corpuscular radiation

(physics) Radiation consisting of subatomic particles, such as electrons, protons, deuterons, and neutrons, as distinguished from electromagnetic radiation.

Subatomic particles, such as electrons, protons, neutrons, or alpha particles, that travel in streams at various velocities. All the particles have definite masses and travel at various speeds. The properties are in opposition to electromagnetic radiations, which have no mass and travel in wave forms at the speed of light. See also radiation, electromagnetic.

Radiation consisting of streams of subatomic particles such as protons, electrons, and neutrons.

Radiation consisting of moving particles of matter, usually submolecular particles such as α-particles, protons and electrons.
