Banana equivalent dose

The banana equivalent dose (BED) is a mock unit of effective dose (E). It is equal to the committed effective dose due to the intake of the average amount of 40K in a banana.

1 BED ≈ 0.1 ╬╝Sv

Note that a banana does not contain pure radioactive 40K, but natural potassium. Eating bananas, therefore, hardly affects the committed dose in reality because our metabolism ensures that any excess potassium in the body is almost immediately excreted in the urine.
