Dissolved ¹³⁷Cs, ^239.240Pu, ²³⁸Pu and ⁹⁰Sr contents in winter and spring of the Yellow Sea were determined to describe the distribution of artificial radionuclides. Surface water samples (100 liter) were collected by using a submerged pump, and subsurface samples (>10m depth) were collected using a 10L Niskin water sampler mounted to the Rosette sampler. The levels in the surface water ranged between 1.78～3.38 mBq kg^-1 for ¹³⁷Cs, 2.17～13.35 μBq kg^-1 for ^239,240Pu, and 1.97～3.96 mBq kg^-1 for ⁹⁰Sr, respectively. In particular, the concentration of ^239.240Pu were 1/10 of those in the vicinity of Changjiang estuary (61～83 μBq kg^-1). The difference of ^238.240Pu concentration between surface and bottom water was <3.0 μBq kg^-1in the Yellow Sea. It suggests that in the Yellow Sea which has shallow and high suspended sediments, ^239.240Pu is preferentially removed from the water columm. The water column inventory of ^239.240Pu in the Yellow Sea constitute about 0.7～0.9 % of the estimated fallout input to the area. The activity ratios of ^239.240Pu/¹³⁷Cs and ¹³⁷Cs/⁹⁰Sr ranged between 0.001～0.005, 0.79～1.65, respectively, and similar to those of open ocean which global fallout is the only source of artificial radionuclides. Therefore, it suggests that most of these artificial radionuclides in the Yellow Sea may be controlled by the atmospheric input.
