Lovely idea Frans but beyond my capabilities

That's precisely the analogy I was thinking of, in the 60s we had
dosimeters which were small electroscopes built like a biro pen, they
were charged each day and ionising radiation gradually discharged
them. They had a miniature microscope with a calibrated scale from
which the state of discharge could be read.

The same sort of thing that counted accumulated particles passing
through it would do the job.

Frank's method is probably a bit too arcane for an amateur to use.
