They are consumed in huge quantities all over the globe

There are many reasons for this popularity. Bananas are tasty, portable, affordable, and nutritious

They are a good source of potassium, fiber, vitamin B6, and vitamin C

But there is one more little strange fact about bananas: they are radioactive

According to BBC Science Focus, bananas contain potassium-40, a radioactive isotope, making them slightly radioactive

A lorry full of bananas can trigger radiation detectors due to this radioactivity, but eating bananas won't make you radioactive as humans already contain potassium-40

In fact, the average adult is 280 times more radioactive than a banana due to their potassium content

Eating a banana temporarily increases your potassium-40 levels, but your body quickly regulates and excretes the excess

This effect is detectable with a sensitive Geiger counter
