Concentrations of Pb-210, Be-7 and Cs-137 in moss samples were continuously measured, using low-background HPGe spectrometer at Novi Sad, Serbia (45 degrees 14'45 '' N, 19 degrees 51'35 '' E). Weekly data collected over 14 month period from January 2007 to March 2008 are presented and discussed. Measured values of Be-7 activity concentrations in dry moss samples are ranged from 201 to 920 Bq/kg showing prominent increase in summer and autumn season. Data for Pb-210, ranged from 347 to 885 Bq/kg do not show such trend. The average concentration of Cs-137 is 8.9 Bq/kg. It is shown that yield of Be-7 can be estimated using average values of activity concentrations. Precipitation amount and duration of precipitation are measured and their possible influence on activity concentrations measured in moss samples was considered. (C) 2009 Elsevier Ltd.
