What is Radon Gas?

Radon is a naturally occurring colorless, odorless, radioactive gas. It forms from the decay (break down) of the radioactive element, uranium, which is found in soil and rock, right here in Arizona. As uranium in our soil decays and generates radon gas, it moves through the soil and enter our homes through cracks and openings in the foundation into the air we breathe.

The amount of radon in the soil depends on soil chemistry, which varies from one house to the next. Radon levels in the soil range from a few hundred to several thousands of pCi/L (picocuries per liter) in air. The amount of radon that escapes from the soil to enter the house depends on the weather, soil porosity, soil moisture, and the suction within the house. Testing is the only way to know your level of exposure. Radon can have a big impact on indoor air quality.

Is there Radon Gas in Arizona?

Arizona Radon Gas Facts
  • Elevated levels of radon gas are found in both new and old buildings.
  • Radon gas can be found in buildings other than homes.
  • Radon gas can be found in homes built on all types of foundations, including crawlspaces and slab-on-grade basements.
  • The percentage of Arizona homes that contain radon above recommended levels is similar to U.S. average.
  • The average radon level found in homes in the U.S. is about 1.4 pCi/L. In Arizona, the median of radon levels found in 4000+ homes during the state indoor radon survey (1987-89) was about 1.6 pCi/L.
  • Radon can vary from house to house. The only way to know the level of radon in the house you are buying or selling is to have it tested.
  • Sub-floor ductwork can increase the radon levels in your home.
  • Air furnaces and air conditioners can draw radon-laden soil gas into a home.
  • Radon levels in Arizona can often be higher in the summer air conditioning months than during months with milder temperatures.
  • Arizona Radon Pros have mitigated homes/apartments in Flagstaff, Prescott, Payson, Superior, Cave Creek, Carefree, Scottsdale, Paradise Valley, Tempe, Mesa, Chandler, Queen Creek, San Tan Valley, Phoenix, Glendale, Peoria, Litchfield Park, Goodyear, Tucson, and several other towns around Arizona and the Phoenix metropolitan area.

 

Why Radon Gas is dangerous?

Based on the American Cancer Society, elevated levels of radon over an extended period of time can cause lung cancer. When we breathe radon in the air and it decays (breaks down), tiny radioactive elements impact the lining of the lungs, where the radiation does damage to the lung tissue. These damaged lung cells can eventually lead to lung cancer.

The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO) has indicated there is sufficient evidence that radon and its progeny can cause lung cancer, and classifies them as “carcinogenic to humans.”

The conclusion that radon is a serious health risk is supported by the Surgeon General of the United States, the U.S. Environmental Protection Agency, the American Lung Association, the National Academy of Science, and the National Council on Radiation Protection.

Not everyone exposed to radon develops lung cancer; but as the level of radon and length of exposure increase, so do the health risks.

The EPA-recommended action level is not a safety standard.  Levels below 4.0 pCi/L still represent some risk. Even outdoor air contains some radon.
