Pennsylvania Radon Levels

Pennsylvania has a user submitted radon level of 9.67. This is based on data submitted from visitors on our site. Learn more here.

EPA Radon Levels

Pennsylvania has 67 counties and 49 (73%) 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. Pennsylvania's state radon zone average is 1.28, which is the average of all county zone ratings the EPA has assigned the state, ranking it 9 among all states.

The radon levels in Pennsylvania are above average in many areas of the state. More than 61% of all homes tested in the state have been found to have elevated radon levels above the EPA recommended action level. There’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Pennsylvania Radon Contractor License Information

Does Pennsylvania 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 Pennsylvania 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 Pennsylvania page.

Those looking for a radon certification can take qualified third party courses offered by the NRPP or AASRT. The state will then endorse said professionals and add them to the official directory.


Pennsylvania Radon Real Estate Requirements

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

However both the state of Pennsylvania and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Pennsylvania 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. Pennsylvania radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.


Pennsylvania Radon Map

Map of Pennsylvania 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.
