Stockholm natural tritium measurements. I

Abstract

After a brief description of our methods and standards for the determination of tritium in natural water, results are reported on the controversial rain water samples from Valentia, Ireland. The main part of this paper is a selection of tritium and deuterium data on samples, which may have general geophysical interest. Among them are long series of monthly precipitation from global and Scandinavian networks, and samples from rivers feeding into the Baltic.
