X‐ray and γ‐ray Sensing from Aqueous‐Based Lead Sulfide Telluride Nanocomposites

Small, Volume 21, Issue 49, December 10, 2025.
PbSxTey nanoparticles integrate into flexible, size‐scalable aramid polymeric scaffolds, forming percolation paths capable of efficiently transporting the electrons and holes created by penetrating photonic interactions. The resulting nanosemiconductor‐nanofiber composite forms the basis for room‐temperature spectroscopic sensors of X‐rays and γ‐rays ...

Validation and Application of MCNP and TORT Source Generation Codes

Energy Procedia, 2017
Abstract Primary Shielding Calculation (PSC) plays an important role in reactor shielding design and analysis. In order to facilitate PSC, a source generation code is developed to generate cumulative distribution functions (CDF) for the source particle sample code of the MCNP code, and a source particle sample code is developed to sample source ...

Correlation Patterns of Muon Flux With Vertical Atmospheric Profiles: Insights From Monte Carlo Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

A Monte-Carlo Benchmark of TRIPOLI-4® and MCNP on ITER neutronics

EPJ Web of Conferences, 2017
Radiation protection and shielding studies are often based on the extensive use of 3D Monte-Carlo neutron and photon transport simulations. ITER organization hence recommends the use of MCNP-5 code (version 1.60), in association with the FENDL-2.1 ...

131I-Chlorotoxin dosimetry in liver using MCNP simulation code

Archives of Advances in Biosciences, 2013
     Chlorotoxin is a 36 amino acids peptide, which is able to block chloride channels isolated from mouse brain. A derivative of chlorotoxin is synthesized and it is labeled by iodine 131; then animal experiments carry out on rats. Multiple organ doses may be calculated with biological distribution results in rats with labeled compounds using ...

Iterative Determination of Distributions by the Monte Carlo Method in Problems with an External Source

, 2013
In the Monte Carlo (MC) method statistical noise is usually present. Statistical noise may become dominant in the calculation of a distribution, usually by iteration, but is less Important in calculating integrals.

A comparative study of clinically used fast Monte Carlo dose engines for proton therapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Background Several fast Monte Carlo (MC) codes have been implemented and used to simulate proton transport and calculate patient doses in proton therapy. The resulting dose is typically compared to full MC codes, rather than other fast MC codes.
