What increases my risk for radon poisoning?

Dr. Jeanne Morrison, PhD
Family Practitioner

Your risk of radon poisoning is increased when you breathe air from your environment that contains excessive amounts of radon. Radon usually comes from the ground, since dirt and rocks contain uranium, which releases radon gas as it decays. So your risk of radon poisoning depends on the extent to which you're around uranium-laden soil.

Radon levels are higher in regions where the soil is rich in uranium, and are also higher in buildings where radon is more likely to enter, such as buildings with cracks in their basements or foundations. Tightly sealed buildings with poor ventilation also have higher levels, as any radon that enters will tend to accumulate. Radon concentration will also typically be higher in lower levels of buildings and basements, since they are closer to soil. Your risk of radon poisoning is also affected by the amount of time you are exposed to radon; the longer you breathe elevated levels of radon, the greater will be the risk of developing radon poisoning.
