Yable 3.2 and Table 3.3 List the data for SUNI.
Sote that for
this event & inch steel pipe stations were installed at four 210
series stations.
and 210.36',
These vere designated 210.23', 210.27", 210.30’
The rate device at 210.27' became wedged in the
seiee
station and failed to drop. The initial readings were obliterated
by the residual. The
of 210.30' was broken hy the shock caus-
ing the instruments to
of the total gamma expos
1.44 seconds. A third
mechanian yielded only
immediately. About eix percent (1070 r)
of 16,000 r arrived before shock at
device at 210.34' without a dropping
exposure information.
A mechanioal drop device installed in a water fiiled steel pipe
at 210.23' functioned properly. All of the films which dropped read
leas than one roentgen since the initial exposure was megligidise.

Tables 3.4 and 3.5 contain initial data.
‘The difference
between the fila and quarts fiber exposures at Station 212.03 is
not fully understood. At Btation 212.05 the 10 r thermal and
blast exposures are the result of ZUNI residual contamination.
Film indicates about three roentgens initial exposure and quarts fiber
dosimeters indicate about 4.5 r.
The switches in the mechanical
Grop Gevices at 213.02, 213.03, and 213.0% functioned but the
dosimeters 414 mot fall below the surface because of a constriction
in the pipes.
Results from the quart: fiber exposure versus time devices are
shown in Table 3.6 and Figure 3.7.
The rate device at Station 211.01 did mot drop, so it was
necessary to subtract the re:idual exposure of 500 r. It vas
assumed that the 48 r arriving after 15 seconds was residual, the
shielding being ony 90 percent effective. At Station 212.
the device operated in reverse, yielding only total residual in-
formation. At Station 211.03 the exposure was small and could not
be resolved properly.

Fable 3.7 lists installation and recovery information and
exposures from residual stations.
Information from Project. 2.2
indicates that Stations 210.23 to 210.41 received about 1 roentgen
of fallout from FLATHEAD shot.
The remainder of exposure at
these stations was from Shot ZUNI.
