Dr. H. B. Keller, UCRL, had given special permission-to exceed the 200 mr.
maximum recovery dosage ana,
if necessary, get up to 500 mr., as this was an
emergency recovery program and the instruments involved had to be retrieved
that day before another scheduled event took place.
A recovery was made in one station with a 15 to 20 minute exposure in a 250
mr/hr area. At the second station only three legs of a four-way-bridle Cargo
Net containing the instruments could be secured, resulting in a cave-in of the
sana bags anda neccessitating a longer stay in the area than anticipated. The
party stayed approximately one-half hour in a 2,000 mr/hr field.
The TU-6 Monitor advised on two occasions that the party should leave the
area, but as they were progressing with the recovery satisfactorily, it was
decicea py Mr.
to complete the mission.
The material that was placed in Mr. Mullin's Dukw was reading only 60 mr/hr
ana Mr.
left the Dukw immediately upon entering the T-boat for the
return trip to Nan.
It was further reported hv Mr. W
Operator (apparently Mr. . .
she TU-6 Monitor, that the Dukw
, although it was difficult to identify the men
because they were deckedout in complete protective clothing including
respirators) could have received a higher dosage due to having his Dukw parked
aown-wind from where the men were digging. It was the only place the Dukw
coulda be parked so the driver could be handy to receive the delivery from the
Cherry-picker.
It was also reported that with every shovelfull of dirt
raised, the needle on the Radiac instrument would advance considerably.
