Concentrations of Be-7 in surface air samples were continuously measured, using a low-background HPGe spectrometer at Belgrade (Kumodraž), Serbia. Weekly data collected over a 12 month period, from July 2008 to June 2009, are presented and discussed. The measured values of Be-7 activity concentrations in surface air samples, ranged from 1.9 mBq/m3 to 10.2 mBq/m3, show increase in summer season.
Key words: radioactivity, radionuclides, air, concentration, gamma spectroscopy.
