New development: ARGOS – Advanced Radiation Gamma Observation System
Medusa Radiometrics is developing a new generation of gamma ray sensors through the ARGOS project (Advanced Radiation Gamma Observation System). The project aims to create both mobile and stationary gamma spectrometers using innovative plastic scintillation crystals combined with advanced embedded software based on machine learning.
Our current gamma ray systems rely mainly on scintillation crystals such as CsI. These crystals are accurate and robust, but they are also expensive and often sourced from geopolitically sensitive regions. Plastic scintillators can potentially offer a more affordable and rapidly available alternative and reduce dependence on critical raw materials. However, they produce lower resolution signals compared to traditional crystals. The ARGOS project therefore focuses on integrating AI driven analysis methods to reliably interpret these signals, enabling accurate identification of natural radionuclides such as potassium, uranium and thorium, as well as the detection of unknown or artificial sources.
Two working prototypes will be developed and tested: a stationary sensor for long-term field monitoring and a mobile sensor for rapid mapping. These systems will be validated through simulations and extensive field trials under real environmental conditions. The technology will support applications in sustainable agriculture, environmental monitoring, climate adaptation, and emergency response to radioactive incidents.
The project is co-funded by the EU through the Just Transition Fund (JTF) as part of the VIA Groningen 2025–2026 programme, supporting innovation and economic development in Northern Netherlands.
