How long does a x-ray technician have to wait re-enter the room after an exposure?

The amount of time an X-ray technician has to wait to re-enter the room after an exposure depends on the type of X-ray machine being used and the radiation levels in the room. In general, technicians must wait at least 15 seconds before re-entering the room if using a conventional X-ray machine, and at least 30 seconds if using a mobile X-ray machine. However, if the radiation levels in the room are high, the technician may need to wait longer. Additionally, some states have specific regulations regarding how long X-ray technicians must wait before re-entering the room after an exposure, so it is important to check local regulations for specific requirements.
