Based on the analytical solution of the cosmic-ray propagation recently we have obtained, we apply it for the radioactive secondaries, such as 10 Be. We assume our Galaxy is boundaryless in both longitudinal and the latitudinal directions, and the diffusion coefficient depends on the rigidity in the form of ∝ v Rα , and alsoon the spatial coordinate r (r, z ) in the form of the exponential type. We compared the present numerical results with those obtained by recent experiments, and found the Galactic parameters thus estimated, such as the diffusion coeffeicient and the gas density are consistent with those expected from B/C and/or sub-Fe/iron ratio, and the diffused γ -rays.
