MCNP: Multigroup/adjoint capabilities [PDF]

, 1994
This report discusses various aspects related to the use and validity of the general purpose Monte Carlo code MCNP for multigroup/adjoint calculations. The increased desire to perform comparisons between Monte Carlo and deterministic codes, along with the ever-present desire to increase the efficiency of large MCNP calculations has produced a greater ...

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

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
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 ...

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...
