Should I Get a Radon Test in Chicago?

What is Radon?

Radon is a radioactive gas that is produced naturally from the decay of uranium in soil, rock, and water. It is colorless, odorless, and tasteless, which means that it cannot be detected by human senses, making it all the more dangerous.


Why is it Dangerous?

Radon Risk in the US

Radon gas is a known carcinogen and is the second leading cause of lung cancer after smoking. According to the EPA, it is estimated that radon exposure causes more than 21,000 deaths from lung cancer each year in the United States alone.

Radon is measured in units of picocuries per liter (pCi/L) of air. Radon is naturally found in outdoor air at very low levels and some radon will always be in your indoor air. According to EPA, the average radon level in American homes is about 1.3 pCi/L. Exposure to just 4.0 pCi/L is equivalent to the risk of getting cancer by smoking 8 cigarettes a day for a nonsmoker.


How Does Radon Enter the Home?

How Radon Enters a Home

Radon is present everywhere. When we are outdoors, it is at very low levels. However, inside of a home the concentration builds. Radon can enter homes and buildings through cracks in foundations, walls, and floors, as well as through gaps around pipes and cables, sump pumps, and other openings.


Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.






Why is Radon Testing Important?

Testing for radon is the only way to know if it is present in a home or building. If radon is found to be present, steps can be taken to reduce the levels and minimize the risk of lung cancer. Therefore, radon testing is important for the safety and well-being of those who live there, and it is recommended that all homes and buildings be tested for radon.
