Following is a link to an article I wrote for RDH Magazine on Hand Held X-Rays.
We’ve had X-ray safety protocol drilled into us since day one, and staying in the room and holding the thing is a huge no-no. We need to run from the room, preferably behind several walls and layers of lead, before we dare fire the tube head lest terrible horrors befall us.”
That type of caution was certainly appropriate when Roentgen zapped the first molar in 1895, with what I believe was a 20-second exposure. However, today’s amazing 21st century materials and equipment do in fact make it possible to stay in the room and hold the X-ray device.
