Abstract

pine needles. Activity concentrations of the concerned radionuclides in the needle samples were as follows: Be-7, 24.6 +/- 2.40 to 210 +/- 7.21 Bq kg(-1), K-40, 23.5 +/- 12.4 to 287 +/- 15.6 Bq kg(-1), Ra-226, 0.44 +/- 0.12 to 12.3 +/- 2.18 Bq kg(-1), and (CS)-C-137, 0.61 +/- 0.30 to 2.29 +/- 0.38 Bq kg(-1). It is found that the frequency distributions obtained for Be-7 and (CS)-C-137 can be fitted to a normal distribution, and for K-40 and Ra-226 can be fitted to a log-normal distribution.
