Development of an organically bound tritium standard

Applied Radiation and Isotopes, 2004
High-concentration factors between seawater and marine organisms have been observed for organically bound tritium (OBT). The absence of an available OBT standard impedes the validation of an analytical method for environmental samples. This paper describes the secondary standardisation of tritiated thymidine, which was chosen to act as an OBT standard,

Current understanding of organically bound tritium (OBT) in the environment

Journal of Environmental Radioactivity, 2013
It has become increasingly recognized that organically bound tritium (OBT) is the more significant tritium fraction with respect to understanding tritium behaviour in the environment. There are many different terms associated with OBT; such as total OBT, exchangeable OBT, non-exchangeable OBT, soluble OBT, insoluble OBT, tritiated organics, and buried ...

Organically bound tritium (OBT) for various plants in the vicinity of a continuous atmospheric tritium release

Journal of Environmental Radioactivity, 2008
In order to quantify tritium impact on the environmental, we studied vegetation continuously exposed to a tritiated atmosphere. We chose lichens as bio-indicators, trees for determination of past tritium releases of the Valduc Centre, and lettuce as edible vegetables for dose calculation regarding neighbourhood.

An improved combustion apparatus for the determination of organically bound tritium in environmental samples

Applied Radiation and Isotopes, 2016
This paper reports an improved combustion apparatus for the determination of organically bound tritium in environmental samples. The performance of this apparatus including the recovery rate and reproducibility was investigated by combusting lettuce and pork samples.
