Did you know that bananas are radioactive? They're radioactive enough in fact, their radioactivity has spawned its own unit of measurement of radioactivity. The banana equivalent dose (BED). The source of radioactivity is the Potassium.
Potassium is actually a radioactive element. An important and necessary radioactive element that humans need in their diet.
Quote:
A banana equivalent dose (abbreviated BED) is a nonstandard unit of radiation exposure, ostensibly defined as the additional dose a person will absorb from eating one banana.
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 contamination due to human nuclear endeavors. 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.
