I heard that the rudders of the Convair 990 had counterweights made out
of uranium.

- Is this correct ?
- If correct, how much urianium do we speak of ?
- What type of uranium was this ?
- Did CV990 fly during their whole (and short) life with these
counterweights or were they quikly replaced ?
- Are there other examples where radioactive materials are employed in
civil a/c ?

Just curious,
