Measuring γ–ray dose of terrestrial samples using β-γ Spectrometry
Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
متن کاملX-ray Spectral Properties of γ-ray Bursts
We summarize the spectral characteristics of a sample of 22 bright γray bursts detected with the γ-ray burst sensors aboard the satellite Ginga. This instrument employed a proportional and scintillation counter to provide sensitivity to photons in the 2 400 keV range, providing a unique opportunity to characterize the largely unexplored X-ray properties of γ-ray bursts. The photon spectra of th...
متن کاملupper cretaceous in iran
between the lower and upper cretaceous there were some diastrophic movements, belonging to the austrain phase. these movements, which can be traced in many parts of north and central iran, caused extensive precenomanian erosion. even in southwest iran a wide spread discontinuity is reported at the base of the kazhdumi formation, which is possibly related to these movements. in the kopet - dagh ...
متن کاملSpectral energy distribution of the γ - ray microquasar LS 5039
The microquasar LS 5039 has recently been detected as a source of very high energy (VHE) γ-rays. This detection, that confirms the previously proposed association of LS 5039 with the EGRET source 3EG J1824−1514, makes of LS 5039 a special system with observational data covering nearly all the electromagnetic spectrum. In order to reproduce the observed spectrum of LS 5039, from radio to VHE γ-r...
متن کاملUpper Cretaceous Petroleum System of Northwestern Persian Gulf
Three well - known source rocks of the Zagros basin and the Persian Gulf are Mesozoic in age.The Jurassic Sargelu, Albian Kazhdumi and Neocomian-Coniacian Garau formations have charged the Cretaceous reservoirs of this area. The northwest part of the Persian Gulf is strongly influenced by two major N-S trending paleohighs (Hendijan- Bahregansar-Regesafid-Izeh and Kharge- Mish) and surrounding p...
