What should you never hold during an exposure to minimize radiation risk?

During an exposure, it is crucial to minimize radiation risk by ensuring that no one is directly holding any equipment that could expose them to ionizing radiation. Holding the tubehead can put an individual directly in the path of the radiation beam, which is a significant safety hazard. The tubehead emits radiation during the exposure, and being in close proximity or directly holding it increases the risk of unnecessary exposure.

Additionally, holding the film is also not advisable during the exposure. While film itself does not emit radiation, holding it could require standing in a position that may expose the holder to scattered radiation coming from the patient or the x-ray machine.

Therefore, to ensure safety protocols are strictly followed, individuals should never hold the tubehead or the film during an exposure, which is why the correct response is that all these actions increase the risk of radiation exposure. Proper safety measures involve using a film holder or an automatic positioning device to mitigate any exposure risk for the operator, thus emphasizing the importance of not physically holding either the tubehead or the film.
