Banana Equivalent Dose

Bananas are radioactive. They’re rich in potassium and about 0.012% of potassium is potassium-40, a radioactive isotope.

Don’t worry though, you would need to eat 10,000,000 bananas in one go or 274 bananas a day for 7 years to get a fatal dose of radiation. There is even a measure of radiation called the Banana Equivalent Dose.
