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.
天然放射性核素及其因人类活动导致在环境中重新分布所带来的风险，需要能够应用于多种样品的快速方法。本研究探讨了海水中盐分对使用低本底液体闪烁计数法测定总α/β放射性的影响，并建立了一种新方法。该方法是在先前用于非盐水此类测定方法的基础上建立的。评估了外部猝灭参数、效率、光谱位置和干扰值，以寻找基质行为的差异。报告了新方法的一些质量参数。
