Depleted Uranium Toxicity in Afghanistan
by Richard S. Ehrlich
ISLAMABAD, Pakistan — American warplanes are attacking
Afghanistan with depleted uranium weapons which could poison
combatants and civilians, especially children, according to U.S.
officials.
The possibility of radioactive dust storms sweeping across Afghanistan
and polluting rivers has meanwhile sparked fears in Pakistan.
"The radioactive dust released by the impact of these weapons can
easily get into the food chain and the water supply through the Kabul
River in Afghanistan and thus into Pakistan's Indus [River]," reported
Dawn newspaper.
"There are simply no contingency measures to brace people against
such a disastrous humanitarian fallout," Dawn added.
The narrow Kabul River cuts through the center of the heavily
bombed, mile-high Afghan capital and provides drinking water for the
people who dwell there.
After meandering east along the highway past Jalalabad and other
U.S. bomb targets, the Kabul River crosses into Pakistan and feeds
the Indus River, the country's biggest waterway. The Indus provides
much of the liquid nourishment to Pakistan's farms and people along its
route south to the Arabian Sea.
Pakistani Dr. Ali Rind warned Dawn's readers: "All flying bombs —
Tomahawk, JDAM etc. — are made of depleted uranium metal."
Many experts insist the dangers of depleted uranium are often
exaggerated.
Dr. Michael H. Repacholi of the World Health Organization, however,
said in a January report: "DU [deleted uranium] is released from fired
weapons in the form of small particles that may be inhaled, ingested or
remain in the environment."
Dr. Repacholi said, "For smaller particles, a larger fraction will deposit
in the lungs, where they may remain for months or years, unless they
dissolve. Very small amounts may be retained in the lymphatic system
for longer."
He added, "Breathing ultra-fine particles could lead to a theoretical
risk of cancer.
"In arid regions, most DU remains on the surface as dust. It is
dispersed in [non-arid] soil more easily, particularly in the areas of
higher rainfall."
Dr. Repacholi stressed, "Children rather than adults may be
considered to be more at risk of DU exposure when returning to
normal activities within a war zone through contaminated food and
water, since typical hand-to-mouth activity of inquisitive play could
lead to high DU ingestion from contaminated soil."
Depleted uranium is "used in several types
of munitions, but primarily
in two types: it's used in 120-millimeter tank rounds and it's used in
30-millimeter rounds fired by the A-10," Defense Department
spokesperson Kenneth H. Bacon told a newsconference in January.
The dreaded A-10 "Wart Hog" is a so-called a "tank killing" aircraft.
Every 30-millimeter round it fires has a 0.3-kilogram, depleted uranium
"penetrator" to bust through armor, according to military reports.
Depleted uranium is "primarily for anti-armor, and those are its main
uses," Mr. Bacon said.
"We obviously put out instructions about avoiding depleted uranium
dust," he added.
"Troops are instructed to wear masks if they're around what they
consider to be atomized or particle-ized depleted uranium — that is if
rounds have struck tanks, there could be depleted uranium dust
around.
"So if they were working around an [enemy] tank that had been
disabled by a depleted uranium round, they would be instructed to
wear some sort of mask to prevent breathing in particles," Mr. Bacon
said.
"All our studies show that in cases where there is dust, it [depleted
uranium] is washed away and nullified by the first heavy rain.
"But there aren't a lot of heavy rains in the desert, so obviously, when
we were advising our soldiers how to deal with depleted uranium
damage, or damaged vehicles in the desert, we were careful to point
out that they should wear masks."
Depleted uranium is described as uranium that is 40 percent less
radioactive than natural uranium, though it retains identical chemical
properties.
Natural uranium is found in everyday air, water and soil and, as a
result, is also in each person's body.
Depleted uranium, however, has a half-life of 4.5 billion years.
In 1998, the Pentagon noted: "Depleted uranium is the most effective
material for [military] uses because of its high density and the metallic
properties that allow it to 'self-sharpen' as it penetrates armor.
"Armor containing depleted uranium is very effective at blunting
anti-tank weapons," the Pentagon added.
"The major health concerns about DU relate to its chemical properties
as a heavy metal rather than to its radioactivity, which is very low."
Shrapnel from a depleted uranium weapon's explosion can pepper a
victim's body much like a shotgun blast.
If the shrapnel remains embedded in a person, then the radiation "isn't
eliminated," an expert said at a Defense Department briefing.
"By accumulation, is the [radioactive] dose increasing with time? Yes,
it is," the expert added.
Dr. Ross Anthony, from the Rand Corporation, told the Defense
Department briefing, "The kidney is the part that is the most
susceptible."
In experiments with animals, however, "there seem to be no real highly
negative effects until you get a very, very high dose," Dr. Anthony
said.
In 1999, Steve Fetter and Frank von Hippel wrote in the Bulletin of the
Atomic Scientists: "Radiation doses for soldiers with embedded
fragments of depleted uranium may be troublesome.
"Apart from radiation, however, the risks related to the heavy-metal
toxicity of uranium inhaled and ingested by soldiers in direct and
unprotected contact with vehicles struck with DU munitions could be
significant.
"Primarily at risk are those who were in vehicles when they were
struck, or their rescuers, as well as those who worked for extended
periods in cleanup efforts inside the vehicles without adequate
respiratory protection," they added.
"Very prolonged exposure to high concentrations of depleted uranium
is required to give radiation doses significantly above [normal]
background" levels.
"Pieces and particles of depleted uranium lying about would be
sources of most of the external radiation dose, which would come
primarily from penetrating gamma rays.
"Inhalation of DU-contaminated dust — either directly or after
resuspension [in the air] — would be the source of most of the internal
dose, which would be primarily from very short-range alpha particles."
Referring to desert dust storms, the bulletin said, "The ground the
DU-contaminated plumes passed over would be coated with a thin
layer of DU dust, some of which would be later kicked up by wind and
human activity.
"The munitions could deposit a layer of [depleted uranium] dust on
crops that could be eaten directly by humans or by animals later
consumed by humans.
"However, rough estimates suggest that the cancer risk from
consumption of contaminated produce would be less than from
inhalation."
As a result of the U.S.-Gulf War, "the number of Iraqi soldiers with
embedded DU fragments could be in the thousands," the bulletin said.
"Natural curiosity may also lead children and other passersby to
investigate the interiors of destroyed tanks and other vehicles...which
would subject them to danger from DU dust," it warned.
"Such vehicles should be made inaccessible, perhaps by being buried
and then pumped full of concrete."
Critics have expressed concern over depleted uranium contamination
on battlefields which do not receive environmental clean-ups.
Some critics claimed birth defects among babies born in Iraq after the
Gulf War — including headless victims and others with deformed
limbs — may be linked to the U.S. use of depleted uranium.

Prima i Talebani dopo l'uranio? Dalla padella nella brace?
Non si ha ancora una certezza ma se questo fosse vero sarebbe gravissimo, il bilancio dei casi di cancro ai bambini le malformazioni e tutto quello che già si conosce altro dolore sul dolore, un problema sanitario enorme, basti pensare che il fiume per quelle popolazioni civili è una risorsa a tutti i livelli. Se tutto ciò fosse vero oggi saranno costretti a bere l'acqua radioattiva e ad respirare gli ossidi dispersi nell'aria.
