history of radiography

fouding father of x-ray

Wilhelm Conrad Roentgen

professor of University of Wertzburg

Germany

win nobel prize 1901 (very first one for physics)

x-ray discoverd

11/8/1895

discover x-ray using what

Crooke’s Tube using barium platinocyanide (green color light)

first x-ray

hand of ana bertha roentgen (his wife)

“I saw death”

wait 15 to 30 minute

picture has kid take x-ray arm. the guy next to him is ?

Eddie Mccarty

thomas edison discover

fluoroscopy

X-ray vision

People at this time thought they could see through the clothes

Marie Curie

extracted radium from pitchblende

1899 Radium

she and her husband Pierre discovered pyroelectric effect crystals used for ultrasound

radithor

1928

radithor contained 1 microcurie each of ra-226 and ra-228. A.M.Byers died from drinking Radithor

radiation product

tho-radia face cream (make skin white)

using in France in the early 1930s contain 0.5g thorium chloride and 0.25 mg radium bromide

radium wath dials

early 1900 (radium girls)

radium bread (radium water use of loaves)

Scrotal Radiendocrinator

suppose to invigorate sexual virility

Inventor of the radiendocrinator, William Bailey (invented Radithor) died form bladder cancer

properties

1. travel in straight lines (many areas, many ways but always straight)

2. Invisible

3. Highly Penetrating (strong light can see bone)

4. darken photographic film

5. polyenergetic (some x-ray strong, some weak)

6. cause ionization (means most of the film will light up when exposed to radiation)

7. electrically neutral

8. chemical & biological changes

9. causes scatter radiation (weaker strength of x-ray)

10. causes secondary radiation (bound off patient goes to technologist)

11. travel at the speed of light

12. produces a small amount of heat during interactions

13. causes certain chemicals to fluoresce (barium platinocyanid)

14. cannot be focused by a lens
