Gamma radiography:
![gamma use](https://www.tutormyself.com/wp-content/uploads/gamma-use.png)
Medical tracer: – Radioactive tracer put in body (swallowed/injected) – Detector put around body – Computer generates an image |
Gauging: – Coal absorbs a lot of radiation – If only a small amount of radiation is detected back after it is reflected by what you are trying to gauge, lots of coal is present. |
Radiotherapy
- High doses of radiation are directed at cancer cells
- Cancer cells are killed
Pipe tracers: – A radioactive material which emits gamma radiation with a short half-life is put in the water – A detector is placed above the pipe – A spike in detected radioactivity suggests a leak in the pipe |

Sterilisation:
- Medical equipment irradiated
- Kills all living matter on tools (e.g. bacteria)
