dc.description.abstractPhysical dating methods including thermoluminescence (TL), optically stimulated luminescence (OSL) and electron paramagnetic resonance (EPR) require the precise determination of the dose rate of experimental ionizing radiation. To determine the age of sediment by TL and OSL or EPR, it is necessary to accurately determine the exact mass fractions of 238U, 232Th, and 40K, since these concentrations are used in the calculation of the annual radiation dose. This work presents a comparative study of the determination of 238U, 232Th, and 40K using two analytical techniques: instrumental activation analysis (INAA) and γ-ray spectroscopy. The results presented in this paper are concordant between the two techniques.pt_BR
