O158300100004 AUTHOR (M.Glaser, D.B.Mackay, A.S.O.Ranicar, S.L.Waters, O158300100005 F.Brady, S.K.Luthra) O158300100006 REFERENCE (J,RCA,92,951,2004) O158300100007 INSTITUTE (2UK HHL) O158300100008 SAMPLE The platinum disk containing enriched Te-124(99.3%) O158300100009 TeO(2) was fitted. The disk was covered with aluminum O158300100010 foil, 0.25-mm, held down by a clamping plate. An O158300100011 increase of the disk diameter from 10 mm to 20 mm O158300100012 increase the surface of the disk four time which O158300100013 reduces the power densities and allows a much more O158300100014 effective cooling. O158300100015 A 10 mm (Te-124) TeO(2) target disk, thickness of O158300100016 (Te-124)TeO(2)-191-mg/cm**2, was used for target O158300100017 yields in table 3. O158300100018 FACILITY (CYCLO,2UK HHL) A Scanditronix MC40 Mk II cyclotron O158300100019 CORRECTION Correction for loss from the distillation was made. O158300100020 DETECTOR (SCIN) The Bicron 400 plastic scintillator. O158300100021 (GELI) a co-axial GeLi detector for measurement radio- O158300100022 nuclidic purity. The system was calibrated for energy O158300100023 and efficiency using Eu-152 and I-125 sources. O158300100024 The radioactivity of I-124 was measured by an IG12 O158300100025 ionization detector.
