Let’s assume you’re getting absolute time stamps or arrival intervals from your Geiger counter. How do you convert those into a uniformly random PRNG seed? They will all be biased to a small range depending on your radiation source and measurement apparatus. Secondly, non-cryptographic PRNGs leak their state from their outputs. This is a solved problem. Many academic and engineering hours have been put into real solutions. Dear reader, please use a recognized secure scheme instead of the amateur ad-hoc approach recommended up-thread. It has no theoretic or engineering basis. Don’t roll your own crypto.
