Gamma rays

X-rays: These are electromagnetic waves with higher energy than visible light but lower energy than gamma rays. They can be used for medical imaging purposes.

Nuclear fusion: This is a process in which two atomic nuclei combine together to form a heavier nucleus, releasing a large amount of energy, including gamma rays.

Radiation therapy: It is a medical treatment that uses high-energy radiation (such as gamma rays) to kill cancer cells or shrink tumors.
