Before taking an x-ray, which of the following should be ensured about the individuals in the room?

Ensuring that nonessential persons have left the room before taking an x-ray is crucial for safety reasons. X-ray procedures involve exposure to ionizing radiation, which can pose health risks, particularly to those who do not need to be in the room during the procedure. By confirming that only necessary personnel are present, the exposure to radiation can be minimized for those who are not directly involved in the procedure.

This practice is aligned with radiation safety protocols, which emphasize the ALARA principle (As Low As Reasonably Achievable), meaning that exposure should be kept to the lowest possible level for all individuals. In addition to protecting individuals who do not need to be present, it helps maintain a controlled environment where technicians and radiologists can perform their work without unnecessary distractions or risks.
