→About Ionising Radiation
*[[Alpha Radiation]] - The [[emission]] of an [[Alpha Particle|alpha particle]] from the [[Atomic Nucleus|nucleus]] of an [[Unstable Isotope|unstable isotope]].
*[[Beta Radiation]] - The [[emission]] of a [[Beta Particle|beta particle]] from the [[Atomic Nucleus|nucleus]] of an [[Unstable Isotope|unstable isotope]].
*[[Gamma Radiation]] - The [[emission]] of a [[Gamma Ray-ray|gamma -ray]] from the [[Atomic Nucleus|nucleus]] of an [[Unstable Isotope|unstable isotope]].*[[Neutron Radiation]] - The [[emission]] of a [[neutron]] from the [[Atomic Nucleus|nucleus]] of an [[Unstable Isotope|unstable isotope]].
====Ionising Atoms====
{| class="wikitable"
| style="height:20px; width:500px; text-align:center;" |When a [[Gamma-ray|gamma-ray]] interacts with an [[atom]] the [[Gamma-ray|gammarray]] is [[Absorb (Physics)|absorbed]] by an [[electron]] in the [[Outer Shell|outer shell]] causing the [[electron]] to escape '''ionising''' the [[atom]].

: [[Neutron Radiation|Neutron radiation]] is referred to as indirectly [[Ionising Radiation|ionising]] because it does not affect the [[electron]]s [[Electron Orbital|orbiting]] an [[atom]] but it can be [[Absorb (Physics|absorbed]] by a [[Atomic Nucleus|nucleus]] making it [[Unstable Isotope|unstable]] and causing it to release a [[gamma-ray]].
===Ionising Radiation and Cancer===
: Exposure to '''ionising radiation''' is a [[Risk Factor|risk factor]] in [[cancer]] because '''ionising radiation''' can cause [[DNA]] [[molecule]]s to break. When the [[Cell (Biology)|cell]] tries to repair the [[DNA]] it can make mistakes called [[mutation]]s. If this [[mutation]] tells the [[Cell (Biology)|cell]] to replicate constantly then this becomes [[cancer]].
