NaI(Tl) Detector Efficiency Computation Using Radioactive Parallelepiped Sources Based on Efficiency Transfer Principle
The efficiency transfer (ET) principle is considered as a simple numerical simulation method, which can be used to calculate the full-energy peak efficiency (FEPE) of 3″×3″ NaI(Tl) scintillation detector over a wide energy range. In this work, the calculations of FEPE are based on computing the effe...
