DOD officials say exposure not a health risk to troops
WASHINGTON Depleted uranium, used to harden vehicles and armor-piercing munitions, might cause damage to DNA in ways previously not understood by health officials, according to a recently released study from Northern Arizona University.
The research could again raise questions about the military’s use of
depleted uranium, a practice Defense Department officials insist does
not present health risks to troops. The dense metal is a by-product of
the nuclear fuel enrichment process.
Theories connecting Gulf War Syndrome to radiation exposure from
uranium-laced battlefields have persisted for years. Defense Department studies show no lingering exposure danger, officials said.
A 2004 study by the Defense Department concluded that the health risks from inhaling airborne particles of depleted uranium are “very low” in combat situations.
But the new study, conducted by biochemist Diane Stearns shows that,separate from any radiation risks, cells exposed to uranium can bond with the heavy metal particles. That biochemical reaction can cause genetic mutations, which in turn can curtail cell growth and
potentially cause cancer.

☆New research on uranium's effect on DNA（ＵＰＩ通信）

FLAGSTAFF, Ariz., April 10 (UPI)−−A Northern Arizona University biochemist and her students report that uranium can damage DNA as a heavy metal independent of its radioactive properties.
Their research has enormous implications for the study of depleted
uranium as a component in military munitions.
Phys.org news agency reported on April 7 that Stearns and her students are the first researchers to discover that when cells are exposed to uranium, the uranium binds to DNA and the cells can mutate, the uranium altering the cell's DNA code. The end result can be that the affected DNA can produce a different protein or wrong amounts of protein,affecting cell growth, some of which can metastasize into cancer cells.
While scientists have long known that uranium can damage DNA as a
radioactive metal, Stearns and her collaborators discovered that uranium could also damage DNA as a heavy metal, independent of its radioactive properties.
Sterns said, "Essentially, if you get a heavy metal stuck on DNA, you
can get a mutation."
