Abstract

Cherenkov counting of the ⁹⁰Sr-⁹⁰Y 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 ⁹⁰Sr-⁹⁰Y in human urine samples is described.
