⚛️ Comparing Radiation Detectors
| Detector | Measures | Best for | Limitations |
|---|---|---|---|
| GM tube | Count rate (cpm) | Quick measurements, half-life experiments, detecting all types | Does not measure dose; less efficient for gamma; needs power |
| Film badge | Cumulative dose (mSv) | Worker dose monitoring, identifying radiation types | No real-time reading; must be developed; single use |
| Cloud chamber | Particle tracks | Visualising particle paths, identifying particle type from track shape | Complex setup; not suitable for dose measurement; gamma leaves no track |
