Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that bananas emit measurable radiation because they contain radioactive potassium-40?

Yes. The EPA states bananas are a well-known radioactive food because a small fraction of their potassium is radioactive, delivering about 0.1 microsieverts per banana, and a Wikipedia article explains this comes from potassium-40 at roughly 15 Bq per banana. A scintillator thesis briefly lists bananas among radiation sources without detail.
