| dc.description.abstract | A simple method for the determination in sediment samples of low-energy gamma-emitters with coaxial Ge detectors
and using a cylindrical sample geometry is outlined. This method allows an easy estimation of self-absorption effects by
knowing the apparent densities and the composition of the investigated samples. As calibration matrixes solid samples
enriched in known amounts of natural radionuclides emitting low-energy gamma rays were used. In this way, the
difficult homogenisation steps needed when liquid spikes are added to a solid blank for manufacturing the calibration
sample are avoided.
The method has been carefully checked and validated by applying it to sediment samples with known activities of
some low-energy gamma-ray emitters. Additionally, these sediment measurements have allowed to evaluate the
magnitude and importance of the self-absorption corrections. | es |
