Validation Of A Model For Nonintrusive Depth Estimation Of Buried Radioactive Wastes

This paper presents improved results using a Cadmium Zinc Telluride (CZT) detector for a recently developed image-based nonintrusive depth estimation method for buried radioactive wastes. It showed that the use of the CZT detector resulted in an improved maximum detectable depth of 18 cm with a significantly lower average count rate of 14 cps compared to the maximum detectable depth of 12 cm with an average count rate of 100 cps previously obtained using an organic liquid scintillator.
