The ship's operational gear functioned properly except for the Kercules
fire end flushing pump which ren out of fuel at 1640 on T-day due to a fuel
leak,
At 1845 the pump was put back on the line end it failed again at 0345
for the same reason,
While this pump was inoperative, the volume and pressure
of the washdown water was reduced considerably.
The cyclic air sampler showed no internal airborne activity at any time.
Externally, there was no airborne hazard detected after 0300 on T+.
RADSAFE SUPPORT
Ship Support
The number of RadSafe personnel on tosrd the LST-~611 and the YAG's 39
and 40 were the same as for previous events.
The YAG-39 received the heaviest fellout of the three ships involved.
Excellent RadSafe cooperation on the part of the ship's personnel kept the
spread of contamination to the ship's interior to a minimum.
personnel dosage received was 1.75 r.
700 mr.
The maximum
The average exposure was approximately
Ten cases of skin contemination occurred with a maximum detected of
40 mrep/hr including 2 mr/hr.
In all cases the contamination was success-
fully reduced to an acceptable level by soap and weter scrubtings.
The
maximum air contamination measured inside the shir was 1 x 107"nc/ec.
Fall-
out was detected at 0745 with a peak radiation level of 41 rfhr occurring at
1100 on T-day.
Fallout was complete at 1200 on T-day.
By T+6, the YAG~39
had been decontaminated to a level that would permit return to the ZI with
an estimated average crew rediation dosace of 1.5 r and would permit access
to the aft portion of the ship without protective clothing.
Fallout on the YAG-40 started et 1015 on T-day and reached a maximum
of 7.5 rfhr at the forward starboard TIR at 1200.
Thirteen ceses of skin
contamination occurred with a maximum of approximately 20 mr/hr.
