A novel portable grab sampler for tritiated water vapor.
The purpose of this work was to evaluate the applicability of a recently developed portable high-throughput liquid-absorption air sampler for measuring tritiated water vapor concentrations in nuclear facilities.
A procedure for sampling tritiated water with a portable high-throughput liquid-absorption air sampler and measuring its concentration in air was developed with the aid of a theoretical model.
Tritium concentrations in the air of a heavy water reactor currently being decommissioned, derived from samples obtained with a portable high-throughput liquid-absorption air sampler, a bubbler, and a cold trap, yielded comparable results, suggesting the applicability of the portable high-throughput liquid-absorption air sampler to tritium grab sampling.
