Placed in the lead box and the truck driven to the 450 yi. station vhere
the rediation field was only 1 r/hr, and the camsras from this station
vere then recovered.
The following day, development of the plates from two of the
oameras at the XM yd, station and from one of the cameras at the 450
ya, station vere
ant
Bach of chefstacrrcor) cameras containe’ four plates vith
C2 emilsions, all at rear positions,
Two plates with Fl emisions
were placed at forvard raised positions,
.
The C2 emlaions from the 300 wil. station look to be readable,
They cannot be analysed on the Bicroseope thet we heve here (Parry
Telani).
There is no water cell to cool the illuainating bean, The
heat fron the intense light beam required pits the emilsion.
Pour hundred ant eighteen tracks vere measured on one of the C2
Plates fram the 450 yi. station by Clem Prye.
The results of this
analysis are shows in Table 12,2-) and the neutron energy spectrum
extrapolated back to the outeide of the bomb is show in Pig. 12.2-1.
Tt should be caphasised thet these date are preliniaary.
at-
tention is ealled to the mumber of tracks recoried for each half nev
energy interval ae shown in the table,
We wish to thank J, M411, R. Nevann and R. Moses for their
@esistanse in making last minute changes.
Alec we vould lire to state
our appreciation of the ecoperation which ve have received from Buddy
