The Safety Guide for the Application of the Concepts of Exclusion, Exemption and Clearance provides an elaboration on the use of the concepts of exclusion, exemption and clearance for establishing the scope of regulatory control. This safety report supports the Safety Guide and provides the basis for the activity concentration values for exclusion and exemption of bulk amounts of material, which can also be used for clearance. These criteria were developed using models that employ specific assumptions and parameters. This report derives radioactivity concentration levels for deciding whether a certain material should be excluded, exempted or cleared. |
