Abstract

Within the last ten years there has been increasinginterest in tritium behaviour and distribution in the environment.This is based partly on empirical findings that tritium dischargedmostly as HTO can become transformed into organic forms in environmentalsamples. An international workshop was convened in France in 2012 togather the scientific community interested in organically boundtritium to share their experience and to establish a current stateof knowledge. This paper summarises the outcome of the workshop,which aimed to improve skills concerning OBT (OrganicallyBound Tritium) determination, transfer and behaviour in the environment.In order to improve OBT measurement credibility,it was decided to conduct and promote OBT analysisthrough inter-laboratory exercises. This practice will reduce uncertaintyin OBT analysis results, providing better OBT modelvalidation data and public dose assessments.
