The correct term for the ability of X-rays to remove tightly bound electrons from atoms is ionization. Ionization occurs when an atom gains enough energy to liberate an electron, resulting in the formation of an ion. X-rays, being a form of ionizing radiation, carry sufficient energy to break atomic bonds, thus displacing electrons from their orbits around the nucleus. This process is significant in various fields, particularly in medical imaging and radiation therapy, as it can affect biological tissues and lead to important physiological effects.

The other terms do not accurately describe this specific process. Radiation refers broadly to the emission of energy as electromagnetic waves or as moving subatomic particles. Irradiation generally involves the exposure of a substance to radiation, but does not specifically address the removal of electrons. Exposition, while related to exposure, is not a standard scientific term associated with X-ray physics or the process of ionization.
