AB:
During the Campaign MILAGRO, several filters of Teflon were collected in site T1 (TECAMAC), using the PQ200
sampler of 2.5 micrometer fine particles and measured by means of HPGe nuclear detector at the Research
Center for Advanced Materials SC (CIMAV). The objective of the present work is to determine by means of the
multivariate analysis, if the isotopic contents of the aerosols (238U, 232Th and 40K) are dependant or not form
the originating plume of the metropolitan zone of the Mexico Valley (ZMVM). The results of the research indicate
that there isn't a high correlation between the specific activities of the natural isotopes in the study with
the wind direction or its strength. Therefore, the conclusion is that the natural radioactive contents of the
particulate matter in air are a complete local dependency.
