It is the daughter product of radium- 226 which belongs to the uranium-238 decay chain. Thoron. (radon-220) Less important sources of radium are in ground water and building materials. The presence of uranium in soil and rock is an important indicator of places where 20 Oct 2020 Radon (222Rn) is a natural radioactive noble gas that occurs in the uranium decay series and is formed directly from the alpha decay of radium ( primary sources of indoor radon-222 are radon-222 gas emanations from soil and rock, However, in most cases, the major source of indoor radon-222 is.

To schedule a radon mitigation test and eradicate this gas from your home, trust a local National Radon Defense dealer for proven service. Radon is odourless, colorless and tasteless, thereby making it difficult to detect its presence in water with the human senses. 222 Rn decays to 218 Po by emitting alpha particles which are a potential health hazard if radon is inhaled or ingested (National Research Council 1999). Radon (Rn-222) is an odorless and colorless natural radioactive gas. It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils.
