WILHELM CONRAD RÖNTGEN 8 lokakuuta 1895 Röntgen havaitsi, että tyhjiöhehkulampusta, jonka läpi johdettiin korkeajännitteinen sähkövirta emittoi ennestään tuntematon säteilyä. Säteily aiheutti hehkua pieneen barium-platina-syanidilevyyn. Seuraavien viikkojen aikana, tiiviin työskentelyn tuloksena Röntgen määritteli röntgensäteiden ominaisuudet. Röntgenin keksintö aiheutti valtaisaa huomiota tiedemiespiireissä. Hän ei patentoinut keksintöään, eikä yrittänyt hyötyä siitä taloudellisesti. Kaupalliseen käyttöön tarkoitetut laitteet tulivat nopeasti saataville, ja jo muutaman kuukauden kuluttua niitä käytettiin sairaaloissa mm. vieraiden esineiden etsimiseen potilaan ruumiista ja apuna luunmurtumien hoidossa. Wilhelm Röntgen oli jo ennen keksintöään laajalti arvostettu tiedemies ja häntä pidettiin yhtenä loistavimmista kokeellisista fyysikoista Saksassa hänen aikanaan.

Rontgen discovered that X-rays (electro-magnetic radiation) could penetrate solid substances and be recorded onto photographic plates in the same way as light. Rontgen published his findings in December of 1895, and by the next year, X-ray machines were being installed in hospitals. In 1901 he was awarded the Nobel Prize. For the first time, doctors were able to view the insides of the body without having to perform surgery. X-ray machines became immediately popular and were essential tools for surgeons operating on wounded soldiers during the First World War. Portable machines were taken into the battlefield and were used to locate bullets and shrapnel from exploded bombs. Memory time...

His achievement heralded the age of modern physics and transformed medical practice. Wilhelm Conrad Roentgen was born on March 27, 1845, in Lennep, Prussia. Educated in The Netherlands and Switzerland, Roentgen obtained his doctoral degree in physics at the University of Zürich in 1869. He conducted research and taught at the universities of Strasbourg, Giessen, Würzburg, and Munich. In 1895 Roentgen began experiments at the University of Würzburg with an electric current flow in a partially evacuated glass tube (known as a cathode-ray tube). He noticed that, whenever the tube was in operation, a piece of barium platinocyanide in line with it gave off light. Roentgen theorized that the interaction of electrons striking the tube's glass wall formed an unknown radiation that caused the fluorescence. He called the mysterious phenomenon X radiation, or X rays. Further experiments revealed that X radiation produces an image on photographic plates and penetrates many materials such as paper, wood, certain metals, and living tissue. For the first time physicians had a nonsurgical tool to see inside the body. The medical and scientific uses of X rays spread quickly throughout Europe and the United States.

Radioactivity was at that time not being related to these new rays. Many researchers developed radiation burns and cancer; more than 100 people died. These tragedies led to greater awareness of radiation hazards for health care workers. Early in the new century X-Ray equipment was being encased, and lead barriers and lead aprons were being introduced after the hazards became known. All this eventually led to a new branch of science: Radiobiology. Early in the century tuberculosis was still rampant. X-Ray examinations in mobile units throughout Germany detected the disease early and prevented it from spreading. Soon X-Rays were widely used in medicine, industry and scientific research. It became an important tool in the fight against cancer in the form of radiation therapy, along with surgery and chemotherapy. Today computer tomography is used in medicine and material testing. Since the 1960's X-Ray TV has enabled surgeons to monitor their operations. In the mid 70's micro-electronics entered the field of radiography. Today botanists use computer tomography to examine trees for disease, and archaeologists to examine fossils, relics, artifacts and monuments.
