Abstract
The radionuclide 152Eu was produced by irradiating 151Eu2O3 or 151EuCl3 enriched to 98.9% with thermal neutrons. 152Eu was separated from rare-earth impurities by extraction chromatography on a column using 0.6 M nitric acid eluent. The specific activity of the 152Eu was 1-10 Ci/g of Eu. The impurity of the 154Eu did not exceed 0.1%. The activity standardization of 152Eu was carried out by extrapolation of 4 pi (beta, e, x)-gamma coincidences. The relative gamma-ray intensities for 28 gamma-ray energies emitted in 152Eu decay have been measured.Entities:
