Теорией возраста нейтронов дается корректное описание полей быстрых нейтронов от плоского радиоактивного источника при энергии источника не превышающей 1 МэВ. Эффект атмосферной неоднородности влияет на высоту источника свыше 20–25 км. Плотность потока медленных нейтронов снижается почти до нуля на расстоянии около двух параметров атмосферной неоднородности.</p></abstract><trans-abstract xml:lang="en"><p>The question of the spatial distribution of fast and thermal neutrons in the Earth’s atmosphere is considered. The fields of fast neutrons from a flat radioactive source with a source energy not exceeding 1 MeV are correctly described by the age theory. The effect of atmospheric in homogeneity affects the height of the source, exceeding 20-25 km. The flux density of slow neutrons falls almost to zero at a distance of about two parameters of the atmospheric in homogeneity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поток нейтронов</kwd><kwd>атмосфера Земли</kwd><kwd>гетерогенность</kwd><kwd>квази-рассеивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neutron flux</kwd><kwd>Earth's atmosphere</kwd><kwd>heterogeneity</kwd><kwd>quasi-diffusion</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">V.I.
