Analysis of Transmitted Gamma-Rays by Multiple Scattering Method, (I)

Elastic scattering of 88.03-keV gamma rays.

Simulation of gamma-ray gamma rays by composite shields compared to the lead protection using the MCNPX code

In this study, cobalt 60 with a mean energy of (1.25 Mev) was used as a photonic source to investigate the effect of decreasing gamma-ray intensity by materials and polymer composite using MCNPX code. First, we investigated the effect of thickness and density on the reduction of gamma ray intensity, and then the comparison between the lead protector, tungsten and polymer composite in several th...

Anti-inflammatory role of piperine against rat lung tissue damage induced by gamma-rays

Background: Radiation‐induced acute lung damages are refractory side effects in lung cancer radiotherapy (RT). Prospective study investigates the possible role of piperine (Pip) as anti-inflammatory agent against γ-rays-induced lung tissue lesions in an applicable rat model. Materials and Methods: Fifty-six Sprague-Dawley rats were divided into four groups: Control, rats were administered...

Compton scattering of 662 keV gamma rays by aluminium and copper materials using NaI(Tl) detector

A rotating NaI(TI) scintillator detector and a collimated Cs 137 source producing gamma rays with an energy of 662 keV scattered incoherently by aluminum (Al) and copper (Cu) scatterers through the angles from 0 to 120° are used to study Compton scattering. The Compton scattering effect is investigated and found that the energy of scattered gamma ray decreases as the scattering angles increases...

HIGH LATITUDE GAMMA RAYS ASSOCIATED WITH VIRGO

A more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 GeV, obtained fromthe EGRET instrument at the Compton Gamma Ray Observatory. The derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with Virgo cluster (over lsr) and average Virgo intensity i...
