X-ray Device: Discovery, Design and Application One of the important discoveries of mankind has been X-rays. Since its discovery, implementation, renovation and modification, it has been useful enormously in the field of medicine and other areas and has been useful in diagnostic technology, scanning and treatment.
The discovery was actually accidental. The scientist found that invisible rays were emitted from a cathode ray tube and that these could penetrate wood and also paper. These rays were able to create a glow on a screen that was several years yards away. The glow was fluorescent. The screen that was observed was barium platinocyanide screen (Assmus, 10). The tube generating X-rays, the cathode rays was Crookes tube (Assmus, 10). The scientist made use of these properties to study the structure of bone of human hand. Several years after discovery of these rays, actual X-ray machines were invented. In 1900, it was discovered that radium rays are actually dangerous to skin. Radiology began to emerge as one of the medical specialities in 1900. Skill, the technical know-how and interpretation of image improved significantly (Linton, 27) X-rays are basically electromagnetic waves and their behavior is similar to light rays (Dendy, 48). However, their wavelengths are short. One useful property of the X-rays is, when the rays are directed towards a target that is of low density, they pass through the target uninterrupted. In case the target is of high density, like that of parts of human beings, the X-rays either get absorbed or are reflected. ...
