A gamma ray is a packet of electromagnetic energy (photon) emitted by the nucleus of some radionuclides following radioactive decay. Gamma photons are the most energetic photons in the electromagnetic spectrum. Their emission commonly occurs within a fraction of a second after radioactive decay but sometimes occurs several hours later

gamma radiation, unlike alpha and beta, is waves. A substance is radioactive if its nucleus is unstable and it decays in order to become more stable. gamma rays are emitted by the substance, they are the most dangerous.
Gamma radiation is the only type that can travel through a vacuum.

There is too much energy in the nucleus of an atom so energy is released as a wave instead of particles like alpha and beta.
