Gulf War veterans who fell ill due to radioactive depleted uranium

munitions fired by their own comrades insist,

" We were told nothing, " about the danger of radiation.

This echoes the complaint of the vast numbers of American soldiers

who contracted cancer after participating in the atmospheric

nuclear testing conducted from the late 1940s into the 1960s.

 

DU munitions are proliferating and being exported around the world

as conventional weapons. But what sort of weapons are they?

Why are so many US soldiers being exposed to DU particles?

The following articles will use photos of the Gulf War and its victims

to demonstrate the nature and effects of DU munitions.

Using Super-Heavy Nuclear Waste to Penetrate Tanks

 

What is DU?

Natural uranium ore from the mine goes through an enrichment

process designed to separate uranium 235 (U-235),

the isotope used for nuclear weapons and nuclear reactors,

from uranium 238 (U-238), a low-level radioactive by-product.

 

The highly radioactive isotope U-235 accounts for less than

1% of mined uranium; nearly all the rest is U-238.

The vast quantity of highly toxic metal (U-238) generated

by this process is called " depleted uranium " or " DU. "

 

DU emits primarily alpha radiation, and its half-life is thought

to be about the age of the Earth, or 4.5 billion years.

DU began accumulating in the US in the early 1940s while

the Manhattan Project was developing the first atomic bombs.

 

To date, more than 500 thousand tons have been produced,

and it continues to accumulate. At the uranium enrichment plant

in Paducah, Kentucky, and two other locations,

DU is packed into metal containers and stored outdoors.

 

DU is approximately 2.5 times denser than iron and 1.7 times

denser than lead. This high specific gravity means that,

as a projectile fired from a tank or aircraft, it carries enough

kinetic energy to blast through the tough armor of a tank.

Furthermore, the impact of this penetration generates extreme heat.

 

DU is pyrophoric, meaning that it burns on impact

and can set the target on fire. DU is easy to process

and endless quantities can be obtained free from

the Department of Energy (DOE), which controls DU

and considers its use in munitions to be

" utilization of waste material. "

 

The US military first noted these advantageous features of DU

in the 1960s, at the height of the Cold War. It began working

with such institutions as the Los Alamos National Laboratory

(New Mexico) to develop DU armor piercing shells for use

against the tanks of the former Soviet Union. Production began

in the 1970s and 1980s at a number of military munitions factories.

The weapons are tested at several firing ranges around the country.

The US military first used DU munitions in combat during the Gulf War,

firing penetrators from 120 and 105mm canons mounted on tanks.

Aircraft fired them from 25 or 30mm guns. The British fired DU rounds

from tanks only. During Operation Desert Storm (February 24 to 28, 1991),

at least 10,000 rounds of DU ammunition were fired from tanks,

and at least 940 thousand were fired from aircraft.

 

A DU projectile from a 120mm canon weighs

about 10.5 pounds (about 4.7 kilograms).

One from a 30mm gun weighs about 0.67 pounds (about 300 grams).

Because they burn on impact, 20 to 70% of their mass is vaporized

and diffuses into the air as uranium oxide particles.

 

It is said that when these uranium oxide particles are ingested

or inhaled, the combination of radiation and high chemical toxicity

can cause cancer and a wide variety of other ailments.

The US Nuclear Regulatory Commission (NRC)

has set the permissable internal dose of U-238

at 0.19 milligrams per day for the general public.

 

For employees at nuclear-related facilities, the limit is 2 milligrams.

Charred Bodies

Bodies of Iraqi soldiers abandoned in the desert.

Charred black by fires ignited by depleted uranium projectiles,

they look all too familiar to those of us

who have seen the A-bomb Memorial Museum in Hiroshima.
