The Simultaneous Determination of Ruthenium and Osmium by A Radiochemical Method

A simple radiometric procedure is proposed for the determination of raicrogram amounts of ruthenium and osmium by the use of neutron activation. Alter irradiation, the tetroxides of both metals were collectively distilled and then determined directly by measuring the photopeak areas of osmium-191 and ruthenium-103 at 45 and 498 Kev respectively. The effect of Compton continua was negligible.
