There is no possible protection from exposure to very fine
particles of depleted uranium through filtering of air.

- As a terrain contaminant: the dispersal of very fine particles
of depleted uranium will contaminate the terrain and deny access
to either side except at the risk of exposure. That includes
civilians and animals who may live there after the battle. The
half-life of depleted uranium – 4.5 billion years – leaves the
contaminated terrain radioactive forever.
Small particles less than 1 micron in diameter do not settle
from the air (see Attach. 3 – Chart “Characteristics of
Particles and Particle Dispersoids”) but become incorporated
into atmospheric dust (see Attach. 5 - Chart “Natural Aerosols”)
and are transported around the earth until they are removed
(“rainout”) by rain, pollution or snow3. Seasonal climate
change, agricultural activities, fires and other natural and
man-made disturbances will continue to remobilize particles in
the upper dust level contaminating terrains off the battlefield.
Weathering of larger particles of depleted uranium deposited on
the battlefield7 will contribute to concentrations of depleted
uranium fine and superfine particles in the air and upper dust
level.
Air monitors in Hungary8 and Greece during bombing in Kosovo and
Bosnia measured Uranium 238 carried by the wind from the
battlefields. Seasonal fluctuations of depleted uranium
particles in the air have been reported in Kuwait6.
- Water and food contamination: the depleted uranium dust will
cycle through the environment both on and off the battlefield
contaminating water supplies and food. Food grown in
contaminated areas will be transported to markets and
contaminate populations and areas far from the battlefields.
Wind, water, birds9 and animals who transport the depleted
uranium in their droppings, slowly contaminate wider and wider
areas.
- Internal contamination: inhalation of very fine depleted
uranium dust particles is extremely damaging to the respiratory
tract and will get into the blood stream where it is carried by
blood cells and contaminates tissues throughout the body. These
“hot particles”10 will continue to emit alpha and gamma
radiation (see Attach. 6 - photo “Hot particle in lung tissue”)
as they travel throughout the body or where they rest in tissue.
After the Uranium 238 nucleus decays, the radioactive daughter
product which forms (see Attach. 7) will continue to decay to
other isotopes as many as four times. This will increase the
level of radioactive exposure by magnitudes. Depleted uranium
particles lodged in tissue will decay and continue emitting
higher levels of radioactivity from daughter isotopes into the
surrounding tissues.
SYNERGISTIC EFFECTS: The health effects from exposure to a
combination of radiation, chemicals, and biological agents was
not addressed in this WW II memo. This is a critical issue on
the battlefield and should be considered in studies of Gulf War
Illness. The combination of radiation with heavy metals,
chemicals and biological toxins accelerate and increase the
adverse health effects of exposure. The effects are unknown
since very little research exists in this field11.
THIS IS AN ISSUE WHICH SHOULD BE CONSIDERED IN FUTURE CONFLICTS
SUCH AS THE PLANNED BOMBING OF IRAQ.
MEASUREMENTS OF DU IN TISSUES FROM 71 DEAD RESIDENTS OF BASRA:
Dr. Hari Sharma, a radiochemist living in Canada and member of
the Radiation and Public Health Project, has measured depleted
uranium levels in the tissues of 71 residents of Basra who died
after the Gulf War from cancers12. They were in the age range of
35-50 years. He found high concentrations of depleted uranium in
tissue samples from these individuals. The levels were about the
same throughout the tissues, suggesting that very fine particles
were transported in the blood and deposited or lodged throughout
the body.
WORLD TRADE CENTER AIR STUDIES:
Dr. Thomas Cahill, Emeritus Professor of Physics and Atmospheric
Sciences at the University of California at Davis, conducted an
independent study of the air around Ground Zero at the World
Trade Center after the 9/11 disaster13. Using very sophisticated
monitoring instruments14 which detect very fine and ultra fine
particles, Cahill and his group monitored the smoldering pile at
the WTC for 5 months following the disaster from one mile north
of the center. They measured concentrations of particles in six
size ranges from 2.5 microns to 0.09 microns13. They reported
the highest concentrations of very fine particles of metals ever
reported in the US13, and unprecedented numbers of very fine and
super fine particles13. This air monitoring study of the WTC
provided new information about very fine and superfine particles
which have rarely been studied. Burning metals and other
materials at high temperatures generate very large amounts of
very small particles. For this reason depleted uranium which has
burned is particularly hazardous.
The EPA has verified that depleted uranium was in the plane that
crashed into the Pentagon on 9/11 18,19 and that the crash site
was contaminated. Residents of New York City detected radiation
on hand held geiger counters at the WTC site. The EPA not only
failed to protect emergency response personnel at both sites,
but did not report or measure13 concentrations of very fine
particles at any of the 9/11 plane crash locations. These are
the most hazardous to health, and many personnel who worked at
the crash sites are now very ill.
Dr. Cahill also studied the Kuwaiti oil field fires following
the Gulf War.
ECRR: RELEASED JANUARY 30, 2003
A new report from the European Parliament has been released
“2003 Recommendations of the European Committee on Radiation
Risk: Health Effects of Ionising Radiation Exposure at Low Doses
for Radiation Protection Purposes” Regulators’ Edition:
Brussels, 2003 10. The report was written by 46 international
scientists and has over 550 references to epidemiological
studies which include nuclear site leukemias, Chernobyl infants,
minisatellite mutations, weapons fallout cancers, DU Gulf
Veterans, and Iraqi children.
The report concludes that the International Committee on
Radiation Protection (ICRP) determined international standards
for risk and dose effects from studies on A-bomb survivors which
were based on high dose, external, acute exposures. The ICRP
model only considered cancer as a health risk associated with
radiation exposure. The ICRP model, using “bathtub” chemistry,
“steam engine” physics, and deceptive reporting, produced faulty
and fraudulent estimates of risk and dose effects. Additionally,
because the ICRP model is based on acute, high dose, external
exposure it cannot accurately determine risks or dose response
for internal, chronic, isotopic exposures. For this reason, the
ICRP and ECRR models are mutually exclusive.
This new ECRR report based on epidemiological studies, concludes
that the health effects of low level radiation exposure have
been underestimated by the ICRP model by 100-1000 times. It also
includes other health effects due to radiation exposure from
global weapons fallout. In addition to cancer it estimates the
number of foetal deaths, infant mortality, and predicts “a 10%
loss of life quality integrated over all diseases and conditions
in those who were exposed over the period of global weapons
fallout”.
The committee concluded that underestimates of risk and dose
effects for depleted uranium exposure could be very great since
the effect at the cell level may be very different than other
types of radiation exposures. For this reason the health effects
of depleted uranium exposure in Gulf Veterans will be
investigated in depth by this committee and will be presented in
a new report.
Internal exposure to depleted uranium is a “novel” exposure to
an altered form of natural isotopes. The size, shape, surface
texture, density, chemical composition and other physical and
chemical factors of the particles greatly affect the health
impact and damage to the cells of any biological system from
depleted uranium exposure. Particle size may be the most
overlooked and one of the most important characteristics of
depleted uranium dust formed on the battlefield. After burning,
depleted uranium is altered both physically and chemically and
estimates of risk to health and dose effects cannot be based on
previous studies of naturally occurring uranium. In the Research
Report Summaries7 of depleted uranium studies done for the
military between 1974 and 1999, they clearly provide information
and concerns in these studies about the hazards of depleted
uranium both to health, exposure on the battlefield and damage
to the environment. This summary is well worth reading as it
provides a timeline of the military politicizing decisions on
the use of depleted uranium over 25 years. For example, in a
1980 Army report17:
This report provides an excellent history of the logic behind
the Army’s decision to use DU as a
kinetic energy, armored-piercing munition. DU’s final selection
over tungsten was based on
several reasons, including the lower initial cost of the
penetrator itself and its better overall
performance. DU and tungsten were rated even for
“producibility”. Tungsten had the advantage
for safety, environmental concerns, and deployment.
