Question

Quizplus · Accepted Answer

Gamma radiation is the most penetrating of the types listed. Unlike alpha and beta radiation, which consist of particles, gamma radiation is a form of electromagnetic radiation, similar to X-rays but more energetic. It can penetrate materials more deeply than either alpha or beta particles, which are significantly impeded by even a thin barrier like paper or skin.
