This map from the EPA shows where elevated levels of radon have been discovered in New York and categorized into 3 zones based on these predicted average indoor radon levels which are measured in picocuries per liter pCi/L:
- Zone 1: >4 pCi/L (highest)
- Zone 2: 2-4 pCi/L
- Zone 3: <2 pCi/L
No matter which zone you live in, your home may be exposed to elevated levels of dangerous radon gas. This map is based on averages so even if you’re in Zone 3, it’s a good idea to have your home tested for radon for the safety of your family. Syracuse and Onondaga County are in the Zone 1 area, so Radon testing is very important as the EPA recommends levels be below 4 picocuries per liter. Radon can enter the home through the hole in your floor, where sump pumps are located.
A properly installed radon mitigation system works by creating a vacuum under the basement or crawl space floor and venting the radon gasses to the exterior of the home. A radon resistant barrier is generally used in a crawl space area. In Onondaga County, residents can obtain a free test kit to test their homes for radon. They can simply follow the instructions and mail the test kit in to get the test result.
The average cost for a short term (48 Hours) professional radon test is generally $100-$200.
