A long time ago I bought a geiger counter for crypto 
exploration.  Problem is, you can't buy rad sources strong enough to 
generate enough entropy (which is *still* subject to conditioning of 
course, despite the hype, and any way a GM tube will 
saturate..).  Even if you take your smoke detector apart and use an 
alpha-windowed tube.

But a detuned FM radio card seemed to do quite well.  Admittedly, no 
white vans driving my amps.  Are these sources not supported as 
entropy sources?   (Pardon my linux randomness being out of date)

Also, why u no trust Intel's RNG? :-)
