Abstract
For the estimation of the tritium activity in environmental samples, the triple to double coincidence ratio (TDCR) method is standardized for the liquid scintillation counter (LSC). Variation of TDCR with tritium activities, optimization of the region of interest for low-level measurement of tritium, the effect of different quenching agents on the TDCR values, and application of TDCR method for the quantification of ionization quench factor (kB) are discussed in this paper. Relative standard deviation in TDCR values at tritium activity levels of 15–140 Bq/L is found to be less than 1%. The the quench curve equation does not depend on the type of quenching agents.
