“…Furthermore, it can be affected by several mechanisms depending on parameters such as the agent of water, ground inclination, wind intensity and even vegetation [2]. In previous research [3] it has been observed that variations in the activity concentration of radionuclides exist not only between different sampling points and sampling depths at the same location, but also between different particle size fractions within the same sample. In particular, many radionuclides were detected in higher concentrations in the smaller particle size fractions of soil, rather than the larger ones.…”

Surface soil radioactivity is being studied at NED-NTUA since almost thirty years. The last few years this research has expanded to the study of soil particle size fractionation of radionuclides. The purpose of the present work was to study the tendency of many radionuclides to accumulate in the smaller particle size fractions. To this end, soil samples were collected from an area in the NTUA Campus where 241Am contamination, due to a failed 241Am-tipped lightning rod, had been previously detected. The samples were separated into size fractions using a sieving machine and analyzed by gamma spectrometry to determine 210Pb, 241Am, 234Th, 228Ra, 228Th, 226Ra, 7Be, 137Cs and 40K. The activity concentrations of these nuclides were found to significantly differ among the size fractions examined.
