Abstract: The present invention provides system, devices, and methods for scanning an object while avoiding radiation exposure. For example, the present invention provides systems comprising a scanning device with input and output openings, and a safety sensor adjacent to the input or output opening that sends a signal that turns off or physically blocks electromagnetic radiation if the presence of an invading element (e.g., human hand) is detected by the safety sensor.
