Banana equivalent dose - Wikipedia, the free encyclopedia

Banana equivalent dose - Wikipedia, the free encyclopedia: "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. The banana equivalent dose was meant to express the severity of exposure to radiation, such as resulting from nuclear power, nuclear weapons or medical procedures, in terms that would make sense to most people."

Radiation from other foods

Besides bananas, other foods that are rich in potassium (and therefore in ⁴⁰K) are potatoes, kidney beans, sunflower seeds, and nuts;^[13][14] especially brazil nuts, which may have up to 444 Bq/kg (12 nCi/kg) — four times the radioactivity of bananas.^[15][16]

By the same reasoning originally used to arrive at the banana equivalent dose, one may conclude that all the food consumed in one year results in a total exposure of about 0.4 mSv (40 mrem), which is more than 10% of the total dose absorbed from all natural and man-made sources in that same period.^[17] However, the same criticisms raised against the BED may apply to this estimate as well.^{[citation needed]"}
