Exhibit 2 shows radon potential in homes at the county level based on indoor radon measurements, geology, aerial radioactivity, soil permeability, and foundation type. Zone 1 is the highest radon potential area, followed by Zone 2 (medium), and Zone 3 (low). It has been reported anecdotally that radon vent fans and mitigation systems are also
Radon in Iowa is a pressing environmental health issue, given the state’s high potential for elevated radon levels. Iowa’s geological makeup, particularly its soil composition, contributes to these higher radon concentrations. This page is dedicated to informing residents about the risks, testing procedures, and mitigation strategies for radon in Iowa, emphasizing its importance for public
Map of Radon Zones in North Carolina based on Environmental Protection Agency (EPA) data. Highest Potential: counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones) Moderate Potential: counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)
FACT SHEET PURPOSE: •0- Sections 307 & 309 of IRAA directed EPA to list and identify areas of U.S. with the potential for elevated indoor radon levels •$• EPA's Map of Radon Zones assigns each of the 3141 counties in the United States to one of three zones based on radon potential: * Zone 1 counties have a predicted average indoor screening level greater than 4 pCi/L (red) * Zone 2
Geodata.epa.gov/radon is a website that provides an interactive map of radon zones in the United States. Users can explore the map by state, county, or zip code and learn about the potential health risks of radon exposure. The website also offers guidance on how to test and reduce radon levels in homes and buildings.
The USEPA radon zone maps are categorized by counties as zones 1, 2, or 3. In zone 1 the average indoor radon concentrations is expected to be greater than 4 picoCuries per liter (pCi/L). In zone 2, it is expected to be between 2 and 4 pCi/L and in zone 3, it is expected to be less than 2 pCi/L. Figure 1 (below) shows the radon zone map for
• Edificios nuevos: siempre, en términos municipales en Zonas 1 y 2* (ver mapa de las zonas abajo). • Intervenciones en edificios existentes: edificios existentes en estas zonas en los que se vaya a realizar una intervención de reforma que afecte a algún elemento constructivo que influya en la concentración de radón, así como a las ampliaciones y a las zonas del edificio afectadas

Highest Potential: counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones) Moderate Potential: counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)
ALABAMA Map of Radon Zones The U.S. EPA and the U.S. Geological Survey have evaluated the radon potential in the U.S. and have developed this map is to assist National, State, and local organizations to target their resources and to assist building code officials in deciding whether radon-resistant features are applicable in new construction.
