Radiological modeling in the environment: application and adaptation of ionising radiation dosimetry models in the Mediterranean terrestrial ecosystem

Abstract

The present study deals with the quantification of radionuclides' transfer in the terrestrial environment and with the estimation of the subsequent radiological exposure of non-human organisms. In order to describe the behavior of radionuclides in the environment, a dose assessment software was used. The ERICA Assessment Tool was applied and adapted to the peculiarities of a simple food chain, representative of the terrestrial Mediterranean ecosystem. The followed methodology consisted of site-specific sampling of abiotic material (soil) and organisms (vegetation and mammals). The selected samples were properly treated, in order to obtain the appropriate geometry, and afterwards measured with gamma spectrometry using HPGe detectors. After the determination of radionuclides' content, the simulations were conducted. The obtained results give an insight of the levels of the radioecological parameters that were calculated based on the studied ecosystem features. The Concentration Ratio is ...
