What type of radiation exposure is associated with c-arm and fluoroscopy devices?

Non-ionizing radiation
Ultrasound radiation
Ionizing radiation
Visible light radiation

The correct answer is: Ionizing radiation

C-arm and fluoroscopy devices utilize ionizing radiation to create real-time imaging of internal structures within the body. This type of radiation has enough energy to remove tightly bound electrons from atoms, which can potentially lead to cellular damage and increase the risk of cancer with excessive exposure. Ionizing radiation is distinct from non-ionizing radiation, which includes forms such as radio waves or visible light; these have less energy and are not capable of ionizing atoms. Ultrasound radiation, on the other hand, relies on sound waves rather than electromagnetic radiation, and thus does not involve ionization. Understanding the specific types of radiation associated with various imaging technologies is crucial for ensuring proper safety protocols and minimizing exposure risks in the clinical setting.
