Table 9.2 Measurement of Differential Spectrum
Nicholas Tsoulfanidis · 2010
Consider, for example, the measured pulse-height distribution shown in Figure 9.9b produced by a monoenergetic gamma source. This distribution (or spectrum) is obtained using a scintillation counter. The observer records the data shown in Figure 9.9b, which is not identical to that of the source, Figure 9.9a. The objective of the measurement is to obtain the spectrum of Figure 9.9a, but the observer actually measures the distribution shown in Figure 9.9b. The task of the observer is, therefore, to apply appropriate corrections to the measured spectrum to nally obtain the source spectrum.
