Abstract
In the analysis of environmental radioactive isotopes using gamma spectrometry, natural background radiation is an important parameter related to the analytical results directly. Therefore, in this work, the influence of natural background radiation was studied for two models: with and without shielding of gamma spectrometer system. The initial results showed that the minimum detectable activity (MDA) of radionuclides such as 234Th, 226Ra, 212Pb, 208Tl, 40K, 214Pb, 214Bi, 228Ac have the difference of two models from 10% to 503%. This is the basis for researches to improve the lead shielding chamber in the future.
