gamma radiation
Light beyond X-rays
Gamma radiation is the highest-energy form of electromagnetic radiation, produced by radioactive decay and nuclear reactions.
Unlike alpha and beta radiation, gamma rays have no mass or charge, allowing them to penetrate most materials—only thick lead or concrete blocks them effectively.
Gamma radiation is used in cancer treatment, sterilization, and medical imaging, but exposure damages living tissue and causes radiation sickness.
