Lead shielding used to minimize the patient's exposure to ionizing radiation should be placed:

Lead shielding used to minimize the patient's exposure to ionizing radiation should be placed:

• A. Between the patient and the source of radiation, but not within the path of the beam that originates from the x-ray tube
• B. Between the patient and the source of radiation and within the path of the beam that originates from the x-ray tube
• C. Between the patient and the image intensifier of the fluoroscopic unit, but not within the path of the beam that originates from the x-ray tube
• D. Between the patient and the image intensifier side of the fluoroscopic unit, and within the path of the beam that originates from the x-ray tube

Answer: (A)

Reducing radiation dose relies on shielding that sits between the patient and the radiation source while staying outside the path of the primary beam. Placing lead shielding on the patient on the side facing the x-ray tube helps attenuate scattered and leakage radiation that can reach radiosensitive tissues, without blocking the actual imaging beam. If shielding were placed in the primary beam path, it would absorb the intended x-rays, degrade image quality, promote higher exposure to compensate, and defeat the purpose of imaging. Shielding positioned between the patient and the source but off the primary-beam footprint protects areas not being imaged while preserving diagnostic accuracy.
