Radon is a naturally occurring colorless, odorless, radioactive gas that can cause lung cancer and it can be in your home in Arizona!
Testing your home is easy!

Why Should a Home in Arizona be Tested for Radon?

Radon is the second-leading cause of lung cancer in the United States, after smoking. The World Health Organization, The Surgeon General of the United States, the American Medical Association, and the United States Environmental Protection Agency have labeled radon a significant health risk.
Any house can have high radon levels. Radon is a serious health risk and no home is immune to it.
No two homes, regardless of proximity, have the same radon exposure. Radon generally moves a distance of only 20 to 30 feet through the soil to a building. Consequently, the source for the radon entering a building is, generally, near or just beneath the building. Soils can vary from building to building, even within the same neighborhood. With the variability of soils and geology beneath homes, the only way to know if your home has elevated levels of radon is to test.

What is Radon?

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 in Arizona?

Arizona Radon Facts
  • Elevated levels of radon are found in both new and old buildings.
  • Radon can be found in buildings other than homes.
  • Radon 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.



How can I test my house for Radon?

You can order a radon test kit on our website; arizonaradonmitigation.com, and it will be shipped to your home. Remember that 1 test kit is enough for roughly up to 1,000 square feet. If your house is larger, you will need to order more kits.

Follow the instructions included with the test kit to sample your indoor air for radon.  If you are placing several test kits, they should be deployed at the same time.  Fill out the sampling information on the laboratory form, the report address is filled in, but the rest of the information is required for the laboratory to do the analysis.  Once the laboratory form is filled out, you send the test kit to the laboratory and they analyze the test kit(s) and send the result(s) to Arizona Radon Pros.  Once we get the results, we will call you to discuss the results.

Even if your test result is below 4 pCi/L, you may want to test again sometime in the future.  The closer your result is to 4 pCi/L, the more likely it is that you should repeat the short term test in the future.
