Alpha-like calculations with MCNP [PDF]

, 1997
Alpha (time-absorption eigenvalue) calculations are not an explicit calculational option in MCNP. Nevertheless, it is possible to perform alpha calculations with MCNP.

Investigation of inter‐source and intra‐source spectral variations in an electronic brachytherapy source using spectral measurements and Monte Carlo simulations

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background The Xoft electronic brachytherapy source is commonly used to treat superficial lesions and tumors located at shallow depths. However, uncertainties in material composition and geometry, mainly arising due to the manual assembly of the x‐ray tube components, contribute to inter‐source variability in the tube output spectrum.

Maxwell Spectrum as a Parameter to Verify the Dose in Brain Cancer (Glioblastoma) by Boron Neutron Capture Therapy (BNCT) using Monte Carlo Method

Brazilian Journal of Radiation Sciences
To evaluate the efficiency of neutron capture therapy (BNCT) treatment in glioblastoma multiforme, it is necessary to evaluate the impact of the neutron beam on the tumor cell and find better results so that BNCT treatment is viable.

بررسی تأثیر نوع آلیاژ آلومینیوم بکار رفته در دیواره اتاقک یونش چاهکدار مرتبط با هوای آزاد بر پاسخ اتاقک در انرژی پرتوهای گامای Cs137، Co57 و Am241 [PDF]

مجله علوم و فنون هسته‌ای, 2007
اتاقک‌های یونش چاهکدار مرتبط با هوای آزاد در مراکز پرتو درمانی برای اندازه‌گیری شدت چشمه‌های براکی تراپی به کار می‌روند. در این کار پژوهشی با استفاده از کد مونت کارلوی MCNP-4C، اتاقک یونش چاهکدار مدل HDR-33004 شبیه‌سازی شده است.

Mediating effect of social determinants of health between race and phthalate biomarkers in pregnancy

Pregnancy, Volume 2, Issue 1, January 2026.
Abstract Introduction Prenatal phthalate exposure is linked to adverse reproductive and developmental outcomes and is consistently higher among non‐Hispanic Black compared to non‐Hispanic White pregnant individuals, yet the factors responsible for these disparities are poorly characterized.
