    Comparison of ZnS(Ag) Scintillator and Proportional Counter Tube for Alpha Detection in Thin-Layer Chromatography by Marc Pretze, Jan Wendrich, Holger Hartmann, Robert Freudenberg, Ralph A. Bundschuh, Jörg Kotzerke, Enrico Michler

    Published 2024-12-01
    “…(1) <b>Background</b>: Targeted alpha therapy is an emerging field in nuclear medicine driven by two advantages: overcoming resistance in cancer-suffering patients to beta therapies and the practical application of lower activities of <sup>212</sup>Pb- and <sup>225</sup>Ac-labelled peptides to achieve the same doses compared to beta therapy due to the highly cytotoxic nature of alpha particles. However, quality control of the <sup>212</sup>Pb/<sup>225</sup>Ac-radiopharmaceuticals remains a challenge due to the low activity levels used for therapy (100 kBq/kg) and the formation of several free daughter nuclides immediately after the formulation of patient doses; (2) <b>Methods</b>: The routine alpha detection on thin-layer chromatograms (TLC) of <sup>212</sup>Pb- and <sup>225</sup>Ac-labelled peptides using a MiniScanPRO+ scanner combined with an alpha detector head was compared with detection using an AR-2000 scanner equipped with an open proportional counter tube. …”
