Which of the following statements about radiation safety in fluoroscopy is true?

The statement regarding tabletop intensity being limited to 100 mGya/min is accurate because regulatory guidelines and safety standards have established this limit to protect patients and healthcare workers from unnecessary radiation exposure during fluoroscopic procedures.

Fluoroscopy is a type of medical imaging that uses x-rays to obtain real-time moving images of the interior of the body. Since it involves continuous radiation exposure, controlling the intensity of the radiation is critical for minimizing potential harm. Regulatory bodies, such as the National Council on Radiation Protection and Measurements (NCRP) and the American College of Radiology (ACR), have recommended limits to ensure patient safety. The limit of 100 mGya/min helps ensure adequate image quality for diagnostic purposes while reducing the risk of radiation-related complications, such as skin burns and long-term risks like cancer.

Other options do not align with these established safety protocols. For instance, stating that tabletop intensity must exceed a certain value contradicts the concept of limiting exposure to minimize risk. Claiming that intensity can vary arbitrarily across different tubes lacks a standardized approach necessary for safety in clinical settings, and suggesting there is no limit misrepresents the responsibility of healthcare facilities to adhere to safety guidelines.
