GEOCHEMISTRY AND ENVIROMENTAL RADIOACTIVITY RNM929

Description

The Research Group on Geochemistry and Environmental Radioactivity (GyRA) is a multidisciplinary group whose activity is focused on the study of chemical and transport processes related to the atmospheric composition. These processes, in turn, have linkage and influence on other components within terrestrial and aquatic environments. Group members have extensive experience in the environmental analysis of trace elements, stable isotopes, and radioisotopes for use as tracers of environmental processes.

Research Topics

Geochemistry of aerosols and the atmospheric deposition.
Use of stable isotopes and natural and man-made radionuclides as tracers of environmental processes.
Influence of atmospheric deposition on the geochemical characteristics of coastal surface waters.
Geochemical dynamics of N, P and Si in marine ecosystems.
Development of radiometric methods for the measurement of low-level radionuclide concentrations.
