Radon is an invisible, odorless, radioactive gas. It comes from the natural breakdown of uranium in soil, rock, and water. Radon gas is found all over the world, and in every state in the U.S. Levels can vary widely, even from home to home in the same neighborhood. Radon gas becomes a health hazard when it accumulates indoors and is breathed in.
According to the Surgeon General, Radon exposure is the second leading cause of lung cancer in the United States.
Air pressure inside your home is usually lower than pressure in the soil around your home's foundation. When radon gas is present in the soil, your house acts like a vacuum and draws radon in through cracks and other openings.
Testing is the only way to know if you and your family are at risk from exposure to radon. The New York State Department of Health, U.S. Environmental Protection Agency, and the Surgeon General recommend testing all homes for radon.
To test your home for radon, we will deploy one or more Charcoal Canister Testers. The small charcoal canisters contain activated charcoal which absorbs radon or its products. Each canister is barcoded for proper laboratory identification. The canisters will remain in your home for 2-5 days and then will be sealed and sent to a lab for analysis. In the lab, the radioactive particles emitted from the charcoal are counted by a sodium iodide counter. The results are then available by email within a few days.
Radon levels in the average home are about 1.25 picocuries/liter of air (pCi/L). If a radon test discloses levels of 4 pCi/L or greater, then some action should be taken to reduce the radon level.
