Techniques were developed for the introduction and quantitative determination of promethium-147 in liquid scintillator. Use of dimethyl-POPOP at optimum concentrations with other scintillator components facilitated the utilization of liquid scintillator for absolute standardization of the weak beta emitter promethium-147, and contributed to a sensitive bioassay procedure for analysis of the radioisotope. A minimum chemical separation and sample process time makes this technique most desirable for routine use. Urine samples were treated to remove colored organic components and finally extracted into the scintillator with di-2-ethyl hexyl phosphoric acid. The sensitivity of the method for a 10-minute sample count was about 2 x 10/sup -6/ mu c. (auth)
