and the istands extending southwest from Japan to the archipelago of
Mansei Shoto.
Following KING, a less extensive survey limited to the
Marshalls, the eastern Carolines, and the Marianas was made (IPT#1).
Particulate fallout was collected on sticky “gum" paper at 111
worldwide stations including Honolulu, Guam, Ponape, Truk, and Midway.
The concentration of particulate in air was measured at Kwajalein, Guam,
Midway, and Honolulu.
At these locations air-filtering equipment was
turned on when the fallout cloud was known to be in the area.
Automatic
air-filtering stations, which were instrumented to begin operation when
the external gamma exposure reached 0.005 R/hr were located at Kusaie,
Ujelang, Bikini, Majuro, and Kwajalein.
The radiation level required to
start the equipment was not achieved in MIKE and the units were not reset
for KING.

Radsafe plans required an evacuation of all personnel from Enewetak
Atoll for the MIKE shot.
Early plans for evacuation of the atoll] during
KING were ultimately revised to evacuate only the islands north of Japtan
and maintain the capability to evacuate all personnel from Medren and
