Abstract:

A study was conducted to determine the effect that varying the length and diameter of a straight cylindrical duct has on the neutron radiation streaming through the duct. An experi ment was set up in which a polonium-beryllium source was located on centerline in the mouth of an aluminum duct penetrating a water slab. The resulting data were analyzed by use of two Monte Carlo procedures developed to analyze radiation streaming through cylindrical ducts. Results of additional calculations are shown to indicate the possibility of extending the experi mental findings to duct problems involving dif ferent source energy and angular distributions and different shielding materials.
