Q. What is alpha radiation?
Types of radiation there are three principal types of radiation are given off during radioactive decay. One kind is alpha radiation (α-radiation) which consists of alpha particles ejected from the nucleus. An alpha particle is equal to a helium-4 nucleus that is a nucleus with two protons and two neutrons. Alpha particles have a 2+ charge.
