Determination of 29 Elements in 8 Argonne Premium Coal Samples by Instrumental Neutron Activation Analysis

Table 4. Average percent corrections made for spectral interferences on counts with the lowest errors during INAA (instrumental neutron activation analysis) of eight Argonne Premium Coal samples.
[-- indicates no correction was made; <0.1 indicates an extremely small correction was made. No corrections were required for spectral interference of the 160Tb line by the 233Pa line in any of these samples. Data for individual splits have been reported by Palmer (1991)]
