Radon Levels

Radon Levels in Fairfield, Seymour & Surrounding Areas in CT

What is a safe level of radon?

The U.S. Environmental Protection Agency established the 4.0 pCi/L action level for airborne radon, an invisible, odorless, naturally occurring radioactive gas that emanates from soil and rock. Radon concentrations are expressed in "picocuries per liter" (pCi/L). Radon is classified as a "Class A" carcinogen. Positive links have been made between radon exposure and lung cancer. Radon exposure is the second leading cause of lung cancer in the U.S.

Radon levels are measured by professionals or DIY test kits you can buy at a hardware store or online. If a radon test shows an exposure level above 4 pCi/L, the EPA recommends installing a radon mitigation system to bring the radon level below the 4 pCi/L threshold. However, there is technically no "safe" radon level. If a radon test result reveals radon in your air or water, you need to reduce your exposure.

What causes radon to be high in CT homes?

Outdoors, radon diffuses harmlessly into the atmosphere. But indoors, radon that enters a building through cracks and openings in the foundation can accumulate at a hazardous level. Radon gas can permeate through the porous concrete. This means foundations with no visible cracks or penetrations can still have radon problems. Radon levels are typically higher in homes with unsealed crawl spaces.

Every Connecticut home should be tested for radon. Because soil conditions can vary greatly even within a small geographic area, radon levels in neighboring houses don’t predict your home’s radon level. Temperatures vary widely from season to season in Connecticut. Continuous fluctuations in temperature cause radon levels to increase and decrease.

Radon levels are typically higher during the winter. During the heating season, when homes are closed up most of the time, radon concentrations can be significantly higher. Warmer indoor air rises or moves vertically through the structure. As the warmer air rises, this creates a vacuum within the building, a process known as the "stack effect." This draws radon up from the soil, through the foundation and lower levels of the home, and eventually into the upper floors or main living spaces. The good news is homes with high radon levels can be fixed with a radon mitigation system installed by a qualified Connecticut radon mitigation professional. We offer free in-home assessments and estimates for lowering radon levels.

Reduce radon levels in your CT home with a radon mitigation system

After a radon test, the first step is to determine whether or not you need to take action to reduce your radon exposure. If high radon levels are found in your home's indoor air or water, there are proven techniques for lowering radon levels to help reduce your exposure. CT Radon and Well Water Solutions is experienced in various radon mitigation solutions, and we can design the right system for your home. We typically install active soil depressurization systems, which can bring airborne radon levels below 2.0 pCi/L.
