Abstract

This article focuses on the seasonal and regional behavior of atmospheric concentrations of the natural radionuclides beryllium-7 (^7Be) and lead-210 (^210Pb) in Hirosaki City, Japan. Weekly aerosol samples collected from 2019 to 2023 showed that ^7Be and ^210Pb concentrations exhibit similar seasonal trends, increasing in autumn and winter and decreasing in spring and summer, with precipitation playing a significant role in their atmospheric removal. The study found a strong positive correlation between ^7Be and ^210Pb levels, despite their different production sources, suggesting consistent removal mechanisms influenced by factors such as snowfall and rainfall characteristics. These findings contribute to understanding atmospheric processes in a region characterized by heavy snowfall, though further data are needed to clarify the relationship between radionuclide concentrations and meteorological variables.
