O158200100003 AUTHOR (H.L.Sharma, J.Zweit, S.Downey, A.M.Smith, A.G.Smith) O158200100004 REFERENCE (J,JLCR,26,165,1989) Symposium Abstracts O158200100005 REL-REF (I,A0360001,H.Sharma+,J,ARI,37,105,1986) - details of O158200100006 experiment. O158200100007 INSTITUTE (2UK BIR,2UK MAN) O158200100008 FACILITY (CYCLO,2UK BIR) O158200100009 METHOD (EXTB) O158200100010 -the radiochemical separation of I-124 from O158200100011 natural Sb was by distillation of iodine using conc. O158200100012 sulphuric acid saturated with sodium nitrite as a O158200100013 solvent for the target, CCl(4) as a trap and 100 mug O158200100014 of KI as a carrier. O158200100015 -in the separation of I-124 from enriched Te-124 O158200100016 target, the same procedure is used except that only O158200100017 sulphuric acid is used to dissolve the target. The O158200100018 distillation procedure takes about 30 minutes and at O158200100019 the end of this period over 90% of the I-124 distils O158200100020 into the CCl(4) trap. Finally I-124 is extracted from O158200100021 CCl(4) with 0.5 ml of 0.01 M NaOH solution. O158200100022 (EDEG) the deuteron beam of 20 MeV available from the O158200100023 cyclotron is degraded in energy to 15 MeV by using highO158200100024 purity Al foils. The energy window used for the O158200100025 production of I-124 is from 15 to 8 MeV. O158200100026 DETECTOR (GELI) O158200100027 (HPGE) in the case of I-125 measurement. I-125 was O158200100028 monitored by comparing the ratio of the 28 keV iodine O158200100029 X-ray to the 35 keV gamma-ray of I-125 in a pure I-125 O158200100030 sample and in the produced I-124. O158200100031 CORRECTION The data was corrected for decay occurring between O158200100032 EOB and counting times.
