Research Abstract

The records of cosmogenic nuclides in Dome Fuji ice core, covering 720 kyr, wereanalyzed by means of Accelerator Mass Spectrometry. By analyzing several prominentgeomagnetic events, Laschamp, Blake, Iceland Basin, in detail, the records ofcosmogenic nuclides, especially Beryllium-10, were found to be excellent indicator ofthe variation of cosmic ray intensity.
