High-energy radiation refers to types of radiation that carry a significant amount of energy, often associated with electromagnetic waves like gamma rays and X-rays. These forms of radiation can penetrate various materials and are utilized in fields such as medicine, particularly in radiation therapy for cancer treatment. The energy from high-energy radiation can also pose risks, as it has the potential to damage biological tissues. Understanding its properties and effects is crucial for both its beneficial applications and safety measures in environments where exposure may occur.
