Radon (Rn)*

Sources: Earth and rock beneath home; well water; building materials.

Health Effects: No immediate symptoms. Estimated to contribute to between 7,000 and 30,000 lung cancer deaths each year. Smokers are at higher risk of developing radon-induced lung cancer.

Levels in Homes: Based on a national residential radon survey, the average indoor radon level is 1.3 picocuries per liter (pCi/L). The average outdoor level is about 0.4 pCi/L.

Steps to Reduce Exposure:

• Have Paragon Home Services test your home for radon, it's easy and inexpensive.
  
  
• Fix your home if your radon level is 4 picocuries per liter (pCi/L) or higher.
  
  
• Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced and should be tested again in the next 6 months to a year.
