Preparation and characterization of bismuth-filled high-density polyethylene composites for gamma-ray shielding

Radiation Protection and Environment, 2019
An attempt has been made to prepare the nonlead-based gamma shielding materials by adding different weight percentages (0%, 10%, 20%, and 40%) of bismuth in high-density polyethylene (HDPE) matrix.

Achieving full diversity in multi-antenna two-way relay networks via symbol-based physical-layer network coding [PDF]

, 2013
This paper considers physical-layer network coding (PNC) with M-ary phase-shift keying (MPSK) modulation in two-way relay channel (TWRC). A low complexity detection technique, termed symbol-based PNC (SPNC), is proposed for the relay.

Half-value layer measurement: simple process method using radiochromic film [PDF]

Australasian Physics & Engineering Sciences in Medicine, 2009
Although the half-value layer (HVL) is one of the important parameters for QA and QC, constant monitoring has not been performed because the measurements using an ionization chamber (IC) are time-consuming and complicated. To solve these problems, the use of radiochromic film (GAFCHROMIC XR TYPE R: GAF-R) with step-shaped aluminum (Al) filters ...

Effect of Waste Iron Filings (IF) on Radiation Shielding Feature of Polyepoxide Composites

Crystals, 2023
In the present work, photon and neutron attenuation properties of polyepoxide composites produced by doping waste iron filings (IF) at different percentages (0%, 20%, 40%, and 60% iron filing percentage) were obtained using theoretical and experimental ...

Methodology study for determining the half-value layer using the Monte Carlo code PHITS

Brazilian Journal of Radiation Sciences
For most purposes, the quality of a beam can be specified in terms of the half-value layer (HVL), which is the thickness of material required to reduce the air kerma  to half, at one meter from the source, from a unidirectional beam of infinitesimal ...

The onset of instability in unsteady boundary-layer separation

, 1996
The process of unsteady two-dimensional boundary-layer separation at high Reynolds number is considered. Solutions of the unsteady non-interactive boundary-layer equations are known to develop a generic separation singularity in regions where the ...
