What is Radon?

Radon is a naturally occurring radioactive gas that is produced by the breakdown of uranium in
soil, rock, and water.  Uranium breaks down to radium, which then decays to radon gas.  Radon
is a colorless, odorless, and tasteless radioactive gas.

How does radon enter the home?

Radon gases enter the home due to air pressure differences between the inside of your home
and the soil around your home’s foundation.  The air pressure inside the home is typically lower
than the pressure in the soil outside your home.  This difference in pressure causes your home
to act like a vacuum and draw the radon in through any openings and foundation cracks.  Radon
can also penetrate through pores in the concrete.

Is Radon dangerous?

Radon is the second leading cause of lung cancer worldwide and is the LEADING cause of lung
cancer worldwide among non-smokers.  

Radon and Children:

Children are more sensitive to radon because their lungs are smaller and their respiratory rates
are twice as high.  Doctors say that, by the age of 10, a child receives twice the lung dose of an
adult who’s been exposed to the same level of radon for the same length of time.

Radon and Smoking:

Smoking is the leading cause of lung cancer.  If you smoke and your home has high levels of
radon, your lung cancer risk is EXTREMELY high.


The Surgeon General of The Unites States and The Environmental Protection Agency (EPA)
recommends testing for radon and reducing radon in homes that have high levels.
They recommend to fix your home if your radon level is confirmed to be 4 pCi/L or higher.  
Levels less than 4 pCi/L still pose a risk, and can also be reduced.

The World Health Organization (WHO) has set the recommended action level at
2.7 pCi/L.
