Final answer:
To check for radon on a proposed site, you would use a radon map. Radon maps provide information on the average radon levels in a specific area or region. By consulting a radon map, you can determine if the proposed site is located in an area with a higher risk of radon.
Step-by-step explanation:
To check for radon on a proposed site, you would use a radon map. Radon maps provide information on the average radon levels in a specific area or region. By consulting a radon map, you can determine if the proposed site is located in an area with a higher risk of radon. For example, in the United States, the Environmental Protection Agency (EPA) provides a National Radon Risk Map that shows the predicted radon levels for each county. This map can help homeowners, builders, and regulators make informed decisions about radon mitigation measures. By using a radon map, you can identify areas where radon levels are higher and take appropriate steps to test and mitigate radon in the proposed site.
