WebX-rays are produced by means of a cathode ray tube, which is similar to the tube of a television. Electrons are accelerated from a cathode at high speed towards a metal anode. As they hit the metal anode, they release energy. Over 95% of this energy is released as heat and less than 5% of the electrons' energy is converted into x-rays. WebX-rays are similar to gamma rays however the main difference is the way they are produced, ... It is this penetrating power that allows us to take internal images of the human body or objects.
