Abstract
In 2007/2008 the Institute for Reference Materials and Measurements (IRMM) organised an interlaboratory comparison (ILC) on the determination of 226 Ra, 228 Ra, 234 U and 238 U activity concentrations in mineral water. This paper describes the determination of the reference values for the activity concentrations of 234 U and 238 U by radiochemical separation and α-particle spectrometry performed at two independent laboratories. The experimental uncertainty of the reference values is discussed in detail.
