Project 2.64 - Fallout Location and Delineation by Aerial Survey R. Graveson
OBJ FCTIVES
To survey the gamma radiation from fallout contaminated ocean
areas using an aircraft borne detector.
To make air absorption
measurements to correlate the aircraft date with the intensities
measured at the surface of the sea.
INSTEIM™NTATION
Three P2ev—5 aircraft were equipped with gamma radiation detectors to record the dose rate arriving through the thin aircraft
skin from a water surface below,
RESULTS
Flights were accomplished on D, D4 1, D # 2 and D f 3 days
with one aircraft.
The area north of Bikini Atoll from 315° to 45° T to a distence
of about 175 miles was covered by the surveys.
The contaminated area
extenied north of Bikini approximately 125 miles between the bearings
340° and 30° T.
The aircraft Program 2 Control Center telemeter system did not
Operates
The radiation detector system operated and on D #4 1 through D ¢ 3
the intensity measured at the aircraft was relayed to the Program 2
Plot Center via voice radio,
With this data it was possible to con-
struct a plot showing roughly the characteristics of the contaminated
area,
