WebTheβ-decay of Rb has been studied with a scintillation spectrometer. To avoide source absorption and scattering troubles we used RbJ(T1)- and NaJ(T1)+Rb J-resp. CsJ(Tl)+RbJ-crystals. Theβ-spectrum was measured down to 6 keV and the observed maximumβ-energy was found to be 275±5 keV. The specific activity of natural Rubidium was determined at … WebMay 21, 2010 · Rubidium (Rb-82), a nonreactor produced tracer, is believed to have superior accuracy compared to Tc-99m and Tl-201 SPECT, with 5-20 times lower radiation dose. In the U.S. Rb-82 generators have been FDA-approved since 1989 and are used increasingly for CAD diagnosis, but are still considered investigational in Canada.
