Determinación de radionucleidos naturales y artificiales en la zona alta de la Provincia de Chimborazo

Abstract

The province of Chimborazo, located in a volcanic region and nestled between two mountain ranges, faces uncertainties about the presence and distribution of radionuclides in its highlands, with possible consequences for health and the environment. The objective of the study was to determine the concentration of natural and artificial radionuclides in the soil of the highlands of Chimborazo province. Gamma spectrometry was employed in a stratified sampling design, randomly assigning points in two mountain ranges and adopting a quantitative and experimental approach. The results revealed remarkable concentrations, especially for 226Ra, averaging 157.2 Bq/kg, significantly higher than the global average. 232Th showed concentrations within the international range, while 40K exhibited slightly lower levels. Point RAN39-05 stood out with exceptional concentrations, especially for 226Ra and 232Th. In addition, the analysis of terrestrial gamma radiation identified three zones with different intensities, all exceeding the global average. The variability in concentrations and radiation levels suggests geological and environmental complexity that influences the distribution of radionuclides in the area. In conclusion, continuous monitoring and considerations in land use planning are recommended to mitigate potential environmental risks and protect the population's health in the upper Chimborazo zone. This study contributes to the understanding of radiation in the region and highlights the importance of future research to address potential environmental and health implications.
