  1. X-rays and their ability to The production, properties and interaction of X- rays Dr. D. MladenovaMaxillo Facial & Radiology Div.WITS DENTAL SCHOOL

  2. Properties of X-rays

  3. X-Rays were discovered by Roentgen in 1895 • They are part of electromagnetic spectrum and are invisible • X- rays are described as consisting of wave packets of energy.Each packet is called a photon and is equivalent to one quantum of energy.

  4. Longer X-rays have less penetrating power • The energy carried by x-rays can be attenuated by matter i.e absorbed or scattered

  5. An X-ray beam is made up of millions of photons of different energies • The diagnostic X-ray beam varies in its intensity and guantity • The factors affecting the intensity and/or the quantity of the beam are kV, mA, distance from the target, length of exposure, filtration

  6. Dental X-ray generating equipment • A tubehead • Positioning arm • A control panel and circuitry

  7. Ideal requirements • Safe and accurate • Capable of generating X-rays in the desired range • Small • Easy to manoeuvre and position • Stable • Easily folded and stored • Simple to operate • Robust

  8. Production of x-rays on atomic level
