Subject: [southnews] Depleted Uranium Toxicity in Afghanistan
Article: 129777
To: undisclosed-recipients:;
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.
