Electromagnetic Shielding of Metal Enclosures with Apertures
operating voltages. Among the electromagnetic compatibility (EMC) topics, shielding is a prominent one and there is a burgeoning trend to study its different aspects. The inevitable need for the air ventilations, input/outputs and other means of connections...
Characterization of a new shielding rubber for use in neutron–gamma mixed fields
A variety of formulations was investigated for the fabrication of an appropriate shielding rubber to be used in neutron–gamma mixed fields. Having considered the required mechanical properties together with tungsten as the gamma-ray absorbing...
Synthesis, characterization and UV-shielding performance of TiO2/SiO2 Nanofibers
characterized by X-Ray Diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis techniques. The influence of different amount of TiO2 and SiO2 nanoparticles (NPs) on UV-shielding performance of TiO2/SiO2 nanofibers was investigated...
An optimal approach for smart grid economic dispatch
Electromagnetic interference (EMI) shielding of ordered mesoporous carbon (OMC)/paraffin composites
A quality survey on different shielding configurations of gamma ray detector used with a portable PGNAA system
The appropriate gamma-ray detector shielding configuration is critical for a precise prompt gamma neutron activation analysis (PGNAA) measurement. The shielding material has to prevent the radiation damage to the detector crystal and it must produce...
Improving the Shielding Effectiveness of a Rectangular Metallic Enclosure with aperture by Using Extra Shielding Wall
A new method for improving shielding effectiveness (SE)
of a rectangular enclosure with multiple apertures has been proposed.
In this method in order to compensate the effects of the apertures
on reduction of (SE) parameter...
Shielding Effectiveness Measurement for Extremely Small Dimension Enclosures
In this paper, practical aspects of a newly proposed method based on the aperture impedance for estimation and measurement of the shielding effectiveness (SE) of enclosures will be discussed in more details. A special de-embedding procedure...
Increasing the Personnel Safety of a Landmine Detection System using Proper Shielding Materials
investigated
different thicknesses of proper neutron shielding materials
such as polyethylene and boric acid around the system to shield neutrons
and increase the safety conditions for the operators. The effect
of using different...
The Effects of Breasts Shielding on Dose Reduction in CT Examinations
enough to be a matter of concern. Therefore, the purpose of our study was to measure breasts dose during chest CT with and without bismuth and lead shielding.
In this study, the amount of dose reduction achievable by shielding the breast tissues...
