You’ve probably heard the odd claim that bananas are radioactive — and that eating too many could kill you. But how worried should you be?
The Myth:
Bananas contain potassium-40, a radioactive isotope. Urban legend says eating lots of bananas could deliver a lethal dose of radiation.
The Fact:
While bananas are slightly radioactive, you’d have to eat around 10 million bananas at once to receive a deadly dose.
Scientific Takeaway:
The ‘Banana Equivalent Dose’ is a real scientific joke — bananas are harmless in everyday quantities.
Final Thought:
Relax. Your biggest banana-related danger is slipping on the peel, not glowing in the dark.
