Abstract

The paper considers an algorithm for correcting the instrumental spectrum of the gamma-radiometer with a NaI(Tl) detector. The algorithm is based on the ME-LM method (Maximum Likelihood Estimation using Expectation Maximization), which uses a detector response matrix obtained by Monte Carlo simulation. The main advantage of the algorithm is the rescaling procedure, which significantly reduces the spectrum processing time.
