Radiation Background Statistics Simulator

Interactive Geiger-counter simulator: watch a Poisson-random background radiation source regularly produce 2-3x looking 'spikes' by pure chance, and see how longer counting time narrows the confidence interval and separates real anomalies from statistical noise.

Alleged "anomalous radiation" readings near UFO sighting sites are almost always ordinary statistical fluctuation of natural background radiation, misread by an untrained observer as an anomaly. This simulator runs a real Geiger-counter-style Poisson process: a detector with a fixed, unchanging true background rate reports how many decay events it counts in each measurement window. Because radioactive decay is a Poisson process, the count in any single window fluctuates with standard deviation σ = √λ around the true mean λ — so a reading 2-3x the average happens routinely by chance alone, not because the source changed. Adjust the background rate, counting window and anomaly threshold to see how a longer count time narrows the statistical uncertainty and correctly separates a real anomaly from ordinary noise.

⚙ Under the hood

Monitor background radiation with a Poisson process that generates random spikes; longer counting times reduce uncertainty.
