==Key Stage 4==
===Meaning===
'''Nuclear waste''' is the [[radioactive]] [[material]] produced in [[Nuclear Reaction|nuclear reactions]].

===About Nuclear Waste===
: '''Nuclear waste''' [[emit]]s [[Ionising Radiation|ionising radiation]] and can cause [[irradiation]] of [[tissue]] or can [[Radioactive Contamination|contaminate]] other [[material]]s.
: '''Nuclear waste''' is produced in [[Nuclear Fission Reactor|nuclear fission reactors]] and must be disposed of safely to prevent [[Radioactive Contamination|contamination]] of the [[environment]] and [[irradiation]] of living [[organism]]s.
: There are three so called 'levels' of [[Nuclear Waste|nuclear waste]]:
:*[[Low Level Nuclear Waste]] - '''Waste''' with a short [[Half Life|half life]] and a low level of [[radioactivity]] so does not require shielding or cooling.
:*[[Intermediate Level Nuclear Waste]] - '''Waste''' with a short [[Half Life|half life]] and a medium level of [[radioactivity]] so it requires shielding, but does not require cooling.
:*[[High Level Nuclear Waste]] - '''Waste''' with a many different [[Unstable Isotope|unstable isotopes]] with different [[Half Life|half lives]] and a high level of [[radioactivity]] so it requires shielding and cooling to prevent it heating up so much that [[Melting|melts]] or catches fire.

 :*[[Intermediate Level Nuclear Waste]] - '''Waste''' with a long [[Half Life|half life]] and a medium level of [[radioactivity]] so it requires shielding, but does not require cooling.
 :*[[High Level Nuclear Waste]] - '''Waste''' which extremely [[radioactive]] but will not remain so for more than a few decades due to a short [[Half Life|half life]]. After around 50 years this becomes [[Intermediate Level Nuclear Waste]]. It requires shielding and cooling to prevent it heating up so much that [[Melting|melts]] or catches fire.
