Intergalactic UV background radiation field [PDF]
Journal of Astrophysics and Astronomy, 1997 We have performed proximity effect analysis of low and high resolution data, considering detailed frequency and redshift dependence of the AGN spectra processed through galactic and intergalactic material. We show that such a background flux, calculated using the observed distribution of AGNs, falls short of the value required by the proximity effect ...

Journal of Air Pollution and Health, 2017 Introduction: Gamma ray radiation can cause ionization and harmful effects on human health due to its high levels of energy. However, contrary to popular belief, natural sources of gamma radiation are far greater in number than artificial sources.

Quantum limitations of distant radiating objects detection
Физика волновых процессов и радиотехнические системы, 2014 Weak electromagnetic signals from sufficiently distant sources reveal quantum properties. The latter ones result that detection of the sources becomes probabilistic.

RADIATION SAFETY OF BULGARIA IN THE CONTEMPORARY INTERNATIONAL SITUATION
Security and Defence Quarterly, 2016 It is known that everything on our planet is subjected to constant exposure from the natural and anthropogenic, earth and space SIR, and is situated in conditions created by natural and technical radioactive Backlight.

Entropy-Based Characterization of Internet Background Radiation
Entropy, 2014 Network security requires real-time monitoring of network traffic in order to detect new and unexpected attacks. Attack detection methods based on deep packet inspection are time consuming and costly, due to their high computational demands.

Below-Background Ionizing Radiation as an Environmental Cue for Bacteria
Frontiers in Microbiology, 2017 All organisms on earth grow under the influence of a natural and relatively constant dose of ionizing radiation referred to as background radiation, and so cells have different mechanisms to prevent the accumulation of damage caused by its different ...
