It sounds fake. It’s not.
Bananas contain potassium—and a small portion of that is potassium-40, a naturally radioactive isotope.
This means every banana emits a tiny amount of radiation. Not enough to harm you, but enough that scientists jokingly measure exposure in “banana equivalents.”
You would need to eat millions at once for it to matter.
But yes—your snack is radioactive.
I’m not joking.
