Gamma rays are a form of electromagnetic radiation with the shortest wavelengths and highest frequencies in the electromagnetic spectrum. They are characterized by their ability to penetrate most materials, making them highly effective in medical imaging and cancer treatment, as well as in sterilizing medical equipment. Gamma rays are produced by the decay of atomic nuclei, certain subatomic particle interactions, and astronomical phenomena such as supernovae and the decay of radioactive isotopes in space. Due to their high energy, gamma rays can pose significant health risks, such as DNA damage leading to cancer, necessitating careful handling and protection measures when they are used in industrial and medical applications.
