GSU DYMO

GAMMA SPECTROMETER FOR DYNAMIC MONITORING

The gamma spectrometer GSU DYMO is a versatile measurement equipment based on big dimensions NaI(Tl) detectors, designed to perform gamma spectra acquisition in a dynamic configuration.

This means that either the detector or the object to be monitored is moving. This requires a considerably fast and accurate data acquisition, and a high counting efficiency.

The proprietary processing software allows to perform this kind of analysis, through the definition of ROIs in the gamma emission spectra and the possibility to set the frequency of the instant spectra acquisition (1 s typical). A moving average algorithm is applied to the acquired spectra, in order to better identify sudden spectrum variations above the background. This way, the software can determine the net integral counts for each ROI and even quantify the activity of each radio-isotope, for example 241Am, 137Cs, and 60Co.

 
GSU DYMO is the perfect solution for applications that require a simple, reliable and versatile instrument to perform gamma spectrometric analysis. Some of these applications can be for example:

  • aerial monitoring of a territory portion performed with helicopters or drones
  • area monitoring performed with vehicles (either ground or water)
  • monitoring of materials carried by conveyor belts

The management software has an integrated utility for energy calibration and temperature correction, which allows to “follow” the natural K-40 peak and to correct the analysis compensating the temperature effects.
