What is the difference between X-radiation and gamma radiation?

The distinction between X-radiation and gamma radiation primarily lies in their source of origin. X-radiation is produced by the interaction of high-energy electrons with matter, such as when they strike a target in an X-ray tube. This type of radiation is generated artificially for diagnostic imaging and therapeutic purposes. On the other hand, gamma radiation originates from the nucleus of a radioactive atom during a decay process. As a result, gamma rays are emitted from natural sources such as radioactive materials and are associated with nuclear reactions.

Understanding the sources of these two types of radiation is crucial in fields like radiology and nuclear medicine, as it influences how they are used and the safety precautions necessary when working with each type. The differences in origin also contribute to variations in their properties, although that is not the main focus of the question.
