The MCNPX Monte Carlo Radiation Transport Code

open access: yesAIP Conference Proceedings, 2007
MCNPX (Monte Carlo N‐Particle eXtended) is a general‐purpose Monte Carlo radiation transport code with three‐dimensional geometry and continuous‐energy transport of 34 particles and light ions. It contains flexible source and tally options, interactive graphics, and support for both sequential and multi‐processing computer platforms.

Linear Boltzmann equation solver for voxel‐level dosimetry in radiopharmaceutical therapy: Comparison with Monte Carlo and kernel convolution

open access: yesMedical Physics, Volume 51, Issue 8, Page 5604-5617, August 2024.
Abstract Background With recent interest in patient‐specific dosimetry for radiopharmaceutical therapy (RPT) and selective internal radiation therapy (SIRT), an increasing number of voxel‐based algorithms are being evaluated. Monte Carlo (MC) radiation transport, generally considered to be the most accurate among different methods for voxel‐level ...

Characterizing the voxel‐based approaches in radioembolization dosimetry with reDoseMC

open access: yesMedical Physics, Volume 51, Issue 6, Page 4007-4027, June 2024.
Abstract Background Yttrium‐90 (90Y$^{90}{\rm {Y}}$) represents the primary radioisotope used in radioembolization procedures, while holmium‐166 (166Ho$^{166}{\rm {Ho}}$) is hypothesized to serve as a viable substitute for 90Y$^{90}{\rm {Y}}$ due to its comparable therapeutic potential and improved quantitative imaging.

Neutronic Analysis of Accident‐Tolerant Cladding Materials in 3D Full Core BEAVRS PWR Benchmark Using OpenMC Code

open access: yesInternational Journal of Energy Research, Volume 2024, Issue 1, 2024.
After the Fukushima Daiichi nuclear accident in 2011, the performance of nuclear fuel during accidents became a matter of great concern. To address this, a new type of fuel technology called accident‐tolerant fuel (ATF) has been developed with the goal of enhancing the ability of light water reactors (LWRs) to withstand severe accident conditions.
