This article is way too list-y. Must be converted to prose, as opposed to just a list of its uses.
X-rays (or Röntgen radiation[source needed]) were a type of electromagnetic radiation. They were used in medical examinations because they penetrated soft tissue, allowing a non-invasive exam of the internal anatomy; they could also be used to examine the interiors of sealed objects using the same method. High levels of X-ray radiation could be harmful to many forms of life. When focused into a coherent beam or laser, X-rays could be used as an offensive weapon.
Instances of medical X-ray use Edit
- In the 1970s, X-rays were used on the Third Doctor at Ashbridge Cottage Hospital. They revealed his binary vascular system and astounded Dr Henderson. (TV: Spearhead from Space)
- On 31 December 1999, Dr Grace Holloway was similarly astounded at the Seventh Doctor's X-ray results. (TV: Doctor Who)
Instances of X-rays as non-medical imaging Edit
- The Mantis leader, in his attempts to learn the nature of the Doctor's TARDIS, had it subjected to X-rays, to find it was dimensionally transcendental and that the Third Doctor was inside it. (COMIC: Size Control)
- Dr Carter took X-rays of Eldrad's fossilised hand which, unlike normal fossils, didn't show any tissue differentiation (since it belonged to a silicon-based life form). (TV: The Hand of Fear)
Instances of harmful X-ray use Edit
- The Third Doctor cured Liz Shaw and Captain Harvey of their possession by a sentient virus by using an X-ray machine on them. (PROSE: Invaders Invisible)
- In 2003, the Seventh Doctor used a singularity which generated X-ray pulses to sterilise Agent Yellow, saving humanity at the cost of killing millions. (PROSE: Eternity Weeps)
- In 2008, the Tenth Doctor destroyed one of Florence Finnegan's Slabs by using his sonic screwdriver to increase the radiation of Royal Hope Hospital's X-ray machine by 5000%. (TV: Smith and Jones)
