What is Radon Gas?

Where Does Radon Come From and Why Does It Matter?

Radon is the radioactive gas that forms when uranium goes through the natural process of breaking down over time1. This dangerous gas becomes harmful radioactive particles that interfere with our lungs and trachea when inhaled. This exposure is the second leading cause of lung cancer and has been linked to over 20,000 deaths annually2. Every home has some level of radon.

Radon has become such a relevant health risk that government agencies are now beginning to enact new guidelines regarding radon. The United State’s EPA (Environmental Protection Agency) and The National Collaborating Centre for Environmental Health in Canada have determined safe levels of radon within a structure or home should be below 4.0 pCi/l in the US3 and 200 Bq/m3 in Canada4. Action is typically required to reduce radon exposure higher than these recommendations.

Determining Radon Levels

Since radon is undetectable to our senses; it is invisible, odorless and tasteless, it’s important to use specific testing to determine the level of this noxious gas. To complicate matters more, radon gas is directly related to weather, ventilation, and characteristics of a structure’s foundation.

Because of the health risks, anomalies in location and sources, it is recommended that homes, schools, elder care facilities, daycare, and offices be tested for radon.

When To Test For Radon

It is important to measure the radon gas level in indoor air in any structure where people may spend an extended period of time especially if no radon test has ever been performed. Most states also recommend or require a home going through a real estate transaction be tested to mitigate risk of all parties. If you have detected a high level of radon and have taken measures to mitigate the gas, a follow up radon level check is highly recommended to make sure the system is working properly. The EPA also recommends testing every 2 years regardless of your test results prior5. Finally, it’s very important to test for radon after a major renovation or construction project is performed.

Reliant Radon Solutions is dedicated to the testing and mitigation of radon gas in the greater Denver area. Our licensed and experienced technicians will work to not only provide you with accurate radon gas levels in your home, daycare, or business, but are also equipped to install mitigation systems for keeping your loved ones safe by drawing out this dangerous gas away from the structure, ensuring your indoor breathing air quality is safer. If you have questions about our services or recommendations for testing in the Denver area, please contact us today.

Determining Next Steps After Radon Testing

Because both the US and Canada have determined levels of harmful concentration for radon gas, it’s important to take action after testing if levels are above the recommended amounts of 4.0 pCi/L (picocuries per liter of air) for US and 200 Bq/m3 (becquerels per meter cubed) for Canada. The concentration levels are determined by dividing the amount of radon gas by the amount of days the detector was monitoring.

When radon gas levels are high, a mitigation system is recommended, and in some states required, to push the radon gas out and away from the base of the structure so indoor air quality is safer. Most mitigation systems have several components such as sealing crawl spaces, around gaps, cracks, and the perimeter of the structure, and using a fan and piping system to distribute the gas outdoors where it is then diluted.

Many states and provinces have their own rules and licensing regarding the installation of mitigation systems. For those that do not, it is recommended in the U.S. that consumers use contractor who abide by the AARST/ANSI published standards and also use NRPP (National Radon Proficiency Program)6, NRSB (National Radon Safety Board for the US) or C-NRPP (Canadain National Radon Proficiency Program for Canada)7 certified installer. National certification programs ensure that technicians have been updated on the latest products, recommendations, and equipment relevant to the safe mitigation of radon gas.

To ensure the safety of indoor air quality, it is important to test for this radioactive, dangerous gas. Radon is a naturally occuring result of radium and uranium decay in our soil. Radon gas can cause lung cancer2. Radon is only detectable through testing because it is invisible, tasteless, and odorless.
