We are proud to announce that Song Min-seo received the Excellent Presentation Award at the 2025 Autumn Meeting of the Korean Association for Radiation Protection (KARP), held from November 26 to 28, 2025.

The award-winning presentation was titled "Contamination Mapping Using a Lightweight UAV-mounted Gamma-ray Imaging System." It was highly recognized for its excellence and selected as an outstanding paper among the oral presentations. This achievement highlights our lab's commitment to advancing radiation detection and mapping technologies through innovative research.

We are pleased to announce that our research team’s paper, titled "Comparison of Characteristics of Gamma-Ray Imager Based on Coded Aperture by Varying the Thickness of the BGO Scintillator," was honored with the 2025 Best Paper Award by the Korean Association for Radiation Protection (KARP) on November 27, 2025.

This research, authored by Seoryeong Park, Mark D. Hammig, and Manhee Jeong, has been highly recognized for its significant contribution to the field of radiation detection by providing a rigorous comparative analysis of how BGO scintillator thickness influences the performance of coded aperture-based gamma-ray imagers. This prestigious award from KARP underscores our lab's commitment to technical excellence and innovation in radiation imaging and protection. We extend our warmest congratulations to the researchers for their dedication and outstanding achievement, and we will continue to strive for excellence in our future research endeavors.

The institute hosted a workshop on environmental radioactivity analysis trends and the latest automated radionuclide separation technology.

Experts from the Korea Institute of Nuclear Safety (KINS) were invited to lead sessions on the measurement and analysis of Sr-90 samples. 

Our laboratory's Team SIGMA was honored with the Grand Prize at the "3rd Radiation Technology Creative/Convergence Idea Competition" hosted by the Korea Association for Radiation Application (KARA) on August 26.

Team SIGMA developed a portable device capable of visualizing radioactive contamination in 3D space by integrating gamma-ray imaging technology with 3D LiDAR. 

Following this achievement, the team was further distinguished by receiving the Minister’s Award from the Ministry of Science and ICT at the KARA 40th Anniversary Ceremony held on September 30. This series of awards recognizes the team's innovative contribution to the field of radiation safety and visualization technology. 

From August 11 to 12, 2025, the 2025 Environmental Radiation Detection Technology Exchange Meeting was held to establish a collaborative foundation through expert networking and the sharing of technical expertise in gamma-ray imaging systems.

The event brought together specialists from the Korea Institute of Nuclear Safety (KINS), the Korea Institute of Nuclear Nonproliferation and Control (KINAC), the Korea Atomic Energy Research Institute (KAERI), and Jeju National University.

Following a comprehensive information exchange session between the participating institutions, live demonstrations were conducted featuring gamma-ray imaging systems developed by Jeju National University, integrated with various robotic platforms including UAVs, UGVs, and quadrupedal robots. 

May 9, 2025, representatives from the Republic of Korea Army Chemical, Biological, and Radiological (CBR) School visited to exchange technical information regarding the gamma-ray imaging systems and integrated robotic platforms under development at our laboratory.

The visit focused on discussing the operational scope of gamma-ray imagers in the event of nuclear accidents, as well as exploring their potential applications for military defense and specialized reconnaissance missions.

The event concluded with a live demonstration of our laboratory's unmanned systems—including UAVs, UGVs, and quadrupedal robots—fully integrated with advanced gamma-ray imaging technology. 

The Research Institute of Nuclear Science and Technology at Jeju National University has been officially accredited as an International Accredited Testing Laboratory by the Korea Laboratory Accreditation Scheme (KOLAS).

KOLAS is a government-run accreditation system that evaluates the quality management systems and technical capabilities of testing laboratories in accordance with international standards (ISO/IEC 17025). This accreditation (Accreditation No.: KT1043) officially recognizes the institute’s technical competence and the reliability of its measurement results on a global level.

With this designation, the institute is now authorized to issue internationally recognized test reports. This will enable more systematic and credible radioactivity monitoring for various local resources, including agricultural and marine products, groundwater, and tap water in the Jeju region, further ensuring public safety.

The Radioactivity Sample Pre-treatment Lab at the Research Institute of Nuclear Science and Technology has been officially certified as an "Excellent Safety Management Laboratory" by the Ministry of Science and ICT (MSIT).

This certification is awarded to research facilities in universities and institutes that demonstrate superior safety management standards and proactive safety practices.

Following its previous certifications in Pharmacy and Biomaterials in 2023, Jeju National University (JNU) has achieved this additional accreditation in December 2024, further solidifying its commitment to a secure research environment.

On February 14, 2025, our laboratory was honored with the Research Excellence Award for its outstanding academic achievements within the Jeju National University BK21 Education & Research Group.

BK21 is South Korea’s flagship national project led by the Ministry of Education and the National Research Foundation. It aims to foster world-class research universities by providing financial support and research infrastructure to graduate students and researchers, enabling them to focus on pioneering studies.

This award recognizes the high-quality research output produced by our team under the BK21 initiative. We will continue to strive for academic innovation and technical leadership in the field.
