Project 2.51, - Neutron Flux eee and Shielding Studies - C.W. Luke
OBJECTIVES
To measure the neutron flux and energy spectrum as a function of
distance from the point of detonation of a Megaton device.
To compare the foil detector method of determing dose in rep
with chemical and semi-conductor dosimeter methods,
INSTRUMENTATION
The location of Project 2.51 stations vorgggmaliidceleliom,
(CHEROKEE) are shown in Fig. 2.51-1, page 29, Program
Program Book,
2 Consolidated
The stations consisted of concrete slabs on which were
bolted 141 x 54' x 1" steel plates,
The concrete slabs at the land
stations were 12' x 6' x 3' while the reef station was 21' x 6' x 6!,

.
The steel plates were oriented so that they would be perpendicular to
a line from the station to the proposed point of burst.
In order to
facilitate recovery, the neutron foil detectors were mounted on the
steel plates by means of specially designed "quick disconnect clamps".
The chemical and semiconductor dosimeters were placed in three inch
diameter pipe nipples and were clamped to a 3/8" cable stretched
between two eyebolts mounted on the concrete slab.
The following
detectors were placed at each station:
