The counting of barium carbonate in a liquid scintillation spectrometer.

Abstract

A method is described for counting relatively large amounts of low specific activily BaCO/sub 3/ labeled with carbon-14. The tecchnique is simple, adaptable, and reproducible with an efficiency of 56 per cent for 200 mg of BaCO/ sub 3/. This technique obviates the need for low efficiency infinite thickness counting and replaces ioni zation chamber counting for most samples. (C.H.)
