Suction created by fan draws radon from beneath the concrete slab and safely vents radon outdoors Most common type of radon mitigation system PVC pipe, usually 3-4 inches in diameter, is installed from a hole drilled in the slab. It runs through the home, usually through closet space and exits out the roof. A [...]
Radon is measured in picoCuries per liter of air (pCi/L). While no level of radon exposure is considered safe, EPA has set an action level at 4 pCi/L. If radon test in a home shows levels at or above 4 pCi/L, the home should be fixed. The World Health Organization has set a reference level [...]
Most commonly installed system is called “sub-slab depressurization”. System is simple, effective and energy-efficient. Uses plumbing-type PVC pipe and a small fan to remove radon. In most cases levels can be reduced below 2 pCi/L. That solution most often would be “sub slab depressurization” or “active soil depressurization.” The real work horse of radon mitigation, [...]
