摘要：

The effect of the composition of the used standard reference material (SRM) on results of determination of fallout radionuclides in soil samples was studied. Using five soil types as SRMs, we measured the specific activity of Pb-210 and Cs-137 in six target samples of Chestnut soil. It was observed that the determination of the Pb-210 activity in the samples depended on the chemical composition of SRMs used to create the efficiency curves. Thus, using SRMs similar in chemical composition to the target samples should improve accuracy in the determination of Pb-210 in environmental samples. (C) 2010 Elsevier Ltd. All rights reserved.
