| Nosaukums | <p>This document specifies a method by liquid scintillation counting for the determination of tritium activity concentration in samples of marine waters, surface waters, ground waters, rain waters, drinking waters or of tritiated water ([<sup>3</sup>H]H<sub>2</sub>O) in effluents.</p> <p>The method is not directly applicable to the analysis of organically bound tritium; its determination requires additional chemical processing of the sample (such as chemical oxidation or combustion).</p> <p>With suitable technical conditions, the detection limit may be as low as 1 Bq·l<sup>−1</sup>. Tritium activity concentrations below 10<sup>6</sup> Bq·l<sup>−1</sup> can be determined without any sample dilution.</p> |
