The use of low level LSC instead of g-spectroscopy allows reduced sample activity, shorter count rates and use of sample changer. This is of great advantage when many samples have to be measured during a short time period. The main nuclides of interest were 227Ac and 223Ra. 227Ac does not have any appropriate g-radiation, therefore measurements of the nuclei of interest must be based on a- and b-spectroscopy. In this study, it is shown that analyses of the radionuclidic purity of the liquid phases could be determined by a- and b-spectroscopy with Quantulus.展开更多
