Description:
In this work we present results of the ^1^2^9I/^1^2^7I ratio in aerosols of Seville, Southwest of Spain (37.4^oN,6^oW). A radiochemical method is applied to extract the iodine from the aerosols and prepare samples to be measured by accelerator mass spectrometry (AMS) at the ETH facility in Zurich. We have found the possibility of monitoring the ^1^2^9I/^1^2^7I isotopic ratio on a two-days basis with sensitivities in the order of 10^4-10^5 atoms ^1^2^9I/m^3, and values of 10^-^8-10^-^9 for the isotopic ratio.
