Banana equivalent dose
Videos
Banana equivalent dose is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by
A banana contains naturally occurring radioactive material in the form of potassium-40.
Sievert

The sievert is a derived unit in the International System of Units intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-indu

…radioactive isotopes, particularly potassium-40 (40K), one of several naturally occurring isotopes of potassium. One BED is often correlated to 10−7 sievert (0.1 μSv); however, in practice, this dose is not cumulative, as the potassium in foods is excreted in urine to maintain homeostasis. The BED is only…
