Dear kr. Strauss:

4% the conclusion of Gperation CACTL, arewe
the
Gslirper
Iniwctek ari Bikind Atolls wes disestablished. At present, there exist
enly closed areas, wiich consist of the Jascone anit land areas of Eniwetok and Pikind Stolle ard the water areas within three wiles outside the
two stella,
In preparing for Gperation CASTLE a yectanenlar danger area was
established by the Atcnic Energy Cormissicn. After the BiAVS event it
wat necessary to enlarge this area es shown in Inclesure 2,
For Saas es 4% le reccmsenied that the danger area des<
cribed in Inecloeure 2 ani shom graphically in Inclosure 3 be satublished,
The propored area is oasier te describe and promilgete in writing then
the post-iAVG danger area and is therefcre lees subject to aisinterpretation. Further, the area te the east and northeast has beer gee #0
that it includes a grocter area in the direction of the moct
fallost pattern of large shots, Lastly, by reducing the size of the area
in the western sector most distant from Kwajalein, a more ccncontrated
search effort in the area of prebsble fallout will be pernitted.
It is reconmenied that the new danger ares de established as early
as practicable after the public amouncement concerning Cperation Ti0u1 MG,
ani that the effective date of the danger area be 20 April 1956, ten days
prior to the presently contemplated date for the first:event. The linits |
of the danrer area include air spece as well ae the surface aroa, There~ —
fore, appropriate aircraft control agencies should be included as addressees
when the
t is promipated,
It te requested that the Ataczic Enerry Comission initiate action te
establish the new danzer area, aa cutlined above.
