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.
Cumulative Percentage of Homes That Have Been Tested for Radon by Year, New Jersey (*HNJ2010/HNJ2020*)
**This is a Healthy New Jersey 2010 (HNJ2010) and Healthy New Jersey 2020 (HNJ2020) Objective.** HNJ2010 target is 30.0%.
The number of tests was determined by looking at standard (tests that were not duplicate or blank), non-post-mitigation tests
that were conducted in residential buildings in the period between January 1, 1992 and December, 31st of the calendar year
