  Hi again,
  
  Potatoes, carrots, lima beans and brazil nuts are all high in potassium.
  Bananas are used as the measuring tool, and a banana equivalent dose is a way of comparing amounts of radiation: https://en.wikipedia.org/wiki/Banana_equivalent_dose
  
  35 MILLION bananas is enough to be a lethal dose, so you’re pretty safe from radiation there.
