In situ gamma-ray measurements were taken at six locations in the Modane Underground Laboratory. Count rates for gamma radiation within the energy range of 7-2734 keV varied from 15 to 108 γs. The arithmetic mean was 79 γs for measurements taken without a collimator. The metamorphic rocks surrounding the Lab are characterized by low activity concentrations of uranium and thorium equal to 12 and 10 Bq kg, respectively.
在莫达讷地下实验室的六个地点进行了原位伽马射线测量。能量范围在7 - 2734千电子伏特内的伽马辐射计数率在15至108γ每秒之间变化。在不使用准直器的情况下进行测量，其算术平均值为79γ每秒。实验室周围的变质岩的特点是铀和钍的活度浓度较低，分别为12和10贝克勒尔每千克。
