These included the film badges for measuring gamma radiation
as a function of distance, and the heat sensitivity papers,
These
stakes had to be driven along two radii on Engebi and on the adjacent

upwind islands.
Shields consisting of steel plates and concrete blocks
were fixed in position.
At several stations racks were installed for
the exposure of panels to measure heat sensitivity.
In addition, special
panels were prepared containing as many as 50 different materials com

order to measure the spectral and time distribution of the optical radiation .
Two test animal containers were positioned on land and two were
anchored at the proper distances off shore,
The heavy steel cylinders
for the exposures of biological mtcrials at close range were located at
several distances,
Much of the work involved in these preparations was primarily mnual
labor and could have been carried out quite satisfactorily with a working

One phase of the pre-test operations of TU 7.6.6 consisted of deter-
mining the sensitivity of the Test materials through normal exposure of
heat, humidity, and wind.
The biological exposure cans were located in
position and painted or covered with a variety of materials.
