I think we're overestimating the extent of the threat. Hell, an attacker
could fire a particle beam at phk's geiger counter and comprise it as well.
Actually, he would just give me more random bits that way :-)
The way to use a geiger is to time three events:
e1 e2 e3
if T1 > T2
bit == 0
else if T1 < T2
bit == 1
And invert every other bit to remove any systematic bias.
