Uranium is an element which, like many others, is
all over around us. However, natural
concentration is 0.5-5gr. per 1 ton of soil. If there is more than 0.1% of it,
than it is possible to open a mine since uranium is basic nuclear fuel. Natural
Uranium has three shapes or isotopes: 234U, 235U and 238U,
that are chemically the same but differ by their nuclear characteristics.
Uranium is radioactive element and it emits nuclear rays that are result of its
decay. There are three basic types of radiation, Alpha, Beta and Gamma that are
not similar nor are of the same threat to living nature. While U235 ( the one
that is used as a fuel for commercial purposes ) emits mostly Gamma rays,
Uranium U238 emits almost only Alpha ones. Depleted Uranium is uranium that
consists the least quantities of U235 ( below 1% ) and has most of U238 ( some 99% ). DU is, in fact, nuclear
waste, residuum of uranium used in Nuclear Plants. There is about 1 million
tons of it all over the world. Alpha rays that are emitted from depleted
uranium are of the short range ( only several millimeters from the particle )
but they are 20 times more destructing for the living tissues than other
nuclear rays. DU is very dangerous
because it is highly radioactive and toxic!
Ammunition with DU is used to destroy enemy’s armed
vehicles and shelters. It is made in various calibers – from 7.6 mm up to over
120 mm. Major part of this ammunition is sting or penetrator made entirely from
alloy with most of depleted uranium. Formal reason why DU is used is covered by
explanation that DU is the densest existing material (1.7 time more dense than
lead is), thus making rounds of it, one should get the most penetrable and
efficient weapon. This cynical explanation hides the fact that the countries,
producers of such ammunition, dispose huge quantities of their nuclear waste
introducing such a new type of nuclear war. Up to air strikes in Yugoslavia,
most used caliber was of 30 mm that is fired from guns mounted on planes, A-10,
AV-8B HARRIER or on tanks. Rounds of this caliber could penetrate steel of 6-7
cm wide. The ammunition of this size
contains 292 gr of DU.
In the Gulf war, more than 940,000 pcs of DU rounds has been fired, mostly
caliber 30mm and 14,000 pcs of calibers 105mm and 120mm. Overall quantities of
DU dispersed over Iraq are estimated on 320 tons. Data from Bosnian war are not
completed yet. Defence US Department and NATO officials admited use of DU ammunition
in Yugoslavian war. Detailed and precise information are not disclosed and are
still in posesion of NATO. However, Russian estinmations are that about 30
tonns were spread over this territory, mostry in Kosovo. Appart from mentioned
DU ammunition, there are indication that DU has been used in cruise missiles
and laser bombs, as well.
NATO refused to relese information on types, quantites, and places where DU
ammunitionje have been used. However, all KFOR soldiers in Kosovo are supplied
with radiological protection suits and are obliged to use all protection
mesures when in vicinity of places suspected (?!) to be hit by DU rounds or
near by objects that were destruct by bombs which »might have had« DU. Soldiers
are also regulary examined on possible contamination. Why?
Apart from purely
mechanical, DU ammunition has extremely dangerous radiological effect on human
as well as on environment in all. To learn this, it is necessary to know what
happens with the sting (penetrator) once it hits solid target, such as tank or
concrete structure is. The penetrator disrupts into:
Large shrapnel ( tenths of
grams )
Small parts ( grams)
Large particles ( over 10
micrometers ) and
Aerosolized particles (
uranium dust ) produced by burning
First three types of
particles are solid depleted uranium itself and, being relatively heavy, drop
in the close area ( 10 meters ) around impact spot. These particles, apart
being radioactive are also very toxic and may intensively react with fluids
around them - primarily water - contaminating such surface and underground
waters as well as soil itself.
In case of direct hit, the
high temperatures, of about 1200 oC,
are developed on the impact spot. Since uranium burns on 700 oC, most
of the penetrator (50-70%) combusts into uranium dioxide and uranium trioxide.
One hundred grams of uranium burns out into about 1,000 grams of fine, black
uranium dust. Inhaling just 0.002 grams might be fatal to human health.
Because of immediate cooling, fine uranium
mist is formed. Particles do not exceed 2.5 micrometers in diameter and
essentially have ceramic form, in other words, they are not soluble and stay
unchanged for good. Most of the particles fall on the ground in the closest
surrounding of the impact spot. In the distances that exceed 200 m, their
number is smaller although they may be detected even tenths of kilometers from
the impact spot because, in respect to their very small size, they can be
easily moved by wind. This only underlines high danger of contamination which
can be spread in very wide areas.
Dangerous effect of exposure
to depleted uranium could be inducted by outside or inside radiation. Outside
radiation is significant when the whole sting or its parts are close to humans.
If such parts are in direct contact to skin, because of the alpha and beta
radiation, it could be burned. Such cases are rare and could be avoided
Inside radiation is, however,
difficult to avoid and is much more dangerous. Basic threat appears when
inhaling or congesting DU particles.
Once in taken, uranium endangers all tissues it encounters, primarily lungs,
liver, kidneys but also other organs, such as spinal content tissue, etc.
Inhaled uranium dust has soluble and insoluble particles. Soluble particles are
toxic and they poison the organism while the insoluble parts are more dangerous
because of their radioactivity. Increased risk to cancer is about 5% per
sievert what means that someone that has been exposed to DU close to impact
spot might have increased risk to cancer from 20% upwards.
Tiny uranium parts penetrate
soil into underground water contaminating, such, the whole food chain on a
long-term basis. DU half decay time is 4.5 billion years what practically means
that, once spread, it stays in our environment forever. The most endangered are
soldiers and individuals that were close to impact spots at very attack. It is
not excluded that such persons might have inhaled hundreds of grams of DU. It
is quite possible that people working on mending damages after bombing, inhale
additional quantities of DU particles. This because dust is disturbed by
people, vehicles or wind. Equivalent doses are, in such cases, less (tenths of
micro sieverts ) but not less dangerous.
If the target is missed, just
a little percent of DU will become insoluble dust. Solid uranium will be on the
surface or under it where it will react with water. Depending on geological
situation, there is high risk on contamination of underground water. Detailed
examinations must be exercised for every particular case.
Uranium stings from 30mm DU ammunitions have shape of cigar, about 30 cm of
lenght. They could be slightly deformed from impact or broken in to several
pieces. Sometimes, at one end, parts of aluminnium holder might be found. Those
needles or stings are essentialy made of solid DU. Since just 25% of DU rounds
hit the target, many parts of this rounds could be found all over the target
area, aither on the soil surface or buried under the surface.

APPROPRIATE TESTS !
·
INFORM AUTHORITIES ABOUT THE PLACE, TIME AND WAY
YOU WERE EXPOSED TO THE CONTAMINATION !
Šta tražiti:
·
INSIST TO GET ALL RELEVANT INFORMATION ON
CONTAMINATION IN YOUR AREA. IN RESPECT TO THE CURENT LOW ON PROTECTION AGAINS
IONIZING RADIATION AND INSTRUCTIONS FOR EXTREEM SITUATIONS, AUTHORITIES ARE
OBLIGED TO DISCLOSE AND PUBLISH ALL SUCH DATA !
·
INSIST ON DETAILED AND ACCURATE MEASUREMENTS OF
NUCLEAR POLLUTION IN YOUR AREA. IN THIS MANNER YOU WILL BE SURE ON LEVEL OF
CONTAMINATION AND WHAT IS A REAL DANGER. INSIST THAT THE INFORMATION MUST BE
PUBLIC AND ACCESSIBLE TO ANYONE ON
REQUEST !
There are two types of measurements: examination of terrain in aim to fix
the location and measurements of uranium contents in soil, water, food, air,
plants and animals. There are several methods: gamma spectrometry, (most common
and rather simple one), alpha spectrometry, alpha radiometry, nutron activation
analysys (most acurate), mass spectroscopy and others. ALPHA RADIATION CANNOT BE DETECTED WITH GAIGER COUNTER!
WARNING!
Inhalation of DU dust particles has been associated with long-term health
effects, including cancers, birth effects, neurological damage, damage kineys
and a damaged immune system. These effects may not become apparent untill a few
years after exposure.
