Effect of TiO/VO substitution on the optical and radiation shielding properties of alkali borate glasses: A Monte Carlo investigation.

In this paper, we used Geant4 Monte Carlo simulations to investigate the effect of TiO/VO substitution on the radiation shielding properties of alkali borate glasses in the chemical form of 30LiO+55BO+5ZnO + xTiO+(10 - x)VO, where x = 0, 2.5, 5, 7.5, and 10 mol%.

Gamma-ray attenuation properties of some NLO materials: potential use in dosimetry.

Mass attenuation coefficients ([Formula: see text]) for some nonlinear optical materials such as potassium dihydrogen phosphate, ammonium dihydrogen phosphate, zinc tris-thiourea sulphate, and zinc thiourea chloride were measured using a [Formula: see text] NaI(Tl) scintillation detector at gamma energies of 122 keV, 356 keV, 511 keV, 662 keV, 840 keV, 1170 keV, 1270 keV, and 1330 keV. In addition, GEANT4 simulations were carried out to mimic the experiment at these energies. As a result, good agreement between the experimental and GEANT4 results was observed.
