Radon (Radon 222) is a decay product of radium. It is a gas that is radioactive, tasteless, odorless, and colorless. According to health experts, radon is the main cause of lung cancer among non-smokers and the Surgeon General of the United States, states radon exposure is the second leading cause of lung cancer in the general population -; only smoking causes more deaths. The EPA recommends the installation of a radon mitigation system if indoor radon levels exist between 2 and 4 pCi/L, as no exposure level is considered safe. However, at levels of 2 pCi/L and less, the lower levels of sensitivity for measuring devices have been reached and errors upwards of 300% have occurred.
The first step is to have a Mitigation System Pittsburgh PA installed. Air pressure within a home is lower than that on the ground below and around the foundation. As a result, the structure (home or building) acts as a vacuum sucking radon into the structure through any crack, crevice, or gap in the building’s foundation. There are a few primary types of Mitigation System Pittsburgh PA that may be considered depending on the building’s foundation type.
- Slab-on-grade or Basement -; The most commonly used Mitigation System Pittsburgh PA method is the sub-slab depressurization system. The installation involves drilling a hole four to six inches wide through the slab or basement floor. A shallow pit is hollowed beneath, and a PVC suction pipe is inserted and routed to a fan creating a vacuum. The radon gas is vented outside the home through a single pipe extending beyond the roof.
- Crawlspaces -; In homes with crawlspaces the preferred Mitigation System Pittsburgh PA method is sub-membrane depressurization. Similar to the sub-slab suction, a thick polyethylene sheet is laid on the soil. A perforated pipe may be placed in the plastic. This pipe is typically connected to solid PVC piping and fan, which creates a vacuum beneath the plastic, collecting the radon and exhausting outside.
As with any radon mitigation method, it is imperative to ensure an airtight seal by using caulk, seam tape, and making foundation repairs. These systems are cost-effective and generally consume less than 90 watts per day, per fan. A minimal expense with massive benefits. It is highly recommended that an experienced contractor that is either state or nationally certified install the radon mitigation system.
