GammaTrend

Remote Monitoring Software package

H3D^® GammaTrend provides detailed isotopic trends with HPGe-quality quantification performance. When using a GammaTrend server in conjunction with H3D detectors, data for locations of interest can be viewed in real time for both short- and long-term tracking of isotope activity.

Monitoring Ag-110m at Palisades

H3D monitored Ag-110m at Palisades Nuclear Power Plant using the S100 and GammaTrend. Water samples from the facility's chemistry department showed a decreasing concentration for Ag-110m, while H3D GammaTrend showed the local concentration of Ag-110m increasing by almost 3 times. Internal smears of the pipe of interest (shown to the right) confirmed the H3D Ag-110m results, showing that using real-time isotopic trending with H3D can potentially be more effective than chemistry samples.
