Bananas contain potassium, and a tiny part of that potassium is radioactive. But don't worry, you'd have to eat millions of them at once for it to be dangerous!
It sounds like a superpower origin story, but it's true: bananas are radioactive. However, before you put down your smoothie, it's important to understand that this is a natural part of the world we live in.
Bananas are famous for being rich in potassium, which is an essential mineral for your heart and muscles. In nature, a tiny fraction of all potassium (about 0.0117%) is an isotope called Potassium-40, which is radioactive.
Scientists actually use a fun unit called the Banana Equivalent Dose to help people understand low levels of radiation.
Not at all. Your body is very good at maintaining "homeostasis." If you eat too much potassium, your body simply flushes the extra out. To actually get radiation poisoning from bananas, you would need to eat about 10 million bananas in one sitting, which is impossible.
Yes, bananas are radioactive, but so are you! Humans contain potassium too, making us slightly radioactive. The radiation in a banana is a tiny, natural occurrence that is completely harmless to your health.
