Abstract

Relativistic runaway electron avalanches (RREAs) developing in electrified clouds produce gamma radiation which could be observed on the ground surface and on near-Earth orbit. Radio emission of RREAs is a much less studied manifestation of the avalanche process. Meanwhile, very high frequency (VHF) radiation can be used as an additional source of information on conditions of the RREA development. We present the method of calculating the VHF signal produced by RREAs using Monte-Carlo simulation with GEANT4 toolkit. We show that VHF radiation produced by runaway electrons has a maximum at frequency range 0.1-1 MHz, the amplitude is below the background noise.
