N2 - Four calculation codes were implemented on
experimental data to calculate corrections of common
systematic effects within high resolution gamma spectrometry.
The detector parameters were sparsely optimized
to imitate the usage that can be expected from personnel
with limited experience. The transfer of the efficiency from
the calibration geometry (60 ml, density 1.0 g/cm3) to
200 ml geometry (density 1.5 g/cm3) failed with all codes,
which was discouraging. However, a majority of the other
corrected activities deviated with less than 10 % from the
reference activity values, even for density corrections or
when corrections had been calculated for new sourcedetector-
geometries. Smaller deviations, around 5 % or
less, were achieved when corrections were done within the
calibrated geometry. This shows a robustness of the calculation
codes even if the in-data is not fully optimized.
