The effect of other activities on INAA limits of detection

The instrumental neutron activation analysis (INAA) Advance Prediction Computer Program (APCP) is described, as well as its areas of usefulness. Particular attention is devoted to its ability to predict g and ppm INAA lower limits of detection (LOD's) of any particular elements of interest in any sample matrix type of even very approximately known average or typical elemental composition. In general, INAA g LOD's are found to be 10 to 100 times higher than the corresponding interference-free values, and INAA ppm LOD's are found to be 100 to even 100 000 times higher than the corresponding interference-free values calculated for a one-gram sample.
