REAL QUANTUM RNG
This device generates true random numbers from the radioactive decay of Radon-222. When a Radon nucleus undergoes alpha decay, the exact moment of emission is governed by quantum mechanics and is fundamentally unpredictable. The RadonEye sensor detects individual decay events; our entropy engine extracts the pure randomness from decay timing via Slow-Clock LSB extraction, producing cryptographically-secure 16-bit random values. Unlike computational pseudo-random generators, this is authentic quantum randomness sourced directly from nature's quantum processes.

▩ Accumulated Raw Bias — Measurement by Measurement
The line shows the accumulated absolute bias after each 16-bit measurement packet.
Early measurements are noisy and not very meaningful; after a few hundred measurements the curve should start to stabilise.
Green is healthy, orange is borderline, and red indicates the bias has moved outside the safe margin.
□ Entropy Dispersion — 16-bit Values Over Time
Each dot is a 16-bit entropy packet. Good QRNG: dots uniformly scattered across the full [0, 65535] range.
