Altzomoni (Mexico) is located in the Izta-Popo Zoquiapan National Park, between the Iztaccihuatl (5286 m a.s.l) and Popocatepetl (5462 m a.s.l) volcanoes. Altzomoni is approximately 60 km away from Mexico City.
In this work, the radiochemical procedure for the measure of 10Be in small rainfall samples was established. 10Be concentrations were determined in rainfall collections during the rainy seasons of 2017and 2018. The 10Be concentrations of annual rainfall collections for the period of sampling range from 1.91 x 107 to 5.44 x 107 atoms L-1, and the corresponding fallout values were between 1.9 x 105 and 9.8 x 105 atoms cm-2 y-1 which are significantly lower than those reported in the Southern Alps mountain (9-19 x 106 atoms cm-2 y-1).
Dr. Méndez, obtained her degree in Chemical Engineering from the Instituto Tecnológico de México in 2006. She did a master’s degree in Environmental Science and Technology in 2009 and in 2014 obtained her doctorate in Materials Science at the Research Center in Advanced Materials.
Currently, she holds the position of Conacyt Chair at the Physics Institute of the National Autonomous University of Mexico, developing research on cosmogenic isotopes using accelerator mass spectrometry.
