What is a Radon Mitigation System (RMS)?
An Radon Mitigation System (RMS) is a system that ventilates air containing radon, and radon daughter particles safely to the exterior of your home where they are diluted in the atmosphere. There are two main types of radon systems passive and active. A “passive RMS” is installed during new construction, and is generally the most inexpensive route. It is a layer of Polyethylene sheeting is placed on top of the gravel layer in the foundation and slab of the structure. A gas tight venting pipe ventilates sub-slab gases out the roof thru a natural drafting affect. Generally a passive system can be installed for $350- $500, and will be completely affective in eliminating radon. Occasionally these systems do not produce enough draft to control the radon level, but the installation of a electric fan can increase the efficiency of the system ridding the house of radon. The addition of a fan turns a passive system in to the second type of system, an “active radon mitigation system”. In an acti
