Right, Serbia's cancer rate must be because of depleted uranium bombs, not that Serbia has one of the highest smoking rates in the world. Also, studies have found NO elevated rates in the soil.
A team of Italian scientists from the University of Siena reported in 2005 that, although DU was "clearly" added to the soil in the study area, "the phenomenon was very limited spatially and the total uranium concentrations fell within the natural range of the element in soils. Moreover, the absolute uranium concentrations indicate that there was no contamination of the earthworm species studied."[151]
In 2018, Serbia set up a commission of inquiry into the consequences of the use of depleted uranium during the 1999 NATO bombing of Yugoslavia in southern Serbia and its link to the rise of diseases and tumors among citizens, particularly in young children born after 1999. Zoran Radovanovic, an epidemiologist and the chairman of the Serbian Medical Association's ethics committee, denied that there had been a rise in cancer cases in areas where bombings had taken place. He continued by saying that Serbians frequently worry about a cancer epidemic that does not exist.[152] NATO has repeatedly claimed that depleted uranium found in the ammunition used in the 1999 bombardments cannot be linked to adverse health effects.[153
Serbia occupies the sixth position in the world. 40.6 percent of the Serbian population smokes, of which 40 percent are men and 41.2 percent are women.
