New Jersey Radon Information

New Jersey Radon Program:

Radon Website: Website
Radon Contact: Anita Kopera
Active Radon Program: Yes
Require License for Radon Professionals: Yes

New Jersey is the fourth smallest state in terms of size, and yet it’s the 11th most populous. It also happens to be the most densely populated state in the country.

New Jersey does have an active radon program, dedicated to educating citizens about the risks associated with the deadly gas. You can find more information on Radon, testing and mitigation at the official page.

The radon levels in New Jersey are well above average in many areas of the state. As such, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

New Jersey Radon Levels

Map of New Jersey Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

New Jersey Radon Statistics

New Jersey has 21 counties and 7 (33%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. New Jersey's state radon zone average is 1.81, which is the average of all county zone ratings the EPA has assigned the state, ranking it 27 among all states.

New Jersey Radon Contractor License Information

Does New Jersey require contractors to be licensed? Yes.

What are the licensing requirements? The requirements are as follows:

1. Attend and complete an approved course.

2. Take and pass the New Jersey certification examination.

3. Turn in application along with proof of education, course completion, acceptable grades or scores and relevant fees.

For a more detailed list of instructions visit the official New Jersey page.

New Jersey Radon Real Estate Requirements

Does the state of New Jersey require radon testing for all real estate transactions? No

However both the state of New Jersey and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though New Jersey does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. New Jersey radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
