Seasonal variations of 228Ra/226Ra and 228Th/228Ra ratios in surface water from the eastern East China Sea

A total of 30 surface water samples were collected at 2 sites on the east side of the East China Sea (ECS) during 2008–20f0, and 226Ra, 228Ra, and 228Th activities were measured using low-background γ-spectrometry. The 228Ra/226Ra and 228Th/228Ra activity ratios of the samples exhibited notable seas...
