Radiation Safety Practice Exam

Which statement is true about gamma rays?

1. They are created inside the nucleus

2. They are created outside the nucleus

3. They are a form of non-nuclear radiation

4. They have lower energy than X-rays

The correct answer is: They are created inside the nucleus

Gamma rays are indeed created inside the nucleus of an atom. This occurs during radioactive decay processes when an unstable nucleus releases energy to achieve a more stable state. The energy released is emitted in the form of gamma radiation. This process distinguishes gamma rays from other forms of radiation, such as X-rays, which are produced by interactions that occur outside the nucleus, such as transitions of electrons between energy levels in atoms or when high-energy photons collide with matter. Understanding the formation of gamma rays is crucial in radiation safety, as it provides insights into how different radiation types behave and their sources. This fundamental knowledge aids in assessing risks associated with exposure to various types of radiation.
