a Numerical solution of the Boltzmann transport equation . b Monte Carlo simulation using Geant4 code .
from to the data provided by the ICRP 144 report using the same voxel phantoms are in good agreement with the present work . Despite discrepancies in organ DCFs , effective dose estimates for human exposure to soil radioactivity agree with literature values , highlighting the need for further detailed research on organ absorbed DCFs . This study is the initial step in a broader program aimed at enhancing predictions of human exposure to contaminated soils from radioactive waste . Future work includes benchmarking simulation exercises to test the model under various scenarios .
