Abstract
The transition by beta emission of 187Re to 187Os would offer an attractive method of determining geologic and cosmologic ages if the decay rate of 187Re was known. An improvement in the determination of the decay rate has been accomplished using an organic compound of rhenium in liquid scintillation counting that is monitored by standards of other pure beta emitting isotopes. The half-life of 187Re is estimated to be (3.5 ± 0.4) × 1010 yr.
