Abstract
Radioactive yttrium-90 separated from two aged samples of fission product strontium was allowed to decay. The change in activity was followed for more than 650 hours with standard mica-window beta counters. From the observed changes, the mean half-life of yttrium-90 was calculated to be 64.60±0.43 hours.Keywords
