I had an X-ray taken of my wrist last week. The X-ray technician forgot to put my shoulder and elbow in a certain position, so the X-ray had to be taken over. Isn't it dangerous for me to be exposed to extra radiation?

Sometimes human error does mean taking an extra X-ray. This can happen if the patient moves during the procedure or the technician makes a mistake.

There is concern about the effects of radiation accumulated over a lifetime. But the amount of radiation patients are exposed to in X-rays is minimized by today's modern technology.
