  • X Rays History

    In 1895, x-rays were discovered by Wilhelm Conrad Roentgen. He was a Professor at Wuerzburg University which was in Germany. He worked with a cathode-ray tube in which he observed a fluorescent glow of crystals on a table near the tube. The tube that Roentgen was working with at the time was made of a glass envelope with positive and negative electrodes filled in it. The air that was in the tube was let out. When a high voltage was applied, the tube produced a glow that was fluorescent. He then shielded the tube with a piece of heavy black paper, discovering a green fluorescent light brought about by a material only a few feet away from the tube. Roentgen then concluded that a new type of ray was being released from the tube. The ray was capable…

  • X Rays Research Paper

    X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…

  • X-Ray Diffraction Lab

    Lab 4: Crystal Structure and X-Ray Diffraction of Materials Introduction The purpose of this experiment is to study the relationship between the geometry of a sample and its diffraction patterns through an exploration of reciprocal space. In this experiment, both a single crystal piece of Si with a (004) reflection plane and a Si powder sample are scanned, as well as the peaks the locations of the diffraction peaks on the single crystal. The collected data is then analyzed to determine the…

  • The Benefits Of X-Rays

    The three different ways X-rays can be taken are computed tomography (CT scan), fluoroscopy, and radiography (Fda.gov). CT scans are X-rays that produce cross-sectional images of the body. They are also referred to as computerized axial tomography. A fluoroscopy is a medical imaging to show a continuous X-ray image, like an X-ray movie. Radiography is the art, act or process of making radiographs and sonograms. Using radiology on it too dangerous, it can cause irreparable damage to fertility,…

  • Essay On Electromagnetic Waves

    and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission. Like Gamma, x-rays cannot be seen but unlike Gamma radiation, x-rays cannot pass through dense objects like…

  • Radiation Protection Research Paper

    X-rays were discovered in 1895 by Wilhelm Conrad Roentgen, a Professor at Wuerzburg University in Germany. While working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube. In the past, people were unaware of how harmful x-rays are, because they are invisible. Scientists and researchers working in the radiography field were not aware of the effect on the body after continuous exposure. When radiography was in its infancy, it was…

  • Essay On Mammograms

    Mammograms According to the national cancer institute, a mammogram is an x-ray vision of the human breast. The x-ray vision is used for screening purposes in facilitating the detection of tumors in the breast as well as microcalcifications such as calcium deposits that are critical in the detection of breast cancer. Mammograms used for diagnostic purposes in cases where the patient exhibits symptoms of cancer, and a tumor already detected in the breast. The diagnostic mammogram requires more…

  • Essay On Radiography

    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…
