Description

A method was proposed to measure β+-activities of radionuclides emitting almost no γ-rays by detecting 511 keV annihilation γ-rays with a Ge detector. The β+-sources with maximum energies up to about 3.4 MeV can be regarded as 511 keV point γ-sources, if the sources are set between two 10 mm thick acrylic plates. The effect of diffused annihilation positions of β+-particles in the absorber on detection efficiencies was observed to be negligible with an accuracy of 1.0%. (orig.)
