The state-of-the-art for the continuous monitoring of /sup 14/C, /sup 129/I, and /sup 85/K was evaluated. Published methodology and developmental programs at the Idaho Chemical Processing Plant are summarized. A sequential monitor is proposed where all forms of /sup 14/C and /sup 129/I are catalytically converted to a single form (CO/sub 2/ or I/sub 2/) and separated from interferences by selective permeation. Lastly, /sup 85/K is monitored with a beta detector mounted in a flow chamber. A developmental program for extending the state-of-the-art is outlined. 6 figures, 6 tables.
