Barnes, Jo Jane Giacomini and/or Burt Friesen participate in the planning
of the experiment and analysis of the results.
Since DNA wants advise
on plowing, this experiment should be completed as soon as possible.
Resuspension
Data on resuspension of Pu and Am contaminated soil particles at
Eniwetok are insufficient to evaluate the potential inhalation dose to
children playing on the ground or adults working in agricultural
areas.
The Advisory Group urges that an effort be made to obtain resuspension
If it does exist, the
data of this nature unless it already exists.
Advisory Group welcomes an opportunity to review the data.
. Averaging the Soil Concentrations Over Entire Islands
The committee considered the possibility of using island average
concentrations to determine how much soil should be removed, to assess
cleanup performance and to calculate doses.
The Advisory Group sees no
compelting reason to alter the previously agreed upon plan to consider
each 1/4 or 1/2 hectare separtely for cleanup.
The subject of averaging
arose from Dr. Robison's discussion of the dose assessment work where
"average soil concentrations" were used.
The Advisory Group believe the
concept of averaging should be restricted to dose estimates and, even
in this case, should be used with great care.
There are a number of
methods that could be used for basing dose assessments on actual soil
data:
1.
Compute the dose on the basis of highest estimated soil
concentration for any unit (of 1/4 or 1/2 hectare size) on
the island.
This method could result in a very conservative
