Abstract : Tritium deposition in rainwater at Ottawa, Canada, is reported for the years 1953-1959. Correlation with the tritium content of drainage water in the district has allowed study of the hydrodynamics of the water system. A turnover rate constant of 0.27/year has been found for a storage reservoir of 2.1 m. The fraction of fresh precipitation in re-evaporated water has been estimated as 0.55 = 0.1. A deposition rate of cosmic tritium of 1.3 = 0.1 atoms/sq cm sec has been obtained from early data. (Author)
