Radon

What is it?

Radon is a radioactive gas that results when uranium breaks down.

Where it can be found in your home

It can be in the soil beneath and around your house; it enters your home through cracks and openings.

Why it's dangerous

Exposure to radon is the second leading cause of lung cancer after smoking, according the U.S. Environmental Protection Agency.

How to detect it and protect your family

You can test for radon yourself by buying a radon test kit or monitor for about $30 at home improvement stores.
