Apparently not.  According to Palatnik, et al. (1970) in "Volume
Condensation of Metal Vapors" Powder Metallurgy and Metal Ceramics,
vol. 9(4), pp. 335-7, the condensation zone of heat-volatilized metal
vapors has a radius on the order of a few centimeters at most, and the
gas molecules which escape that zone remain as such until they have an
opportunity to plate out on the ground, dust, a wall, a plant, etc. --
or someone's lung.

When you have so-called authorities like Dr. Raabe claiming that "all"
of the vapor condenses "instantaneously," and completely unable to
substantiate those claims with empirical mass measurements, is that
ethically any different than Colonel Daxon claiming that Dr. Kang's
unpublished reports indicated that U.S. troops' children's birth
defect rates decreased, when they have actually been steeply
increasing?

Apparently Colonel Cherry misplaced his copy of the Department of
Energy's safety handbook DOE-HDBK-3010-94, "Airborne Release
Fractions/Rates and Respirable Fractions for Nonreactor Facilities"
all the time he was supposed to be responsible for determination of
depleted uranium weapons safety, and never read section 2.2, "Vapors
(Condensible Gasses)" which clearly states, "transport losses must be
substantiated for the specific configurations associated with an
event."

The only proponent of depleted uranium weapons who has ever called for
such substantiation is Dr. Johnson.

Colonel Cherry, will you join him, or do you prefer to remain in the dark?

Sincerely,
James
