This would be a very costly procedure! I cannot imagine that somebody would

do it and what it should be good for.



I know the term "uranium with its natural isotopic composition" as opposed

to enriched or depleted uranium. I have also a uranium compound in a bottle

on which' label there is stated, that "the isotopic composition may deviate

from the natural one". I have never heard the term "normal uranium". Then

there should exist also an "abnormal" one....
