In practice, however, priorities for specific sites also often are influenced by public concern and political considerations. An early assessment a scoping analysis—of the relative significance of a particular site for dose assessment should include both radiologic and epidemiologic scoping studies.

And the decision to conduct a study must admit the possibility of a negative outcome obtained by credible and justifiable scientific procedures. There should be a series of decision gates selected somewhat arbitrarily, but applied consistently in three areas: the size and structure of the population; the relative size of the estimated dose compared with doses measured at other facilities; and whether anticipated risks exceed regulatory acceptability or are below the doses generally accepted as being of low consequence by authoritative bodies responsible for the protection of human health.

Third, the statistical requirements for a meaningful epidemiologic assessment must be met and these requirements should be based on the size of the population, estimated doses, quality and availability of records, and other factors. Fourth, a radiologic assessment should involve an iterative procedure for making dose estimates that increase in detail, once specific minimum dose criteria are exceeded.

Sites that pass the decision criteria, but still rate low on both scales would receive the lowest priority and could be -dropped from further detailed studies. For example, for a large population that is concerned but has received relatively low doses, an epidemiologic study designed to detect health effects might not be feasible.
