title: Establishment of a method for the rapid measurement of gross alpha and gross beta activities in sea water.
abstract: The risk associated with NORM and with their redistribution in the environment due to human activities requires rapid methods which can be applied to a wide range of samples. The present work studies the effect that salts present in sea water have in the gross alpha/beta determination using low-level liquid scintillation counting and a new method is established. This is done from a previously established method for such determinations in non-saline water. External quenching parameter, efficiency, spectra position and interference values are evaluated to look for differences in matrix behaviour. Some quality parameters of the new method are reported.
