Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
On 11 January 1896 he made the first use of X-rays under clinical conditions when he radiographed the hand of an associate, revealing a sterilised needle beneath the surface. [4] A month later on 14 February he took the first radiograph to direct a surgical operation. He also took the first X-ray of the human spine.
On January 27, 1896, Wright produced an X-ray photograph, barely a month after Wilhelm Röntgen's seminal paper On A New Kind Of Rays was published on December 28, 1895. This was the first X-ray image produced in the country. [9] He contributed numerous scientific papers, chiefly on astronomical and electrical subjects, to various publications.
Elizabeth Fleischman, American X-ray pioneer (1899) Elizabeth Fleischman-Aschheim ( née Fleischman 5 March 1867 – August 3 1905) was an American radiographer who is considered an X-ray pioneer. Fleischman was the first woman to die as a result of X-ray radiation exposure.
In 1999, Time placed Shoe-Store X Rays on a list of the 100 worst ideas of the 20th century. [29] [30] A shoe-fitting fluoroscope appeared on a 2011 episode of the History series American Restoration. [31] Its radionuclide source was found to be so dangerous that it was removed and replaced with a static X-ray. [32]
Researchers had already discovered that X-rays could kill bacteria by 1896. The predominant theory at the time was that cancer was some kind of parasitic infection. Louis Charles Émile Lortet and Philibert Jean Victor Genoud tried to kill tuberculosis in infected guinea pigs using X-rays from March to June 1896 in the same city of Lyon. [7] [3]
1896 Wilhelm Conrad Röntgen discovers the X-rays while studying electrons in plasma; scattering X-rays—that were considered as 'waves' of high-energy electromagnetic radiation—Arthur Compton will be able to demonstrate in 1922 the 'particle' aspect of electromagnetic radiation.
Homer Clyde Snook was born in 1878, at Antwerp, Ohio, to Judge Wilson H. Snook and Nancy Jane Snook (née Graves).He had 4 siblings, brothers Otto W. and Ward Hunt, and sisters Lee May and Ethel Maud.
