   <abstract xml:lang="ru">
    <p>Представлены результаты измерений дифференциальных спектров электромагнитного излучения в диапазоне 0.1–4 МэВ, возникающего в атмосфере как компонента вторичных космических лучей. Мониторинг спектров выполнялся в 2022–2023 гг. с помощью спектрометра на основе кристалла NaI(Tl). Основной целью измерений являлось определение спектральных характеристики электромагнитного излучения во время событий возрастания, когда поток электромагнитного излучения из атмосферы увеличивается на десятки процентов по отношению к среднему уровню. На основе тщательного анализа спектров многих десятков событий делается вывод: хотя линии естественных радионуклидов присутствуют в спектрах и вносят свою долю, их суммарный вклад в события возрастания составляет ~0.1 от полной энергии, привнесенной при возрастании. Делается однозначный вывод, что эффект возрастания электромагнитного излучения при осадках не обусловлен наличием радионуклидов в осадках.</p>

    <p>We report the measurement results of differential spectra of electromagnetic radiation in the range 0.1–4 MeV, which occurs in the atmosphere as a component of secondary cosmic rays. Spectral monitoring was performed using a spectrometer based on the Nai (TL) crystal in 2022–2023. The main purpose of the measurements was to determine spectral characteristics of the electromagnetic radiation during increase events, when the electromagnetic radiation flux from the atmosphere rises by tens of percent with respect to the background level. From a thorough analysis of the spectra of many dozens of events, we have drawn a conclusion that although the lines of natural radionuclides are present on the spectra and contribute their share, their total contribution to the increase events is ~0.1 of the total energy supplied during an increase. We unambiguously conclude that the effect of increasing electromagnetic radiation during precipitation is not due to the presence of radionuclides in precipitation.</p>
