Intercomparison NaI(TI) and HPGe spectrometry to studies of natural radioactivity on geological samples

摘要

In this study, in situ gamma spectra using NaI(TI) detector have been compared with the laboratory measurements by using HPGe detector on geological samples. The results for measuring naturally occurring terrestrial gamma radiation of K-40 and the decay series of Th-232 and, U-238 respectively of both detectors show a maximum deviation about 5%. The mass activities series from both detectors were checked for coherence using proficiency test procedure from the International Atomic Energy Agency. The reliability and precision pass for final scores for all the analytical determinations of are received "acceptable" for all radionuclides. (C) 2016 Elsevier Ltd. All rights reserved.
