Essay On Radiography

Radiography is the process of producing x-ray pictures, also known as RADIOGRAPHS. X-rays were discovered on November 8, 1895 by Wilhelm Conrad Roentgen in Germany at the University of Wurzburg. Radiographs are produced through the use of radiation. There are three different types of radiation. These include PRIMARY RADIATION, REMNANT RADIATION, and SCATTER RADIATION. Primary is the radiation that leaves the tube, remnant is the “exit radiation” that passes through the image receptor, and scatter has less energy as primary but is less controlled. The patient is the primary source of scatter and causes the unnecessary exposure of radiation known as SCATTER RADIATION FOG. The radiographs are formed in a very small are inside the X-RAY TUBE that is surrounded by a TUBE HOUSING lined with lead. The x-ray then exit through an opening on the tube housing known as a TUBE PORT. The discovery of x-rays was a revolutionary phenomenon, …show more content…
We are exposed to natural radiation at all times. Natural radiation is unavoidable. It is always present in our environment. Levels can vary greatly depending on location. People living in high mineral areas are exposed to more radiation than others. A lot of the natural exposure occurring is due to the gas radon that comes from the earth's crust and is also present in the air we breathe. When it comes to man-made radiation, one common example is nuclear weapons. However, most of the man-made radiation comes from medical procedures. This is primarily from x-rays. There are several types of personal protective equipment used in radiography. During x-rays radiation exposure can be very dangerous to the human body. PPE is always necessary to prevent unnecessary exposure. Some of the personal protective equipment used include lead aprons, thyroid collars, lead glasses, and protective gloves. All of these PPE protect from scatter radiation and limit the radiation
