The 129I content in precipitation, lake and river waters sampled in Ireland in 2005-2006 has been determined by accelerator mass spectrometry. In the case of lake and river waters, the data reveal little if any geographic dispersion with a mean (n = 14) concentration of 4.6 ± 1.2(1σ) × 108 atoms L-1. In contrast, concentrations of 129I in precipitation show significant variations both in time and space, with concentrations ranging from a low of 1.9 × 108 atoms L-1 to a high of 303 × 108 atoms L-1. These variations in precipitation are attributed to temporal changes in on-going discharges of 129I from west European reprocessing plants in conjunction with the trajectories of airstreams prevailing over Ireland at the time of sampling.
