==Key Stage 4==
===Meaning===
'''Ionising potential''' is [[magnitude]] of the [[ionise|ionising]] effect of [[Ionising Radiation|ionising radiation]].

===About Ionising Potential===
: '''Ionising potential''' is related to the risk to living [[organism]]s of [[Ionising Radiation|ionising radiation]]. The more highly [[ionise|ionising]] the more dangerous the [[Ionising Radiation|ionising radiation]] if it is [[Absorb (Physics)|absorbed]] by living [[tissue]].
