Effect of zirconium oxide nanoparticles on thermal, optical, and radiation shielding properties of BiO-BO-MnO glasses.

This study has explored the DSC, UV-Vis absorption spectroscopy, gamma ray and neutron shielding properties of BiO-BO-MnO: ZrO glasses. It demonstrates a unique approach to photon shielding analysis using JENDL/PD-2016 photonuclear data and employs a validated spherical neutron model for neutron shielding. Five transparent glasses were prepared with the chemical composition (in mol%) of 29BiO-70BO-(1-x)MnO: xZrO, and labeled as MZ (for x = 0), MZ (for x = 0.

Evaluation of the Radiation Shielding Characteristics of Several Glass Systems Using the EPICS2017 Library.

In this paper, the investigation of the Electron-Photon Interaction Cross Sections 2017 (EPICS2017) library on the shielding characteristics of several glasses under various chemical systems is presented. The EPICS2017 library of ENDF/B-VIII was interpolated to calculate the mass attenuation coefficients (MACs) of selected glass systems. Results from EPICS2017 have been compared with values from experimental and theoretical methods used to evaluate the photon shielding properties.

Validation of an indium-based multi-shell neutron spectrometer.

A multi-shell neutron spectrometer with indium foil detector (In-MuNS) was developed to evaluate intense neutron fields that are generated in medical accelerators. The response matrix of this new spectrometer was calculated from 1 meV to 100 MeV using MCNP5 v.1.

Evaluation of time-dependent strengths of californium neutron sources by decay of Cf, Cf, and Cm: Uncertainties by Monte Carlo method.

A method for estimating source strength measurements of californium neutron sources is presented, based on the model of Cf, Cf, and Cm decay. This is combined with the Monte Carlo method (MCM) of propagating uncertainties. Californium sources were categorized into two types: Sort-A are those with most input quantities known while Sort-B are sources with only the mass at a certain reference date known.
