Is radon high in Camden, New Jersey?

Low. Averaging the model's ZIP-code predictions across Camden (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 0.8 pCi/L - about 53% below the US average of 1.8 and about 35% below the New Jersey average of 1.3. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Camden ranks 22 of 22 New Jersey cities on this site.

Which Camden ZIP codes have the highest radon?

Predictions for the 6 modeled ZIP codes in Camden range from 0.8 to 1.1 pCi/L in the basement. 0% of them are predicted at or above 4 pCi/L and 0% at or above 2. The city is fairly uniform, so the city-wide number is a reasonable guide for any neighborhood.

Should I test for radon in Camden?

Yes, once. The EPA recommends testing every home regardless of area. A short-term kit costs little and settles the question for your house; Camden's low predicted average describes the typical home, not yours.

What does EPA Radon Zone 2 mean for Camden?

Camden sits mainly in Camden County, which the EPA classifies as Zone 2 - moderate potential (2-4 pCi/L). The zone map dates from 1993 and covers whole counties. The newer model's city average of 0.8 pCi/L does not line up with Zone 2, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.

Radon levels in Camden, New Jersey

LowEPA Zone 2

Predicted long-term basement average of 0.8 pCi/L (model estimate) across the 6 modeled ZIP codes in Camden - about 53% below the US average of 1.8, about 35% below the New Jersey average of 1.3. Ranked #22 of 22 New Jersey cities on this site. Most of the city lies in Camden County.

Test Camden, NJ once anyway - radon varies house to house

The predicted basement average here is 0.8 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Camden

The typical Camden home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 0.8 to 1.1 pCi/L.

The city figure is not a separate estimate: it is the mean of the model's ZIP-code predictions, weighted by the share of the city's land in each ZIP (Census 2020 ZCTA-to-place relationship file). Note that the EPA classifies Camden County as Zone 2 while the newer model predicts 0.8 pCi/L for Camden; where they disagree, we grade on the model but show both.

Comparable New Jersey cities: Jersey City (0.9), Hoboken (1.0), Paterson (1.0), Elizabeth (1.0).
