Lead aprons are worn during fluoroscopy primarily to protect against which type of radiation?

Lead aprons are specifically designed to protect against ionizing radiation, primarily the type that is encountered in medical imaging procedures such as fluoroscopy. The correct answer, Compton scatter, relates to the interaction of X-rays with matter.

During fluoroscopy, X-ray beams are used to visualize internal structures of the body. When these X-rays enter tissues, they can interact with electrons, primarily causing Compton scattering. This process occurs when X-ray photons collide with loosely bound outer electrons in atoms, resulting in a change in direction of the X-ray and a decrease in its energy. This scattered radiation can pose a significant risk to both patients and medical staff if proper protective measures are not taken.

Lead aprons effectively attenuate the scattered radiation, significantly reducing the dose that the person wearing the apron receives. The lead in the aprons provides a barrier that absorbs and attenuates this harmful scatter, ensuring better protection.

Other forms of radiation, like alpha and beta particles, are not associated with the radiation encountered in fluoroscopy. Alpha particles are relatively large and are not able to penetrate materials such as clothing or skin, making them less relevant in this context. Beta particles, being charged electrons, also do not play a significant role in the risks faced during fluor
