[ RadSafe ] Depleted Uranium as Ballast?

[Leo M. Lowe]

Hi,

This is a question from an acquaintance who is a recreational sailor.

Does anyone know of any regulations that prohibit the use of depleted 
uranium (DU) as ballast (because of its high density) in a sailboat keel, 
or in any boat?   If possible to use, where could the DU be obtained and 
what would be the approximate cost ?

Regards,
