The New Jersey Department of Health has published its “Radon Screening by Homes by Years 2004-2024,” available at https://www-doh.nj.gov/doh-shad/indicator/complete/Radon.html
The Radon Section, Bureau of Environmental Radiation, New Jersey Department of Environmental Protection was the source of data.
The number of tests was determined by looking at pre-mitigation tests conducted in residential buildings since January 1, 1992 and the end of the specified calendar year, ending with the year 2024.
Testing homes for radon had seen an improvement in the percentage of New Jersey homes ever tested for radon from 1996 (9.7%) to 2017 (32.5%). There was a slight decrease in the percent of homes tested in 2018 followed by a steady increase in testing since 2020. In 2024, the total homes tested was 36.9%. This exceeds the target goal for 2020 of 35% in the Health Initiative HNJ2020.
