Practical aspects of the application of cherenkov counting method with the correction of sample’s color quenching

Cerenkov counting is a convenient and effective method of high-energy beta radiation, which has long been used to measure number radionuclides, such as, in particular, 90Sr+90Y, environmental objects. The traditional requires the use radiochemical sample preparation procedures, but these procedures may be simpler than those used, for example, liquid scintillation (LSC) method. We proposed Cerencov method, corrects color quench effect. based on correlation between rates radiation its external standard, observed wide range quenching samples. allows measurement -emitters, as an express study 90Sr+90Y surface water. For cases, makes it possible avoid lasting expensive procedures. results cross-testing samples obtained by direct are good agreement with each other.
