In radiation spectroscopy, there are mechanisms that displace the main spectrum characteristics (e.g. photo-peaks) and degrade their information. A very important mechanism of this type is pulse pile-up, due to which the measured pulse heights are shifted from their actual values. There exist various solutions to this problem, including pulse tail extrapolation and pulse shaping approaches. In the present study, a simplified “linear” extrapolation strategy is introduced and results are compared with those of the well-established “trapezoidal” pulse shaping method. Experimental assessment by using the data of a NaI(Tl) scintillation detector shows a good agreement between both strategies.
