Radon is a colorless, odorless, radioactive gas that forms naturally in soil. Radon is produced when uranium in the soil breaks down.​

Radon is known to cause lung cancer and it can seep into our homes and workplaces through cracks and openings in floors and crawlspaces. When this happens, radon becomes part of the air we breathe.​

A home radon test is best performed by a trusted and certified Radon Professional. You’ll hear that you can perform a home test yourself, which is true, but many states (like CO) require “certified test results” from a licensed radon professional.

• A mitigation system should be installed if the concentration of radon is greater than or equal to 4.0 pCi/L. These systems should include sealing cracks and openings and installing PVC piping and a fan to remove radon gas, to prevent radon from entering your home.

• Find a National Environmental Health Association (NEHA) certified mitigation contractor in Colorado who can install a radon mitigation system.​​

When a person is exposed to radon over many years, the exposure can increase the risk of lung cancer. Radon is the second-leading cause of lung cancer in the United States – only smoking causes more lung cancer. Radon is the leading cause of lung cancer in non-smokers.

Each year, about 20,000 deaths in the United States are attributed to radon-caused lung cancer. Risk of lung cancer from radon is almost 10 times higher for smokers compared to those who have never smoked. Smoking and radon together create a greater risk of lung cancer than either one alone.​

The U.S. EPA and the U.S. Geological Survey have evaluated the radon potential in the U.S. and have developed this map is to assist National, State, and local organizations to target their resources and to assist building code officials in deciding whether radon-resistant features are applicable in new construction. This map is not intended to be used to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested regardless of geographic location. The map assigns each of the 3,141 counties in the U.S. to one of three zones based on radon potential. Each zone designation reflects the average short-term radon measurement that can be expected to be measured in a building without the implementation of radon control methods. The radon zone designation of the highest priority is Zone 1.
