Comment from Steven Dapra:
DU is alleged to have affected residents of the Balkans and of
Iraq; and is alleged to have affected soldiers serving in the Balkans and
in Iraq. No matter where it might be used in the future it will be alleged
to have affected residents of those areas or countries, and the soldiers
who serve there. That is, it is (or will be) alleged to affect any
population that is exposed to it. How does that make its health affects
unique? This 'uniqueness' of DU is nonsensical, as is the grandiose
question from David James Blaine Salsman about gentic damage during
prolonged conflict.

Comment (as above):
Your solitary voice shouldn't mean anything to anyone.

Comment (as above):
This is rich. James David etc. knows more about the 10 CFR 20
standard than do the parties who wrote it. Are you (JDBS) an HP or an
industrial hygienist? What are your academic credentials for petitioning
the NRC?

Comment (as above):
Yes, inquiring minds want to know.
