ActiveDetermination of 131I in marine sediment—β counting method
海洋沉积物中碘-131的测定 β计数法
Application Summary AI generated
This standard specifies the β counting method for determining the concentration of iodine-131 (131I) in marine sediment samples. It is applied in environmental monitoring and radiation protection contexts, particularly for assessing radioactive contamination in coastal and seafloor sediments following nuclear accidents or routine discharges from nuclear facilities. The method provides a technical basis for marine radioactivity surveys and environmental impact assessments.
