Gamma radiation is a type of electromagnetic radiation, much like visible light but with much higher energy. Gamma rays are produced by the hottest and most energetic objects in the universe, such as neutron stars, supernova explosions, and regions around black holes. On Earth, they can be generated by nuclear reactions, radioactive decay, and certain types of high-energy physics experiments. These rays can penetrate most materials, making them both useful and dangerous. They are used in medical treatments, such as cancer radiotherapy, and in industrial applications like inspecting welds and materials. However, exposure to high levels can cause serious health issues, including radiation sickness and increased cancer risk. Understanding gamma radiation is crucial for harnessing its benefits while minimizing its risks.
