Variations in radiocarbon concentration and sunspot activity

Abstract

Variations in cosmic-ray intensities will produce variations in C/sup 14/ production in the atmosphere. A comparison is made between variations in sunspot activity and fluctuations in C/sup 14/ concentration during the past 13 centuries. Although a definite conclusion is not reached, the evidence given suggests some correspondence between sunspot activities and C/sup 14/ concentration in the atmosphere. (auth)
