[ RadSafe ] Urine tests for uranium exposure typing?

[James Salsman]

Is there anyone who believes that the isotopes of uranium 
do not translocate at different rates?

Why doesn't the fact that they do mean that any attempt to 
determine the original isotopes of exposure from urine are 
likely to be inaccurate?

Sincerely,
James Salsman

P.S. To Steve:  The Khan et al. (2001) ratios were 1.8 for 
offspring of males, and 2.8 for offspring of females, not 
1.9 and 2.9 -- do you know something I don't?
