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, 2023
In 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 ...

Analysis of characteristics and validation of 6 MV photon beam produced by Elekta Synergy linear accelerator using EGSnrc Monte Carlo code

Radiation Physics and Chemistry, 2021
The most important step of the Monte Carlo (MC) dose calculation is the correct modelling of the radiation device. This study was aimed to determine the initial electron beam characteristics of the BEAMnrc model of 6 MV photon beam of Elekta Synergy IGRT

CSnrc: correlated sampling Monte Carlo calculations using EGSnrc.

Medical physics, 2004
CSnrc, a new user-code for the EGSnrc Monte Carlo system is described. This user-code improves the efficiency when calculating ratios of doses from similar geometries. It uses a correlated sampling variance reduction technique. CSnrc is developed from an existing EGSnrc user-code CAVRZnrc and improves upon the correlated sampling algorithm used in an ...

Simulation of phoswich detectors using MCNPX and EGSNRC

Radiation Protection Dosimetry, 2010
The in vivo monitoring Lab at KIT uses two phoswich detectors for routine lung counting. A simplified model of one of them has been implemented in the two Monte Carlo codes EGSnrc and MCNPX. The active part of the detector consists of a crystal of NaI(Tl) and one of CsI(Tl): the energy deposited in both the crystals have been studied to consider the ...
