👉 Cherenkov radiation is a type of radiation that originates from charged particles, such as electrons or protons. It is characterized by its high energy and its ability to scatter off other types of matter, including electrons and photons. The phenomenon was first observed in 1953 by the physicist Eugene Cherenkov, who used it to determine the masses of certain elements. Cherenkov radiation can be detected using a special type of detector called a cherenkov counter or a cherenkov
