Abstract

The activity concentration of an 88Y solution was measured by means of a new custom-built 4πβ(LS)-γ coincidence counting system. Efficiency variation was carried out using chemical quenching and neutral density filters. A relative uncertainty of 0.57% was obtained for the activity concentration. Details of the measurements and of the analysis, as well as possibilities to reduce the uncertainty are discussed. Additional validation measurements were carried out by means of the well-established coincidence counting technique using a proportional counter (PC) in the β channel. The results of both coincidence methods were found to be in excellent agreement.
