Abstract
Possibilities of radiometric determination of Rb in liquid and solid samples using87Rb are discussed. In spite of the relatively low β-ray energy of87Rb, it is possible to achieve relatively high total counting efficiency (up to 75%) using gas flow GM counters. This fact makes possible to use the natural instability of87Rb also for the purposes of calibration. In this paper the conditions of radiometric determination mainly of small amounts of Rb are described (minimum measurable amount is 0.07% of Rb).87Rb can be used for the minimum activity determination by measuring β-radiation in the interval of energy of 0.27 MeV.
