✦ Synopsis
Numerical simulations of production rates for cosmogenic 10 Be, 26 Al and 14 C in well-documented samples from the meteorite Knyahinya and the Apollo 15 deep core were performed using the MCNPX (Monte Carlo N Particle eXtended) code for cosmic-ray interactions. Comparisons of experimental measurements and our numerical simulations were done to test our calculations and show that the numerical simulations reproduce well experimental measurements. The effective fluxes of GCR proton determined from our comparisons are important parameters for future calculations. Additional measurements of some radionuclide activities and of cross sections for neutron-induced reactions are needed.
