You can’t see radon.
You can’t smell it or taste it.
But the radon levels in your home might be too high.

Exposure to radon in the home is responsible for an estimated 20,000 lung cancer deaths each year. In fact, The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths.

The amount of radon in the air is measured in “Pico curies per liter of air,” or pCi/L. While no level of radon gas is completely safe, the Department of Environmental Protection (DEP) has outlined that readings of 4 pCi/L or higher pose a serious threat to homeowners, and corrective action should be taken. Do you know what the radon levels are in your home, and what your number is? The graph below helps demonstrate the importance of knowing what your “radon number” is:

How Do Radon Mitigation Systems Work?
Think of it like a big vacuum. A fan, located in an attic or outside the building, is used to draw radon leaden air out from under a basement, crawl space, or on grade concrete slab.  If done properly, the area directly below the slab becomes negative in pressure as compared to the air in the living space above. This provides a path of least resistance for the radon gas to be vented from the home. In effect, this lowers the concentration of radon to the EPA’s acceptable level below 4.0 pCi/L.

	Pictured here, is a clear Lexan cover that would be installed over your sump pump pit. A clear cover is used so that you can view the sump pit at all times to make it easy to monitor. The Lexan cover prevents radon gas from entering your living space. This cover has both a one-way drain valve to prevent flooding, and an access lid to allow access to the sump pump for adjustments.
	The device that looks like a thermometer is called a “U-Tube Man-O-Meter” and is placed on a visible section of interior pipe. It measures vacuum. This assures you that the system is functioning.
	This is a typical exterior installation of a radon fan. The pipe continues up past the roof and disperses the radon gas harmlessly above the roof line. Moyer takes extra care to make sure the connectors match and will be aesthetically pleasing on the outside of your home.
	This is the exit point of the pipe. Note the special cover that is installed to protect the fan from rain, debris and small animals. Some installers overlook installing this important feature. As an EPA requirement, the termination point is located above the roof of the home so that there is 360º of open disbursement of radon leaden air.
	This is an overview of the complete exterior installation showing all outdoor components. The oversized vinyl downspout connects the fan and then to the suction pipe.
	Systems can even be installed in crawl spaces with dirt floors. Notice the 6ml thick fiberglass-reinforced “Radon Blanket” that acts as an air-tight seal. The pipe going through the “Radon Blanket” is the suction point.
	Using a core bit, the Moyer radon specialist drills a perfectly round hole through the concrete slab in your home. Through this opening an area is excavated (5 gallons or more), so that the radon pipe can be suspended to provide a larger surface area in which radon can be pulled from the soil. The inserted pipe has an air-tight seal, to assure no gas or water infiltration.

Fortunately, radon is a health hazard with a simple solution. To keep your family safe, test the radon levels in your house every two to four years. Moyer Indoor|Outdoor® believes it is important for every homeowner to “know their number.” That’s why we offer a free radon test kit to all of our customers. And if it is discovered that corrective action is needed, our certified Service Professionals™ are trained in radon gas removal and have the expertise to make your home safe. Even very high levels can be reduced to acceptable levels. But remember, you can’t see, feel, smell or taste radon gas, so the first step to take is to get your home tested.
