Statistical evaluation of FRAM gamma-ray isotopic analysis data.
High-purity germanium (HPGe) detector gamma-ray spectra were analyzed using the FRAM (fixed energy, response function analysis with multiple efficiencies) gamma-ray isotopic analysis software. The analyses are based on multiple measurements of samples having well-documented isotopic composition from mass spectrometry measurements. Statistical analyses of the FRAM results are reported, the errors in FRAM analyses arising from the choice of detector type and the energy region are discussed, and the errors that resulted from sample-dependent and analysis-dependent effects are quantified.
