Zusammenfassung:A nuclear reactor radioactive emission monitor measures quantities of a selected radioactive component in a stream of radioactive fluid. The device comprises two fluid paths with each path having a filter to absorb a radioactive component while passing the remainder of the stream of radioactive fluid; each fluid path also has a detector to measure the level of radioactivity emitted by the retained radioactive component in the two filters. A valve alternately directs the stream of fluid from the first fluid path to the second fluid path while simultaneously purging the remainder of the fluid from the non-selected fluid path. The output of one or more of the detectors is integrated as a function of time to indicate any increase in the radioactivity emitted by the radioactive component retained by the filter.
