Abstract :
IRMM participated in a recent international comparison for the standardisation of a 204Tl solution organised by BIPM. The activity concentration of the 204Tl solution was measured at IRMM using 3 independent methods; Liquid Scintillation Counting using the CIEMAT/NIST method, 4π-CsI counting and 4πβ counting using a large pressurised proportional counter. This article describes the measurements in detail and discusses potential problems in the standardisation of 204Tl.
