Expanded and combined uncertainty in measurements by GM counters [PDF]

open access: yesNuclear Technology and Radiation Protection, 2007
This paper deals with possible ways of obtaining expanded and combined uncertainty in measurements for four types of GM counters with a same counter’s tube, in cases when the contributors of these uncertainties are cosmic background radiation and induced

The Microwave Background Radiation [PDF]

open access: yesSymposium - International Astronomical Union, 1990
We review the data on the spectrum and isotropy of the microwave background radiation and the astrophysical processes that may produce spectral distortions and anisotropies. As yet no fully satisfactory explanation has been found for the submillimeter excess observed by Matsumotoet al.(1988).

Adaptive Suppression Method of LiDAR Background Noise Based on Threshold Detection

open access: yesApplied Sciences, 2023
Background radiation in the LiDAR detection field of view is complex and variable, and the background noise generated can easily cause false alarms in the receiver, which affects the effective detection of the system.
