Half-life measurement of the medical radioisotope 177Lu produced from the 176Yb(n,γ) reaction

Half-life measurement of the medical radioisotope 177Lu produced from the 176Yb(n,γ) reaction

177Lu is a medium energy beta-emitter commonly used in Nuclear Medicine for radiotherapeutic applications. In this work, the half-life of 177Lu has been measured using a re-entrant ionisation chamber over a period of 82 days (approximately 12 half-lives). Unlike the majority of previous studies, the...
