With our snow comes the opportunity for you to find out if your home is harboring the #2 cause of Lung Cancer! Radon Gas. Do you know the level of Radon in your home? Is it below 4 pCi/L? Of tests completed over the last 5 years that CSU Extension and San Juan Basin Health Department have been involved with, two of every three tests completed have required additional action! Throughout La Plata county, homes have tested anywhere from 1 to 98 pCi/L! January is National Radon Awareness Month.
Radon gas is a natural product of our particular soil, but can cause lung cancer if trapped in a living space. Radon is a colorless, odorless gas that results from decay in the soil. The gas moves through the ground and into your home via cracks and holes in foundation, collecting in enclosed spaces like basements or ground-floor living areas. Without radon testing and proper radon mitigation, radon exposure is extremely dangerous. Radon gas is the number-one cause of lung cancer among non-smokers and second leading cause of lung cancer overall. If levels are elevated one can vent radon gas from the home before it has a chance to build up to harmful levels inhaled by residents.
Home construction techniques of the last 20 years have led to tighter, more energy-efficient homes. These tighter homes also have the ability to hold more radon gas indoors. It’s critical to determine if you have radon in your home and take action.
The good news is that testing and mitigation are possible to accomplish without a lot of expense. Also because of energy tax credits available through 2010, some improvements that make your home more energy efficient can decrease radon levels in your home (30% tax credit).
To provide information and testing, we have scheduled several sessions for community residents to learn about radon. At these sessions we also have free test kit while they last (for information 382-641 or 247-5402 Ext 223).
Basic radon testing involves a test packet hung in the lowest living area of your home. Results are e-mailed to you within a day or two after the lab receives your test kit. You can also purchase the radon test kit for around $12 from local hardware stores. Hang the test for three days when your home is closed. Excess air circulation negatively impacts accuracy of radon test results.
The results are reported in picoCuries per liter of air (pCi/L), and if result is 4 pCi/L or above, a mitigation system is recommended. This typically involves soil suction radon mitigation system. One starts by sealing cracks in your home’s foundation, then installation of a vent pipe under the lowest level floor to vent outside. A specific fan could be installed to pull the gas from the soil beneath the house and vent it above the roof where it can’t reenter the structure. Most importantly, after the radon mitigation system is installed, get a second radon gas test done. Only by testing can you be sure the radon mitigation system was properly designed and installed. Your home should be re-tested every five years or, if one has a mitigation system; it should be re-tested every two years.
