A year after Röntgen's discovery of X-rays in 1895, the American engineer Wolfram Fuchs gave what was probably the first radiation protection advice, but many early users of X-rays were initially unaware of the hazards and protection was rudimentary or non-existent. [11] The dangers of radioactivity and radiation were not immediately recognized.
Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. [1]
An autoradiograph is an image on an X-ray film or nuclear emulsion produced by the pattern of decay emissions (e.g., beta particles or gamma rays) from a distribution of a radioactive substance. Alternatively, the autoradiograph is also available as a digital image (digital autoradiography), due to the recent development of scintillation gas ...
Some former East German dissidents claim that the Stasi used X-ray equipment to induce cancer in political prisoners. After the fall of the Socialist Republic of Romania, files released indicated that the secret police, Securitate, had intentionally induced cancer in striking miners. [citation needed]
Industrial Radiography uses either X-rays, produced with X-ray generators, or gamma rays generated by the natural radioactivity of sealed radionuclide sources. Neutrons can also be used. After crossing the specimen, photons are captured by a detector, such as a silver halide film, a phosphor plate, flat panel detector or CdTe detector.
Vidisco is an Israeli based developer and manufacturer of portable digital X-ray inspection systems.. The company was founded in 1988 by Shlomo Shapira, to develop digital portable X-ray inspection of unexploded ordnance, [2] the company has since developed a range of digital X-ray inspection devices for both the security and industrial testing markets.

The disposal team consisted of 24 men who were restricted to a maximum of 40 seconds worth of exposure (max. 20mSv) each while transferring the canisters to lead-lined drums. [ 56 ] March 11, 2002 – INES Level 2 – A 2.5 tonne 60 Co gamma source was transported from Cookridge Hospital , Leeds , to Sellafield with defective shielding [ 57 ...
Many of Superman's abilities are at the player's immediate disposal. Flight and super strength are inherent, super hearing assists with the game's radar system, X-ray vision is important for searching for bombs or other weapons, and freeze breath is widely used for putting out fires.
