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 کاملMicroquasars: hard X-ray/γ-ray emission
I review some of the basic observational details of jets from X-ray binaries, or ‘microquasars’. It is shown that in both (Z and Atoll) NS and BHC systems radio emission, and therefore jet formation, is correlated with the presence of hard (30–500 keV) X-ray emission. At γ-ray (> 500 keV) energies, the relation is not so clear. Possible physical connections between the presence of a jet, with a...
متن کاملAtmospheric Correction Inter-Comparison Exercise
The Atmospheric Correction Inter-comparison eXercise (ACIX) is an international initiative with the aim to analyse the Surface Reflectance (SR) products of various state-of-the-art atmospheric correction (AC) processors. The Aerosol Optical Thickness (AOT) and Water Vapour (WV) are also examined in ACIX as additional outputs of AC processing. In this paper, the general ACIX framework is discuss...

متن کاملX-ray and γ-ray observations of millisecond pulsars
The launch of several sensitive X-ray and γ-ray instruments during the last decade heralded a new era in the research of millisecond pulsars. The current number of millisecond pulsars detected in the X-ray spectral window is about 30, including those located in globular clusters, which represents a significant fraction of the total number of spin-down powered pulsars emitting high-energy radiat...
