Radon gas is a silent threat that can seep into homes undetected, and the myths surrounding its presence have left many homeowners, property managers, and even real estate agents confused. Misconceptions about where radon can be found, especially in relation to granite countertops and basements, have persisted for years. But what’s the real story behind these claims? Let’s set the record straight.

Understanding Radon Gas and Its Sources

Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil, rock, and water. This gas can move up through the ground and into homes through cracks in floors, walls, and foundations. While it’s commonly associated with basements, radon can be found in all areas of a home, not just below ground level.

For real estate professionals and homeowners alike, understanding this is crucial. No matter the foundation type, any part of a home can be at risk for radon infiltration, making it important to test the entire property.

Debunking the Myth about Radon Testing Only for Basements

One of the most prevalent myths is that radon testing is only necessary for homes with basements. This simply isn’t true. Radon can enter homes regardless of whether they have a basement, slab, or crawl space. In fact, any part of a home that comes into contact with the ground is susceptible to radon infiltration. It's crucial to test all living areas, from the basement to the top floor, to ensure a radon-free environment.

If you’re involved in property transactions, addressing this misconception can save clients from potential risks. Testing for radon across all levels of a property adds value and confidence during the sale or purchase process.

The Risk of Radon Exposure from Granite Countertops

Another common myth is that granite countertops emit dangerous levels of radon. While it's true that some types of granite can release small amounts of radon, the levels are generally very low and not harmful. The Environmental Protection Agency (EPA) has conducted studies showing that the vast majority of granite countertops do not pose a significant health risk. However, it's still a good idea to test granite countertops, especially in homes with other radon concerns.

For realtors or property managers, addressing granite countertops concerns before they escalate can also help maintain a smooth transaction.

The Importance of Testing All Areas of the Home

Whether your home has a basement, slab foundation, or granite countertops, radon testing is essential. Testing the entire home ensures that no areas are overlooked. This is especially important in homes with granite countertops, as they can occasionally emit radon, though usually at levels that are not a major concern.

By thoroughly testing your home, including kitchens with granite countertops, you can protect your family or tenants from the risks associated with radon exposure.

Yes, granite countertops can emit radon, but typically at levels that are too low to be harmful. It's still recommended to test them, particularly if there are elevated radon levels in other areas of the home.

Is radon only a problem in basements?

No. While basements are commonly associated with radon, the gas can be present throughout the entire house, regardless of the foundation type
