- William Crookes: Pioneer of vacuum tubes; invented the Crookes Tube in 1875.
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.
Radiation Types

- Epidemic: Widespread infection in a specific geographic area.
- Pandemic: Infectious disease that spreads globally.
- Life Expectancy: Average number of years a person can expect to live.
- Health: Defined as physical, mental, and social well-being.
- Morbidity: State of having a disease or medical condition.
- Comorbidity: Occurrence of more than one illness in an individual.
- Mortality Rate: Measurement of the number of deaths in a population.
Medical Foundations
- Claude Bernard: Founder of Experimental Medicine, known for insights on the pancreas and liver functions.
- James Marion Sims: Recognized as the Father of Gynecology, invented the left lateral decubitus position.
