Estimation of gamma radiation shielding qualification of newly developed glasses by using WinXCOM and MCNPX code

Progress in Nuclear Energy, 2019
In this study, the gamma photons shielding parameters of the newly produced (NG1, NG2, NG3 and NG4) and widely used (Window, PbO, Soda and Borosilicate glasses) glass samples were evaluated comparatively.

Coupling the SAND-II and MCNPX codes for neutron spectrum unfolding

Journal of Instrumentation, 2018
Measurement of neutron energy spectrum is very important to develop the application of neutrons in different fields of science and technology. One of the commonly used methods to measure the neutron energy spectrum is the threshold foil activation method and using an unfolding code such as SAND-II. The main limitation of such codes is that the geometry

Secondary neutron source modelling using MCNPX and ALEPH codes

SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo, 2014
Monitoring the subcritical state and divergence of reactors requires the presence of neutron sources. But mainly secondary neutrons from these sources feed the ex-core detectors (SRD, Source Range Detector) whose counting rate is correlated with the level of the subcriticality of reactor.

Proton Therapy of eye using MCNPX code

2018
Introduction: Proton radiotherapy is the one of advanced teletherapy methods. The protons deposit their maximum energy in a position called Bragg peak. Therefore, for treatment of cancer, the tumor should be placed at the Bragg peak or SOBP. The scattered photons and neutrons is a challenge in proton radiotherapy.

Shielding evaluation for solar particle events using MCNPX, PHITS and OLTARIS codes

Life Sciences in Space Research, 2015
Detailed analyses of Solar Particle Events (SPE) were performed to calculate primary and secondary particle spectra behind aluminum, at various thicknesses in water. The simulations were based on Monte Carlo (MC) radiation transport codes, MCNPX 2.7.0 and PHITS 2.64, and the space radiation analysis website called OLTARIS (On-Line Tool for the ...

Responses of a 6LiI Bonner Sphere Spectrometer using the Monte Carlo codes PHITS and MCNPX

Applied Radiation and Isotopes, 2023
The response functions (RFs) of a Bonner Sphere Spectrometer (BSS) with a 6LiI thermal neutron detector were calculated using the Monte Carlo codes PHITS (version 3.26) and MCNPX (version 2.7.0), with their own default nuclear data libraries, and physics models.

Spread‐out Bragg peak and monitor units calculation with the Monte Carlo Code MCNPX

Medical Physics, 2007
The aim of this work was to study the dosimetric potential of the Monte Carlo code MCNPX applied to the protontherapy field. For series of clinical configurations a comparison between simulated and experimental data was carried out, using the proton beam line of the MEDICYC isochronous cyclotron installed in the Centre Antoine Lacassagne in Nice.

Methodology for digital radiography simulation using the Monte Carlo code MCNPX for industrial applications

Applied Radiation and Isotopes, 2008
This work presents a methodology for digital radiography simulation for industrial applications using the MCNPX radiography tally. In order to perform the simulation, the energy-dependent response of a BaFBr imaging plate detector was modeled and introduced in the MCNPX radiography tally input. In addition, a post-processing program was used to convert

A new application of radioactive particle tracking using MCNPX code and artificial neural network

Applied Radiation and Isotopes, 2019
Stirrers and mixers are highly used in chemical, food, pharmaceutical, cosmetic, concrete industries and others. During the fabrication process, the equipment may fail to appropriately stir or mix the solution. Besides that, it is also important to determine when the right homogeneity of the mixture is attained.
