Exposure to radon can increase your chances of getting lung cancer.
Scientists are more certain about radon risks than risks from most other cancer-causing substances.
Smoking combined with radon exposure is an especially dangerous health risk. These particles release bursts of energy that can damage lung tissue and lead to lung cancer. Uranium is present in most of the soil and rock around the world. It is typically concentrated in areas with lots of granite, shale, phosphate and pitchblende. Some building materials such as natural stone or rock can contain and emit radon.
