Measurement of the 177Lu Half-Life
The half-life of 177Lu was measured by following the decay of sources with an ionisation chamber and with a liquid scintillation counter over a period of 85 days and 42 days, respectively. The detector signals showed three major components: the decay of 177Lu, 177mLu and the background signal. The half-life value, T1/2(177Lu)=6.6465 (35) d, was obtained by a least-squares fit of two exponentials and a constant to the experimental data. The data was corrected for decay during the measurements. Residuals of the fit and uncertainty budgets are presented in this paper. The result is in agreement with three out of seven previously published measurement results and the currently recommended value of 6.647 (4) d (Kondev, 2002). A new recommended value of T1/2(177Lu)=6.6465 (27) d was obtained from a weighted mean of our results with a selection of literature data.
