The UnderSec Project was in the spotlight at the HNPS2025 International Conference, held on June 6th and 7th, 2025, where leading researchers and professionals gathered to discuss cutting-edge applications of ionizing and non-ionizing radiation. The conference, renowned for its focus on experimental and theoretical physics, engineering, and industry, provided an ideal platform for presenting the latest advancements of the mini-KATERINA radioactivity sensor.
Poster Presentation: Validating mini-KATERINA in Controlled Environments
HCMR’s poster session drew the attention of over 50 participants from research institutes, universities, and industry. The poster highlighted the development and operational validation of the mini-KATERINA sensor in controlled environments, such as air and water tanks. A key focus was the calibration of the detection system in 4π geometry, ensuring accurate and comprehensive measurements. The presentation emphasized the importance of small, fast-response detection systems for ship hull inspection—a crucial need for modern maritime safety and security.
Oral Presentation: Real-World Deployment and Impact
In a well-attended oral session with around 80 participants, HCMR presented the latest results from deploying the mini-KATERINA sensor in both controlled and real-world environments. The talk addressed the critical role of radioactivity monitoring in ports and during ship hull inspections, especially in scenarios involving potential radiological incidents such as ‘dirty’ bombs or ‘orphan’ sources. The presentation included a comparative analysis of experimental data and simulation results, demonstrating the system’s capability to quantify radioactivity and respond rapidly to security threats.
Advancing Project Objectives and Engaging Stakeholders
Both sessions underscored the UnderSec Project’s commitment to developing compact, efficient, and reliable detection technologies for maritime applications. By targeting research institutes, universities, and industry stakeholders, the project is fostering collaboration and innovation in the field of nuclear safety and environmental monitoring.
The strong engagement at HNPS2025 highlights the growing recognition of the mini-KATERINA sensor’s potential to transform ship hull inspection and port security, ensuring safer seas for all.
