How Does a Radon Mitigation System Work

The first thing is to find out if there is a Radon issue in the house. Once a Radon issue has been confirmed in the home, it needs to be mitigated. Mitigation of Radon is a very specific process where the Radon gas below the slab of the home is removed to the outside. This is accomplished through a series of venting and air movement from the inside to the outside.

Frequently Asked Questions

Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can cause lung cancer. According to EPA studies radon is the leading cause of lung cancer among non smokers.

The soil. Radon is produced from the natural decay of uranium that is found in nearly all soils. Uranium breaks down to radium. As radium disintegrates it turns into radon. As a gas, radon moves up through the soil and into the air you breathe.

While radon is present everywhere, and there is no known safe level, your greatest exposure is where it can concentrate indoors. And where you spend most time at home. Your home can have radon whether it be old or new and with or without a basement.

The goal of a radon mitigation system is to reduce the indoor radon levels to below the EPA action level of 4 pCi/L. A quality radon reduction (mitigation) system is often able to reduce the annual average radon level to below 2 pCi/L.

Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies. Radon is an important contributor to environmental radioactivity.

Mitigation of radon in the air is accomplished through ventilation, either collected below a concrete floor slab or a membrane on the ground, or by increasing the air changes per hour in the building. Treatment systems using aeration or activated charcoal are available to remove radon from domestic water supplies.
