Development of a reference method and sampling system for continuous monitoring of environmental HT and HTO concentration in the air. Final report for the period 15 December 1988 - 14 December 1990

Technical Report:

Abstract

A differential sampling system to monitor environmental Tritiated Water Vapour (HT) and Tritiated Hydrogen Gas (HTO) concentrations in the atmosphere was developed and tested. The sampler consists of an aerosol filter, diaphragm pump, absorption trap for HTO (molecular sieve), supply of H{sub 2} carrier (electrolysis unit), conversion trap for HT (Pd-impregnated molecular sieve), flow meter and gas meter. The sampler operates with a flow rate between 30 and 80 1/h, with a typical sampling period of one week. Vacuum desorption at high temperature is used to extract the HTO collected in the absorption and conversion traps. Tritium analysis is carried out using liquid scintillation spectrometry or gas proportional counting. The sampler is equipped with built-in safety systems and can operate in remote places. Refs, figs and tabs.
