Keywords	tritium (3H) sampling / 3H baseline measurement / 3H transport model / 3H exposure / 3H transit times
Outline of Research at the Start	The research project plan is: Year 1-4: Monthly sampling of rain, river and spring water for tritium (3H) at selected headwater catchments to determine the main factors controlling spatial and temporal variation dynamics; Year 2-4: Modeling of 3H transit times, 3H circulation, and estimating 3H doses.
