摘要

进行实验以确定电离辐射水平的变化是否引起放电起始电压的可探测变化。在四种情况下测量了尖阴极直流电晕放电的起始电压：1)环境条件；2)屏蔽条件；3)存在β源时；4)在伽马源存在的情况下。结果表明，当伽马或β辐射源放置在放电区附近时，起始电压降低了几百伏。在不同情况下，没有检测到消光电压的差异。此外，在电离辐射的存在下，观察到起始电压的可变性显著降低。

Effects of Ionizing Radiation on the Inception Voltage of Electrical Discharges

Experiments are carried out to determine if the changes in the level of ionizing radiation provoke detectable changes in the inception voltage of electrical discharges. The inception voltage for dc corona discharge from a sharp cathode is measured for four cases: 1) ambient conditions; 2) shielded conditions; 3) in the presence of a beta source; and 4) in the presence of a gamma source. The results indicate a decrease of a few hundred volts in the inception voltage when the sources of gamma or beta radiation are placed in the proximity of the discharge zone. No difference in the extinction voltage is detected between the different cases. Additionally, variability in the inception voltage is observed to be notably reduced in the presence of ionizing radiation.
