Tell contamination by radioactive material apart from irradiation, then choose measures such as gloves, distance or shielding for the hazard.
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
