How is this way more radioactive than uranium?

How is this way more radioactive than uranium?

Whatever’s in here is extremely radioactive, and it’s worse than when I tested nearly pure uranium. Inside it doesn’t actually look very scary, and it’s just some small pieces of metal. These are just watch dials, but that they’ve been covered in paint that contains radium. Radium is an extremely radioactive element, and pure radium is way more radioactive than uranium.
