Operations:
Sampling devices on F-84, WB-29, and B~-36 airdraft were
used to obtain nuclear debris samples close in to the detomations.
Long-range calibration samples were also collected by WB-29
aircraft.
Aircraft generally did not enter the cloud until 2 hours affter burst;
the clouds were followed for 5 to 7 hours while samples we
obtained.
Collection of close-in particulate samples was
being
Under the
technical direction of LASL, gas sample collection was supa@rvised by
Hq USAF, and gas separation and some analysis was performed by UCRL.
Shots:
All.
Radiation Exposure Potential:
Exposure potential existed fibr aircraft
crews, as well as for those processing samples upon the airpraft's return and those decontaminating the aircraft.
Staffing:
Five people were definitely associated with this]
project,
three from the 1009th (two civilians, one military), one cipilian from
LASL, and one civilian from UCRL.

Cloud Photography (Program 9)
A single project, Project 9.1, made up this program in ordef to determine the rise rate of the cloud and the height at which the clofs ceased
to rise.
