My setup is a refrigerator with a logger and a small work area I wipe down, nothing more.
I want to know whether this is a real physical effect or an artefact of how it is measured.
What prompted the question is an inconsistency between two sources I otherwise trust.
Is the standard explanation correct, and if so, what is the evidence for it?
