Why Is This Important?

Radon is a radioactive gas that comes from the breakdown of naturally occurring uranium in soil and rock. Radon can only be detected by specialized tests and can enter homes through openings that are in contact with the ground. Radon exposure is the second leading cause of lung cancer and the leading cause of lung cancer in non-smokers. The risk of cancer decreases as the radon concentration decreases so it is recommended by the Department of Environmental Protection that every home be tested and mitigated when radon levels are 4 pCi/L or more.

Definition

Cumulative percentage of New Jersey homes that have ever been tested for radon.
