O033700100019 DETECTOR (PROPC).The Majority of the Samples was Counted with O033700100020 An Argon-Methane Flow Proportional Counter Having a O033700100021 Very Thin Vyns Window (APPROXIM. 250 MUG/CM**2). O033700100022 (NAICR).Ag-112 was Counted with a 3 in. By 3 in. O033700100023 Na-I(TL) Crystal.

O033700100038 Rhodium-The Target was Dissolved in 70% Hclo(4), O033700100039 Carriers of Rh,Ru and Sr Added,and Equal Aliquots O033700100040 Withdrawn For Isolation of Rh and Sr.. O033700100041 Silver-As the Fractional Chain Yield of Ag-112 was to O033700100042 Be Determined,Ag was Isolated Twice from the Same O033700100043 Solution.Their Chemical Procedure is Based on Repeated O033700100044 Agcl Precipitations and Fe(OH)3 Scavengings.The SamplesO033700100045 Were Weighed,Mounted and Counted As Agcl. O033700100046 Cadmium-The Chemical Method Based on Precipitations of O033700100047 Cadmium-Rheineckate was Used with the Addition of Two O033700100048 Agcl Precipitations from the Original Fission Product O033700100049 Solution.The Isolation was Performed Two Days After theO033700100050 End of Irradiation.
