The term "atomic ray" refers to the beam of energy emitted by an atomic explosion or particle accelerator. There are several synonyms that are often used interchangeably with this term, including gamma ray, X-ray, and particle beam. Gamma rays are high-energy photons that are produced during radioactive decay or nuclear reactions. X-rays are electromagnetic waves with a shorter wavelength than visible light, making them useful for medical imaging. Particle beams, such as those produced by particle accelerators, are composed of subatomic particles like protons or electrons that are accelerated to high speeds and focused into a beam. All of these terms are used to describe forms of radiation that can be extremely harmful to living organisms if not controlled or shielded.
