A fire station is considering three uses of electromagnetic radiation:
| Proposed use | Radiation |
|---|---|
| Communication between crews | Radio waves |
| Finding hot areas during a search | Infrared radiation |
| Disinfecting equipment surfaces | Ultraviolet radiation |
Evaluate which of the proposed uses the fire station should adopt. In your answer, refer to the benefit of each use, any possible harm to people, and how exposure could be controlled.
