Radon is found throughout the entire United States. A heavier than air gas, radon is most commonly found in basement areas, however, ground level living areas are not free of radon exposure concerns. Radon typically enters a building through sumps and cracks in the basement walls and floors. Keeping a building foundation well sealed will help prevent entrance of radon gas, however, elevated levels of radon are found in many newer homes. Radon has been demonstrated to cause lung cancer in adults as well as young children.
Radon enters the body through the respiratory system, and particles embed in the lungs.
As the radon continues to decay, radioactive particles are released into the body. Radon tests are typically conducted by placing two or more charcoal canisters in the subject building for a period of approximately three days. The canister is then sent to a laboratory for analysis. Other more costly methods involve use of air monitoring equipment for a period of days to months. The Formaldehyde propellant can cause respiratory distress or severe allergies in many people.
