What is the recommended method to remediate radon in a home?

The recommended method to remediate radon in a home is by installing a venting system to the outside. This method, known as radon mitigation, is designed to effectively reduce the concentration of radon gas in indoor air. A typical radon mitigation system involves the installation of a pipe system and a fan that draws radon gas from beneath the home and discharges it outdoors, where it is dispersed into the atmosphere, reducing exposure to harmful levels of radon.

The effectiveness of this method lies in its ability to directly address the source of radon. Radon typically emanates from the ground, particularly from soil and rock, and venting it outside lowers the radon levels inside the home significantly. This proactive approach ensures ongoing safety and is often required when elevated radon levels are detected.

Alternative methods such as sealing windows and doors, running air purifiers, or using charcoal filters do not adequately reduce radon levels. Sealing might help to some extent, but it does not eliminate the problem of radon entry and can even trap radon indoors. Air purifiers generally do not have sufficient capacity to remove radon and are not a practical solution for this gas. Charcoal filters, while useful for some air quality issues, do not
