- A shielded cell around a Na(Tl) crystal scintillation detector is described which was constructed of polyethylenelined paper bags containing 100 pounds each of crushed talc. The cell was 4 ft x 4 ft x 4 ft with 2-ft thick walls. Background in the talc cell ranged from about 200% at low energies to 160% at high energies of that obtained in a lead cell. The cost of the talc cell was about 20% of that of a lead cell. Use of the cell for counting whole-body gamma radiation in humans is described. (C.H.)
