Applied Radiation and Isotopes, 1995
Abstract In order to estimate the environmental tritium level retrospectively, the authors tried to establish a simplified and sensitive method for determination of organically bound tritium in tree rings. Organically bound tritium as low as approx. 1 Bq L−1 was determined with sufficient reproducibility, after combusting 25 g of dried wood without ...

Activation of Organically-Bound Tritium by Tritiated Water in Soil
2019The fate of tritium in the environment is a target of interest in many studies. However reported concentrations of organically bound tritium (OBT) in soil are not well understood. In this study, a supplementary non-biological process of soil OBT activation in the environment was explored.

Evaluation of combustion system for organically bound tritium analysis using dried fish samples
Radiation Protection DosimetryAbstract The combustion process of the organically bound tritium (OBT) analysis method is difficult and requires sophisticated techniques. For ease, safety, and reproducibility a semi-automatic combustion system was developed. An arbitrary combustion program that prevents sudden ignition was devised and combustion tests were conducted ...
