摘要：

Precision measurements were made to determine the Ac-225 half-life. The Ac-225 loss in the samples was monitored using gamma- and gamma-ray spectrometry by the activity of daughter decay products occurring in radioactive equilibrium with the parent radionuclide. The Ac-225 half-life is 9.912 +/- 0.003 days. The result obtained was compared with the published data.
