that was used to obtain radiation data
at Operations Castle, Wigwam, and Redwing. The GITR’s
responses to gamma radiation were estimated for several
idealized source geometries and a variety of calculated
gamma energy spectra as a function of time. The
estimated response values are presented as fractions of
each detector’s calibration response to Co{sup 60}
radiation beamed at the side of that detector when
separated from its four-detector installation. The
estimated values of GITR response to radiological
environments likely to be encountered in the field did
not appear to depend significantly upon time after
fission nor upon exact knowledge about energy spectra or
source geometries. However, it was estimated that the
technique used to calibrate the GITR’s resulted in
slightly biased data; i.e., the calibrated doses or dose
rates were estimated to be between 10 and 20% too low. 8
