Environmental radioactivity
After the Fukushima accident, large amounts of radionuclides were discharged to the atmosphere. Some of them travelled long distances and were detected in places as far from Japan as Spain a few days after the accident. One of these radionuclides was I. Its isotope I (T1/2 = 15.7 × 106 years) was also expected to follow the same pathway. In this work, we present the results for the I concentration in the same atmospheric samples from Seville (Spain) where I activity was measured in 2011 by Baeza et al. (2012). I concentrations in aerosol and gaseous samples showed concentrations in the order of 104 and 105 atoms/m, typically higher in the gaseous form with respect to the aerosol form. Also I in rainwater was measured, showing concentrations in the order of 10 atoms/L. The results show a very good agreement with the I profile, showing that, if background from other sources is not relevant, it is possible to estimate the impact of similar events years after them thanks to the sensitivity of techniques like Accelerator Mass Spectrometry.
