Activity standardization by means of liquid scintillation counting and determination of the half-life of 89Zr

Activity standardization of two enriched 40K solutions for the determination of decay scheme parameters and the half-life

“…It should be noted that the backscattering effect was not taken into account by Kossert and Günther (2004) and also Grau Malonda and Grau Carles (2002) did not mention such a correction. The method used here to take into account the photon backscattering effect has already been described in a paper on 89 Zr (Kossert et al, 2022), where the effect plays a much larger role.…”
