摘要
A method for correcting detected gamma ray spectra for the effects of energy analyzer pileup includes assigning detected gamma rays to channels in a multichannel analyzer (MCA). A pileup spectrum is estimated. The pileup spectrum is subtracted from the measured spectrum. The result thereof is compared to the preceding estimated pileup free spectrum and the estimating the pileup spectrum, subtracting the pileup spectrum and comparing is repeated until the difference between successive estimates of the pileup-free spectrum falls below a selected threshold.
