Abstract

In this study, for the measurement of 3H(tritium) radioactivity concentration, a study was conducted on whether the type of cocktail and the material of the vial had an effect on the measurement before liquid scintillation counter measurement on HTO-type samples that had undergone physical and chemical pretreatment. As a result of the study, the efficiency according to the type of cocktail was higher in Ultima Gold LLT than Ultima Flo-AP cocktail with polyethylene (1.49%), glass (5.10%), and teflon (6.58%), respectively. Regarding the effect according to the type of vial, the efficiency and SQP(E) of both Ultima Gold LLT and Ultima Flo-AP showed the highest values in the order of teflon, polyethylene, and glass.
