Dear Joe,
.
In order tc propose Eny meaningful sampling program that cculd be
conducted in conjunction with the proposed multi-Atoll aerial survey,
we feel we first require much nure iriformtion about the ship that is
proposed for use; proposed access met!~odsto the islands; availability
of small boats; type of qear we c~n take and plan to nove about cn ths
islands for either marine or-terrestrial sampling which, in turn, greatly
depends on the types of support the ship is willing to provide the
scientific parties; the current estimates cf tim to be spent at each
Atoll which will determine the amount of work we can acccriplishand the
availability of funds which will be required to proceed with any proposed
analytical phase of the program.

If a vessel can enter the lagoons a marine collection program
should be considered,.toestimate dose from the marine foodchain.
Either a sufficient quantitycf the represent-ativeedible sp&cies be
collected for analysis or fewer fish and representative water sanples
collected to both cofiputeand co~pare concentration factors. These
values can then be used to predict average conceiitraticns in the mrine
speeies at the remaining Atolls. All sa:nplesshoula only be analyzed
for 137Cs, ‘OSr and plutcnium rzdicnucljdes by wt chemical methods.
These are the prli:cipaldose contributing radicnuclides in the r~arice
