I'm not aware of anything, but it certainly is something that ought to be researched because it would be completely different if we had a way of measuring exposure, not just to depleted uranium, but to arsenic, nickel, cadmium, or anything else that soldiers might be exposed to, which you don't necessarily find in the day-to-day environment. The only thing that they have as badges are for external radiation, in case of a nuclear situation. This is external radiation in large doses, gamma radiation, which does not apply to depleted uranium, but it would have been simpler.
This is the limiting factor in very many studies in any country.
