Proper calibration of portable gamma-ray spectrometers and Spectrometric logging equipment is essential if they are to be used for accurate quantitative determinations of radio element concentrations. In the case of both types of equipment, it is necessary to determine the system calibration constants (stripping factors and sensitivities). In the case of borehole logging equipment, it is further necessary to determine the system response characteristics if the data are to be computer processed to improve the accuracy and resolution of the logs.
Facilities are now available near Ottawa for the complete calibration of portable gamma-ray spectrometers and Spectrometric logging equipment, in addition to already existing facilities for calibrating airborne gamma-ray spectrometers. Limited additional facilities are also available or planned in several other areas of Canada.
