A radiological assessment was conducted in Kosovo in December 1999. It showed the importance of carrying out a radiological survey as soon as possible when deploying troops in territories under reconstruction, so that appropriate protective measures can be taken. The results show that it is not possible to detect depleted uranium in the environment. This radionuclide, however, could be identified in some smear samples collected in the shell hole and in those collected in shell casings. The risks turned out to be negligible.
