Abstract
This paper focuses on the 210Po level of typical aquatic products in China.In 2016,aquatic samples were collected in two of the most important fishery area along the Yellow Sea coastal,Rongcheng of Shandong province and Lianyungang of Jiangsu province,210Po in 22 typical seafood species of 5 categories were analyzed and measured by the method of acid wet ashing and PIPS alpha spectrometer,whose detection limit was 2.2 × 10 2 Bq/kg fresh weight.The results show that 210Po level of the various seafood edible part ranges 1.17× 10 1-6.58× 10 Bq/kg fresh weight,generally the highest for shellfish and followed by crustaceans,whereas there are big differences between specific species of cephalopods,fish and algae,generally less than 10 Bq/kg fresh weight.There is a certain difference of the 210Po level in the samples from different sites,as Rongcheng indicates higher than that in Lianyungang.The 210Po concentrations in all kinds of seafood (except cephalopods) from the Yellow Sea in 2016 autumn are one time higher than those of global representative concentrations reported by UNSCEAR 2000.Compared with the results of seafood radionuclides survey in 1977-1978,210Po level in the Yellow Sea seafood samples is somewhat lower in this investigation.关键词
