Résumé : |
The simulated HPGe-source detector was then used for the determination of the activity concentrations of 226Ra, 232Th, 40K, and 137Cs for artichoke, fennel, mustard, bean, mushroom, onion and garlic crops with their corresponding soils, harvested from different agricultural areas in Algeria. The transfer factors of those radionuclides were evaluated using the activity concentration of each radionuclide in the soil and crop sample. The determination of TFs provides a preliminary data of the radioactivity level in the studied areas, and it serves as an initial measurement that can be used as a starting point for further investigation or monitoring. The transfer of 137Cs from soil to crops were determined in order to validate and correct the existed soil erosion models. The study found that there was no significant transfer under consideration.
Therefore, the simulated model with the measuring geometry is suitable and reliable enough for the purpose of determining the activity concentrations of soil and plant environmental samples, taking into account the self-absorption and coincidence summing effect corrections.
To enhance our understanding of radionuclide transfer from soil to crops in Algeria, adopting a larger perspective by including a wide variety of crops. This will yield a more robust dataset, for making well informed decisions to safeguard the environment and human health.
