Abstract In this study, the high-frequency and long-term continuous monitoring data of the γ radiation air absorbed dose rate nearby the three nuclear power plants in Guangxi(Fangchenggang City) and Fujian(Fuqing City and Ningde City) Province was comprehensively discussed from the perspective of different time scales to explore the variable characteristics and regulation mechanism of the γ radiation air absorbed dose rate. At the interannual scale, the γ radiation air absorbed dose rate had a reverse relationship with solar activity on the basis of long term monitoring at Yushandao station in Ningde City from 2014 to 2020. At the seasonal scale, the East Asian monsoon dominantly contributed to the seasonal characteristics of low in summer and high in winter for the γ radiation air absorbed dose rate. At the diurnal scale, tide significantly affected the diurnal fluctuations of the γ radiation air absorbed dose rate. At the hour scale, rainfall event would remove the radon progenies of ²¹⁴Pb and ²¹⁴Bi from the atmosphere to the surface soil, leading to a sudden increase in the γ radiation air absorbed dose rate.

Key words： nuclear power plant γ radiation air absorbed dose rate East Asia monsoon rainfall event solar activity tide
