| Abstract: | An account is given of the role and the strength of k0-INAA to assess the annual radiation dose (contribution of U, Th, K and Rb) for use in TL/OSL dating of sediments. Mention is made of: (1) its simplicity of sample preparation, (2) its accuracy and even its reference character for other elemental determination methods, (3) the possibility of obtaining the Rb content with no extra effort and (4) its capability to easily and reliably quantify U and Th in a small amount of etched quartz grains, followed by evaluating the importance of their presence in the quartz inclusion technique. |
