Standardisation of (56)Co and (57)Co using software coincidence counting system.

Abstract

Activities of the radionuclides (56)Co and (57)Co were determined by the efficiency extrapolation method applied to 4pi(PC)-gamma coincidence counting. Solutions of (56)Co usually contain a significant amount of (57)Co and (58)Co, so the measured activity of (56)Co requires correction. When the conventional coincidence method is used for (56)Co… (More)
