Re-evaluation of F-FDG absorbed and effective dose in adult and pediatric phantoms using DoseCalcs Monte Carlo platform: a validation study.

Positron emission tomography (PET) using F-FDG is a well-known modality for the diagnosis of various diseases in patients of different ages, sexes, and states of health, which implies that internal radiation dosimetry is highly desired for different phantom anatomies. In this study, we validate "DoseCalcs," a new Monte Carlo platform that combines personalized internal dosimetry calculations with Monte Carlo simulations. To achieve that, we used the specific absorbed fraction (SAF) calculated by DoseCalcs and those from ICRP publication 133 to estimate the absorbed dose per injected activity (AD/IA) and effective dose per injected activity (ED/IA) for F-FDG.

GUI development for SSDL to calibrate photon measuring equipment.

Current legislation mandates the inspection and calibration of operational survey radiation monitoring instruments used in nuclear medicine, radiotherapy departments, and other fields utilizing ionizing radiation sources. To comply with national and international radiation protection standards, Morocco's National Secondary Standard Dosimetry Laboratory provides reliable calibration results with high accuracy and covers various measurement ranges using attenuators provided by the automated Gamma G10 irradiator or validated beam qualities produced by the X-ray irradiator type X80-320 kV. This study aims to develop a digital graphical user interface using Python programming language, designed for calibrating radiation protection measuring instruments .

Specific absorbed fractions of electrons and photons for Digimouse voxelized phantom using GATE/GEANT4 Monte-Carlo simulation.

Knowledge of SAF at different energies is crucial for internal dosimetry. For this purpose, a set of calculated SAF values for a mouse voxelized phantom's selected organs are presented below. Values of SAF were calculated for mono-energetic photons and electrons with energy varying from 10 keV to 4 MeV using the Monte Carlo simulation via GATE/GEANT4 code (GEANT4 Application for Emission Tomography).
