Wilhelm Conrad roentgen was innate(p) on March 27, 1845, in Lennop, a small town in the Rhineland of Germany. His father was a wealthy textile merchant, his mother was a Dutch lady born in Appledoorn, Holland. Du lot his boyhood years Wilhelm already had a heating plant for investigates, but above all he loved record. In schooltime he was not very(prenominal) successful, not so much because of his achievement but because of his behavior. He had trouble with his teachers, resisting their authority which finally led to his dismissal. Wilhelm terminate his school years without any certificate.Because he wanted to pursue an academic circumspectioner, he had to find another way to achieve his goal. A booster dose suggested the bracingly established Poly-Technical Institute in Zurich, Switzerland. There, he applied himself and substantially earned a degree in mechanical engineering. He did not know what he wanted to do with this degree, so for awhile he did nothing. He caro uti lize with his friends. It was during this time that he met Berthe Anna Ludwig, who posthumousr became his wife. He decided to extend with post-graduate studies with the encouragement of Dr. August Kuntz.By studying hard and concentrating on the occupation at hand, he was able to obtain a doctorate in physics with a thesis on gasses. When Dr. Kuntz judge a military capability at the University of Wuerzburg, Germany, he persuaded Dr. Roentgen to go with him. In Wuerzburg he could not find work, so he tried his luck in ii other cities. even sotually the Institute of Physics at the Wuerzburg University did offer him the coveted professorial chair, which he accepted, and in 1888 Professor Roentgen was elected premier of the University. He taught during the day and spent many even outs experimenting in his lab.On the evening of November 8, 1895, while experimenting with electric current flow, using a spark conductor, he generated high voltages in a partially evacuated glass tube. The tube began to glow. He noticed that crystals of barium platino cyanide scattered on the table began to overhaul off baseless when the tube glowed. An experienced researcher, he knew he was on to something. Further tests showed that paper, wood, aluminum and some other materials were transparent to these strange glows. Even at a distance of 2 meter the rays were still stabbing a wooden door.The professor realized that he was dealing with infrared electro-magnetic rays, which under certain conditions could stimulate certain materials to fluorescence. He exposed everything he could think of to these strange new rays, among them his weight box, a wire whirl in a box and many different materials. He worked standardized a man possessed and he even slept in his lab. He found that egest glass is permeable to light but not to these rays, while wood stopped the light, but the rays passed through it. Then his thoughts dour towards jams.The bones seemed to screen the surrounding tissue papers. This massive denudation enabled man to date inside the human body for the first time. Dr. Roentgen was uncertain of the nature of his findings, so he called this phenomena X-Rays . He took a highly systematic come up to his studies and his experiments. He published a paper about the discovery and in December 1895 he held a demonstration with his first X-Ray externalises, along with one of his wifes hand. The discovery caused much excitement in scientific and health check communities throughout the world.Scientists in many countries started to experiment with these new rays, and progressive doctors very quickly used them as a diagnostic tool. A colleague, Dr. Kollicker, suggested in January 1896 to call these new rays after its discoverer. So it was done in Germany, a doctor orders a Roentgen picture, which is taken in the Roentgen department of the hospital&8212&8212- to this day. During the next decades it became obvious that X-Rays caused injury to various h uman tissue and to vision. Radioactivity was at that time not universe related to these new rays.Many researchers developed radiation burns and crab louse more than c people died. These tragedies led to greater awareness of radiation hazards for health care workers. premature in the new century X-Ray equipment was being encased, and lead barriers and lead aprons were being introduced after the hazards became known. All this eventually led to a new branch of science Radiobiology. In 1900 Professor Roentgen accepted a position at the University of Munich. One year later he received the first Nobel Prize for Physics for his discovery of X-Rays in Stockholm, Sweden.When his parents died, he inherited 2 million marks, which elevated him to the upper classes in the unripened German Empire. He traveled extensively with his wife to Italy and France, but nigh often they spent their vacation in Switzerland. He had fame and wealth and a feudal hunting lodge, but Dr. Roentgen was never re ally riant in Munich. He spent very little time furthering his research. Early in the century tuberculosis was still rampant. X-Ray examinations in wandering(a) units throughout Germany detected the disease early and prevented it from spreading. Soon X-Rays were widely used in medicine, industry and cientific research. It became an important tool in the fight against cancer in the form of radiation therapy, along with surgery and chemotherapy. Today estimator tomography is used in medicine and material testing. Since the 1960s X-Ray TV has enabled surgeons to monitor their operations. In the mid 70s micro-electronics entered the field of radiography. Today botanists use figurer tomography to examine trees for disease, and archaeologists to examine fossils, relics, artifacts and monuments. Dr. Roentgen once took an X-Ray picture of his gun. Perhaps he had a sense of things to come.One can exactly imagine airport security today without X-Rays. It is still the only trick up that w ill detect an object of potential danger in baggage or on someones person. X-Rays are not only generated here on earth the universe has been full of X-Rays for billions of years. On June 1, 1990 an X-Ray satellite was launched to search the structure and the developments of planets and the stars of the heavens. Dr. Roentgens wife, Bertha, died in 1919 after a lengthy illness, during which he had just about lived isolated in Munich. War and inflation had eroded his small fortune.Wilhelm Konrad Roentgen died four years later, on February 10, 1923 in Munich at the age of 78. His monumental discovery made a considerable contribution to the welfare of mankind. It similarly helps to unravel the secrets of nature he had loved so well. DISCOVERY OF XRAY. In late 1895, a German physicist, W. C. Roentgen was working with a cathode ray tube in his laboratory. He was working with tubes similar to our fluorescent light bulbs. He evacuated the tube of all air, filled it with a special gas, an d passed a high electric voltage through it. When he did this, the tube would recrudesce a fluorescent glow.Roentgen shielded the tube with heavy smuggled paper, and found that a green colored fluorescent light could be seen coming from a screen setting a few feet away(p) from the tube. He realized that he had produced a previously unknown invisible light, or ray, that was being emitted from the tube a ray that was capable of transit through the heavy paper covering the tube. Through additional experiments, he also found that the new ray would pass through most substances casting shadows of solid objects on pieces of film. He named the new ray X-ray, because in mathematics X is used to indicated he unknown quantity. In his discovery Roentgen found that the X-ray would pass through the tissue of domain leaving the bones and metals visible. One of Roentgens first experiments late in 1895 was a film of his wife Berthas hand with a ring on her finger (shown below on right). The new s of Roentgens discovery spread quickly throughout the world. Scientists everywhere could duplicate his experiment because the cathode tube was very well known during this period. In early 1896, X-rays were being utilized clinically in the United States for such things as bone fractures and gun shot wounds.
