Volume Optimization for Activity Determination of Tritiated Water Samples by Liquid Scintillation Counting
- 1. Radiation Protection, Nuclear Research Center Negev, Beer Sheva (Israel)
Description
The method for determination of tritium activity in water samples by Liquid Scintillation Counting has been validated in our laboratory for accreditation to ISO 17025. The validation process included a renewed examination of the method with relation to the accuracy, precision, selectivity, stability, linearity and detection limit. The present work focused on determination of the optimal volumes for the samples preparation. It included the optimization of the total volume of the sample, and of the ratio between the volume of the sample and of the liquid scintillator. For determination of the optimal values, we have tested several parameters: the counting efficiency (which depends on the quenching in the sample and the counting geometry), the background and the minimum detectable activity
