Abstract
In this study, the dependence of TDCR Cerenkov counting technique on sample geometry, vial material and instrument type was studied. Various volume sets of color quenched samples spiked with yttrium-90, phosphorus-32, strontium-89, and bismuth-210 were prepared in 20-mL polyethylene scintillation (PE) vial, low-potassium borosilicate glass scintillation vial and 7-mL PE vial and then were measured by TDCR liquid scintillation analyzer (LSA), Hidex 300SL, Hidex 300SLL and LSA 3000. The results showed that in case of low color quench, dependence of TDCR Cerenkov counting technique on sample volume (in the volume range of 8–20 mL), vial type (7 and 20-mL) was negligible. The effect of vial material on the TDCR Cerenkov counting technique varied from decay energy of radionuclides and type of TDCR LSA. Additionally, TDCR Cerenkov curves of Hidex LSA agreed well with each other, and deviated from those of LSA 3000.
