...The pyrophoric effect of depleted uranium, which spontaneously burns when heated to 170 C (once it is fired) and on impact, effectively forms very large numbers of extremely fine (0.1 micron) and submicroscopic particles as small as 0.001 micron or 10 Ångstroms (see Attach. 3 - Chart "Characteristics of Particles and Particle Dispersoids") as described in the memo. Particles in this size range behave like a gas when inhaled, disperse in the lungs to the blood lung barrier where the white blood cells (greater than 7microns in diameter) engulf the tiny particles of depleted uranium and carry them throughout the body. Once these particles have been engulfed by blood cells or lodged in tissues, they may not be detectable in the urine. Contaminated personnel will take the depleted uranium home, deposited in tissues throughout their bodies. There is no known treatment for exposure...
...It will permeate a gas mask filter: particles in the 0.1 micron range will penetrate even a HEPA filter (High Efficiency Particulate Airfilter - see Attach. 4 - HEPA chart) in large numbers. The filters in gas masks issued to military personnel are much less efficient than HEPA filters...
...The gas masks issued to military personnel now deployed to the Gulf Region are defective and do not provide even a minimum of protection to personnel...
...Air filters in gas masks also fail as they are wetted by moisture from breathing or are used in the rain...
...There is no possible protection from exposure to very fine particles of depleted uranium through filtering of air...
...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...
