2.2.2-The[ Yuma
leoviee f{red on Aomon, produced_contamina-~
tion only in the 5 ot xrea on
the island. Significant amounts of
ontamination were found. Figure 2.2 shows the H+4 hr survey results.
Because of this
“Ycontamination, added precautions were taken In
processing all persons "yeturning from recovery operations. The tower site
for thef Kickapoo
device on Aomon was not matertally affected, however.
2.2.3—The _Erte_ievice, fired on Runit in the vicinity of the airstrip,
produced heavy contamination only on the shot island. Survey results at H+4
hr are shown tn Fig. 2.3, Islands north of Runit in the atoll were but slightly
contaminated and no Interference with preparations for other shots resulted.
Bulldozing operations were carried out on Runit in the Blackfoot Jtower area in
order to reduce exposures to an acceptable level for personnel requiring accese to this are
2.2.4—The SeminoleJ produced extremely heavy contamination on the Tei-
tefripucchi-Bogon complex,
Survey results are shown in Fig. 2.4.
Certain
recovery missions requiring entry on the south end of Teiteiripucchi were
held up for approximately two days. Entry Into the bunker on Bogon by
helicopter was not materially affected.
2.2.5—Heavy contamination from the Backtoot J shet, fired on central Runit,
was limited primarily to the shot island.
However, the photo tower on Mack
was highly contaminated from the fall-out. The contamination on Mack wes
reduced to some extent by local rain showers; in general, this contamination
complicated preparations for other shots, since it made full protective clotning mandatory for any operations in the tower. Survey results at H+4 hr
are shown inFig. 2.5.
2.2.6—
Kickapoo
device was fired on Aomon and resulted
only in heavy local
contamination. Tower sites for the| Mohawk [device on
Eberiru and thea Inca|device on Rujoru were not materially affected. Survey
results are shown in Fig. 2.6. Significant [~
contamination
resulted from the shot, requiring the establishment of a special check point
and personnel-decontamination facilities on the south end of Aomon in order
to facilitate recovery operations.
During these operations extreme precau-
tions were necessary, and certain of the operations required the use of supplied-air breathing apparatus by welders, as for example, when cutting torches
were used on pipe
sections.
2.2.7— The Osage| device, air-dropped and detonated at 70C ft over
central Runit, produced no significant contamination.
The pre-entry survey
showed that no detailed rnurvey was required and that recovery operations
could proceed without difficulty.
22.8-Thof nealdove, fired on Rujoru, produced heavy local contam!nation on the she* fsland, Contamination on the adjacent island of Eberizru
