Radioactivity Concept

Measures the beta decay of Pa-234m (half-life 1.17 minutes) in real time using a Geiger-Mueller tube. Students observe exponential decay directly by plotting count rate vs. time and extracting the …

Demonstrates that repeated measurements of radioactive decay counts follow a Gaussian distribution, illustrating that individual quantum events are random but ensemble behavior is statistically predictable. Shows the Poisson-to-Gaussian transition and …
