But the real time of exposure to radiation is only a little, and the surgeon is there, wearing a lead coat, a lead hat and a scarf to protect him. That hat alone can't move your neck. It's very heavy
If it's someone else, then go out to the outside. In addition, the equipment itself and the operating table are protected, so there are not so many. But your hands cannot be shielded. Therefore, the main operators need to eat something light, and the patients themselves cannot escape. But the patient is disposable and the operator often has to do it. So over time, it is also eaten up in a certain amount.
If your girlfriend is a nurse, she eats very little, because she usually goes outside when the radiation is on. I won't eat it all. If you are not the main operator, then eat less. Because it doesn't really take that long to turn on the ray, and people work there, so you stay outside.
