Cherenkov radiation glowing in the core of the Advanced Test Reactor at Idaho National Laboratory. Cherenkov radiation (/ tʃ ə ˈ r ɛ ŋ k ɒ f / [1]) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of ...
Cherenkov radiation is not only present in the range of visible light or UV light but also in any frequency range where the emission condition can be met i.e. in the radiofrequency range. Different levels of information can be used. Binary information can be based on the absence or presence of detected Cherenkov radiation.
The emission of blue light is often attributed to Cherenkov radiation. [9] [verification needed] Cherenkov radiation is produced by charged particles which are traveling through a dielectric substance at a speed greater than the speed of light in that medium. Despite the production of similarity-colored light and an association with high-energy ...
This eerie blue light shows particles traveling faster than the speed of light.
Cherenkov radiation occurs when charged particles travel through a medium at a speed faster than the speed of light in that medium. High-energy gamma rays, upon striking the upper atmosphere, can create positron-electron pairs that move at great speeds. The residual effect of these particles traveling through the atmosphere can result in a ...
Hypotheses include Cherenkov radiation created as the cosmic ray particles pass through the vitreous humour of the astronauts' eyes, [4] [5] direct interaction with the optic nerve, [4] direct interaction with visual centres in the brain, [6] retinal receptor stimulation, [7] and a more general interaction of the retina with radiation.

Original – Cherenkov radiation, also known as Vavilov–Cherenkov radiation, is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.
A polar plot of the Cherenkov angles of photons associated with a 22 GeV/c particle in a radiator with =1.0005 is shown in Fig.2; both pion and kaon are illustrated; protons are below Cherenkov threshold, / >, producing no radiation in this case (which would also be a very clear signal of particle type = proton, since fluctuations in the number ...
