Dr. Kim Jeong-gi of Dongnam Institute of Radiological & Medical Sciences Wins Excellence Poster Award at Korea-Japan Medical Physics Society Meeting

Recognition of Excellence in Research on the Effectiveness Evaluation of Radiation Therapy Devices

Dr. Kim Jeong-gi of the Medical Physics Research Team at the Dongnam Institute of Radiological & Medical Sciences (Director Lee Chang-hoon) recently received the Excellent Poster Award at the 10th Korea-Japan Medical Physics Society International Conference held in Nagoya, Japan from September 20 to 22, for his research on the efficacy evaluation of radiation therapy devices using Electron Paramagnetic Resonance Spectroscopy and alanine dosimeters.

Dr. Kim presented a paper titled “Dose Verification and Calibration of Electron Linear Accelerators for Radiation Therapy Using EPR/Alanine Dosimeters (First author: Kim Jeong-gi, Corresponding author: Kang Young-rok),” which was recognized for its excellence in the field of radiation therapy device measurement.

Radiation measurement using Electron Paramagnetic Resonance Spectroscopy and alanine dosimeters involves measuring free radical signals within alanine samples using Electron Paramagnetic Resonance (EPR) equipment and calculating the absorbed dose accordingly. This method is characterized by high accuracy and stability in measuring high radiation doses, making it suitable for calibration and measurement of radiation therapy devices.

Lee Chang-hoon, Director of the Dongnam Institute of Radiological & Medical Sciences, stated, “The results of this study are expected to further enhance the quality control level of radiation therapy devices. In particular, evaluating the accuracy of dose measurement of radiation therapy devices using alanine dosimeters in the treatment field is anticipated to contribute to high-dose treatment planning.”

In January of this year, the Dongnam Institute of Radiological & Medical Sciences obtained additional KOLAS accreditation for 10 test items related to radiation and radioactivity measurement, becoming the first in Korea to issue accredited certificates for alanine dosimeters based on Electron Paramagnetic Resonance analysis, as well as for teeth and food.

Furthermore, by continuously conducting research on radiation exposure dose assessment and precision measurement technologies for radiation and radioactivity, the institute plans to promote radiation impact assessments on humans in the Dongnam region, where major facilities such as research reactors, Kori Nuclear Power Plant, and carbon ion therapy devices are located, including soil, seawater, flora, fauna, and food.
