The application of the technique of in situ gamma-ray spectrometry to the measurement of uranium isotopes in surface soils is described. A basic review of the in situ methodology using high resolution germanium gamma-ray spectrometers is given and specifics on calculated fluences, dose rates in air, and calibration factors are provided for relevant uranium isotopes and their progeny. The influence of the uranium depth distribution on measured concentrations is examined as it pertains to the comparison of in situ results with those obtained with soil sampling. Results from the analysis of spectra collected in the vicinity of the Fernald Environmental Management Project are presented as an example of the application of the technique.
描述了原位伽马射线能谱技术在测量表层土壤中铀同位素的应用。对使用高分辨率锗伽马射线能谱仪的原位方法进行了基本综述，并给出了相关铀同位素及其子体的计算注量、空气中剂量率和校准因子的具体信息。研究了铀深度分布对测量浓度的影响，这与原位测量结果与土壤采样结果的比较有关。作为该技术应用的一个例子，给出了在费纳德环境管理项目附近收集的光谱分析结果。
