作为EURITRACK项目原则的标记中子检查系统的基本要求之一是一个高效和廉价的伽马射线探测器。为此，研究了圆柱形3“× 3”和5“× 5”BGO，以及3“× 3”、两种不同的5“× 5”和一种矩形5“× 5“× 10”NaI（Tl）晶体的特性。在这篇通讯中，我们报告的光产额，能量和时间分辨率的研究晶体在高能量的伽马射线。此外，晶体的效率的蒙特卡罗模拟的结果进行了比较，以峰总比实验获得的各种组合的光电倍增管和双折射
One of the essential requirements of the tagged neutron inspection system, which is the principle of the EURITRACK project, is an efficient and inexpensive gamma ray detector. For this purpose properties of cylindrical 3"times3" and 5"times5" BGO, and 3"times3", two different 5"times5", and a rectangular 5"times5"times10" NaI(Tl) scintillators were explored. In this communication we report on light yield, energy and time resolution of the investigated crystals at high energies of gamma-rays. Additionally, results of Monte Carlo simulations of the crystals' efficiencies are compared to peak-to-total ratios obtained experimentally for various combinations of PMTs and the scintillators
