Abstract

The activity concentrations of K, Th, and U in the characteristic rocks of the Modane-Aussois region (Western Alps, France) were determined using an HPGe gamma-ray spectrometry system. The activity concentrations of K varied from 18 Bqkg (limestone dolomite) to 392 Bqkg (calcschist), while those of Th varied from 0.7 Bqkg (limestone dolomite) to 18 Bqkg (calcschist). The activities associated with U ranged from 9 (quartzite) to 29 Bqkg (dolomite). In the investigated rock samples, concentrations of U (ppm) and K (%) had a strong negative correlation.

摘要

利用高纯锗γ射线能谱系统测定了法国西阿尔卑斯山莫达讷 - 奥索瓦地区特征岩石中钾（K）、钍（Th）和铀（U）的活度浓度。钾的活度浓度范围为18贝克勒尔每千克（石灰岩白云岩）至392贝克勒尔每千克（钙质片岩），钍的活度浓度范围为0.7贝克勒尔每千克（石灰岩白云岩）至18贝克勒尔每千克（钙质片岩）。与铀相关的活度范围为9（石英岩）至29贝克勒尔每千克（白云岩）。在所研究的岩石样品中，铀的浓度（ppm）与钾的浓度（%）呈强负相关。
