Abstract

A comparison of the calculated absolute full-energy peak efficiencies of CdTe and NaI detectors, i.e. the ratio of the number of counts under the full-energy peak (FEP) to the number of photons at the same energy emitted by the source, is made for six different detectors and three source sizes. The CdTe and NaI detectors are assumed to be of equal volume. The calculations are performed in the photon energy region 15-2000 keV using water, muscle and blood as source media.

CdTe和NaI探测器在15-2000 keV光子区域的计算绝对全能峰值效率的比较
比较了CdTe和NaI探测器计算的绝对全能峰值效率,即在全能峰值(FEP)下的计数数与源发射的相同能量的光子数的比率,对六种不同的探测器和三种源尺寸进行了比较。假设CdTe和NaI探测器的体积相等。计算在15-2000 keV的光子能量区域进行,使用水、肌肉和血液作为源介质。
