A review of medical diagnostic imaging methods utilizing x-rays or gamma rays and the application and development of inorganic scintillators is presented.

We review recent progress in elucidating the relationship between high-energy radiation and interstellar medium (ISM) young supernova remnants (SNRs) with ages of $\sim$2000 yr, focusing particular on RX J1713.7$-$3946 RCW 86. Both SNRs emit strong nonthermal X-rays TeV $\gamma$-rays, they contain clumpy distributions gas that includes both atomic molecular hydrogen. find shock-cloud interactio...

We use the GALPROP model for cosmic-ray propagation to obtain a new estimate of the Galactic component of gamma rays, and show that away from the Galactic plane it gives an accurate prediction of the observed EGRET intensities in the energy range 30 MeV – 50 GeV. On this basis we reevaluate the extragalactic gamma-ray background. We find that for some energies previous work underestimated the G...

Mutation breeding is one of the breeding methods used successfully in durum wheat for selecting lines with increased agronomic values. This study was carried out to determine gamma rays effect and interaction between gamma-rays and the genotype of treated variety of winter wheat in mutations induction. We used physical mutagens: gamma-rays in doses 100, 150, 200, 250 Gy. Seeds of eight winter w...
