Abstract

¹²⁹I and ¹²⁷I concentrations in animal thyroids coming from several regions of Argentina were determined by accelerator mass spectrometry (AMS) and gas chromatography (GC), respectively. The measured ¹²⁹I/ ¹²⁷I ratios, ranging from 3×10 ^-12 to 4×10 ^-10, are significantly lower than those typical for areas in the northern hemisphere (10 ^-10-10 ^-7). The ¹²⁹I concentrations show a clear dependence with latitude and season, which can be understood considering tropospheric circulation patterns, possible ¹²⁹I sources and regional precipitation rates.
