| Abstract: | The activity of the pure beta-emitter phosphorus-33 (P-33) has been directly determined by the triple-to-double coincidence ratio (TDCR) efficiency calculation technique, thus extending the number of radionuclides that have been standardized by this simple, non-extrapolation liquid scintillation (LS) method. The major advantage of inherently accounting for chemical quenching without the need for additional external measurements is demonstrated. The P-33 solution activity concentration was verified by tracing with cobalt-60, utilizing 4pi(LS) beta-gamma coincidence counting. Agreement to within 1.2% confirmed the reliability of the TDCR measurements. |
