Abstract: | A new approach is presented for neutron activation analysis using the monostandard (single comparator) method. Elements to
be determined are classified into two groups; those with σo>Io are activated with whole neutron spectrum (without Cd-cover), using a standard of the same group (e.g. Sc), while elements
with Io>σo are activated with epithermal neutrons (under Cd-cover) using a standard of the same group (e.g. Au or Co). Epithermal activation
increases the number of determinable elements and its coupling with the monostandard method has the advantage of using a small
Cd-cover. The σo and I0 values of some elements were determined to test this approach. |
