Analysis of gross alpha, gross beta activities and Be concentrations in surface air and statistical prediction model abstract
Measurement of grossα , grossβ activities and cosmogenic beryllium‐٧ ( 7Be ) concentrations were made both daily and weekly during ٢٠٠١, ٢٠٠٢, ٢٠٠٣ and ٢٠٠٤ from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (٣٥ ο ٤١' N) and Zahedan (٢٨ ο ٢٩' N). The data are sufficiently numerous to allow us to examine variations in time and through these measurements we have established atmosphere. The air concentrations of grossβ and grossα activities and 7Be concentration displayed a lognormal distribution during the study period. Both of β activities and 7Be have maximum concentrations during warm mid-year months. In this work, the data on concentration and meteorological data have been made use of in order to determine a model for gross α and grossβ and 7Be , respectively. The model can be used to estimate that part of the trend in grossβ and in 7Be levels that can be accounted for by trends in local meteorology. We didn’t find any relation between gross α and meteorology parameters. A satisfactory agreement between the results of the model and the measurements was highlighted.
