In the framework of environmental measurements by gamma-ray spectrometry, some laboratories need to characterize samples in geometries for which a calibration is not directly available. A possibility is to use an efficiency transfer code, e.g., ETNA. However, validation for large volume sources, such as Marinelli geometries, is needed. With this aim in mind, ETNA is compared, initially to a Monte Carlo simulation (PENELOPE) and subsequently to experimental data obtained with a high-purity germanium detector (HPGe).
在通过伽马射线能谱法进行环境测量的框架内,一些实验室需要对校准数据无法直接获取的几何形状的样品进行表征。一种可能的方法是使用效率转换代码,例如ETNA。然而,需要对大体积源(如马林内利几何形状)进行验证。出于这一目的,首先将ETNA与蒙特卡罗模拟(PENELOPE)进行比较,随后再与用高纯锗探测器(HPGe)获得的实验数据进行比较。
