    We here present the most extensive data set on the distribution of 127I and 129I in precipitation (rain and snow) covering the period 2000–2006 and European latitudes 55°N–68°N. Our results indicate a wide variation in the concentrations and fluxes of the two isotopes associated with generally higher values at near coastal sites compared to the inland ones. Total wet-related annual deposition of 127I and 129I on Sweden and Denmark is estimated at about 1.2 × 109 g and 60 g respectively. The average annual 129I wet deposition accounts for
