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

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

• 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
