The main application of GSU is to analyse the spectrum of the gamma emissions of radioisotopes contained in small samples, either coming from foundry casting process checks, air particulate filters, metal by-products, geological samples, food, and other materials. Analysis of liquid samples contained in Marinelli beakers is also possible. The system includes a standard sample holder designed for foundry casting samples.
The user can define specific regions of interested (ROIs) through the ELSE NUCLEAR software (installed on the provided PC), and thus determine the sample specific partial and total activities (Bq/g). Isotope identification analysis can be provided optionally.
The GSU DYMO version is designed to perform gamma spectra acquisition in a dynamic configuration, which 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 efficiency. The proprietary software allows to perform this analysis, through the possibility to set the frequency of the spectra acquisition (1 s typical). A moving average algorithm is applied to the acquired spectra to better identify sudden spectrum variations above the background. GSU DYMO is the perfect solution for applications that require a simple, reliable and versatile instrument to perform gamma spectrometric analysis, such as:
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
