Thermal noise is a much less hazardous mechanism. Ionising radiation is a pain to deal 
with, it is something one generally attempts to get rid of in a fabrication process if 
possible. Environmental radiation is a strong polluting source.

There are plenty of other quantum phenomena which can be tapped. Essentially all one 
needs to do is to build a very high gain amplifier "baddly". The main difficulty is 
removing bias. One can either go through filtering hohaa or use say MD5. The trully 
paranoid could Xor together an odd number of  MD5 samples just in case there were bit 
pattern dependencies.
