High resolution gamma spectrometry offers a rapid method to characterise waste materials on a decommissioning nuclear site. To meet regulatory requirements, measurements must be traceable to national standards, meaning that the spectrometers must be calibrated for a wide range of materials. Semi-empirical modelling software (such as ANGLE™) offers a convenient method to carry out such calibrations.This paper describes an assessment of the modelling software for use by a small laboratory based on a nuclear site. The results confirmed the need for accurate information on the detection construction if the calibration were to be accurate to within 10%.
► The efficiency transfer software, ANGLE V.3, has been assessed. ► Computed efficiency calibration curves were compared to experimental results. ► A variety of geometries and matrices was investigated. ► A new approach is suggested for correcting results for inaccurate detector spec. ► The software was found fit-for-purpose for use in a nuclear decommissioning lab.
