Anyone of you old guys and gals remember the x-ray machines at the shoe stores...to see if your shoes fit right?

fluoroscopy is serious since it is like turning on a continuous wave of radiation...think like turning on a shower and radiation pours out. An actual x-ray is just a snapshot of gamma radiation onto a silver coated piece of film (or digital plate today)...it is not like a shower but a small quick high energy dose that is quickly over. That is why you hear a beep when u get an x-ray the beep is the actual exposure.
There was much ignorance about radiation in those days. If you find a shoe fluoroscope at Goodwill do not try to restore it
