      <abstract xml:lang="ru"><p>Получены статистические характеристики изменений интенсивности годового и сезонного облучения на верхней границе атмосферы пятиградусных широтных зон Арктического региона в неоплейстоцене. Не выявлена связь интенсивности годового и сезонного облучения пятиградусных широтных зон с эксцентриситетом земной орбиты, однако выявлена положительная заметная связь интенсивности летнего облучения и отрицательная интенсивности зимнего облучения с изменением наклона оси и долготы перигелия. Максимальный размах колебаний зимней интенсивности облучения в Арктике с географической широтой в неоплейстоцене заметно (на 10,211 Вт/м2) уменьшается, в то время как максимальный размах колебаний летней интенсивности облучения с географической широтой слабо (на 4,3 Вт/м2) увеличивается. Коэффициент корреляции летней интенсивности облучения и долготы перигелия в неоплейстоцене с географической широтой уменьшается, а с наклоном оси вращения – увеличивается. Модуль коэффициента корреляции зимней интенсивности облучения с долготой перигелия уменьшается, а с углом наклона оси – увеличивается. Максимальный размах изменений интенсивности годового и сезонного облучения пятиградусных широтных зон в неоплейстоцене на 1–2 порядка превышает максимальные вариации показателя δ18О изотопно-кислородного анализа донных фораминифер, что показывает необоснованность использования его значений для решения задач геохронологии и климатостратиграфии неоплейстоцена.</p></abstract>      <trans-abstract xml:lang="en"><p>Statistical characteristics of changes in the intensity of annual and seasonal irradiation at the upper boundary of the atmosphere of 5-degree latitude zones of the Arctic region in the Late Pleistocene were obtained. No relationship was found between the intensity of annual and seasonal irradiation of 5-degree latitude zones and the eccentricity of the Earth&#039;s orbit, but a positive noticeable relationship was found between the intensity of summer irradiation and a negative relationship between the intensity of winter irradiation and a change in the tilt of the axis and the longitude of the perihelion. The maximum range of variations in winter irradiation intensity in the Arctic with geographic latitude in the Late Pleistocene noticeably (by 10,211 W/ m2) decreases, while the maximum range of variations in summer irradiation intensity with geographic latitude slightly (by 4.3 W/m2) increases. The correlation coefficient of summer irradiation intensity and perihelion longitude in the Late Pleistocene decreases with geographic latitude, and increases with the tilt of the rotation axis. The modulus of the correlation coefficient of winter irradiation intensity with perihelion longitude decreases, and increases with the tilt of the rotation axis. The maximum range of changes in the intensity of annual and seasonal irradiation of 5-degree latitudinal zones by 1–2 orders of magnitude in the Late Pleistocene exceeds the maximum variations in the δ18 O isotope-oxygen analysis of benthic foraminifera, which shows the groundlessness of using its values to solve problems of Late Pleistocene geochronology and climatostratigraphy.</p></trans-abstract>
