Half-life of 230Th
Abstract
The half-life of 230Th was measured by the specific activity method. Alpha counting was done in a low geometry counter whose geometry factor was calculated from its dimensions. Sample weights were determined by isotopic dilution. Measurements were made on four isotopic mixtures ranging from 0.383 to 99.52% 230Th. The half-life is 75381+/-295 years. RADIOACTIVITY 230Th half-life, specific activity; measured: α activity by low geometry counter, thorium mass by mass spectrometric isotopic dilution.
