Radon is a naturally occurring radioactive gas that forms from the natural decay of uranium found in many soils. Colorless and odorless, radon can significantly increase a person's risk of lung cancer. Smokers who live in homes with high radon levels are especially susceptible to lung cancer. Radon can enter a home by moving up through the soil beneath a home and finding its way through cracks and holes in the foundation.
Many people may feel homes with basements are especially susceptible to radon, but radon can enter a home whether the home has a basement or not. Granite countertops may emit radon, but not always at levels that cause cancer. Countertops can be tested for radon emissions, and such testing is inexpensive and quick
