The US Army has commission
ed ongoing research into potential risks of depleted uranium and other projectile weapon materials like tungsten, which the US Navy has used in place of DU since 1993. Studies by the US Armed Forces Radiobiolo
gy Research Institute conclude that moderate exposures to either depleted uranium or uranium present a significan
t toxicologi
cal threat. One particular subgroup of veterans which may be at higher risk comprises those who have internally retained fragments of DU from shrapnel wounds. A laboratory study on rats produced by the Armed Forces Radiobiolo
gy Research Institute showed that, after a study period of 6 months, rats treated with depleted uranium coming from implanted pellets, comparable to the average levels in the urine of Desert Storm veterans with retained DU fragments, had developed a significan
t tendency to lose weight with respect to the control group. Substantia
l amounts of uranium were accumulati
ng in their brains and central nervous systems, and showed a significan
t reduction of neuronal activity in the hippocampu
s in response to external stimuli. The conclusion
s of the study show that brain damage from chronic uranium intoxicati
on is possible at lower doses than previously thought. Results from computer-b
ased neurocogni
tive tests performed in 1997 showed an associatio
n between uranium in the urine and "problemat
ic performanc
e on automated tests assessing performanc
e efficiency and accuracy." D.E. McClain, A.C.Miller and J.F.Kalini
