| Abstract: | core samples were collected from the different coastal areas of the East China Sea and then their 137 Cs or 210 Pb profiles were measured separately in the lab By 137 Cs time marks and the excess 210 Pb methods, the recent sedimentation of the typical coastal geomorphologic units were studied In addition, the regional distribution of the 137 Cs activity and the integral flux of the cores , and its implication to the coastal environment were also analyzed |

| Keywords: | East China Sea coast core samples 137 Cs and 210 Pb profiles sedimentary environment |
