  "definition": "Distance over which population and other targets are evaluated. The target distance limit generally is a four-mile radius from the sources at the site. However, if a sampling point meeting the criteria for an observed release is located beyond the four-mile radius, that point defines the outer boundary of the target distance limit. For example, if an observed release is established six miles from the source, the target distance limit is six miles.",
