Abstract
A scintillation-based detection device and method for continuous monitoring of flowing liquids for the presence of radionuclides. A side-stream pipe directs a portion of the monitored liquid from the main flow transfer pipe through and/or around the detector. Within the side-stream pipe is a scintillation detector assembly, having) either a nested-cylindrical or stacked-element shape. The real-time to near real-time detection capabilities are influenced by the total surface area of the detector assembly. The detectors are operated in anti-coincidence mode to distinguish pure beta-emitters from beta-gamma emitters and from pure gamma events. A gross beta count, gross gamma count, or some combination may also be determined.
