aren’t you glad we live in an age of PET and CAT scans rather than the fluoroscope?
this fluoroscope was manufactured by Wolf X Ray Products in the 1930s. Thomas Edison was already wary of X rays and had abandoned his search for a fluorescent lamp back in 1903. he had impaired his eyesight by experiments but was not as unlucky as his assistant Clarence Dally.
Dally was, among other things, a glass-blower, and he made the bulbs for the X-ray tubes used in the Edison laboratory. He tested them too, and he tested them by placing his hand between the fluoroscope and the light. He did this continuously, day after day, until he simply burned up the blood vessels in his hand.
“Dally made a hobby of X-rays. When Edison set up his machines in the Crystal Palace, Dally did the mechanical work. And then he put his head up in front of the light in order that people might look through it. The result was that his hair and mustache fell out.”
you can have some safe fun on this site by clicking on the fluoroscope applet, and dragging the square across the hand. it’s ok, it won’t make your hair fall out, nor your moustache if you’re unfortunate enough to have one…
