Practise separating contamination from irradiation in radioactive-source contexts, including rocks, work surfaces, fruit treatment and carbon-14 samples.
Some of the energy stored in the nuclei of atoms can be used to generate electricity.
A nuclear fission power station generates electricity.
The daughter nuclei can cause contamination and irradiation.
Describe the difference between contamination and irradiation.
- contamination is when a non-radioactive object comes into contact with a radioactive material
- irradiation is when radiation is present
Marking guidance:
- Condone idea of exposure for 1 mark if no other mark scored.
