Development of a Floating Radiation Measurement System for Underwater Readings in the East Sea of Korea

Development of Continuous Monitoring System for Seawater Discharging

“…This 0.0162 cps/photon value was obtained from the previous computational simulation result. Using a Cs-137 gamma yield of 0.85 cps/Bq, sample container volume of 2 L, and measurement time of 600 sec, 4.1 Bq/L was obtained by calculating using the Currie MDA equation below (1) (Joung, Ji, and Choi, 2023):…”

“…Apart from the ocean current-driven spread of contaminated seawater from the Fukushima nuclear power plant accident, public concern has been raised about the spread of radioactive contamination by human intervention. Representative cases that have been pointed out include contamination from the discharge of ballast water from ships entering the Republic of Korea from the vicinity of the Fukushima accident area (Min et al, 2021), and possible contamination from the discharge of seawater from vehicles entering the country, namely those transporting live fish (Joung, Ji, and Choi, 2023). In this paper, we introduce the design, development, and implementation of a continuous radiation measurement system to inspect all seawater discharged from live fish transport vehicles entering the Busan port, Korea.…”
