Radon is a naturally occurring radioactive gas that is formed when uranium decays in the soil. Uranium is in geological formations throughout North Carolina. It seeps into homes through cracks in the foundation, walls and joints. In some parts of the country, ground water can be a major source of radon. Every home in North Carolina is prone to having a level of radon gas and the N.C. Radon Program recommends that all homes be tested.
RADON GAS TESTING
Exposure to radon gas has been found to cause lung cancer. Among non-smokers, radon is the leading cause of lung cancer in the United States. Lung cancer due to radon exposure claims about 21,000 U.S. lives annually, based on EPA estimates.
​
Radon is not regulated in North Carolina. Radon is, however, found as an item on the Residential Disclosure Form. This form is used when a residential unit is being sold in North Carolina. Should the seller know the radon level of the residence, that data is considered a material fact and should be communicated to the buyer.
​
When testing for Radon Kits are placed in the house and must sit a minimum of 48 hours. Once test are picked up they will be sent to the lab. Results are normally in within 2-3 business days from being sent to the lab. The USEPA states that for test results in this range (less than 4 pCi/L) you do not need to conduct radon mitigation at this time. However, if you make any structural changes or start to use a lower level of the building more frequently you should test again
