I'm not saying anything about it. Since I do not know anything special about experiments
performed with Geiger counters or other devices. 
But I try to point out something different.
An intuitive feature of classical mechanics is non-contextuality. That is, the property 
that any measurement has a value *independent* of other compatible measurements 
being carried out at the same time. 
However, Bell and Kochen & Specker have shown that non-contextuality is in conflict 
with quantum mechanics.
So, in principle,it is possible to distinguish classical and quantum effects, by means 
of contextuality, that is depending on the complete disposition of the apparatus.
I'm writing that because often I've read that psi-phenomena depend on "subjectivity"
and "contexts"!
