摘要：

The current interest in the use of Ir-192 for brachytherapy prompted a re-evaluation of existing half-life values. Using the evaluation criteria adopted in a recent IAEA-Coordinated Research Programme, it was determined that the uncertainty in the half-life obtained by evaluating published data spanning the last 20 years is too large. Further measurements of the half-life have been carried out using high-pressure re-entrant ionization chambers. The results of these latest measurements are presented together with a re-evaluation of the half-life using the IAEA-CRP criteria. The recommended half-life of Ir-192 is 73.830 +/- 0.018 d.
