| Principles: |
| Radiochemical neutron activation analysis (RNAA) is used when greater sensitivities are
required than are provided by INAA. In this method, radiochemical separations on the irradiated material to isolate an
element or class of elements and gamma-ray spectrometry is performed on the separated fraction. Separations enhance
sensitivity by eliminating interferences and reducing background count-rates. For some applications, detection limits
can be improved by up to three orders of magnitude as compared with INAA. |
