Dear Bill:
seeing Roger McClellan's letter on the TTG reminds me that I have
not sent along my comments. I believe that your draft is quite
reasonable and I have only two comments.
In the discussion about contamination of urine samples with soil
I had considered that the soil activity would resemble worldwide
fallout and that such contamination would show up in the activity
ratios in the urine.
If the soil has the composition given in
Conard's report this would not be true and even using my values it
would not be very striking.
I think this possibility is definitely
wiped out.
I find it incredible that there are not reasonable estimates of
exposure to airborne plutonium for the present inhabitants. The
values in Table VII of Conard's paper are incredible to me since
they are only one fifth of what we find in New York.
Incidentally
T also disagree with the MPC in that table.
My figure would be
20 f£/m3 for insoluble plutonium in the population.
Sincerely,
{)
