Abstract

The temporal variability of ¹²⁹I in atmospheric samples taken between 1993 and 1999 in Seville (Spain) has been studied. Results show a good agreement with the history of the ¹²⁹I gaseous emissions of the reprocessing plants at Sellafield and La Hague. This suggests that these emissions are the origin of the ¹²⁹I present in the atmosphere in southern Spain. Apart from this, the similarity between the time evolution of gaseous ¹²⁹I and ¹²⁹I/¹²⁷I in 1998 would imply a fast chemical equilibration between ¹²⁹I from the reprocessing plants and stable iodine.
