A flow-cell detection system was developed utilizing a coincidence circuit and tested with BaF{sub 2}, CaF{sub 2}:Eu and scintillating glass. The coincidence detection system reduced the background from {approximately}200 cps to {approximately}0.5 cps. The detection efficiencies for these cells ranged from 0.38 to 0.66 for {sup 45}Ca beta particles (E{sub max} = 0.257 MeV) and from 0.45 to 0.52 for {sup 233}U alpha particles (E{sub {alpha}} = 4.8 MeV). The minimum detectable activity was calculated for a 30 s count time and determined to be in the range of 1-2 Bq.
