Abstract

A facility for the calibration of down-hole radiometric logging instruments has been constructed at the Australian Mineral Development Laboratories in South Australia. Three calibration models of a borehole passing through a zone of homogeneous uranium ore have been completed and are available to users. The radiometric grades determined for the models are 0.209%, 0.920% and 0.054% equivalent U3 O8.
