Basic to Intermediate Interpretation. Phillip Smith, BA, RRT. Relative Densities. The images seen on a chest radiograph result from the differences in densities of the materials in the body.. The . hierarchy of relative densities from least dense (dark on the radiograph) to most dense (light on the radiograph) include:. Wavelength the size of an atom. Frequencies above UV. Uses of X-rays. Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods. . used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye.

Normal chest X-ray anatomy. Roentgen, received the first Nobel Prize for Physics in 1901 for his work in defining the major properties of x-rays and the conditions necessary for their production. It was Roentgen who coined the term “x-ray.”. Radiation dosimetry . is the quantitative description of the effect of radiation on living tissue. . . . The absorbed dose . of radiation is the energy delivered to the tissue per unit mass. . . Used of Absorbed dose.

Warning lights and audible signals to indicate when X-rays are being generated. X Rays. Are electromagnetic radiations having wavelength of order of 1. Are highly energetic radiations which are emitted when energetic electrons are made to incident on a metallic target.. Were discovered by German Physicist W.C. Roentgen in1895..
