[ RadSafe ] DU not toxicologically identical to non D-U

While I can see an argument that DU is LESS toxic, radiologically, than
uranium that has not had the shortest half-life, and thus highest
specific activity, isotopes removed, I assume that is not what you wish
to imply. If you have an argument for how something with a lower
activity (by weight or per atom) is more toxic, I would be interested.
If you are saying that the chemical properties of U238 are sufficiently
different from those of U235 and U234 as to be detectable in the way
organisms are affected, I would like to see the model and the evidence.
I do, however, see a problem with you citing evidence, as your record of
citing relevant items that actually support your position is not good.

That is not consistent with the translocation graph shown in the
Gmelin Handbook of Inorganic Chemistry, 8th Edition, English
translation (Springer-Verlag, 1982), Title U -- Uranium, Supplemental
Volume A7 -- Biology, Section 3 -- Metabolism: Absorption, page 305,
Figure 3-1, "Retention and translocation of inhaled uranyl nitrate,"
from J.E. Ballou, R.A. Gies, and N.A. Wagman in BNWL-2500, Part 1, pp.
If I owe Bob Cherry an apology for not knowing about genotoxicity when
he made statements to federal officials on the health aspects of
uranium fume inhalation, or for getting his title wrong, then I
apologize. I remain of the opinion that a more appropriate title
would involve a Quantico detainee number for decades followed by
"Defendant" in a medical expense loss recovery class action suit, and
I appreciate all the work the military does to defend my right to
express such opinions.
