Abstract

The half-life of Lu-176 was determined by measuring the Lu-176 activity in metallic lutetium foils. Three different HPGe-detectors located 225 m underground were employed for the study. Measurements using the sum-peak method were performed and resulted in an average massic activity of 52.61±0.36 Bq•g-1. The foils were of natural isotopic abundance so using the massic activity and the value of the natural isotopic abundance of 2.59±0.01%, a half-life of (3.722±0.029) 10^10 yr could be calculated.
