Health Physics Society Recommends Considering Action For Indoor Radon Below Current Guidelines
Radon is a colorless and odorless radioactive gas that is produced by the radioactive decay of radium. Radium is a product of uranium decay and is found in trace amounts naturally in nearly all rocks, soils, and groundwater as well as building materials, plants, animals, and the human body. Radon concentration is expressed as the amount of radiation that would be emitted by radon and its decay products in a liter of air; thus the units are picocuries per liter (pCi/L).
