A method for providingC-labeled cyanides fromC labeled oxides in a target gas stream retrieved from an irradiated high pressure gaseous target containing O, whereinC labeled oxides are reduced with Hin the presence of a nickel catalyst under a pressure and a temperature sufficient to form a product stream comprising at least about 95%CH, theCHis then combined with an excess of NHin a carrier/reaction stream flowing at an accelerated velocity and the combinedCH4 carrier/reaction stream is then contacted with a platinum (Pt) catalyst particulate supported on a substantially-chemically-nonreactive heat-stable support at a temperature of at least about 900&#xb0; C., whereby a product stream comprising at least about 60% HCN is provided in less than 10 minutes from retrieval of theC labeled oxide.
