Radon is formed naturally from the radioactive decay of uranium in rocks and soil.

It raises the risk of lung cancer – especially if you also smoke, says Ashley Sumrall, MD, FACP, a US-based oncologist.

If you live in an area where the amount of uranium and radium in rocks is high, you can be exposed to radon through cracks in your foundation.

You can also be exposed to radon if you have granite countertops.

What can you do?

If you live in an area with high levels of uranium and radium, or if you have granite countertops, consider having your home’s radon levels measured.
