Abstract

To estimate the environmental transfer of tritium into the atmosphere and to establish tritium analysis techniques, this study improves our previous compartment model and proposes new analytical technique based on the microwave heating method and a water-sample purification technique using ion resin. This article introduces a new conceptual approach for estimating environmental tritium behavior.

Keywords

environmental tritium transfer, compartment model, environmental tritium analysis, soil-water transfer, microwave heating method, simple water-purification, small amount water sample
