The Federal EPA And Radon Gas
Federal, State, and County EPAs All Monitor "The Invisible Killer"
The Federal EPA scientists create potential radon maps by combining a variety of data, such as the locations of rocks containing high levels of uranium, locations of fractures, aero-radioactive data, soil data on permeability and radon content, and indoor radon data. These types of radon data "heat maps" are available for every state in our nation.
Zone 1: Highest Radon Potential (greater than 4 pCi/L) - Radon Mitigation MUST BE Installed By A Licensed Professional.
Zone 2: Moderate Radon Potential (from 2 to 4 pCi/L) - Radon Mitigation SHOULD STILL BE Installed By A Licensed Professional.
Zone 3: Low Radon Potential (less than 2 pCi/L) - A Radon Mitigation System Does Not Need Installed.
The State EPA And Radon Issues In Ohio
2/3 of Ohio Is Tested In Zone 1, The Most Severe Radon Level
The U.S. EPA and the U.S. Geological Survey have evaluated the radon potential in the U.S. and have developed this map to assist Ohio and county organizations to target their resources and to assist building code officials in deciding whether radon-resistant features are applicable in new construction and existing housing/apartments.
This map is not intended to be used to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested regardless of geographic location.
The map assigns each of the 88 counties in Ohio to one of three zones based on radon potential. Each zone designation reflects the average short-term radon measurement that can be expected to be measured in a building without the implementation of radon control methods. The radon zone designation of the highest priority is Zone 1.
Zone 1: Highest Radon Potential (greater than 4 pCi/L) - Radon Mitigation MUST BE Installed By A Licensed Professional.
Zone 2: Moderate Radon Potential (from 2 to 4 pCi/L) - Radon Mitigation SHOULD STILL BE Installed By A Licensed Professional.
Zone 3: Low Radon Potential (less than 2 pCi/L) - A Radon Mitigation System Does Not Need Installed.
All 88 Ohio Counties By State pCi/L Levels
Should My Family Be Worried About The County We Live In?
Attached below is a document showing maps of geometric mean indoor radon concentrations (picocuries of radon per liter of air, or listed as pCi/L by the EPA) for ZIP codes in each of Ohio's 88 counties. The maps are ordered alphabetically by county name.
Highest Radon Potential (greater than 4 pCi/L) - Radon Mitigation MUST BE Installed By A Licensed Professional.
Moderate Radon Potential (from 2 to 4 pCi/L) - Radon Mitigation SHOULD STILL BE Installed By A Licensed Professional.
Low Radon Potential (less than 2 pCi/L) - A Radon Mitigation System Does Not Need Installed.
