DIRECTIONAL RESPONSL OF LOW-RANGE
GITR DETECTOR (INSIDE ©.15-INCH ALUMINUM
DRUM) TO BEAMS OF VARIOUS RADIATIONS
Values are comparisons to response of unshielded detector to
Cs5'37 pudiation beamed at top of detectori decree srmentation:.
Detector and drum were rutated in longitudinal plane about center of detector. Response is symmetrical about Jongitudinal
axis of detector.

DIRECTIONAL RESPONSE OF HIGH-RANGE
GITR DETECTOR (INSIDE 0.13-INCH ALUMINUM
DRUM) TO BEAMS OF VARIOUS RADIATIONS
Values are comparisons to response of unshielded detector to
Cs" radiation beamed at top of detector (0 degree orientation).
Detector and drum were rotated in longitudinal plane about center of detector. Response is symmetrical about longitudinal!
axis of detector.
