Why should the EPA radon zone map not be used?

Using the EPA radon zone map to speculate radon levels can lead to misinterpretation of the actual conditions in specific homes or buildings. The map provides a generalized overview of radon potential across different geographic areas, but it does not account for local variations in soil composition, building construction, or ventilation practices that significantly impact radon levels. Relying solely on this map to estimate radon concentrations could result in either undue alarm or a false sense of security regarding radon risks in a particular location.

Instead, individual radon testing in homes and buildings is the most reliable method for determining actual radon levels, as it considers specific environmental and structural factors. This approach is essential for effectively assessing radon exposure risk and implementing appropriate mitigation measures when necessary.
