What is a radon mitigation system?

A radon mitigation system, also known as a radon reduction system or radon remediation system, is a specialized system designed to reduce elevated levels of radon gas in indoor spaces. These systems are installed in buildings, such as homes, schools, and workplaces, to mitigate the health risks associated with high radon concentrations.

Components of a radon mitigation system may include

Sub-Slab Depressurization (SSD) System

This is one of the most common types of radon mitigation systems. It involves installing pipes and a fan in the building's foundation to create a vacuum effect, drawing radon gas from the soil beneath the building and venting it safely outside, away from occupied areas.

Monitoring and Alarm Systems:

Some advanced systems may include monitoring devices or alarms to provide ongoing information about radon levels or to alert occupants in case of system malfunction. Air Sense is a dealer for all Air Things Monitors. Check the bottom of your invoice for discounted pricing on long term radon monitors for your home and system.

Crawl Space or Basement Ventilation

For buildings with crawl spaces or basements, moisture barriers act as a deterrent to soil gases, including radon, by reducing their movement from the ground into the crawl space and subsequently into the home. Radon can migrate as a gas through porous materials, and a properly installed moisture barrier can help limit its entry.

Sealing and Caulking

Mitigation may also involve sealing cracks, gaps, or other openings in the foundation or floors to prevent radon entry.

Radon Exhaust Fans

Fans are used to create negative pressure within the system, ensuring that radon gas is effectively pulled from the soil and expelled outside, away from the building.

Sump-Pump Mitigation

In properties with sump pumps, Air Sense will repair/replace the current lid to provide an air tight seal from the sump pit to the open atmosphere inside the home.

Radon mitigation systems are designed and installed by trained professionals specialized in radon mitigation. The type of system required often depends on the specific characteristics of the building, such as its construction, foundation type, and radon levels present. The primary goal of a radon mitigation system is to reduce indoor radon concentrations to levels deemed safe by health authorities, thereby minimizing the health risks associated with radon exposure. Regular testing and maintenance of these systems are essential to ensure their effectiveness in maintaining low radon levels within a building.
