On November 26–28, 2025, we participated in the 2025 Fall Conference of the Korean Association for Radiatopn Protection. 

Hyolee Kim presented “A Review of Radiation Simulation for the Verification of Space Radiation Shielding Materials".

Sehyun Cho and Hyegyo Lee delivered a presentation titled “A Review of Cosmic Radiation Shielding Materials Based on OPC and geopolymer: Gamma Irradiation Effect ".

Yueun Kang presented “Evaluation of Geopolymer as Primary Cosmic Radiation Shielding materials: A Review ".

In addition to their presentations, the team participated in workshops related to their research interests and attended various sessions, gaining valuable experience and insights.

Hyolee Kim was awarded the Best Poster Award at the 2025 Fall Conference of the Korean Radioactive Waste Society for her work titled:

“Development of NiAl LDH-based Bead Sorbent for Efficient Iodide Removal under Aqueous Condition”
(with Yerim Kim and Prof. Jaehyuk Kang)

Her research was recognized for proposing an effective NiAl LDH-based bead sorbent capable of removing iodide under aqueous conditions.
