Liquid Scintillation Counting Counting of Aqueous Solutions of Carbon-14 and Tritium

J. Shapira, William H. Perkins

Abstract

A method is reported whereby aqueous solutions containing weak beta emitters are dispersed as stable emulsions in liquid scintillator counting solutions. This permits the routine counting, with about 10-percent efficiency, of large numbers of samples containing tritium. Self-absorption does not present a problem when less than 5 percent aqueous phase is present.
