Odd trinkets containing uranium (7)
I believe the answer is:
curious
'odd' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for curious that I've seen before include "Odd, peculiar" , "Eager to learn something" , "Eager to learn, strange" , "Odd or eager to know" , "Eager to know; strange" .)
