Do all basements have radon?
Basements aren’t the only place you can find radon. This is a common assumption since radon is most commonly found in basements. Unfortunately, it’s also very wrong. Radon gas can be found anywhere in any home, not just in the basement.
Can you reduce radon by opening windows?
As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.

What causes radon?
Radon gas forms naturally when radioactive metal (radium, thorium or uranium) breaks down in rocks, soil or groundwater. It evaporates and disappears outdoors, so levels outside are low. Indoors, however, radon gas can enter buildings through their foundations and become trapped.
Where does radon come from?
Radon is constantly being generated by the radium in rocks, soil, water and materials derived from rocks and soils, such as certain building materials. Radium is a decay product of uranium which is naturally occurring in the soils and rocks of the earth’s crust.
How accurate are radon tests?

What do you do if your radon levels are high?
If a radon test reveals high levels—anything above 4 pCi/L—ask for a walk-through with an EPA-licensed radon remediation specialist. You can find one through your state radon office. Most will provide a free remediation estimate, and, if the work is done, guarantee that radon levels will be acceptable.
Is radon used for anything?
It is chemically inert, but radioactive. Radon decays into radioactive polonium and alpha particles. This emitted radiation made radon useful in cancer therapy. Radon was used in some hospitals to treat tumours by sealing the gas in minute tubes, and implanting these into the tumour, treating the disease in situ.
What time of year are radon levels highest?
Radon levels can vary by season, with the highest levels typically occurring during the months that we heat our homes. That means that even if your home’s radon was below the EPA’s suggested action level of 4.0 picocuries per liter of air during the warmer months, it could be above that level during the winter.
