Radon is a silent killer. It's a colorless, odorless radioactive gas which naturally occurs in the ground below us, and gets pulled into our homes, schools and businesses. Why should you worry about something you can't see or smell? Radon is the second-leading cause of lung cancer in the United States, with the US Surgeon General and the EPA estimating 20,000 Americans die every year due to radon exposure. Lifetime Radon Solutions is proud to be a locally owned and operated business that has been in operation since 1993! With years of experience and unmatched expertise we can help with any and all of your Radon testing and abatement needs. Get in touch today!

Radon Detection and Reduction questions, answered by experts

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.
