Is it true that bananas are radioactive?

It’s true that bananas are slightly radioactive, just like how some kids get a little tingly when they eat too much candy.

Radioactivity is when something gives off tiny particles or energy because its atoms are changing. Think of it like a kid who can't sit still, the atoms inside a banana are kind of like that hyper kid, always moving and making little bursts of energy.

Bananas have a lot of potassium, which is one of those things that makes them radioactive. Some of this potassium has an extra bit inside it called potassium-40, which is the reason for all the tiny energy bursts.

You might not feel anything, but if you had a special detector, like a super-sensitive thermometer for atoms, you'd see it working.

So even though bananas are just a normal fruit you eat every day, they're also little bit radioactive, just like how some kids are always full of energy!
