摘要

gamma-Ray dose-rate increases associated with winter thunderstorm activities have been observed in the coastal areas facing the Sea of Japan. To investigate the generation of energetic photons that originate in thunderstorm electric fields, we have calculated the behaviour of electrons and photons hi electric fields with Monte Carlo method. In case of the calculation for the energetic electron emitted in the atmosphere, the electron and photon fluxes have increased greatly in the region with a strong electric field. Then, we have carried out the Monte Carlo transport calculations of the beta~- and gamma-rays emitted by radon progeny products, as a source of energetic electrons, in thunderstorm electric fields. From the calculated results, it is confirmed that the electron flux shows notable increases in the strong electric field, while the photon flux does not fluctuate significantly. Since the radon progeny products form a large part of the energetic electrons in the atmosphere, they can serve as the source of a considerable amount of electrons. This is indicative of the role of these electrons in the initiation of a lightning discharge.
