should result in a large improvement in this
situation.
In the mean-time we should continue
with the program as outlined, albeit keeping
our eyes open for significant bits of data that
could result in useful adjustments.
(This requires that someone, presumably Livermore, be
on top of the situation and continually follow
the impact of new data.)
I do not believe that it would be useful
to provide detailed page by page comments be-
cause much of what is in the report is similar
to what we have heard recently.
Thus, the new
list is not dissimilar to that given in our
last meeting and I assume that LLL can get together with Bramlett and iron out the differ-
ences.
I do have some problems with Bramlett's
use of the dose distribution factor but this
is a detail.
It may also be noted that the
committee noted the problem with the LLL amer-
icium bone calculation following inhalation
and this has been corrected by Livermore.
I would suggest that the committee focus
on appropriate metabolic parameters to be used
in such calculations.
This would include such
items as lung weight, bone weight, inhalation
rate, and similar values.
We have, I believe,
already assumed americium to be Class W although
some review of this may be useful.
Such a set
of parameters will allow better intercomparison
between individual calculations and will avoid
potential future controversy.
I would also
suggest that some attention be place on the
other nuclides (°°Sr and !3’Cs) in the program
at Livermore and in the Committee deliberations
with the goal of providing dose estimates that
will place a finite bound on the length of time
before each island can be used.
