===Medical Uses of Ionising Radiation===
: '''Ionising Radiation''' can be used for both medical imaging and [[Irradiating Tumour|irradiating tumors]].
====Radioactive Tracers====
: [[Radioactive Tracers|Radioactive tracers]] can be used to image specific [[gland]]s, [[organ]]s or trace the flow of [[fluid]]s through [[organ]]s.
====Irradiating Tumours====
: The [[Irradiating Tumours|irradiation of tumours]] can be done using [[radioactive]] [[isotope]].
: [[Cancer]] [[Cell (Biology)|cells]] are more sensitive to [[Ionising Radiation|ionising radiation]] than healthy [[Cell (Biology)|cells]] so they can be targeted by a stream of [[Ionising Radiation|ionising radiation]] to kill those [[Cell (Biology)|cells]].
: One method to [[Irradiating Tumours|irradiate tumours]] is to place a pellet of [[radioactive]] [[material]] into the centre of a [[tumour]]. This pellet is encased in a protective layer (to prevent [[Radioactive Contamination|contamination]]) of other [[tissue]]s. Once the pellet has destroyed the [[cancer]] [[Cell (Biology)|cells]] it can be removed.
: Another method is to send multiple beams of [[Ionising Radiation|ionising radiation]] from different directions so that they all cross over at the same point in the body (the location of the tumour). Where the beams cross over there will be a very high [[intensity]] of [[Ionising Radiation|ionising radiation]] which will destroy the [[tumour]].
