The EGSnrc System, a Status Report
2001EGSnrc [1] is a general-purpose package for the Monte Carlo simulation of coupled electron-photon transport that is based on the popular EGS4 system but incorporates a variety of improvements in the class II implementation of the condensed history technique and the modelling of the underlying physical processes.

Cross section improvements for EGSnrc
Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002The inclusion of spin effects for electron/positron elastic scattering, binding effects for incoherent photon scattering and atomic relaxations into EGSnrc is described. The effects of these improvements on calculated depth-dose curves and plane-parallel chamber calculations is presented.

Gamma ray shielding properties of synthesized lanthanide borides using EGSnrc code
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2023In this study, we have investigated some hexaborides which are synthesized for the purpose of gamma-ray shielding. These materials were synthesized by the method of magnesiothermic reduction process in the open air, and stoichiometric amounts of M2O3, B2O3, and Mg (20% excess) were mixed where MIII is a three oxidation state lanthanide metal (DyIII ...

EGSnrc calculation of activity calibration factors for the Vinten ionization chamber
Applied Radiation and Isotopes, 2018The National Physical Laboratory Vinten 671 chamber was selected as a proving ground for a new radionuclide source model in the EGSnrc software. The computational Vinten model is validated against measurements of radionuclide artifacts whose activities were determined by absolute methods.

Comparison between EGSnrc, Geant4, MCNP5 and Penelope for mono-energetic electron beams
Physics in Medicine and Biology, 2015A simple geometry is chosen to highlight similarities and differences of current electron transport algorithms implemented in four Monte Carlo codes commonly used in radiation physics. Energy deposited in a water-filled sphere by mono-energetic electron beams was calculated using EGSnrc, Geant4, MCNP5 and Penelope as the radius of the sphere varied ...

Optimization of dual electron multileaf collimator materials by use of EGSnrc
Radiological Physics and Technology, 2010A dual electron multileaf collimator (eMLC) has recently been proposed and ascertained to be effective in the collimation of therapy electron beams. The EGSnrc Monte Carlo code has been used in the optimization of the dual eMLC by simulation of the Varian 2100C medical linear accelerator with the applicator completely replaced by the dual eMLC, and ...

Monte Carlo simulation of backscatter from lead for clinical electron beams using EGSnrc
Medical Physics, 2008In electron radiotherapy of superficial lesions in the eyelid, lip, buccal mucosa, ear, and nose, backscattered electrons are produced from the lead shield used to protect the critical tissue underneath the tumor. In this study, the backscattered electrons, produced by clinical electron beams using a Varian 21 EX linear accelerator, were studied using ...
