⚛️ 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

Quick Recall Flashcards

What is count rate?
The number of radioactive decays (or radiation particles) detected per second or minute. Units: counts/second or counts/minute
What does a GM tube measure?
Count rate - the number of radiation particles detected per unit time (usually counts per second or minute)
