Determination of 129I/ 127I in aerosol samples in Seville (Spain)

In this work we present results of the 129I/ 127I ratio in aerosols of Seville, Southwest of Spain (37.4°N,6°W). 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 Zürich. We have...

Description
Summary:In this work we present results of the 129I/ 127I ratio in aerosols of Seville, Southwest of Spain (37.4°N,6°W). 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 Zürich. We have found the possibility of monitoring the 129I/ 127I isotopic ratio on a two-days basis with sensitivities in the order of 10 4–10 5 atoms 129I/m 3, and values of 10 −8–10 −9 for the isotopic ratio.
