  • Abstract
    The aim of this study was to introduce a new concept for measuring the remaining radioactivity in the 68Ga eluate or in the final radiopharmaceutical product. 68Ge decays to 68Ga through electron capture (EC, 100%). Using the 9.24 keV K X-rays of 68Ga following the EC of 68Ge the remaining 68Ge radioactivity in the 68Ga eluate can be measured with a gas proportional counter.
