HERMES GSU is a portable gamma spectrometry system designed for rapid and precise in-field analysis of environmental samples. It features a rugged, modular, and self-contained design housed in a high IP-rated technical case, ensuring durability and reliability in demanding conditions.
HERMES GSU quantifies isotope activity concentrations based on a rich built-in, yet fully-editable, isotope library. Its portability make it ideal for both routine monitoring and emergency response scenarios. The software user interface is installed on a control tablet.
Samples can be placed in 500 ml Marinelli beakers, and inserted into the built-in 1 cm lead-shielded well, minimizing background radiation for on-the-spot, low MDC analysis. The system automatically calculates activity concentrations, making it a powerful tool for in-situ, laboratory-grade measurements.
HERMES GSU features advanced routines for gain stabilization, dead time correction, and automatic energy calibration.
Efficiency calibration curves are generated using validated Monte Carlo simulations. Predefined efficiency curves are available for different sample matrices, including soil, water, and foodstuffs, across various densities.
An automatic anomalous background and anomalous peaks detection algorithm continuously surveys the system. If deviations exceed the expected statistical range, the system alerts the operator, indicating a potential anomaly.
