Radon gas is a radioactive gas that can cause lung cancer. Radon levels below 4 picocuries per liter (pCi/L) are considered safe, while levels greater than 4 pCi/L are considered dangerous. Radon can enter homes through cracks in the foundation, sump pumps, and other openings.
Who is at risk?
Anyone who lives in a home with radon levels above 4 pCi/L is at risk of developing lung cancer. The risk is highest for people who smoke. Radon is the second leading cause of lung cancer in the United States, after smoking.
What causes radon gas?
Radon gas is created when uranium in the soil breaks down. Uranium is a naturally occurring element that is found in the soil in all parts of the United States. When uranium breaks down, it releases radon gas into the air.
How can I protect myself from radon gas?
There are several ways to protect yourself from radon gas, including:
- Test your home for radon gas. Radon testing kits are available at most hardware stores.
- If your home has high radon levels, fix the problem. There are a number of ways to fix radon problems, including sealing cracks in the foundation and installing a radon mitigation system.
- Avoid spending long periods of time in areas with high radon levels.
- If you smoke, quit. Smoking increases your risk of developing lung cancer from radon gas.
What are the symptoms of radon gas exposure?
Radon gas exposure can cause a number of health problems, including:
- Lung cancer
- Shortness of breath
- Coughing
- Wheezing
What should I do if I find out I have radon gas?
If you find out that your home has high radon levels, the first step is to fix the problem. Radon mitigation systems can reduce radon levels in your home to safe levels. Radon mitigation systems typically use a fan to draw radon gas from the soil and vent it outside.
