本文介绍了X射线和γ射线的相对衰减在测量混凝土中放射性污染深度中的应用，并以~（137）Cs的光子能谱为基础。这已经在两个定制的幻影与压制/铸造混凝土和硅砂突出亚毫米深度分辨率的潜力进行了测试。这项研究强调了在现场应用之前易于校准的重要性，并提高了对传统设施中材料成分的了解。(C)2009爱思唯尔有限公司版权所有。
An application of the relative attenuation of X rays and gamma rays for the measurement of depth of radioactive contamination in concrete and is described, based upon the photon energy spectrum of caesium-137. This has been tested on two bespoke phantoms with pressed/cast concrete and silica sand highlighting the potential for sub-millimetre depth resolution. This research highlights the importance of the ease of calibration, prior to application in the field, and improved knowledge of materials composition in legacy facilities. (C) 2009 Elsevier Ltd.
