Breathing radon in indoor air can cause lung cancer. Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe it. As they break down further, these particles release small bursts of energy. This can damage lung tissue and increase your chances of developing lung cancer over the course of your lifetime. People who smoke have an even greater risk. Radon in indoor air is the second leading cause of lung cancer. About 22,000 deaths a year in the U.S. are caused by breathing radon in indoor air. Radon can cause lung cancer in anybody, but people who smoke are at an increased risk. Also, your risk of developing radon-related lung cancer increases with higher levels of radon exposure.
