In situ gamma-ray measurements were taken at eight locations in the Gran Sasso National Laboratory (Italy). Count rates for gamma radiation within the energy range of 7-2,734 keV varied from 8 to 60 γ s. The arithmetic mean was 49 γ s for measurements taken without a collimator. The average gamma flux inside the Lab was 0.25 γ cm s. The sedimentary rocks surrounding the Lab are characterized by low activity concentrations of uranium and thorium, equal to 1.7 and 1.4 Bq kg, respectively.
在意大利大萨索国家实验室的八个地点进行了原位伽马射线测量。7 - 2734 keV能量范围内的伽马辐射计数率在8至60γ/s之间变化。无准直器测量时的算术平均值为49γ/s。实验室内部的平均伽马通量为0.25γ/cm²s。实验室周围的沉积岩具有低铀和钍活度浓度的特征，分别为1.7和1.4 Bq/kg。
