The new data on 239+240Pu, 238Pu, 241Pu, 241Am vertical distribution in the deep western Black Sea sediments was analyzed. The sediment dating, obtained by means of 238Pu/239+240Pu activity ratio vertical distribution, suggested the upper 3 cm layer of sediments to be formed during 27 years after the Chernobyl accident and the deeper layers to be formed earlier in pre-Chernobyl time (before 1986). The whole data set on profiles of radionuclides studied was shown to reflect the history of their input into the basin and elimination of t
