Flying Hours

Initial Gamma Radiation Survey
Gamma radiation survey of three islands,

Eniwetok (Fred), Parry (Elmer), and Japtan (David).
This survey will consist of a cross-hatched grid of
flight lines spaced 150 feet apart.

Sets of parallel

flight lines will be flown perpendicular to each other.
Two surveys will be flown for each island to record

gamma energies consistent with cobalt {0 to 3.0 MeV)
and americium (0 to 300 keV).
3,

(6 hrs, 2 flights)

Multispectral Photography
Four camera multispectral photographic survey

of all islands in the entire atoll to include the follow-

ing four wavelength bands:
a.

Normal color (Kodak Aerocolor negative

film)

b.

Infrared color (Kodak Aerochrome positive

film)

Black and white, red filter (Kodak Plus-X)
d.

IR black and white (Kodak Infrared)

This survey will be flown as lighting and

cloud cover permit.
4,

Complete Gamma Radiation Survey
Gamma radiation survey of remaining islands.

Each island will be surveyed with a cross-hatched grid.
Two grids will be flown for each island,

1) for cobalt

and cesium (0 to 3.0 MeV), and 2) for americium

(8 hrs, 4 flights)
