Rapid Determination of Rubidium in Cæsium Nitrate by Neutron Activation


DETECTION and determination of rubidium in cæsium nitrate by use of neutron irradiation followed by γ-scintillation spectrometry have been attempted. It is known that when natural rubidium is irradiated with neutrons, rubidium-86m (61 sec), rubidium-86 (18.7 days), and rubidium-88 (18 min) are formed. When any one of them is used for detecting rubidium, it is preferable that irradiation is continued for a period comparable with the half-life. Therefore, it was thought that the use of rubidium-86m offered a method for the rapid analysis for rubidium: this method has so far not been reported.
