gammastrålarna

Gammastrålarna, or gamma rays, are a form of electromagnetic radiation. They have very high frequencies and short wavelengths, making them the most energetic form of light. Gamma rays are produced by radioactive decay, nuclear reactions, and high-energy astronomical phenomena like supernovae and pulsars. They have the ability to penetrate matter deeply, which is why they are used in medical imaging, radiation therapy to treat cancer, and in industrial applications like sterilization. However, due to their high energy, gamma rays can also be harmful to living organisms, causing damage to cells and DNA. Protection against gamma radiation typically involves dense materials like lead or concrete. In astronomy, gamma-ray bursts are some of the most luminous events in the universe.
