Web12 aug. 2024 · Ionizing radiation is divided into four different types: alpha, beta, gamma, and x-ray radiation. Each type of radiation can be blocked, or shielded, by different materials. This activity uses common classroom materials to help illustrate the differences between each type of radiation. This activity is intended for middle and high school students. WebThe four forms of ionizing radiation are alpha particles, beta particles, gamma rays, and, indirectly, neutrons. All have enough energy to ionize atoms, in other words, remove one or more of the atom’s electrons. An alpha particle consists of two protons and two neutrons, the equivalent of the nucleus of a helium atom.
