Interlaboratory radiochemical analysis comparison on a primary waste flux

An accurate knowledge of the inventory of long-lived and radio-toxic α, β and γ emitting radionuclides present in radioactive waste is a critical parameter for a reliable categorization of the waste in compliance with the existing disposal site regulations. Therefore, it is very important to have access to reliable radiochemical and radioanalytical procedures which provide results with a high accuracy. The objective of the project was to perform an interlaboratory radiochemical analysis campaign on the destructive measurement of radio-toxic and long-lived alpha and beta radionuclides in a primary waste flux.
