A sealed radiation source typically emits what kind of radiation?

A sealed radiation source typically emits gamma rays due to their penetrating ability and energy characteristics, making them suitable for various applications in medical, industrial, and research fields. Gamma rays are a form of electromagnetic radiation that can travel significant distances and pass through materials more easily than alpha or beta particles. This characteristic is particularly valuable for diagnostic imaging in medicine (like gamma cameras) and for therapy in radiation treatments, where the goal is to target tissues while minimizing exposure to surrounding areas.

While alpha particles and beta particles are also associated with certain radioactive materials, they are generally found in unsealed sources or materials that are not designed for the same applications as sealed sources. Neutrons, on the other hand, are less common in sealed applications due to their unique interactions and the specialized equipment required for handling and detection. Therefore, gamma rays are the primary type of radiation emitted by sealed sources, making this choice the most accurate in the context of radiation safety and the use of sealed sources.
