RE: Request for Info on DU Munitions: Useful(?) Information

Michael et al:

I think the key word here is "radiologically."  Look at the dose conversion
factors for Class-Y uranium in FGR No. 11, for example, and you'll see that
the lung is the most limiting dose receptor.  Just as you've stated, the
kidney is the primary target of the chemical toxicity of uranium.

BTW, thanks to the fellow GT grad that sent us "out here in the sticks" a
copy of the new HP Manual for Good Practices at Uranium Facilities.

Am I missing something?  I only have ICRP 30 in front of me right now, but
the only retention functions that I see are for R(bone), R(kidney), and
R(other).  The lung is not a critical organ for U.  Uranium is a
nephrotoxin.

In fact, the DOE STD that is cited below discusses both the ICRP 30 and 54
retention models, citing the above critical organs and goes on to state:

"The kidney is the primary target of the chemical toxicity of uranium." (pg.
5-28).

In light of all of the banter about DU, I felt compelled to provide some
widely accepted useful information. The vast majority is taken from
DOE-STD-1136-2000 ....

Radiologically, the target organ is the lungs, followed by the bone surfaces
(not the kidneys).
