A radon mitigation system reduces the concentrations of radon gas in a building. Radon is a naturally occurring gas that can cause health issues in high enough concentrations. It also contributes to environmental radioactivity. A radon mitigation system is an effective way to reduce radon levels in your home. If you’d like to know how a radon mitigation system works, read on to learn about the process.
Benefits of Lifetime Radon Testing
There are two main types of radon mitigation systems. Active soil depressurization is the most common and is applicable to most buildings. This type of system reduces the pressures in the soil or rock beneath a building’s floor, allowing the air to flow out of the structure. The less common approach to radon mitigation involves reducing air pressures in the cavity of exterior or demising walls. Concrete blocks collect radon, which is why active mitigation systems are typically the best choice for homes.
The passive system is similar to an active one, but it does not require regular monitoring. Radon testing is recommended before and after mitigation systems are installed, or after repairs. Depending on the state you live in, you may need to re-test your home every ten years. The US standards for reducing airborne radon are as follows: a 2.0 pCi/L level is recommended, but some states will allow less than this.
