[ RadSafe ] industrial hygiene of radionuclides

[James Salsman]

Tom,

Thanks for recommending the Radiological Health Handbook.  Under
U-238, is there an account of the teratogenic genotoxicity?

I ask because 10 US CFR 20 has been showing the toxicity of soluble
compounds as less than insoluble, which strongly suggests that only
the radiological toxicity and not the chemical genotoxicity has been
taken into account. (Pending U.S. petition NRC-PRM-20-26.)

We were just discussing some reproductive toxicity work from 1953:
Voegtlin and Hodge, eds., "Pharmacology and Toxicology of
Uranium Compounds" -- at least three volumes.  I would like to see
that one.  Some of its reports seem to be enjoying a contemporary
series of replications, e.g.:
  http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2137136

Why aren't they karyotyping the white blood, sperm, and egg cells of
those rats?  That's where the action is.  I guess since rats only live
for about 5 years, tops, maybe it's not a substantial enough amount to
be significant?  It depends on the dose, of course.

Still, there's no excuse for not quantifying the reproductive toxicity
before writing about it with the certainty that we were hearing from
the military and their lapdog contractors 1972-2004.
