Fuel burnup analysis for Thai research reactor by using MCNPX computer code [PDF]
Journal of Physics: Conference Series, 2017 This paper presents the fuel burnup analysis of the Thai research reactor (TRR-1/M1), TRIGA Mark-III, operated by Thailand Institute of Nuclear Technology (TINT) in Bangkok, Thailand. The modelling software used in this analysis is MCNPX (MCNP eXtended) version 2.6.0, a Fortran90 Monte Carlo radiation transport computer code.

Characterization of the light and flexible nonlead aprons as an alternative to Pb–PVC
Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Background Radiation shielding is crucial for protecting healthcare professionals from scatter radiation during x‐ray procedures. Conventional lead aprons, although effective, are limited by their high weight, low flexibility, and potential toxicity.

Simulation of surface flux received through breast tumor radiation therapy with MCNPX code
International Journal of Biophotonics and Biomedical Engineering, 2023 In radiation therapy, investigating of the effects of the surface flux reaching on the tissue is important in planning the treatment and this requires a precise evaluation of the absorbed dose distribution throughout the irradiated tissue. Therefore, by Monte Carlo simulation with MCNP code, a point source with the size of E with a spectrum width of 0 ...
