Abstract

Background: Measurement of gross a, gross b activities, and cosmogenic beryllium-7 (7Be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (35o41' N) and Zahedan (28o29' N). Materials and Methods: Weekly aerosol samples were collected with the high-volume air samplers on cellulose filters to determine the 7Be contents of samples, using a semiconductor gamma spectrometer. Airborne dust samples were collected on daily basis on fiber glass filters and used to determine the gross a and gross a activities with automatic beta analyzer and a ZnS (Ag) counter, respectively. In this study, the concentration and meteorological data were used to determine models for gross a, gross b and 7Be. Results: The air concentrations of gross b and gross a activities and 7BE CONCENTRATIONS displayed lognormal distributions during the study period. Both b and 7Be had maximum activity concentrations during warm mid-year months. Conclusion: The models can be used to estimate the part of the trend in gross b and in 7Be levels that can be accounted for by-trends in local meteorology. There has been a satisfactory agreement between the results of the model and the measurements.
