Cherenkov counting of the (90)Sr-(90)Y pure beta emitters in aqueous samples is an attractive method; but color quenching correction is needed, this being especially significant for urine which is characterized by a strong coloration. A quench correction method based on the external source of some liquid scintillation systems (named ESAR-External Source Area Ratio) was proposed for aqueous solutions. In the present work, the application of the ESAR method for determination of (90)Sr-(90)Y in human urine samples is described.
切伦科夫计数法用于测定水性样品中（90）Sr - （90）Y纯β发射体是一种有吸引力的方法；但需要进行颜色淬灭校正，这对于具有强烈颜色的尿液尤为重要。针对水溶液提出了一种基于某些液体闪烁系统外部源的淬灭校正方法（称为ESAR - 外部源面积比）。在本工作中，描述了ESAR方法在测定人尿样中（90）Sr - （90）Y的应用。
