Determination of uranium and thorium in geological samples by mass spectrometry and neutron activation analysis
- 1. Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, SP (Brazil)
Description
The isotope dilution mass spectrometry technique and neutron activation analysis were employed for the determination of U and Th concentration is stream sediment and soil provided by the International Atomic Energy Agency (IAEA) and in granitic rock samples from Wyoming area (U.S.A.). The concentration results for U and Th, determined with precision better than 5% show a good agreement with the date from literature, presenting relative error in the order of 1% to 14% for U and of 1% to 11% for Th.
