Dr. Kim Jeong-gi of the medical physics research team at the Southeast Atomic Energy Institute received the ‘Best Poster Award’ at the ’10th Korea-Japan Medical Physics Society International Conference’ held in Nagoya, Japan last month.
The topic is a study on the effectiveness of radiation therapy equipment using electron paramagnetic resonance spectroscopy and alanine dosimetry. (“Radiation therapy electron linear accelerator dose verification and calibration using EPR/alanine dosimeter” (First author: Jeong-gi Kim, Corresponding author: Young-rok Kang))
Dr. Kim said on the 22nd, “Radiation measurement using electron paramagnetic resonance spectroscopy/alanine dosimeter uses electron paramagnetic resonance (EPR) equipment to measure the signal of free radicals in alanine samples and determine the absorbed dose through this. “It is a method of calculating,” he said. “It has high accuracy and stability when measuring high doses of radiation, making calibration and measurement of radiation therapy devices easy.” By using this method, the quality control level of radiation therapy devices can be further improved.
Meanwhile, the Dongnam Institute of Atomic Energy Medicine acquired additional ‘KOLAS recognition’ in 10 test items for radiation and radioactivity measurement in January of this year, becoming the first in Korea to issue certified test reports for alanine dosimeter, teeth and food based on electron paramagnetic resonance analysis. there is.
In addition, through radiation exposure dose evaluation and research on radiation and radiation precision measurement technology, not only radiation therapy devices, but also radiation to soil, seawater, animals, plants, and food in the southeastern region where major facilities such as research reactors, Kori nuclear power plants, and heavy ion therapy devices are located. An impact assessment will also be carried out.
