URANIUM ANALYSIS BY GAMMA ABSORPTIOMETRY
The major advantages of the absorptiometer as compared to the x-ray photometer are the dependability and simplicity of the source, essentially monochromatic emission, and low cost. The Am/sup 241/ gamma absorptiometer is limited to special applications as compared to the general purpose x-ray photometer. For example, the Am/sup 241/ absorptiometer has a 1.5% standard deviation at 5 g/l, compared to 0.7% for the x-ray photometer. Also the x-ray photometer can tolerate 10/sup 7/ times greater sample gamma activity before a 1% error would be induced at 5 g/l uranium. On the other hand, the Am/sup 241/ gamma absorptiometer has a very real advantage where an additional analytical instrument is needed in the laboratory or operating plant to couple closely with an experiment or process. The cost of the gamma absorptiometer is relatively low. The gamma absorptiometric technique has found application in the plant and the laboratory, where as limitations were not serious and its simplicity advantageous. (auth)
