Abstract

This article focuses on the transfer and behavior of radioactive iodine isotopes, specifically iodide (I⁻) and iodate (IO₃⁻), from seawater and seaweed to abalone (Haliotis discus hannai) in the marine environment near nuclear fuel reprocessing plants. Using a ^125I tracer, the study found that iodide is directly absorbed by abalone from seawater, whereas iodate is not absorbed directly but may be converted to iodide before uptake. Additionally, the transfer rate of ingested radioactive iodine from sea lettuce (Ulva Linnaeus) to abalone was significantly higher than from wakame (Undaria pinnatifida), likely due to differences in the chemical form of iodine in these seaweeds. These findings contribute to understanding the environmental impact of radioactive iodine (^129I) released from nuclear facilities on marine food sources.
