The best protection from radiation for anyone other than the patient is distance. The principle of distance is based on the inverse square law, which states that as the distance from a radiation source increases, the intensity of radiation exposure decreases dramatically. Specifically, doubling the distance from the source can result in a reduction of radiation exposure to one-fourth of the original level. This concept is crucial in minimizing radiation exposure for healthcare workers and anyone else in the vicinity during diagnostic imaging procedures.

While lead shielding is an important protective measure, particularly for specific body parts, it does not provide the same level of overall protection that increasing distance does. Shielding can block radiation effectively, but it does not alter the original intensity of the radiation at the source. Time involves minimizing the duration of exposure to radiation, but distance proves to be the most effective means of protection as it reduces the exposure rate itself. Patient positioning is essential for obtaining quality images and ensuring the safety of the patient, but it does not specifically address radiation protection for others. Therefore, prioritizing distance remains the most effective method of ensuring safety from radiation exposure.
