ABSORPTION AND GEOMETRY EXPERIMENTS IN GAMMA SPECTROMETRY OF URANIUM WITH A LARGE SCINTILLATION DETECTOR

摘要

Counting geometry and radiation absorption studies have been performed for point and bulk U-235-enriched uranium sources, using a 9-inch by 4-inch scintillation detector and untempered Masonite absorbers. The absorption data was collected for com¬parison with a mathematical computer model of the Y-12 In Vivo Radioactivity Measurement Facility counting arrangement.
