Radioactivity [r]: The property of the unstable nuclei of chemical elements to decay into another isotope, emitting energy or particles ^[e]
Ionizing radiation [r]: Subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them. ^[e]

Instrumentation for radioactivity [r]: Devices that variously detect, measure and characterize radioactivity; they may be intended for field or laboratory use ^[e]
Health physics [r]: The science concerned with problems of radiation protection relevant to reducing or preventing radiation exposure, and the effects of ionizing radiation on humans and their environment ^[e]
Acute radiation syndrome [r]: Disease or death caused by whole-body irradiation, over a short period of time, with a significant quantity of penetrating radiation ^[e]

Alpha particle [r]: helium nucleus; particle of charge 2e and mass 4 u. ^[e]
Beta particle [r]: A high-energy electron or positron emitted, along with a neutrino, by the decay of an atomic nucleus; a form of ionizing radiation ^[e]
Electronvolt [r]: Unit of energy; 1 eV = 1.602 176 487 × 10⁻¹⁹ joule ^[e]
Gamma ray [r]: Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during nuclear decay. ^[e]
Neutron [r]: An elementary particle of neutral charge, normally found in the nucleus of chemical elements, but having significant effects when in free flight; the number of neutrons in the nucleus of an element defines its identity as an isotope ^[e]
X-ray [r]: An ionizing type of electromagnetic radiation whose absorption or diffraction often used for structural investigations of matter. ^[e]
