ENCLOSURE IV
SPECIAL ASSISTANT TO THE SECRETARY OF STATE
WASHINGTON
February 13, 1956
MEMORANDUM FOR
Mr. John A. Hall,
Atomic Energy Commission.
I refer to
elegram 1839 dated February 9 from the Embassy
at Tokyo reporting on the rising Japanese concern over the
proposed tests in the Pacific and suggesting certain things
that might be done to better the situation.
We should appreciate receiving on an urgent basis the AEC's
comments on the following actions that might be taken.
In this
connection Admiral Hanlon recently briefed a group of officers
in the Department on REDWING and some of the following were
developed as a result of this briefing.
1.
Imediately inform the Japanese of the proposed marine
biological survey that will be conducted during and after
the test series and offer to make available to them the
analyses of the data obtained.
In addition ask the Japanese
to join us in a joint survey of the waters outside the
danger area. Further let us consider what might be done
through collaboration of the International North Pacific
Fisheries Commission (U.S., Canada, and Japan).
2. Immediately inform the Japanese and also the Trus-
teeship Council of the details of the safety precautions that
we plan to take during the serles.
This would include
information on improved methods of weather forecasting,
location of Radiation Safety monitors on various atolls, air
and surface searches to assure that no unsuspecting mariner
is within the danger area, ete.
3. Increase the exchange of information on radiation
standards with appropr’:.te Japanese.
Since there has
already been an exchange of this type of information, it
might be advisable only to encourage the Japanese to
publicize this point. Should the Japanese so request it, we
might send another team to Tokyo similar to the one sent
in November 1954.
4, Immediately inform the Japanese on a confidential
basis of the fact that the danger area will be continued
until at least August in order that fishing groups can
make their forward plans accordingly.
Unless something
is said on this point the Japanese may conjecture that
the period of the establishment may not exceed that of
CASTLE with the result that plans would have to be changed.
