What is Cherenkov radiation used for?
In particle physics, the Cherenkov radiation is used frequently in particle identification detectors (PID). Particle identification plays a crucial role in particle physics to separate particles such as protons, electrons, muons, pions, etc at different velocities.
Why did Chernobyl glow blue?
Caused by particles traveling faster than light through a medium, Cherenkov Radiation is what gives nuclear reactors their eerie blue glow. In the miniseries “Chernobyl” when the reactor first explodes, there’s an eerie blue light emanating from it.

How fast is Cherenkov radiation?
The Cherenkov radiation in cases such as this is caused by electrons from the reactor traveling at speeds greater than the speed of light in water, which is 75 percent of the speed of light in a vacuum. The energetic charged particle traveling through the medium displaces electrons in some of the atoms along its path.
What does Cherenkov radiation look like?
Cherenkov radiation, when it is intense, appears as a weak bluish white glow in the pools of water shielding some nuclear reactors.
What is Cherenkov radiation?
Cherenkov radiation results when a charged particle, most commonly an electron, travels through a dielectric (can be polarized electrically) medium with a speed greater than light’s speed in that medium. A common analogy is the sonic boom of a supersonic aircraft.
What is the Cherenkov Telescope Array?
Cherenkov Telescope Array. The Cherenkov Telescope Array or CTA is a multinational, worldwide project to build a new generation ground-based gamma-ray instrument in the energy range extending from some tens of GeV to about 300 TeV.
What is the Cherenkov angle at the threshold velocity?
The Cherenkov angle is zero at the threshold velocity for the emission of Cherenkov radiation. The angle takes on a maximum as the particle speed approaches the speed of light. Hence, observed angles of incidence can be used to compute the direction and speed of a Cherenkov radiation-producing charge.
What did Cherenkov see in his experiment?
Cherenkov saw a faint bluish light around a radioactive preparation in water during experiments. His doctorate thesis was on luminescence of uranium salt solutions that were excited by gamma rays instead of less energetic visible light, as done commonly.
