An intercomparison of microdosimetric and nanodosimetric quantities simulated Monte Carlo codes is in progress with the goal assessing uncertainty contribution to results due uncertainties electron interaction cross-sections used codes. In first stage intercomparison, significant discrepancies were found for as well simulations a radiation source placed at surface spherical water scoring volume...

Introduction: We describe a nephron-based dosimetry model for renal toxicity for radiopharmaceutical therapy suited to the nonuniform activity distribution of radiopharmaceutical. In radiopharmaceutical therapy, renal toxicity is observed while whole-kidney and renal cortex absorbed dose values are below toxicity thresholds established by external beam and targeted radiope ptid...
