The Geant4 physics lists package encompasses predefined selections of physics processes and models to be used in simulation applications. Limited documentation is available in the literature about Geant4 pre-packaged PhysicsLists and their validation. The reports in the literature mainly concern specific use cases. This paper documents the epistemological grounds for the validation of Geant4 pr...
In this study, the protection parameters of gamma-ray Borate glass system containing 10Li2O. 10K2O. 20Na2O. xPbO. (60-x) B2O3 where x to be varied as 0, 10, 20, 30, 40, 50 and 60, were investigated using Monte Carlo simulation code Geant4. The coefficients attenuation calculated Geant4 a function incident photon 0.0015 MeV 15 MeV. accuracy simulated results was tested by XCOM program. showed re...
End users run GEANT4 executable les customized and provided by application programmers. GAG (GEANT4 Adaptive GUI) is a GUI for them to run GEANT4 by using commands and by changing associated parameters. We have two implementations of GAG, that is, Tcl/Tk and Java versions. GAG provides them with a tree (Java) or Pull-down menu (Tcl/Tk) of commands, a widget of parameter inputs of variable forma...
Today, targeted radiation therapy (TRT) methods for cancer treatment, besides the goal of completely destroying the target tumor, attempts to prevent nearby healthy cells from exposure to ionizing radiation as far as possible. Hence, short-range charged particles, such as low-energy electrons that are suited to achieving these two goals together, play an important role in TRT and so, adoption o...
Geant4 is a versatile Monte Carlo radiation transport simulation toolkit with steep learning curve. This work introduces user-code called M-TAG (Modular Radiation Teaching-Aid for Geant4), built on top of Geant4. designed to help gradually introduce the new users.The goal record quantities from simulated as it transported through geometries. simplifies inclusion geometric elements and detector ...
The aim of this study is to investigate the gamma ray radiation absorption properties bismuth oxide (Bi2O3), and determine effect lead (PbO) additive in shielding Bi2O3. For reason, parameters such as mass attenuation coefficient (MAC), linear (LAC), half value layer (HVL), tenth (TVL) mean free path (mfp) were calculated theoretically for Bi2O3, PbO, 50% Bi2O3-50%PbO. all results obtained by u...
The present paper describes the new, original implementation of a point-wise neutron treatment that is made available with FLUKA v4.3-0 ( https://fluka.cern ). development based on pre-processed data libraries for Geant4 code https://cern.ch/geant4 was written from scratch in C++ and able to load information all databases (ENDF, JEFF, JENDL, CENDL, BROND), including materials S(α,β,T) nuclear b...
The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this paper, we benchmark two contemporary codes, DIMAD and BDSIM, the latter being a relatively new tracking code built within the framework of GEANT4. We consider both the 20 mrad and 2 mrad extraction lines of the 500 GeV International Linear Collider (ILC) and we ...

Measurement of the helicity dependent elastic electron-proton scattering cross section provides a key means investigating parity violation within proton. However, such measurements exhibit potential instrumental effects associated with detection polarized recoiled protons. In particular, spin-orbit interactions massive detector induce systematic spatial shift in signal. this study, we determine...
