Why do you see a blue glow inside of a reactor? | International Atomic Energy Agency (IAEA)

What’s that blue glow surrounding a reactor? It’s a phenomenon known as Cherenkov Radiation when electrically charged particles, such as protons or electrons, travel faster than light in a clear medium like water. | U.S. Department of Energy Office of Nuclear Energy

The Cherenkov effect, also known as Cherenkov radiation, is the emission of light when a charged particle travels through a dielectric medium at a speed greater than the speed of light in that medium. This phenomenon is analogous to a sonic boom, where a shockwave of sound is produced when an object surpasses the speed of sound. Follow @thatisnewton ,All credits to respective creators/owners.
