Exposure to Radon: What You Need to Know
Radon is a colorless, odorless, and tasteless gas that is formed naturally from the decay of uranium in rocks and soil. It can enter homes and other buildings through cracks in the foundation, walls, and floors, and can accumulate to dangerous levels if not properly ventilated.
Exposure to radon is a serious health risk, as it is the second leading cause of lung cancer in the United States, behind smoking. In fact, the Environmental Protection Agency (EPA) estimates that radon causes about 21,000 lung cancer deaths each year in the U.S.
How to Test for Radon
The only way to know if your home or building has elevated levels of radon is to test for it. The EPA recommends that all homes be tested for radon, regardless of where they are located or how old they are. Testing is easy and inexpensive, and can be done using either a do-it-yourself kit or by hiring a professional.
There are two types of radon testing kits: short-term and long-term. Short-term kits measure radon levels for a period of 2-7 days, while long-term kits measure levels for more than 90 days. The EPA recommends using a long-term kit, as it provides a more accurate picture of radon levels over time.
What to Do if You Have High Levels of Radon
If your home or building has high levels of radon, there are several steps you can take to reduce your exposure and lower your risk of lung cancer.
- Seal any cracks or openings in the foundation, walls, and floors to prevent radon from entering.
- Improve ventilation in your home by opening windows and using fans.
- Install a radon mitigation system, which uses a fan and vent pipe to draw radon out of the building and vent it outside.
It's important to note that radon levels can vary from day to day and season to season, so it's recommended that you test for radon at least once every two years, or more frequently if you've made any changes to your home or building that could affect radon levels.
Conclusion
Exposure to radon is a serious health risk, but it's also a preventable one. By testing for radon and taking steps to reduce your exposure, you can lower your risk of lung cancer and protect your health and the health of your loved ones.
