About Radiography
Radiography is the use of X-rays to view areas or objects that are normally not visible. X-rays are a form of radiation, focused into beams, which are able to pass through some materials and most types of tissue in the human body. Dense materials and tissue, such as bones, absorb X-rays and cause them to bounce back and appear white on film. This enables scientists, physicists, researchers, and other professionals to see inside the human body or detect hidden flaws in materials that would otherwise not be visible. The invention and advancement of radiography has greatly improved the diagnosis and treatment of medical conditions and has led to safer and more reliable manufacturing techniques.
Radiography Treatment
Radiography treatment is used to treat cancer. Radiography treatment is more commonly known as radiation therapy . It is the use of radiation as medical treatment, usually for forms of cancer. The therapeutic goal of radiation therapy, also known as radiotherapy, X-ray therapy and irradiation, is to kill cancer cells while doing as little damage as possible to normal cells. Unfortunately, it is never possible to completely avoid damaging normal cells during radiation therapy, so there will also be some degree of toxic effects from treatment.
Wilhelm Conrad Röntgen
The 8th of November will be celebrated by radiographers worldwide as World Radiography Day to commemorate Wilhelm Conrad Roentgen’s discovery. On this day in 1895, Professor Roentgen was working with cathode rays using evacuated glass bulbs. He noted that when a current passed across the bulb, a barium platino-cyanide screen fluoresced and furthermore he noted the effect of the phenomenon on photographic plates. He termed this new discovery ‘X-Rays’. He further asserted that, with the use of these ‘X-Rays’ he was able to see through the body.Within three months of Roentgen’s discovery, radiographs were generated in major cities.
srt2007feb would like to encourage radiographers all over the world to celebrate this great discovery. World Radiography Days an annual international initiative intended to raise awareness of, and to stimulate an interest in, the profession of radiography. In addition it is aimed at highlighting the importance of radiography and the indispensable function it plays in the health care environment.

Mrs. Röntgen's hand, the first X-ray picture of the human body ever taken.
On 8 Nov, 1895, Wilhelm Conrad Röntgen (accidentally) discovered an image cast from his cathode ray generator, projected far beyond the possible range of the cathode rays (now known as an electron beam). Further investigation showed that the rays were generated at the point of contact of the cathode ray beam on the interior of the vacuum tube, that they were not deflected by magnetic fields, and they penetrated many kinds of matter. A week after his discovery, Rontgen took an X-ray photograph of his wife's hand which clearly revealed her wedding ring and her bones. The photograph electrified the general public and aroused great scientific interest in the new form of radiation. Röntgen named the new form of radiation X-radiation (X standing for "Unknown"). Hence the term X-rays (also referred as Röntgen rays, though this term is unusual outside of Germany).
