What Is Radon (RN)?

Radon is a colorless, odorless, tasteless gas caused 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 elements 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 > Radium > Radon > Polonium > Lead > Bismuth > Polonium > Lead (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. This is why basements with no visible signs of cracks or penetrations still have radon problems. It's 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. It should be noted that (ASD) systems (active soil depressurization systems) installed by Connecticut Basement Systems Radon Inc often yield post-installation airborne radon results below 2.0 pCi/L (see airborne radon mitigation).

There are currently no defined standards for radon in water. However, the EPA has proposed a maximum contaminant level (MCL) of 300 pCi/L for municipal supplies with an alternative maximum contaminant level (AMCL) of 4,000 pCi/L for municipalities that adopt a multimedia mitigation (MMM) program. Currently, the state of Connecticut recommends that if your radon in water concentrations exceeds 5,000 pCi/L, you should consider reducing the radon concentrations to below 5,000 pCi/L.

Dynamics of Radon

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

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 begins to create suction upon the ground on which it sits. The greater the suction, the greater the influx of radon. It is not uncommon for airborne radon concentrations to fluctuate 100% or more from the cooling season to the heating season.

Waterborne radon levels fluctuate for different reasons, the biggest of which is that as water migrates through fissures and intercises in the sub-surface layers of the earth's crust, it is exposed to a wide array of soil and bedrock compositions. The longer the time frame that a sub-surface volume of water spends in contact with a radium bearing source, the greater the radon concentration that will dissolve into that volume of water. Furthermore, a well that taps into an aquifer that is fed from many different sources will have different degrees of influent water quality feeding in and mixing together, producing ever-changing contaminant concentrations.
