摘要

本研究报告了利用探地雷达(GPR)和伽马射线探测器对埋置铯-137放射源进行非侵入式深度估计。具体地说，利用探地雷达的体密度估计来拟合探测器数据的伽马射线衰减模型。当在沙子、砾石和土壤中埋入18厘米时，成功地估计了源的深度。这将有助于对核污染场地进行非侵入性监测。

Estimating the Depth of Buried Radioactive Sources using Ground Penetrating Radar and a Gamma Ray Detector

This study reports on nonintrusive depth estimation of a buried caesium-137 radioactive source using a ground penetrating radar (GPR) and a gamma ray detector. Specifically, the bulk density estimates from the GPR was used to fit a gamma ray attenuation model to the data from the detector. The depth of the source was successfully estimated when buried up to 18 cm in sand, gravel and soil. This will help in nonintrusive monitoring of nuclear contaminated sites.
