Depleted Uranium is what is left after radioactive isotopes are extracted from natural uranium found in soils. Those radioactive isotopes may be used to enrich natural uranium for energy use. The resulting depleted uranium is 60% as radioactive as you may find in the soil in your backyard. The Royal Society did a full study of health effects of depleted uranium on the battlefield here is the link:

”Royal Society Summary:
The Part I report draws the following conclusions:
Except in extreme circumstances any extra risks of developing fatal cancers as a result of radiation from internal exposure to DU arising from battlefield conditions are likely to be so small that they would not be detectable above the general risk of dying from cancer over a normal lifetime.
The greatest exposures will apply only to a very small fraction of the soldiers in a theatre of war, for example those who survive in a vehicle struck by a DU penetrator. In such circumstances, and assuming the most unfavourable conditions, the lifetime risk of death from lung cancer is unlikely to exceed twice that in the general population. . .
“Depleted uranium is used in munition shells and for tank protection from penetration by enemy fire. It's used because it's density and hardness are greater than lead.”
“That's why depleted uranium is used instead of lead. Lead can be alloyed with other metals to create a dense AND hard surface, but that usually sacrifices some of it's density properties, and definitely it's melting point properties. But depleted uranium is used instead of lead in MANY applications where lead or lead alloy used to be used. One of the primary substitutions for lead now, is in the PROTECTION of individuals from exposure to radiation. Due to the density of uranium, it's radiation protection properties are superior to that of lead.”
“Here are some more links with reliable third-party scientific data on the health effects of DU.”
arps.org:
"The risk from external exposure is essentially zero, even when pure metal is handled. No detectable increases of cancer, leukaemia, birth defects or other negative health effects have ever been observed from radiation exposure to inhaled or ingested natural uranium concentrates, at levels far exceeding those likely in areas where DU munitions have been used. This is mainly because the low radioactivity per unit mass of uranium means that the mass needed for significant internal exposure would be virtually impossible to accumulate in the body – and DU is less than half as radioactive as natural uranium."
“The conclusions of three authoritative overseas studies can be summarised as follows:”
RAND Corporation – There is no evidence of radiological health effects, or of increased kidney disease in troops with embedded fragments.
US Department of Health and Human Services Agency for Toxic Substances and Disease Registry – No radiological health hazard is expected from inhalation, dermal or oral exposure to depleted or natural uranium.
National Academy of Sciences Institute of Medicine – Studies of effects "are suggestive of no association" with DU.

Public Information
”Health physicists are deeply concerned with the public health and welfare and, as experts in radiation and its effects on people and the environment, are quite aware that something other than exposure to uranium is the cause of the illnesses suffered by those who have had contact with depleted uranium from munitions. If we are to offer any measure of relief or solace to suffering people, and to gain some important additional knowledge in the process, we should not squander our valuable and limited energies, resources and time, traveling down a road that has already been well traveled and which has already shown us that uranium, either by itself or in combination with other materials, is almost certainly not the culprit.”
“Just one more from the Australian Radiation Protection Agency:”
”Some military personnel involved in the 1991 Gulf War have complained of continuing stress-like symptoms for which no obvious cause has been found. These symptoms have at times been attributed to the use of depleted uranium in shells and other missiles, which are said to have caused toxic effects. Similar complaints have arisen from the more recent fighting in the Balkans, particularly the Kosovo conflict about a year ago.”
“Depleted uranium (DU) is natural uranium which is depleted in the rarer U-235 isotope (see below). It is a heavy metal and, in common with other heavy metals, it is chemically toxic. It is also slightly radioactive and there is therefore said to be a hypothetical possibility that it could give rise to a radiological hazard under some circumstances, e.g. if dispersed in finely divided form so that it is inhaled.”
“However, because of the latency period for the induction of cancer by radiation, it is not credible that any cases of radiation-induced cancer could yet be attributed to the Kosovo conflict. Furthermore, extensive studies have concluded that no radiological health hazard should be expected from exposure to depleted uranium.”
“You can see effects alright, but until you test for the causes, you have NO idea what the source for them may be. That takes detailed scientific research which has already been done and some of which I posted here. You have to run studies with exposures to DU on significant groups of animals, and again have a control group which are not exposed to DU”
“Then you limit exposure to all other possible toxicities. At the end of the study, you can make the link or not depending on your results. You don't just look at pathological health effects and DECIDE what YOU THINK causes it! Which is what you're trying to get us on this blog to buy off on. Surely you can't believe any of us are stupid enough to accept what you're saying as evidence?”
An additional comment:
“On the use of depleted uranium:
It's used because there is nothing else that is as good as DU for making tough armor on vehicles, and for making armor-piercing penetrator rounds to destroy enemy tanks and armored vehicles. It's NOT very radioactive... however, if you wind up breathing dust left over from a vehicle that got hit by a DU penetrator, it is very poisonous.
During the 1991 Gulf War, we blew up several Iraqi Army chemical weapons depots (several destroyed by airstrikes, one or more blown up by Combat Engineers who thought they were destroying conventional munitions). From the sources I've seen-- there was widespread very low-level exposure to nerve agents (Sarin *and* other types) and possibly to other agents as well (we know the Iraqi Army had a lot of blister agents, which are carcinogenic among other things)...
I'm not an expert but I can read, and every reliable medical source I've looked at (other than some DoD ones with a vested interested in shafting veterans) has commented that everything about Gulf War Syndrome is compatible with the expected effects of low-level exposure to chemical warfare agents.
