A Correct answer
Explanation

Alpha radiation consists of helium nuclei (2 protons + 2 neutrons) emitted during radioactive decay. When a nucleus emits an alpha particle, it loses 2 protons and 2 neutrons. Beta particles are electrons, gamma rays are electromagnetic waves, and 'delta' is not a type of radiation.
