Abstract

Abstract

Radioo nuclides in the surface sediments in special biological population dropping amended soil collecing from Antarctica have been measured with spectrometer.The average contents of ⁴⁰K,¹³⁷Cs,²¹⁰Pb,²²⁶Ra,²²⁸Ra,²²⁸Th and ²³⁸U are 143, 7.56, 24.1, 3.65, 5.36, 4.15 and 6.5 Bq/kg.The specific activity of ²¹⁰Pb for the core samples in sea birds dropping amended soil,respectively from Ardley Island, have been measured.A ccording to the profiles of ²¹⁰Pb specific activity, we used CRS model to date the core samples.Which spans about 74 a(1928~2002).Base on the dating, we estimateth evelocity of deposition.Effece of the naturalr adionuclides treca on dating,relations between storage method of radionuclides and regional climate anomaly variation, and of under the construction of Antarctica have been distributed.
