WHAT IS IT?

• X-rays are invisible electromagnetic radiations ableof penetrating opaque bodies and printing photographic

film. Its discovery was called'mystery ray' because he didn‘tknow what it was, or how itoccurred; nowadays it's called'X-ray'.

WHO, WHEN AND WHERE INVENTED IT?• Who: The inventor was a German

physicist, Wilhelm Conrad Röntgen.• When: On 8th of November of 1895.• Where: All this was accidentally discovered

in the laboratory of the University ofWurzburg (Germany).

• On 1st of January of 1896, he sent hiscolleagues across Europe, with details about thisamazing research and to prove it, he includedthe photo of the hand of his wife. The news spreadrapidly and his discoverer received many awards,including the Nobel Prize for Physics in 1901.

USES AND APPLICATIONS.• The discovery was a authentic revolution in Medicine and Physics.

Why: It let to understand how the illness happens inside of the human body.

• Industry: It used as a quality control method, to check out or inspect the things ( for example: the bad units can eliminate in the same place of the production)

MAN WORKING IN INDUSTRY

USES AND APPLICATIONS.

• Investigation: It's basic to know the crystalline substances and it chemical components.

AND MORE AND MORE APPLICATIONS…....

MAN INVESTIGETING

BEFORE THE DISCOVERY OF X-RAYS.

• Before of that date (8th of November of 1895), the doctors could only understand the problems or illness of the patients asking or touching their body

• For the medicine, this discovery let to study inside human body, doing year after year more accurate the diagnosis of illness.

LATEST ADVANCES IN X- RAYS

HEALTH RISKS.• Secondary effects: skin pain, redness, digestive problems, anemia, hair loss,

sterility, nauseas....• X- RAYS ARE DANGEROUS:

- Only use X-rays if it's vital.- If you are pregnant.- For babies or children .

• Radiology assistants must use a special clothing .• X-Ray Signal.

ANECDOTE

• Pedoscope (Shoe-fitting fluoroscope):

-A special machine installed in shoe stores .

- from the 1920s until the 1950s.

- in USA, Europe ( Germany, UK ..).

- It had an X-ray machine inside, so you could seethe bones of the feet.

-In the 1950s, medical organizations said it was dangerous for the health, and prohibited it.
