Half-life measurements of lutetium-176 using underground HPGe-detectors
The half-life of 176Lu was determined by measuring the 176Lu 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)x10^10a could be calculated.
