| description | ANGLE software for semiconductor detector efficiency calculations - long
existing and widely accepted tool in quantitative gamma spectrometry - has
been recently extended to scintillation NaI detectors. The extension features
in the latest edition (ANGLE 4) and it is briefly outlined. Discretization of
reference efficiency curve, meaning possibility of using ANGLE 4 for
particular gamma energies without constructing the complete reference
efficiency curve, is particularly emphasized. This yields both in enhanced
practicality and higher accuracy, while reducing the potential for systematic
errors. The present work is primarily focussed on experimental verification
of ANGLE 4 for NaI detectors. Two detectors (2 ´ 2 and 3 x 3 inches) were
employed in the experiment. Commercially calibrated gamma sources (in the
forms of quasi point and cylinder) and homemade solutions (diluted from
calibrated ones) were measured at various distances from the detector(s),
ranging 0 cm to 50 cm. Energy range observed was 59 keV to 1408 keV.
Versatility of counting conditions, in terms of detectors and sources used,
gamma energies observed, source detector separations, etc., was aimed at
creating as large experimental evidence as possible for verification
purposes. Experimentally obtained efficiencies are compared with those
calculated by ANGLE 4. Very good agreement is obtained - well within the
experimental uncertainties - thus proving the reliability of the software. |
