| Research Abstract |
Cosmogenic Radio Nuclides, Be-10, Al-26, and Cl-36 in Antarctic ice core (spanned over 720 kyr) were systematically measured by means of Accelerator Mass Spectrometry. As a result, many cosmic ray events in multiple time scales were found. Most of observation indicated the strong correlation between the variation of production rate of above nuclides and solar activity, geomagnetism and climate change of mid-latitude region.
