Dr. Oz Talks Radon

By | Radon | No Comments

“Just because a home does not have a basement, does not mean they do not have radon. There is a major misconception that new construction with passive pipes, homes on slabs and homes with crawl spaces do not have radon. We have actually seen all three of these home types have higher radon levels than some with full basements.”
– Amanda Yeager, Radon Project Manager.

Reducing radon requires more than just sealing cracks in the foundation of a building. Caulking and sealing alone has actually proven to not be a reliable technique.

Years of extensive hands-on radon mitigation experience, research, and long-term studies of radon mitigation systems have formed proven mitigation techniques for any types of building such as homes, schools, and commercial facilities.

An active soil depressurization system is a reliable and cost-effective technique for reducing radon.

It pulls the radon gas from beneath the building and exhausts it above the roof far enough away that it will not reenter. Operating costs of this system are minor due to the low power consumption of the fan.

A plastic pipe is connected to the soil through a hole in a slab floor, a sump lid connection, or beneath a plastic sheet in a crawl space. A fan is attached inline with the pipe and continually exhausts the radon outdoors.

An Invisible Cause of Lung Cancer

A cancer-causing radioactive gas that comes from the soil and can seep into any type of building- house, office, school, hospital, etc.…It can get in through cracks in solid floors and walls, construction joints, gaps in suspended floors and around service pipes, cavities inside walls and even in the water supply.

It is found all over the United States, but areas are broken into three zones measured in picocuries per liter of air (pCi/L).

  • Zone 1 Highest Potential (greater than 4 pCi/L)
  • Zone 2 Moderate Potential (from 2 to 4 pCi/L)
  • Zone 3 Low Potential (less than 2 pCi/L)

No level of radon is safe, but anything above 4 pCi/L needs to be mitigated. Franklin County, PA and the immediate surrounding counties are all in Zone 1 meaning those counties have the highest radon exposure risk.


However, if your next-door neighbor’s house tests at 27 pCi/L, your home could test at 36 pCi/L or it could test 2 pCi/L. Many factors play a part in radon levels. The building structure, the wind, how much uranium is in the soil, rocks or water etc…


Just because the surrounding area tests high doesn’t mean your house will test high.


But the only way to know is to test.

How Do I Know If My Home Has Radon?

Radon in Home



Radon is an odorless, colorless, tasteless, naturally occurring radioactive gas that comes from the breakdown of uranium in rocks and soil.  Uranium deposits can be found randomly throughout our environment.  Radon gas enters buildings through hollow block walls, cracks in the foundation floor or walls, and opening around drains, pipes and sump pump holes.  Therefore, the only way to determine if radon gas is entering your building is through testing.


There are two types of radon tests:

  • Short term:  These tests typically last from 48 hours to seven days.  Closed house conditions must be maintained during the test.
  • Long term:  These tests typically last from 90 days to a year and provide a long-term average of the building’s radon level.  Closed house conditions are not required for this test.

A radon mitigation system is recommended for any building whose test results show levels of 4 pCi/L (picocuries per liter) or higher.


It is estimated that 40 percent of Pennsylvania homes have radon levels greater than the EPA guideline of 4 pCi/L.  Radon is the second leading cause of lung cancer in the United States today and is estimated to cause approximately 21,000 deaths annually.
