Wikipedia definition
2. Banana equivalent doseA banana equivalent dose (actually biologically effective dose, abbreviated BED) is a whimsical unit of radiation exposure, informally defined as the additional dose a person will absorb from eating one banana (for example). The concept is based on the fact that bananas, like most organic material, naturally contain a certain amount of radioactive isotopes—even in the absence of any artificial pollution or contamination.
