Discovery of X-Rays
-
Wilhelm Conrad Roentgen:
- Born March 27, 1845, in Lennep, Germany.
- Married Anna Berth Ludwig in 1872 and employed at Wurzburg University in 1888.
- Conducted cathode ray experiments using the Crookes tube.
- Discovered X-rays on November 8, 1895, after noticing barium platinocyanide fluorescence.
- First radiation detector was barium platinocyanide.
- Published a report on December 28, 1895, presenting a new type of rays.
- Awarded the Matteucci Medal (1896), Elliott Cresson Medal (1897), and Nobel Prize in Physics (1901) for his work.
Radiological Developments
- Cyclotron: Invented by Earnest Lawrence in 1932; a particle accelerator that propels charged particles along a circular path.
- Radioisotopes: Produced isotopes, including Technetium-99m and Fluorine-18.
