Optical simulation and experimental measurement of gamma ray energy spectrum of plastic scintillators with different sizes

The application of large plastic scintillators is widely increasing in the different areas of industry, medicine and security due to technical and economic advantages. One of the main disadvantages of these detectors is the unknown position of Compton edge at gamma ray spectrum. In this research, GEANT4/GATE code has been used to simulate the gamma ray spectrum for different volumes of large pl...

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...

The Energy of Gamma-Ray Bursts

The energy of a Gamma-Ray Burst is one of the most interesting factors that can help determining the origin of these mysterious explosions. After the discovery that GRBs are cosmological it was thought, for a while that they are standard candles releasing ∼ 1051ergs. Redshift measurements that followed the discovery of GRB afterglow revealed that GRBs are (i) further than what was initially bel...
