摘要：

The results from a spectral analysis of production rate of 10Be cosmogenic isotope over the last 10000 years are considered. It is shown that the 10Be production rate is cyclic. Duration of the most powerful cycle is about 2300 years. In addition to this cycle, thousand-year variations in the 10Be production rate are observed. The thousand-year cycle could be due to the modulation of the cosmic ray flux by solar activity. © 2011 Allerton Press, Inc.
