What are radioactive materials?

Radioactive materials are like tiny energy balls that never stop moving and can make other things move too.

Imagine you have a super bouncy ball that keeps bouncing forever, even when no one is pushing it. That's kind of what happens inside radioactive materials. They're made up of very small pieces called atoms, which sometimes get all excited and start shooting out little energy balls in all directions. These energy balls can make other things around them move or change too.

Radioactive materials are like a group of kids who are always playing tag, never stopping, never resting. Some of these atoms are so energetic that they even lose parts of themselves while shooting out their energy balls, and then become new kinds of atoms in the process.

You might have touched radioactive materials before without knowing it! For example, some watches use a tiny bit of radioactive material to keep them running, kind of like having a superpowered friend inside your watch helping you know what time it is.
