Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

X-ray experiments in pulmonary tuberculosis proved useless. Aside from the medical profession losing faith in the ability of x-ray therapy, the public increasingly viewed it as a dangerous type of treatment. This resulted in a period of pessimism about the use of x-rays, which lasted from about 1905 to 1910 or 1912. [21]
It was in an orbit of 355 × 343 km, with an orbital period of 91.3 minutes, inclined at 51.6°. The X-ray telescope began observations on January 15, 1975. Orbiting Solar Observatory was launched on June 21, 1975. While OSO 8's primary objective was to observe the Sun, four instruments were dedicated to observations of other celestial X-ray ...
Wolfram Conrad Fuchs (1865–1908) was a German-born electrical engineer who became a pioneer in radiography.He opened the first x-ray laboratory in the United States in Chicago, and had completed over 1400 x-ray examinations by 1896.
(See X-ray astronomy). More intense research continued since 1960 including spectrometers on satellites. In the same period the laboratory spectroscopy of MIA becomes relevant as a diagnostic tool for hot plasmas of thermonuclear devices (see Nuclear fusion ) which begun with building Stellarator in 1951 by Spitzer, and continued with tokamaks ...
In addition, Fleischman would often expose herself to X-rays to show patients that the procedure was painless. [12] By 1903, the cumulative effects of seven years of unprotected X-ray exposures and twelve-hour workdays began to appear as X-ray dermatitis on her hands.
William Herbert Rollins (June 19, 1852 - 1929) was an American scientist, inventor, and dentist. He was a pioneer in radiation protection.Many of his inventions and investigations in medical radiography and photography have been ranked in importance with those of Thomas A. Edison, Elihu Thomson, and William J. Morton.
