Is the 15% enrichment in reference to only soluble compounds of uranium?

I ask this because inhalation of Type-S materials, at enrichments much less
than 15%, including depleted, can produce large lung doses, without kidney
concerns.

I believe the EEOICPA work results in many lung cancer cases being
compensated when the only exposure is to insoluble compounds of low-enriched
(i.e., < 2%) uranium.  Such compensation is based solely on the radiation
detriment to the lung.

Ron Kathren's paper "Acute Toxicity of Uranium: "A Brief Review  with Special
Reference to Man" delivered today at the annual meeting of the Health Physics
Society in Portland, Oregon, (WAM-C.2) is must reading for all the DU
alarmists.

After almost 200 years of toxicological study, the best description is still
the one given by Gmelin in 1824: "a feeble poison". Ron's review of the
literature that includes human exposures to soluble forms of uranium reveals
that "no human is known to have died from exposure to uranium." Also, the
radioactivity of uranium is not relevant to toxicity unless it is at least
15% enriched in U-235.
