Spectral characteristics of x-ray and gamma radiation in long-term growth events

The work is devoted to the study of a little-studied phenomenon: an increase in X-ray and gamma radiation coming from the atmosphere during precipitation. In this work, attention is focused on the analysis of long-term increase events, which occur rarely and differ from typical increase events in slow growth and the presence of many maxima. A differential spectrum meter for electromagnetic radiation in the range of 0.1–4 MeV is used. An analysis of the spectra measured in long-term increase events showed that the characteristics of the spectra do not differ from the same characteristics in ordinary increases. It is concluded that long-term events do not differ from ordinary ones and are due to the same reasons.
