How are X-rays produced?When fast-moving electrons are decelerated by interaction with atoms of metals such as tungsten, the kinetic energy of the electron is transformed into X-ray photons What does an X-ray tube consist of?An evacuated tube containing two electrodes. Its components include a heater (cathode), anode, target metal and high voltage supply Why is the tube evacuated?so electrons pass through without interacting with gas atoms What is the typical p.d. of an X-ray tube for...

Features of X-rays - part of electromagnetic spectrum - high frequency = lots of energy - very short wavelength (similar to diameter of an atom) - affects photographic film in the same way as light - absorbed by metal and bone - transmitted by healthy tissue Uses of X-rays - form images of bones on photographic film: check for fractures etc. - in therapy: can be used to treat cancerous cells at/near body surface What are CCDs? Charge coupled devices. They form digital images of X-rays,...
