Abstract

In this study, aerosol samples at Hanoi, Vietnam from February 2017 to January 2018 collected on the glass fiber filter were analyzed for 210Pb by using HPGe spectrometry. 210Pb weekly activity concentrations were in the range of 0.12 mBq.m-3 to 2.87 mBq.m-3 with an average value of 0.92 mBq.m-3 and 210Pb monthly activity concentrations were in the range of 0.99 mBq.m-3 to 9.24 mBq.m-3 with an average value of 4.01 mBq.m-3. The analysis of monthly averaged 210Pb activity concentrations revealed a dominant seasonal variability: high activity concentrations of 210Pb in winter and lower values in summer. The correlation between the activity concentrations of 210Pb in aerosol and the meteorological parameters (average temperature, precipitation and relative humidity) were observed and the obtained correlation coefficients are -0.95, -0.58 and -0.71, respectively.
