Simulation of vanadium-48 production using MCNPX code [PDF]

Nuclear Technology and Radiation Protection, 2012
Vanadium-48 was produced through the irradiation of the natural titanium target via the natTi(p, xn)48V reaction. The titanium target was irradiated at 1 mA current and by a 21 MeV proton beam for 4 hours. In this paper, the activity of 48V, 43Sc, and

MCNPX Model/Table Comparison [PDF]

, 2003
MCNPX is a Monte Carlo N-Particle radiation transport code extending the capabilities of MCNP4C. As with MCNP, MCNPX uses nuclear data tables to transport neutrons, photons, and electrons. Unlike MCNP, MCNPX also uses (1) nuclear data tables to transport protons; (2) physics models to transport 30 additional particle types (deuterons, tritons, alphas ...

Validation of MCNPX-PoliMi fission models [PDF]

2012 IEEE Nuclear Science Symposium and Medical Imaging Conference Record (NSS/MIC), 2012
We present new results on the measurement of correlated, outgoing neutrons from spontaneous fission events in a Cf-252 source. 16 EJ-309 liquid scintillation detectors are used to measure neutron-neutron correlations for various detector angles. Anisotropy in neutron emission is observed.

Low-energy neutron propagation in MCNPX and GEANT4 [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006
Simulations of neutron background from rock for underground experiments are presented. Neutron propagation through two types of rock, lead and hydrocarbon material is discussed. The results show a reasonably good agreement between GEANT4, MCNPX and GEANT3 in transporting low-energy neutrons.

Counterintuitive MCNPX results for scintillator surface roughness effect [PDF]

SPIE Proceedings, 2012
We performed a number of comparative MCNPX simulations of gamma energy depositions of scintillation crystals with smooth and rough surfaces. In the study, nine surface patterns (8 micro-roughness + 1 smooth) were coupled with eight common scintillation crystals for a total of 72 possible combinations.

MCNP/MCNPX model of the annular core research reactor. [PDF]

, 2006
Many experimenters at the Annular Core Research Reactor (ACRR) have a need to predict the neutron/gamma environment prior to testing. In some cases, the neutron/gamma environment is needed to understand the test results after the completion of an experiment.

A fast Monte Carlo code for proton transport in radiation therapy based on MCNPX

Journal of Medical Physics, 2014
An important requirement for proton therapy is a software for dose calculation. Monte Carlo is the most accurate method for dose calculation, but it is very slow. In this work, a method is developed to improve the speed of dose calculation. The method is

Systematic review of physical and dosimetric criteria for managing CIEDs in radiotherapy: A medical physicist's perspective. [PDF]

J Appl Clin Med Phys
Abstract Aim Current radiotherapy (RT) guidelines for Cardiac Implantable Electronic Devices (CIEDs) are largely based on clinical management strategies and retrospective reports. This systematic review adopts a medical physics perspective to provide a critical, quantitative analysis of the technical evidence required for developing robust safety ...
