| Abstract: | The optimum collimator design in terms of
aperture and thickness for accomplishing improved performance for wide energy
radiation field has been investigated in the present paper. A 2" 2" NaI(Tl) detector was used as sensor in proposed Hot Spot Identification
system. The spectral response of the detector with various collimator apertures
and thickness was developed using Monte Carlo methods for optimizing the
collimator design. The optimum size of collimator aperture is found to be 2 mm
and thickness of 5 cm. Studies were also carried out to optimize lead shield
thickness around the detector.
