In this paper, we present a study of the levels of tritium precipitation in Valladolid (Spain) based on measurements of samples collected during a period of three years. Seasonal variations in the 3H activity have been detected. The anomalous values with respect to the general trend are discused in terms of the synoptic conditions associated to the precipitation event.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/bookPart10.1016/B978-0-08-044648-6.X5000-9info:eu-repo/semantics/restrictedAccess
