Calculation of the Solar Activity Effect on the Production Rate of Cosmogenic Radiocarbon in Polar Ice

The propagation of cosmic rays in the Earth's atmosphere is simulated. Calculations of the omnidirectional differential flux of neutrons for different solar activity levels are presented. The solar activity effect on the production rate of cosmogenic radiocarbon by the nuclear-interacting and muon components of cosmic rays in polar ice is studied. It has been obtained that the $^{14}C$ production rate in ice by the cosmic ray nuclear-interacting component is lower or higher than the average value by 30% during periods of solar activity maxima or minima, respectively. Calculations of the altitudinal dependence of the radiocarbon production rate in ice by the cosmic ray components are illustrated.
