文摘

224Ra concentrations in the coastal sea water of western Taiwan Strait in winter were measured using Mn-fiber adsorption—successive emanation scintillation method. 224Ra activities in the seawater of the western Taiwan Strait varied from 0.90 to 16.25?Bq/m3 with an average of 4.60?Bq/m3. The horizontal and vertical distributions of 224Ra were studied. The distributions of 224Ra in the surface water decreased gradually with increasing distance offshore. The apparent horizontal and vertical eddy diffusion coefficients estimated from the one dimensional steady state model of 224Ra were (5.0-5.4)?×?106cm2/s and (4.0-1.7) cm2/s, respectively.
