We're not going to go into details about the exact origins of alpha, beta and gamma radiation in this lesson. Animation giving an idea of the relative size and speed of alpha, beta and gamma radiation. For the moment we'll say that alpha and beta radiation consist of tiny particles, much smaller than an atom. They move incredibly fast, perhaps thousands of kilometres per second. Gamma radiation is a sort of invisible, very high-energy light. Alpha, beta and gamma are the first three letters of the Greek alphabet. The types of radiation are named in the order that they were discovered.
