Around the core of a nuclear reactor shielded by a large pool of water, Cerenkov radiation appears as a blue glow (see figure below). Cerenkov radiation occurs when a particle travels faster through a
medium than the speed of light in that medium. It is the electromagnetic equivalent of a bow wave or a sonic boom. An electron is traveling through water at a speed 7.2% faster than the speed of
light in water.
