Abstract: Based on ⁷Be inventories in undisturbed soil and daily rainfall data, ⁷Be deposition flux was estimated in Yangling District, Shaanxi Province, China. The results show that there is no significant difference between the measured ⁷Be mean concentration and the estimated in rainfall, which demonstrates that it is reasonable to use ⁷Be inventories in undisturbed soil to estimate ⁷Be mean concentration in rainfall and then calculate ⁷Be deposition flux. Inter and intra-annual variation of ⁷Be deposition flux is significant difference at the study site. The coefficient of variation for monthly ⁷Be deposition flux is 0.97. There is a marked seasonality in the seasonal values of ⁷Be deposition flux. Maximum value occurs in summer and minimum value occurs in winter. The annual ⁷Be deposition flux is 2069 Bq/m². The variation of ⁷Be inventory in undisturbed soil and ⁷Be deposition flux were determined by the precipitation amount and its temporal distribution. The strong linear correlation between ⁷Be deposition flux and precipitation amount is evident at different time scales.
