I uploaded a version of this paper with some revisions and corrections.

I had to read it several times to figure out the relationship between GM#1 and GM#2.
Let me summarize my current understanding to see if I've got it right
Specimen ---> Mica Window --> GM#1
*- - - - - - - > *-----------------------> GM#2
GM#1 and GM#2 show counts both from the specimen and from the Mica Window
Insert lead :
Specimen ---> LEAD Mica Window --> GM#1
*-----------------------> GM#2
GM#1 and GM#2 are no longer detecting radiation from the Specimen, but are detecting the decay of K40
in the Mica window.
So the the discovery is that the radiation from the specimen is doing "something" to K40 -- which decays with a half-life of 109 minutes.
At the very least, that should be in the abstract as well as in the conclusion.
Lead-on question :
Why not use a NON-mica GM#1 AND #GM2, and then insert mica into the specimen->GM#1 path
Specimen -----------------------> GM#1
-----------------------------------------> GM#2
Insert MICA :
Specimen ---> MICA ------> GM#1
-----------------------------> #GM2
and/or
Specimen ---> LEAD MICA ------> GM#1
-----------------------------> #GM2
Then remove the mica and put it next to GM#3 to record its decay (possibly with a separate background-detector GM#4)
MICA ---> GM#3
