Radon Survey

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water.

Air pressure inside your home is usually lower than pressure in the soil around your home’s foundation. Because of this difference in pressure, your house acts like a vacuum, drawing radon in through foundation cracks and other openings. Radon may also be present in well water and can be released into the air in your home when water is used for showering and other household uses. In most cases, radon entering the home through water is a small risk compared with radon entering your home from the soil. In a small number of homes, the building materials (e.g., granite and certain concrete products) can give off radon, although building materials rarely cause radon problems by themselves. In the United States, radon gas in soils is the principal source of elevated radon levels in homes.

Radon is a Cancer-causing, radioactive gas. It is estimated to cause many thousands of lung cancer deaths each year. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Grant Associates performs short-term tests for the presence of radon gas in your home. This is done by placing one or more non-toxic canisters in your home. The round metal canister is filled with 25 grams of activated charcoal held in place by a fine mesh screen. The canister is left in place between 48-96 hours. The canister is then retrieved and delivered to a laboratory for analysis.

Upon receipt of the analytical results, Grant Associates provides the client with a detailed report describing the findings of the assessment and providing appropriate recommendations.

Although Grant Associates does not perform remediation of radon accumulation, we can direct clients to several reputable firms in the area who do.
