Granite countertops: radon risk?

Date Published: 01/08/2009 [Source]

Some types of granite that are used for countertops can emit radon. However, it will vary depending on where the stone is from and what elements it is composed of. Most radon risk, however, derives from gas that is emitted from the soil and that can collect in your house. Every house should be tested for radon in air, regardless of countertop material.
