Abstract

The isotope Cs135 is quoted as having a half-life of 2.3 Myr. However, there are three published values ranging from 1.8 to 3 Myr. This research reviews previous measurements and reports a new measurement of the half-life using newly developed accelerator mass spectrometry (AMS) and inductively coupled plasma mass spectrometry (ICPMS) techniques along with β and γ radiometric analysis. The half-life was determined to be (1.6±0.6)×106 yr by AMS and (1.3±0.2)×106 yr by ICPMS with 95% confidence. The two values agree with each other but differ from the accepted value by 40%.
