Which types of radiation are produced in diagnostic radiology?

In diagnostic radiology, the primary forms of radiation produced are X-rays generated through two main processes: Bremsstrahlung radiation (often referred to as Brems) and characteristic radiation.

Bremsstrahlung occurs when high-energy electrons are decelerated or "braked" as they interact with the nucleus of a target atom, which results in the emission of X-ray photons. This is a significant mechanism in X-ray tube operation, where accelerating electrons from a cathode strike a metal target, generating X-rays that are then used for imaging.

Characteristic radiation is produced when an inner-shell electron from the target atom is ejected, and an outer-shell electron falls into the lower energy state, releasing energy in the form of an X-ray photon. This type of radiation is distinct to the material of the target and is essential for producing images with specific contrast properties.

Together, these two forms of radiation are foundational in creating the diagnostic images used in medicine, allowing healthcare professionals to visualize the internal structures of patients safely. The other options do not pertain to the typical radiation types utilized in the context of diagnostic imaging in a clinical setting.
