资源简介：
Atmospheric nuclear explosions during the period from the 1940s to the 1980s are the major
anthropogenic source of plutonium (Pu) in the environment. In this work, we analyzed fg g-1
levels of artificial Pu, released predominantly by atmospheric nuclear weapons tests. We
measured 351 samples which collected a 78 m-depth fire core at the site of GV7 (S 70°41
´17.1", E 158°51´48.9", 1950 m a.s.l.), Northern Victoria Land, East Antarctica. To determine
the Pu concentration in the samples, we used an inductively coupled plasma sector field
mass spectrometry coupled with an Apex high-efficiency sample introduction system, which
has the advantages of small sample consumption and simple sample preparation.
