This sounds like a lot of chemical jibberjabber for something that can be done with webcam noise or lava lamps.
One solution I would have is to take a software defined radio such as
http://spectrum.ieee.org/geek-life/hands-on/a-40-softwaredefined-radioTake the 3 million raw I/Q samples per second of background radio and send the data through about 10000 XORed SHA hashes to get 512 bits a second. Random.
Noise is a signal which is irrelevant and comes from many or no source in particular. It is very difficult to tease apart actual random noise from noise that is decisively NOT random.
Quantum transitons are random, and predictably so. They are also louder than the noise, which the scientist knows little about. In general, one does not know or care of the sources of noise. S/N in NQR is good enough to disregard possibly non-random noise in favor of something that is guaranteed to behave randomly in a specified manner.
It's predictably random. It behaves perfectly and cannot be mistaken for for other signal. Noise however, could be a nearby radio station - this is not so random.
Knowledge > lack thereof = "noise"
Also BTW, chaotic systems are subject to sudden non-randomness as they fall into attractors. There is no better RNG than a two level controlled quantum system.
