Please expand on how the run was conducted...
I cut and folded a fresh strip of printer paper, taken from a closed ream package. I left the paper sitting face-up for ~12 hours next to the lead cave that is part of the test bench, about 20 cm from the cell. The test paper was thus shielded from the cell by about 15 cm of lead bricks.
Then I placed the paper( inverted) on the GMC pancake detector, which had been left in its horizontal orientation (face up). I put each of the metal foils on top of the paper, singly in sequence as done for the "live" test. The measurement times and thus duration are shown in the text log I posted along with the data file.
Today's follow-up live radiation test is delayed a few hours, to run hopefully around 21:00 UTC
