However, the risk of contamination of the detector with traces of the much longer lived mother isotope 83Rb(T1/2 = 86.2 d) has to be ruled out. In this work the release of 83Rb atoms from a 1.8 MBq 83Rb source embedded in zeolite beads has been investigated. To do so, a cryogenic trap has been connected to the source for about 10 days, after which it was removed and probed for the strongest 83Rbγ-rays with an ultra-sensitive Germanium detector.
