Objectives
The objectives of this project include the collection
of fall-out samples for the documentation of the physical
characteristics as a function of time and distance, and to provide samples for chemical and radio-chemical analysis for Project
2.6D.
;
Instrumentation
The following seventeen stationmswere instrumented with
two intermittent fall-out collectors each: Yurochi, Uorikku,
Romirikku, Aomoen, Bikini, Rochikarai, Enyu, Airukiiji, Eninman,
Eniirikku, Rukoji, Chieerete, Arriikan, Ourukaen, Bokoaetokutoku,
Bokororyuru, and Bokobyaadaa.
One instrument at each station was
set to collect twenty-four samples in 5-minute intervals; the other
collector to collect twenty-four samples in 30-minute intervals.
Recovery
Recovery was poor due to the following reasons: Station
deterioration, the result of the sixteen day delay between station
&
activation Po damage to instruments caused by
—
the tidal wave. “Daily field meintenance was performed on the
collectors, however, the uncertainty of the firing date precluded
a thorough job.
Results
Approximately fifty percent of the collectors functioned
