The Guide to Protecting Yourself and Your Family From Radon
EPA Recommends
- Test your home for radon — it's easy and inexpensive.
- Fix your home if your radon level is 4 picocuries per liter, or pCi/L, or higher.
- Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced.
Radon is estimated to cause thousands of lung cancer deaths in the U.S. each year.
