You cannot see, smell or taste radon. But it still may be a problem in your home. When you breathe air-containing radon, you increase your risk of getting lung cancer. In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.
Your radon test results will be reported in picoCuries per liter of air (pCi/L). The EPA and CM Home Inspections recommend you fix your home if your radon level is 4 pCi/L or higher.
As with other environmental pollutants, there is some uncertainty about the magnitude of radon health risks. However, we know more about radon risks than risks from most other cancer-causing substances. This is because estimates of radon risks are based on data from human studies on underground miners. Additional studies on more typical populations are underway. Your radon measurement will give you an idea of your risk of getting lung cancer from radon.
If an elevated level is found, fix the home. Contact a qualified radon-reduction contractor about lowering the radon level. The EPA and CM Home Inspections recommend that you fix the home when the radon level is 4 pCi/L or more.
