FOOMON is a portable fully-integrated instrument specifically conceived for screening of I-131, Cs-134 and Cs-137 accumulated in food samples. Its “on-the-field” design allows deploying the device in any kind of situation, such as routine campaigns or emergency procedures.

The whole device is self-contained in a portable high-IP-grade technical case, for an overall weight < 25 kg. The food samples are to be placed in 500 ml Marinelli beakers, which then are lodged inside a 1 cm thick lead shielding well upon the detector’s end cap. The complete setup and deployment of the system requires less than 5 minutes.

The User can manage FOOMON through the user-friendly control and analysis software installed on the embedded panel PC, automatically calculating the specific activity and the Minimum Detectable Concentration (MDC) of the sample (in Bq/kg). Data are stored locally and can be analysed and downloaded with dedicated software routines.

The measured activity concentration is compared with isotope-specific and food-group-specific alarms. In the case of an alarm, the measurement output is clearly labelled and the alarm status is clearly displayed on the software, which also activates the acoustic alarm.

The counts-to-activity-concentration conversion coefficients are calculated by means of dedicated Monte Carlo calculations.

The MDC achievable in 1 minute, with an average indoor background (150 nSv/h), is as low as about 150 Bq/kg for Cs-137 and Cs-134, and about 90 Bq/kg for I-131. Under the same conditions, MDC as low as about 30 Bq/kg for I-131, and about 40 Bq/kg for Cs-134 and Cs-137, can be achieved in about 10 minutes.

If enabled, the automatic background subtraction subroutine allows further lowering MDC and measurement uncertainty without increasing the counting time.

HERMES GSU is a portable gamma spectrometry system designed for rapid and precise in-field analysis of environmental samples. As part of the HERMES product line, 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 and autonomous operation make it ideal for both routine monitoring and emergency response scenarios.

Samples can be directly collected from the field, placed in 500 ml Marinelli beakers, and inserted into the built-in 1 cm lead-shielded well, minimizing background radiation for immediate, on-the-spot, low MDC analysis, and enhancing measurement accuracy and sensitivity. 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 (relying on natural background only, thus not requiring any radioactive reference source). 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. Custom calibration curves can be provided upon request.

The ELSE NUCLEAR AERIS is a rugged, field-ready portable gamma spectrometric system engineered for immediate, in-situ analysis of radioactive contamination on air particulate sampling media. Distributed in Canada by SciWise, the AERIS system eliminates sample transport delays to off-site laboratories by providing fast radionuclide identification and activity quantification directly in the field.

Deployable in fixed stations or mobile configurations, AERIS directly accepts standard particulate filters and charcoal cartridges up to 60 mm in diameter. Featuring a high-sensitivity scintillation detector enclosed in a lead shield, the instrument delivers lab-grade spectrometric accuracy even in challenging, high-background radiation environments.

The ELSE Nuclear THYMON is a compact, high-sensitivity thyroid monitoring system engineered for rapid, reliable detection of Radioiodine (I-131) contamination during radiological emergencies and population triage.

Combining a collimated NaI(Tl) scintillation detector with advanced silicon photomultiplier (SiPM) readout electronics and an intuitive rugged tablet, THYMON delivers high-accuracy screening in under two minutes without requiring nuclear physics expertise. Fully compliant with IEC 61582 standards, it is suitable for nuclear emergency response teams, first responders, hospital radiation safety officers, and civil defense agencies.

FULL-SCALE PERFORMANCE. DEPLOYED WHERE IT MATTERS.

Emergency responders, health physicists, and homeland security teams require radiation detection that delivers laboratory-grade sensitivity directly to the field. The HERMES Rugged Mobile Radiation Survey Unit by ELSE NUCLEAR combines modular detector architectures, automated background calibration, and real-time mapping into a single, high-durability system built for rapid on-site deployment.

Whether configured as a handheld tactical unit or installed as a vehicle-mounted mobile scanning array, HERMES offers unmatched measurement versatility in critical radiation monitoring scenarios.
