To what areas does the phrase 'immediately available' apply?

• A. Only in radiography suites used for complex procedures.
• B. Only in inpatient settings.
• C. Only in areas where children are patients.
• D. All areas where ionizing radiation equipment is in use on patients.

Answer: (D)

"Immediately available" means a qualified professional who can respond right away is on-site or reachable during any procedure that uses ionizing radiation, to protect the patient and manage any problems that arise. Because ionizing radiation is used in many different settings, this requirement isn’t limited to a single room or type of procedure. It applies to all areas where ionizing radiation equipment is used on patients—whether in radiology suites, fluoroscopy rooms, CT suites, interventional labs, operating rooms during procedures, or even when portable X-ray units are used at the bedside. The safety intent is universal: ensure rapid supervision and decision-making wherever radiation exposure occurs.
