The traditional view is that although the depleted uranium used in the manufacture of depleted uranium bombs has low radioactivity, it will still lead to the damage of human chromosomes and lead to tumors or cancer. However, in a recent study, researchers studied the blood cells of veterans exposed to depleted uranium bombs. So far, no chromosome breakage and duplication have been detected, no negative health effects caused by exposure to depleted uranium bombs have been found. Therefore, relevant researchers believe that depleted uranium bombs with low radioactivity will not affect human health.
The statement 'People who have not been exposed to depleted uranium bombs can also have tumors or cancers' would weaken the researcher's conclusion most.
