    • A method for automatic drift stabilization in radiation measurement with a detector, a pulse amplitude integral of measured radiation being produced as a standard for the radiation energy absorbed by the detector, using control devices connected to the output side of the detector to adjust the amplification of the detector output on the basis of a defined threshold in the detector output pulse energy spectrum in such a manner that the rate of all detector output pulses having a pulse height greater than the threshold is kept constant, and the measurement result is correspondingly corrected thereby, wherein the threshold is located in the vicinity of a peak in the pulse amplitude spectrum that is caused by the energy loss of naturally occurring cosmic radiation or a component thereof in the detector.
    • 一种用于利用检测器进行辐射测量的自动漂移稳定的方法,利用连接到检测器的输出侧的控制装置,产生测量的辐射的脉冲幅度积分作为由检测器吸收的辐射能的标准,以调整放大 所述检测器以检测器输出脉冲能量谱中的定义阈值为基础,以使得具有大于阈值的脉冲高度的所有检测器输出脉冲的速率保持恒定,并且相应地校正测量结果, 其中所述阈值位于由所述检测器中的天然存在的宇宙辐射的能量损失或其成分引起的脉冲幅度谱中的峰值附近。
