Abstract

The principal objective of this research was to provide information on cost-effective techniques to detect localised areas of gamma-emitting radionuclides. This objective was achieved by determining the time required to scan unit area as a function of depth of the gamma source below the site surface, the activity of the gamma source, the energy of the emitted gamma-ray and the gamma transport properties of the site material. Survey and sampling techniques are compared, and the advantages of using survey techniques to detect localised gamma-ray sources are discussed. A survey technique based on an adaptive moving array detector system is described.
