They claim to have a true random event generator. They do not explain
its working. Please advise: how does it work?

I thought so, but I am not an expert. Thanks. Sampling the emission
would then not have to be regular which makes it simple. Cool!

The sampling electronics may be quite regular, but that which is
sampled (the presence or not of an emission particle) is not, thus the
measured results are considered random on physics principles.
No one knows what is really going on at the quantum level where
the emission occurs. The man made electronics are very deterministic
and regular.

The REGs used at PEAR were based on noise generated
by a reverse biased semiconductor diode. I couldn't find
info at the psyleron web site about what they use, but
I suspect it might be the diode method like Jahn used
at PEAR ... unless you're you happen to be certain that
Psyleron REGs use radioactive decay.

Oh man, way out of my field. I merely need to know that the device
produces truly random 1 or 0.

Is this the same as an unpredictable event? Like a random number
generator?

Here we go again.

What difference does it make what term you use as long as you are
clear about the meaning? Various disciplines use the term random
without regard for how other disciplines use it, so you have to
specify the characteristics you are talking about. We don't really
know what John means, perhaps because he doesn't know himself.

Let's say he is designing a computer program to generate 'random'
numbers. How will he test it? He must define a test, and once we read
his specifications we will know what he means by "random". If you
wish to design a machine to give 'unpredictable' results, then you
should do the same.

If he test his machine with the device he mentions in his OP, then his
definition is "that which produces results like the psyleron device".

There are no random events per se. A random event means an event that
