Özet

The natural radionuclide Pb-210 was analysed in rainwater samples in Izmir by radiometric methods. The samples were collected continuously from January 2000 through December 2003 depending on the frequency of rain. The levels of Pb-210 in the samples were found to vary between 9 +/- 1 and 198 +/- 6 mBq l(-1) with an average value of 51 +/- 0.5 mBq l(-1). Po-210 activity concentration in total (wet and dry) deposition has also been investigated in the study from November 2001 to April 2003 and the results were found to vary between 2 +/- 0.4 and 35 +/- 3 mBq l(-1). The average value of Po-210 activity concentration is found as 8 +/- 0.5 mBq l(-1). Po-210/Pb-210 activity ratios were derived as between 0.03 and 1.09. The annual Po-210 and Pb-210 fluxes were 12 and 48 Bq m(-2) y(-1), respectively. (C) 2010 Elsevier Ltd. All rights reserved.
