The Best Airborne Radon Mitigation in Weston, CT

Connecticut Basement Systems Radon Inc provides some of the best airborne radon mitigation in Weston, CT. How does it happen to get into your house? The flux of temperature makes radon concentration fluctuate, especially during the winter season, when the house is closed up and warm. We provide VOC remediation (Volatile Organic Compound remediation), so you and your family are safe from airborne radon's long-term effects. Due to the nature of the element, it’s difficult to detect until you start experiencing consistent health problems, which could take several years. You can rely on us to do radon testing if you suspect there may be airborne radon in your home.

What is Radon?

Radon is a colorless, odorless, tasteless gas created by the natural decay of uranium and radium. It can be found on the Periodic Table of Elements, and its atomic number is 86. Both uranium and radium are naturally occurring, and can be found in all rock and soil to varying degrees. Uranium is the "grandfather" of the radioactive decay chain to which radon is a part of.  The decay chain sequence of uranium is as follows: Uranium 238> Radium 226> Radon 222> lead 214>  bismuth 214> Polonium 214> Lead 210> Bismuth 210> Polonium 210> Lead >206 (stable). Radon is an inert gas, which means it's chemically inactive. Since it is chemically inactive, radon can move easily through all gas-permeable materials. Basements with no visible signs of cracks or penetrations still have radon problems. This is because the gas can permeate directly through concrete.

The most common way radon concentrations are expressed is in "picoCuries per liter" (pCi/L). A pCi/L is one-trillionth of a curie. A "curie" (named after famed Madame Curie) is the amount of activity given off by the decay of one gram of radium, which is the equivalent of 2.2 disintegrations per minute in a liter volume.  Radon is classified as a "Class A" carcinogen which means; positive links have been made between radon exposure and lung cancer from physical models, animal studies and most importantly, human epidemiological studies. The U.S. Surgeon General has stated that radon exposure is the second leading cause of lung cancer in the U.S.

The 4.0 pCi/L action level for radon in the air was established by the EPA because it is technologically feasible to achieve. However, the EPA's position is that there is no "safe threshold" for exposure to ionizing radiation; therefore, the lower your exposure, the better.  The World Health Organization established a 2.7 pCi/l Action Level after years of collective research.  It should be noted that active soil depressurization systems (ASD) installed by Connecticut Basement Systems Radon Inc, often yield post-installation airborne radon results below 2.0 pCi/L.

Dynamics of Airborne Radon Entry

Generally speaking, airborne and waterborne radon concentrations are in a constant state of fluctuation. The biggest reason behind airborne radon fluctuation is due to ever-changing weather patterns. Varying weather conditions create varying pressure differentials, which create varying degrees of influx of soil gas into the structure. The foremost condition recognized to create the greatest influx of airborne radon into a structure is known as the “stack effect”.

This scenario typically occurs in the heating season when the house is generally closed up the majority of the time. As indoor air is heated to a comfortable temperature, it begins to rise or move vertically through the structure. As the heated air moves vertically through the interior envelope of the structure, the structure itself creates a vacuum on the ground. The greater the vacuum, the greater the influx of radon bearing soil gas. It is not uncommon for airborne radon concentrations to fluctuate 100% or more from the cooling season to heating season.


Our company has provided airborne radon mitigation since 1987, making us the first Connecticut based company to offer this service. Normal radon levels in a house should be around 2.7 pCi/L, but we’ve dealt with homes with piqued levels of up to 900 pCi/L; our team is fully equipped and experienced in helping mitigate the radon in your home. Contact us today to learn more about our services. We’ll be glad to discuss any inquiries about radon and its effects as well.
