Criteria for data elaboration of gamma spectra of ambient samples
Abstract
An analysis of low frequency count gamma spectra data processing, from ambient samples measured with Ge(Li) detectors is presented. Some concepts are examined, such as peak significance and minimum detectable count for a given background. Solutions are suggested for the determination of the peak area, for the computation of the confidence interval and for transformation of counts in concentration (pCi/kg). A model is proposed for the evaluation of the efficiency curve as a function of the energy based on polynomial regression techniques.
