Gamma radiation is one of the three types of natural radioactivity first observed by Paul Villard in 1900. Unlike alpha particles, gamma radiation is not a particle but a wave. Specifically, it is a form of high-energy electromagnetic radiation. Gamma rays are emitted from the atomic nucleus and are among the most penetrating types of radiation, capable of passing through most materials. Hence, they require dense materials like lead for effective shielding.The symbol for gamma radiation is \(\gamma\), denoting its origination from gamma decay processes.
- Type of electromagnetic radiation
- No mass and no charge
- Symbol: \(\gamma\)
These waves are critical in various applications. They are widely used in medical treatments like radiotherapy for cancer, sterilizing medical equipment, and imaging technologies.
