Gamma-ray spectroscopy has been used for a wide range of environmental applications including sediment transport investigations and studies on contaminations arising from the nuclear industry. The basis of this technique is the measurement of gamma-ray emissions from primordial or anthropogenic radionuclides. Indeed, 210PB and 137Cs activities (with half-lives of 22.3 and 30.2 years, respectively), are usually applied to studies of sediment deposition in aquatic environments. Moreover, provided a low-background facility is available, this technique can be also used to trace tiny amount of uranium present in a solution. Therefore, we started a research program towards the identification of use of bacteria or fungal species in the biosorption of uranium from aqueous solutions.
