There are no differences between OSHA and NRC exposure limits for
Uranium-238(VI) compounds such as uranyl oxide and uranyl nitrate,
for example.  Both allow 0.2 mg/m^3.  The OSHA guidelines don't
mention the reproductive, developmental, immunological or
neurotoxicities at all.  United States Code, Title 42, Section
2114, requires the NRC to "protect the public health and safety
and the environment from radiological and non-radiological hazards"
of Uranium-238 produced as a byproduct of isotopic refinement.
