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.

Is there Radon in Arizona?

EPA classifies Arizona as Moderate Potential: all Arizona counties have a predicted average indoor radon level between 2 and 4 pCi/L. 

Is Radon dangerous?

Based on the American Cancer Society, elevated levels of radon over an extended period of time can cause lung cancer. 


How can I test my house for Radon?

You can order a free test kit on our website; arizonaradonmitigation.com, and it will be shipped free of charge 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.

Frequently Asked Questions

EPA classifies Arizona as Moderate Potential: all Arizona counties have a predicted average indoor radon level between 2 and 4 pCi/L. EPA also recognizes there are some hot spots though and EPA recommends that all the houses must be tested.

Radon gas comes from the soil that is in direct contact with our home’s foundation. Our home breathes in and out and as our home takes air in, in can pull radon gas into the home through cracks in floors or walls; construction joints; or gaps in foundations around pipes, wires, or conduit. Any hole can be an entrance for radon in our home.

After calling an expert company like us, we will visit your house and evaluate the best solution to mitigate the radon. The most common approaches are active soil depressurization (ASD) and mechanical ventilation (MV). According to the EPA's "A Citizen's Guide to Radon", the method to reduce radon "primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside", which is also called sub-slab depressurization, active soil depressurization, or soil suction.

As a licensed contractor, we provide a two year workmanship warranty and in most cases guarantee to get your indoor air radon levels below the EPA safe level. Once the mitigation system has been installed, an initial short term radon test should be done to verify the mitigation system is working and lowering indoor air radon levels.

If I build a new house, is there still the danger of radon? YES Newly built homes are not risk free. Many construction companies and architects are not fully aware of the radon issue. You can ask a radon certified consultant to analyze your project and suggest building techniques during construction on how to prevent radon intrusion.
