Radon Mitigation Exhaust Vent

 

OLYMPUS DIGITAL CAMERA

Many homes in Colorado have been equipped with radon mitigation systems in the last 20 to 25 years. Radon is potentially hazardous gas emitted from soils into the interior of homes normally through basements and crawl spaces where open exposure to the soil allow the invisible, radioactive gas (a by product of the breakdown or uranium and radium) to enter. The EPA (Environmental Protection Agency) has determined that levels of radon in the air, in OLYMPUS DIGITAL CAMERAexcess of 4.0 pCi/L present a risk to the health of the occupants as it has been linked to lung cancer. Homes that contain this level or greater exposure are required to have mitigation systems installed to reduce the levels of radon to 4.0 pCi/L or less.
Systems like the one pictured above are highly effective and when installed properly and maintained. One recent development is of concern to those who have current systems in place. Pictured above is an older installation with the exhaust vent located at close to ground level. The Colorado Dept. of Public Health and Environment now requires that all radon vent pipes to the exterior be installed with the exhaust exit pipe higher than the upper level roof line. Installations like the one pictured here, will need to be updated with the vent pipe extended above the upper level of the home to prevent the exhaust gasses from re entering the building or contacting people adjacent to the home outside.
