摘　　要：利用由NaI(加微量Tl)和CsI(加微量Na)共同组成闪烁计数器探测器对雷暴条件下的高能辐射进行了初步观测。结果表明,雷暴条件下的辐射比晴天条件下的辐射复杂的多,其能量高出约6 000～10 000keV。当雷暴过程中闪电引起的近地面电场变化较强时,探测器所测得的能量相对较高;而当雷暴过程中闪电引起的近地面电场变化较弱时,高能辐射能量则相对减弱,这从一定程度上说明雷暴条件下高能辐射能量的变化增强。The photomultiplier detector system is consisted by NaI（T1） and CsI（Na）.The energetic radiation under the thunderstorm condition was preliminary observed using the detector system.Through the analyzing,the energy of energetic radiation under the thunderstorm condition was more complex than that of fine condition.The energy under thunderstorm condition was higher about 6 000 keV to 10 000 keV than that of fine condition.When the electric field caused by the thunderstorm was stronger,the energy was detected by the detector quite higher.But the energy was decreased when the field caused by the thunderstorm was weaker.It showed that the energy of energetic radiation was increased under the thunderstorm condition.
