The x-ray tube was removed to render the apparatus harmless before being put on public display, due to the possible risk of radiation burn or other health problems if it were switched on. The risk of radiation burns to extremities was known since Wilhelm Röntgen 's 1895 experiment, but this was a short-term effect with early warning from ...
X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered on November 8, 1895, by the German physicist Wilhelm Conrad Röntgen.The first-generation cold cathode or Crookes X-ray tubes were used until the 1920s.
The "X-ray meter," as the quadrant is called, thus furnishes an easy means of comparing the intensity of Rontgen ray emitted by different tubes and by the same tubes at different times."

This unit of radiation exposure was named the roentgen in honour of Wilhelm Röntgen, who had died five years ...
