is about 1.3 pCi/L indoors and 0.4 pCi/L outdoors. Meaning, any building that has a level of 4.0 pCi/L or higher should be effectively “mitigated.” Ideally, you want your radon level to be as close to zero pCi/L as possible, but in reality the average radon level in the U.S. The EPA recognizes the radon level 4.0 pCi/L as the official action level. And, your newly installed radon mitigation system is the only way to prevent new radon from entering your home. Your home naturally vents radon and existing radon naturally decays, but if your home has a high radon level, you will want to give your house enough time for the radon to clear, hence the waiting time before testing. We recommend you wait 7 to 30 days to conduct the post-installation radon test because radon (Rn222) has a half-life of 3.8 days, meaning the picocuries per liter (pCi/L) (the unit by which radon is measured) reduces by approximately half every four days. Most short-term charcoal radon test kits require a test period of 72 to 168 hours and should not be conducted sooner than 7 to 30 days after your radon mitigation system has been installed.

Since radon can be affected by diurnal cycles (24-hour cycles that follow a full rotation of the earth), changes in temperature or atmospheric pressure that occurs from day to day, radon tests normally cannot be conducted in fewer than 48 hours. How long do I have to wait to conduct my radon test? (Postage and analysis costs have been prepaid by SWAT Environmental for your convenience.) Air Chek is the top provider of radon test kits in the United States. Follow the kit instructions then simply drop the kit in the mail. The Air Chek charcoal test kit can be implemented by any adult living in the home. SWAT Environmental will provide a test kit with each installation performed. This post-installation test confirms that radon levels have been reduced to non-hazardous levels.
Testing After a System Has Been InstalledĪfter your initial radon test and following the installation of your SWAT Environmental radon mitigation system, it is critical to test. Below is a picture listing the many different ways radon can enter your home.ĭiagram of a typical radon mitigation system. Radon can enter the home through many different avenues. Radon is a naturally-occurring, odorless and colorless gas that is produced by the decay of uranium in soil, rock, and water. We currently have the largest and the most talented team of staff and technicians of radon mitigation professionals in the U.S. Our knowledgeable staff has over 80 years of combined experience in removing radon from homes, businesses, schools, townhouses, condominiums, commercial, and government buildings. We believe it is our responsibility to create healthier homes and workplaces in neighborhoods everywhere. Our business has grown since it was first established in 1988 due in part by our early participation in the EPA Radon Contractor Proficiency Program. SWAT Environmental is the nation’s largest provider of radon mitigation and remediation services.
