What occurs during Characteristic Radiation?

Characteristic radiation occurs when a high-energy electron collides with an inner-shell electron of an atom, knocking that electron out of its orbit. This event results in a vacancy in the inner shell of the atom. To stabilize itself, an electron from a higher energy level within the same atom falls into the lower energy vacant spot. When this transition occurs, the atom releases energy in the form of a photon, which is what ultimately characterizes this type of radiation.

The process is significant in imaging and radiation therapy because the energy of the emitted photon corresponds to the difference in energy levels between the two shells involved. This released photon can then contribute to various interactions, including production of images in radiographic techniques or affecting biological tissues in therapeutic contexts.

This understanding is crucial for professionals in the field, as it underpins fundamental concepts in radiography and patient care safety.
