“Here’s what the Oak Ridge Associated Universities has to say; (ORAU was founded in 1946 as the Oak Ridge Institute of Nuclear Studies.): ‘The human body maintains relatively tight homeostatic control over potassium levels. This means that the consumption of foods containing large amounts of potassium will not increase the body’s potassium content. As such, eating foods like bananas does not increase your annual radiation dose. If someone ingested potassium that had been enriched in K-40, that would be another story.’
