Design for an asymmetrical cyclic neutron activation process for determining fluorite grade in fluorspar concentrate

Conventional neutron activation procedures rely on cycles of equal length to test samples of fluorspar concentrate. This paper proposes a new procedure using “asymmetrical” cycles, in which the duration of the first cycle is different from that of the subsequent activation cycles, which are conducte...

Summary:Conventional neutron activation procedures rely on cycles of equal length to test samples of fluorspar concentrate. This paper proposes a new procedure using “asymmetrical” cycles, in which the duration of the first cycle is different from that of the subsequent activation cycles, which are conducted once the radioactive concentration of the element of interest has been partly reduced through radioactive decay. A comparison is made between the two procedures, and the advantages of the new technique over the conventional one are examined.
