〇 On-site expert training
- The Korea Human Resource Development Institute for Health and Welfare provides training on food radiation monitoring to radiation analysts at institutions that inspect food radiation. If a lecture request is made at this institution, I am willing to participate as a training instructor on the analysis of food radioactivity and to educate field experts.
- In addition, gamma-radioactive inspection systems and other nuclide screening systems were established in the project. We signed a two-year maintenance and repair contract with the equipment purchaser for each equipment. If there is a problem with the construction equipment, Cheongju University plans to contact the equipment manufacturer to facilitate the maintenance and repair of the equipment.

- Improvement of inspection ability and securing reliability of inspection results by education of on-site experts in food radiation field
- In the event that the consumption of marine products can drop sharply due to the vague concern about the contamination of food radioactivity after the nuclear accident in Fukushima, the consumption of food radioactive safety management through education and promotion on the safety management of food radioactivity will be consumed. Activation contribution
〇 Enhance the work efficiency of workers in related organizations by expanding the inspection equipment of food radiation, the performance of inspection equipment and improving the accuracy of inspection.
- Improved inspection ability of food radioactivity (4.3 times) by converting manual inspection of food radioactivity(734 samples) to automatic inspection (3,153 samples)
- Alpha-beta radioactivity inspection of food will be expanded from KFDA to 4 local KFDA to lay the groundwork for eliminating bottleneck of inspection.
- Strengthen inspection capability through education and proficiency evaluation
〇 Preventing social chaos by transparently presenting food monitoring results to food consumers nationwide
- Established a foundation to inspect alpha and beta radiation in foods and prepared solutions to consumers' needs by expanding the scope of safety management
〇 Promotion of safety management of food radioactivity and development of educational materials, shifting to safety awareness of food radioactivity and relieving public anxiety
- In a situation where there is vague anxiety due to lack of understanding of safety management of food radioactivity and radioactivity standards, consumers' anxiety is resolved by actively training and promoting safety management of food radioactivity and inspection standards on radioactivity.
