Cerium-141 and cerium-144 are determined in the presence of each other by performing a suitable cerium chemical separation and then measuring the radiation from each nuclide. Cerium-144 is determined by counting the 3.0-Mev Pr/ sup 144/ beta ray: cerium-141 is determined by integrating beneath the 145-kev gammaray peak observed with a sodium iodide gamma-ray spectrometer. In the later case correction for coatributions from cerium-144 must be made. The gamma/ beta branchings for the 145-kev gamma ray in cerium141 and the 134-kev gamma ray in cerium-144 were determined.
