Which common medical procedure involves the use of ionizing radiation?

X-ray imaging is the common medical procedure that involves the use of ionizing radiation. Ionizing radiation has sufficient energy to remove tightly bound electrons from atoms, thus creating ions. This characteristic is the basis for how X-rays function, as they can penetrate softer tissues while being absorbed by denser substances like bones. Consequently, X-ray imaging is an essential tool for diagnosing various medical conditions, as it allows healthcare professionals to visualize the internal structure of the body.

In contrast, ultrasound imaging utilizes sound waves instead of radiation to create images, making it safe from the standpoint of ionizing radiation exposure. Magnetic resonance imaging (MRI) employs strong magnetic fields and radio waves, which do not involve ionizing radiation. Although a CT scan does involve the use of ionizing radiation, the question specifically asks for the “common” procedure among the options listed. While both X-rays and CT scans involve ionizing radiation, X-ray imaging is typically more widely utilized for basic assessments, which reinforces its classification as a common procedure in this context.
