Abstract

Abstract

The activity of ²²⁴Ra in the seawater from the Xiamen Bay was determined by preconcentration with MnUz-fiber and successive emanation scintillation method of ²²⁰Rn.The profiles of ²²⁴Ra were applied to the estimation of the vertical eddy diffusion coefficient (K_z) at the several stations in the Xiamen Bay.The profiles of ²²⁴Ra and K_z arising therefrom make it possible to gain an insight into the pattern of the vertical diffusion of the waters in sea area studied and its spatial and temporal variations.These results will provide guidances for the study on the diffusion and transport of dissolved pollutant and estimation of self-purification capacity of the sea area studied.
