title: Analysis of size-fractionated soil samples by gamma spectrometry.
abstract: The purpose of this work was to investigate the effect of particle size on radionuclides in soil, particularly in relation to depth. A set of soil samples at the 0-10cm and 10-20cm depth layers were collected, separated into size fractions using a sieving machine and analyzed by gamma spectrometry to determine (238)U, (226)Ra, (210)Pb, and (137)Cs. Significant variations between different size fractions and depth layers were observed. A 0-20cm depth profile was also investigated.
