An Attempt to decrease anisotropic emissions of neutrons from a cylindrical $$^{241}$$Am-Be-encapsulation source

Kowatari, Munehiko; Tanimura, Yoshihiko   ; Yoshizawa, Michio  

An attempt to decrease the anisotropic emissions of neutrons from a cylindrical $$^{241}$$Am-Be encapsulated X3 source was conducted out by Monte Carlo calculations and experiments. Influence of metal materials and shapes of the external casing to the anisotropy factor were focused on. Results obtained by calculations using MCNP4C implied that a light and spherical-shaped casing decreases the anisotropic emission of neutrons. Experimental results using the spherical-shaped aluminum protection case also revealed that the anisotropy factor was close to 1.0 with wide zenith angle ranges.
