First 129I Measurements at CologneAMS — •Christian Schlaier1, Stefan Heinze1, Martina Gwozdz1, Gereon Hackenberg1, Marco Michel2, Markus Schiffer1, Erik Strub2, and Dennis Mücher1 — 1Institut für Kernphysik, University zu Köln — 2Institut für Kernchemie, Universität zu Köln
In the Atacama Desert, one of the driest places in the world, plants had to adapt to survive with the low humidity mainly caused by fog. This fog contains an increased proportion of the unstable rare 129I due to nuclear bomb tests in the South Pacific. The AMS Iodine analysis of this plants can be used to gain information about environmental conditions and might help the colabborating bio- and geoscientists of the CRC1211 to understand the evolution of life in the hyper arid environement.
For this reason first Iodine measurements have been performed at the 6 MV AMS system of CologeneAMS. Standard samples covering the entire capabilities of the accelerator system were measured.
In this contribution we will present the current status and the results of the Iodine measurements in Cologne.
