![]() 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. Cherenkov saw a faint bluish light around a radioactive preparation in water during experiments. ![]() Therefore, it is also known as Vavilov–Cherenkov radiation. The radiation is named after the Soviet scientist Pavel Cherenkov, the 1958 Nobel Prize winner, who was the first to detect it experimentally under the supervision of Sergey Vavilov at the Lebedev Institute in 1934. ![]() The phenomenon is named after Soviet physicist Pavel Cherenkov. Its cause is similar to the cause of a sonic boom, the sharp sound heard when faster-than-sound movement occurs. A classic example of Cherenkov radiation is the characteristic blue glow of an underwater nuclear reactor. ![]() ![]() Cherenkov radiation glowing in the core of the Advanced Test Reactor.Ĭherenkov radiation ( / tʃ ə ˈ r ɛ ŋ k ɒ f/ Russian: Эффект Вавилова–Черенкова, lit.'Vavilov–Cherenkov effect') 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 (speed of propagation of a wavefront in a medium) of light in that medium. ![]()
