There is no debate. All major national and international organizations that have examined the health risks of radon agree that it causes lung cancer. In fact, it’s the second leading cause of lung cancer, preceded only by smoking. Second hand smoke ranks third.

You’re exposed to some level of Radon, no matter where you live or work, worldwide. But every home and building is different.

Your home’s Radon level could be 1 pCi/L (pico Curies per Liter), while your neighbor’s could be 10 pCI/L.

The EPA recommends that Americans fix their homes when the radon level is 4 pCi/L or more, and that you consider doing so at levels between 2 pCi/L – 4 pCi/L, especially in the area that you sleep in.  The World Health Organization recommends a level of 2.7 pCi/L or below.

Consider that exposure at a level of 4 pCi/L for eight hours per day is the equivalent of 200 chest x-rays per year! So a level as low as 2 pCi/L is like 100 chest x-rays of radiation to your lungs.
