A PROGRAM FOR RADIOBIOLOGICAL SURVEYS AT THE ENIWETOK TEST SITE
Objective: To determine, quantitatively and qualitatively, the
presence of radiosotopes in the plants and animals at the test site,
in the northern Marshalis, eastern Carolines, and other islands as
far westward as the Palaus. From these determinationsestimates can
be made of the geographical diatribution of radioactive contami-
nants on land and in the ocean; of the radioactivity in foods
eaten by the natives; of radioactivity in tuna and other fish of
the commercial fishery; of the concentration of specific isotopes
by organisms and tissuea; of the biological fate of long-lived
isotopes (from pre-tast collections); of the vertical and horisontal diatribution of contaminants in the ocean; and of other
relationships.
Program: The types of surveys to be conducted, the areas to be
sampled and the kind of samples to be collected, are essentially
the same as for the Redwing Operation. The program, outlined in
brief, is as follows:
I.
II.
III.
Lagoon-atoll surveys - pre-test and post-test
A. Marshall and Caroline Islands
B. Palsu - Saipan area.
Standby surveys - during testing operation.
Oceanographic surveys - pre-test and post-test.
I. Lagoon-atoll surveys. - Surveys are to be made both before
and after the teating period. Collections will include plants
and animals from the island proper and from the reef, especially
food items, as well as water, plankton and goil. About 100 samples
from gach collecting area will be selected for quantitative measurement of radioactivity and from this group a few will be chosen for
analyses for specific isotopes. The remainder of the collection
will be kept in reserve for use in preparing additional samplee if
the analyses indicate that such are needed.
