摘要: Air sample monitoring in Serbia, Belgrade started the 1960s, while (7)Be activity air and total (dry wet) deposition has been monitored for last 22 years by Environment Radiation Protection Department of Institute Nuclear Sciences, Vinca. Using this data collection, changes (wet dry) samples, as well their correlation with meteorological parameters (temperature, pressure, cloudiness, sunshine duration, precipitation humidity) that affect concentration atmosphere, were mathematically described using Fourier analysis. analysis confirmed expected; frequency largest intensity harmonic spectra corresponds to a period 1 year, same series parameters. To analyze quality results produced analysis, we compared measured values calculated according series. Absolute deviations between predicted mean monthly are range from 0.02 mBq/m(3) 0.7 mBq/m(3) air, 0.01 Bq/m(2) 0.6 Bq/m(2) samples. Relatively good agreement offers possibility prediction activity.
