Curves relating exposure to thickness of subject for 2% radiographic sensitivity have been experimentally determined for the five isotopes Co/sup 60/, Ir/sup 192/, Cs/sup 137/, Tm/sup 170/, a nd Th/sup 228/. A medium speed fine grained film and a fast film were used in the radiographing of slotted iron wedges up to 9 inches thick and 2% sensitivity was obtained from 0.05 to 9 inches of iron. Aluminum wedges were also radiographed with Tm/sup 170/ and 2% sensitivity obtained from 0.04 to 3.5 inches. (auth)
