Radon is a naturally occurring chemical element. Like oxygen or hydrogen, it is a gas under normal conditions; however, it is a product of radioactive decay and is very dense. This high density will cause it to settle into low areas like basements and crawl spaces. Prolonged exposure to high concentrations of radon is the second leading cause of lung cancer behind smoking. This makes it critical for homeowners to understand the air quality in their home.
Air Sealing & Insulation Specialists, Inc. is a certified radon inspector under the National Radon Proficiency Program (NRPP). Our testing involves placing a continuous radon monitor in the lowest lived in space in the dwelling and collecting a 48 hour sample window. Once the data collection is complete, a detailed report will be generated showing the radon concentrations during the monitoring period. Any radon level of 4 pCi/L (picoCuries per Liter) or greater is a concern and is the recommended level for mitigation. The recommended frequency of testing for radon levels is every 2 years.
Remediation or mitigation of radon is achieved by installing a sub-slab depressurization system. This involves coring a 3 or 4-inch hole in the basement floor and installing a vent pipe to the exterior of the home all the way to the roof line, along with a continuously running fan in the line. The system operates by drawing air from under the basement slab to the outside. This changes the direction of air infiltrating the basement so that radon in the ground is vented out the pipe rather than seeping up into the basement. This helps to prevent the radon from ever entering the home. Any cracks or openings in the basement slab are also sealed, like sump pits that can be closed with a removable cover and gasket.
A post-installation radon test will be conducted to ensure that the mitigation procedures are effectively reducing radon levels below the tolerated concentration.
