= Delta ray
{wiki=Delta_ray}
Delta rays are high-energy electrons that are ejected from matter as a result of ionizing radiation interactions. When charged particles, such as alpha or beta particles, pass through a material and lose energy through various interactions, they can sometimes impart enough energy to nearby atoms to eject electrons from them. These ejected electrons are referred to as delta rays. Delta rays are characterized by their relatively high kinetic energy and their ability to cause further ionization along their path as they travel through the material.
