Surface Contamination Measurements As an Index of Control of Radioactive Materials

Abstract

The purpose and the objections to surface contamination measurements are reviewed. The need for permissible values in this field is evident and the general basis of the derivation of the values in use in the United Kingdom is discussed. Surface contamination can provide an indicator of the degree of control which is being maintained over operations with radioactive materials and, in most cases, is a reliable indication of whether air monitoring is required.
