Radiation is an emission.
For example, gamma radiation from a nuclear decay is an emission of energy, photons.
Radioactivity is the term defined as the emission of energy from subatomic particles.

Radiation
Electrons are the subatomic particles found farthest from the nucleus in an atom. They move around the nucleus in defined energy levels or orbitals.
Subatomic particles of energy are photons, while subatomic particles of matter are electrons, protons, and neutrons. Electromagnetic waves propagate by the exchange of photons, which carry the electromagnetic force.
Emission of radiant energy can occur in the form of waves or particles, depending on the specific situation. For example, light is an example of radiant energy that travels in waves, while photons are particles that can also carry radiant energy.
Spontaneous emission is the process where an unstable atom or molecule releases energy in the form of particles (such as photons) or waves without any external stimulation. This emission occurs when an excited atom or molecule transitions to a lower energy state, releasing the excess energy in the process.

No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.

high-energy subatomic particles
Energy in a certain manifestation that is able to interact with other manifestations of energy.
Emission of radiant energy can occur in the form of waves or particles, depending on the specific situation. For example, light is an example of radiant energy that travels in waves, while photons are particles that can also carry radiant energy.
Neutrons are stable subatomic particles and do not decay or change into other particles under normal conditions. However, electrons do not undergo nuclear decay but can change in energy levels within an atom.
