5 Things Buyers And Sellers Need To Know About Radon Testing

1. What is radon?

Radon is a radioactive gas that is colorless, odorless, tasteless, and chemically inert. There is no way to know if you have radon in your home unless you test for it.

Radon is formed by the natural radioactive decay of uranium in rock, soil, and water and can be found in all 50 states. Naturally existing, low levels of uranium occur widely in Earth’s crust. Once produced, radon moves through the ground to the air above. Some remains below the surface and dissolves in water that collects and flows under the ground’s surface.

2. Why is radon such a big concern?

Radon usually does not present a health risk outdoors because it is diluted in the open air. Radon can, however, build up to dangerous levels inside a house. Radon is the second leading cause of lung cancer in the United States, and the number one leading cause of lung cancer among radon testing louisvillenon-smokers.  It is particularly important to have a mitigation system if a person is living in or spending a lot of time in the basement.

Radon enters the home through cracks in the foundation. Also, if the air pressure of a house is lower than the surrounding soil (which is usually the case), the house will act as a vacuum, sucking radon gas inside. A new home can be built to be radon resistant. First you can install a layer of clean gravel or aggregate beneath the slab or flooring system and then lay polyethylene sheeting on top of the gravel layer. The builder can also include a gas-tight venting pipe from the gravel level through the building to the roof. Make sure that the foundation is sealed and caulked thoroughly.
