The half-life of 152 Eu was determined by measuring the disintegration rate of a 152 Eu sample and the number of 152 Eu atoms contained in the sample. The number of 152 Eu atoms was determined by isotope-dilution mass spectrometry, while the 152 Eu activity was measured by the 4πβ-γ spectroscopic coincidence method. The half-life obtained was 13.12 ± 0.10 yr.

This value was determined by following the decay of a mass-separated source over an 18-year period using a NaI(Tl) scintillation counter. We confirmed the stability of the counting system by measurement of 152 Eu, 154 Eu and 155 Eu half-lives during the same period.
