from the chain originating with U-235 Inhalation of radon gas leads to lung cancer and this occurs in the unventilated environments where the concentration of gas and its daughters increases.
