Characterizing Subcritical Assemblies with Time of Flight Fixed by Energy Estimation Distributions
, 2018 We present the Time of Flight Fixed by Energy Estimation (TOFFEE) as a measure of the fission chain dynamics in subcritical assemblies. TOFFEE is the time between correlated gamma rays and neutrons, subtracted by the estimated travel time of the incident

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.

Introducing an Optimized Computing Method to Improve Parallel-Hole Collimators’ Response in Nuclear Medicine [PDF]
مجله علوم و فنون هستهای, 2019 Performance of parallel-hole collimators may be evaluated by determining their response to a point radioactive source which for instance, the amount of collimator resolution is calculated by measuring the full width at half maximum (FWHM) of point spread

Current status of MCNP6 as a simulation tool useful for space and accelerator applications
, 2012 For the past several years, a major effort has been undertaken at Los Alamos National Laboratory (LANL) to develop the transport code MCNP6, the latest LANL Monte-Carlo transport code representing a merger and improvement of MCNP5 and MCNPX. We emphasize

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.

Measurements of ultracold neutron upscattering and absorption in polyethylene and vanadium
, 2013 The study of neutron cross sections for elements used as efficient ``absorbers'' of ultracold neutrons (UCN) is crucial for many precision experiments in nuclear and particle physics, cosmology and gravity.

Calculation and measurement of Al prompt capture gammas above water in a pool-type reactor
Nuclear Engineering and Technology, 2022 Prompt capture gammas are an important part of the fission reactor gamma field. Because some of the structural materials after neutron capture can emit photons with high energies forming the dominant component of the gamma spectrum in the high energy ...

Investigation of the fundamental constants stability based on the reactor Oklo burn-up analysis
, 2010 The burn-up for SC56-1472 sample of the natural Oklo reactor zone 3 was calculated using the modern Monte Carlo codes. We reconstructed the neutron spectrum in the core by means of the isotope ratios: $^{147}$Sm/$^{148}$Sm and $^{176}$Lu/$^{175}$Lu ...
