Key Stage 4
Meaning
Nuclear waste is the radioactive material produced in nuclear reactions.
About Nuclear Waste
- Nuclear waste emits ionising radiation and can cause irradiation of tissue or can contaminate other materials.
- Nuclear waste is produced in nuclear fission reactors and must be disposed of safely to prevent contamination of the environment and irradiation of living organisms.
- There are three so called 'levels' of nuclear waste:
- Low Level Nuclear Waste - Waste with a short 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 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 isotopes with different half lives and a high level of radioactivity so it requires shielding and cooling to prevent it heating up so much that melts or catches fire.
