Long term uncertainty method used to evaluate ICSI tritium laboratory’s proficiency test results

Abstract

Article info:Results obtained for proficiency tests during 2000-2017 period are used to verify and validate measurements method of tritium specific activity in aqueous samples. The longterm uncertainty method (LTUM) was applied to Tritium Laboratory results in order to identify the constant and proportional bias effects, stability of the laboratory routine procedure, and total error of the measurements.

The Impact of Experimental Pilot for Tritium and Deuterium Separation Activity on Tritium Level in the Atmospheric Water Vapor of Icsi Tritium Laboratory

“…The reference value represents the maximum tritium activity concentration recorded in water vapour of the atmosphere, during the PESTD preoperational program (Varlam et al, 2011). The tritium laboratory performed tritium measurements of aqueous samples received from different intercomparison exercises without monitoring the lab atmosphere, and the good results obtained prove the good stability of the routine procedure over more than 17 years of observations (Varlam et al, 2020). If the measured tritium activity concentration of the lab atmosphere is higher than the imposed limit, corrective measures are applied according to internal procedures.…”
