Quantification of radionuclide activities in gamma spectrometry can be a challenging task. It depends on efficiency calibration, peak area calculation, nuclide decay data and correction factors, such as attenuation or true coincidence summing corrections. These quantities present significant challenges to an accurate analysis. is therefore desirable have way assessing the quality quantification...

abstract background: the radiological impact of the use of phosphate fertilizers in soil is due to the internal irradiation of the lung by the alpha particles, short lived radon-thoron progeny and the external irradiation of the body by gamma rays emitted from radionuclides in situ. this paper describes the results of gamma spectrometric measurements of the concentration of the natural radionuc...
