Pioneers/Discovery of X-Radiation in Dentistry In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube. He had produced an unknown ray being emitted from the tube that could pass through the paper. He found that this new ray would pass through most objects, casting shadows of solid substances. He first investigated with his hand and was surprised when he saw his bones. His discovery would open up an exciting field for doctors because now it was possible to stu...

In this essay, the author

  • Describes professor roentgen's experiments on the effects of cathode rays. he evacuated all the air from the tube and passed a high electric voltage through it.
  • Describes how the man produced an unknown ray being emitted from the tube that could pass through the paper, casting shadows of solid substances. his discovery would open up an exciting field for doctors.
  • Explains that roentgen's x-ray discovery caused a major stir in both the medical and scientific communities. by 1896, they were being used in the us for bone fractures and gun shot wounds.
  • Describes the discovery of x-rays by henri becquerel, a french scientist, in 1896. he discovered that certain atoms disintegrate by themselves.
  • Narrates how becquerel discovered an image of the uranium on the film not due to stray light and discovered that it gave off radiation.
  • Opines that the discovery of x-radiation was one of the greatest achievements in the field of medical science.
  • Describes the pioneers/discovery of x-radiation in dentistry.
