  • Abstract
    A system which measures the absorption of the gamma radiations of Cobalt-60 in various materials is described. A thickness measurement device has been included in the system so that density (or specific gravity) of the sample materials may be automatically calculated. Accuracies of ± 0.03 per cent for the specific gravity measurement are obtained.
