Аннотация. В статье проводится обзор математических моделей, которые описывают диффузионно-конвективный перенос радона в пористых геологических средах в рамках теории эманационного метода. Основу таких математических моделей составляет линейное нестационарное уравнение диффузии-конвекции радона для описания его переноса в однородном пористом грунте или системе «грунт-атмосфера» в зависимости от различных начальных и краевых условий. Основным инструментом исследования математических моделей является интегральное преобразование Лапласа, которое позволяет найти аналитическое решение поставленной задачи. Расчетные кривые, полученные согласно найденному аналитическому решению, позволяют установить закономерность процесса переноса радона и моделировать его в зависимости от различных физико- геологических параметров. Полученные решения можно использовать в прикладных задачах. В частности, в статье описывается алгоритм оценки плотности потока радона с поверхности Земли, обладающий повышенной чувствительностью к деформационным возмущениям в геологической среде. Далее обсуждаются обобщения ранее разработанных математических моделей, которые основаны на представлении о фрактальной структуре геосреды и математическом аппарате дробного дифференцирования. В стационарном случае построены модели супердиффузии (1 < \alpha < 2) и субадвекции (0 < \alpha < 1), показана их способность описывать аномально быструю миграцию радона к земной поверхности. Рассмотрена модель с переменным порядком дробной производной, позволяющая сопоставлять динамику объёмной активности радона с сейсмической активностью на примере Южной Камчатки. Полученные результаты могут быть использованы при мониторинге геодинамических процессов, поиске полезных ископаемых или в решении задач экологии. Необходимо отметить, что представленные в статье результаты были получены совместно с д.ф.-м.н. Фирстовым П.П. (06.04.1941-20.07.2021), который организовал сеть пунктов наблюдений по мониторингу радона на Камчатке. В 2026 году Фирстову П.П. исполнилось бы 85 лет. Данная статья посвящена этой знаменательной дате, а также является данью памяти и уважения коллеге и выдающемуся ученому, которым для автора был Фирстов П.П.
Ключевые слова: радон, диффузия, конвекция, супердиффузия, сейсмическая активность
