Abstract
A method for the simultaneous ICP-MS determination of alpha- and beta- emitting radionuclides in acid digested samples of concrete without fu rther sample pretreatment is presented. Spectral and non-spectral inte rferences are corrected fol by combining systematic internal standardi zation with bilinear multivariate calibration. Consequently, especiall y for radionuclides with long half-lives, ICP-MS is an alternative to radiometric analytical methods. The optimal multivariate calibration a pproach is the PLS1-model with preselected variables.
