Abstract Terrestrial gamma and neutron flashes can result in considerable radiation exposure of aircraft crew and passengers in their close vicinity. Lightning impulse voltage generators imitate selected stages of natural lightning processes and can serve as a test environment for the development and calibration of detector systems for such short term radiation events. This work presents the results of measurements of absorbed dose using thermoluminescent dosimeters for 400 negative discharges at the lightning impulse voltage generator. The thermoluminescent dosimeter CaSO4:Dy and the combination of lithium-fluoride detectors MTS–6, MTS–7, and MTS–N were used to quantify the photon and neutron components of the radiation field. The detectors were placed in four positions near the generator spark gap. The results confirm the presence of thermal neutrons and photon radiation in two positions at the lightning impulse voltage generator.

在实验室条件下由火花放电引起的辐射的测量

摘要 地面伽马和中子闪光会导致附近的飞机机组人员和乘客受到大量辐射。雷电脉冲电压发生器模仿自然闪电过程的选定阶段，可作为针对此类短期辐射事件开发和校准探测器系统的测试环境。这项工作介绍了使用热释光剂量计对雷电脉冲电压发生器进行 400 次负放电测量吸收剂量的结果。热释光剂量计 CaSO4:Dy 和氟化锂探测器 MTS-6、MTS-7 和 MTS-N 的组合用于量化辐射场的光子和中子分量。探测器被放置在靠近发电机火花隙的四个位置。
