Abstract

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.
