Gamma Ray
What is Gamma Ray?
Gamma rays are high-energy electromagnetic radiation emitted by atomic nuclei during radioactive decay or nuclear reactions, having no mass and no charge. They have the highest energy and shortest wavelength of all electromagnetic radiation, typically with energies exceeding 100 keV, and can penetrate deeply into matter. Gamma radiation is used in medical imaging, cancer treatment, sterilization of medical equipment, and food irradiation.
