OSTI ID:4001551
A facility for investigating neutron shielding is described, and some preliminary findings on the streaming of neutrons in ducts of protective shelters are presented. The experimental results are compared to a simplified theoretical treatment using the albedo approach. Dose measurements were obthined in a 3 x 3- ft concrete duct for thermal, 2.5-Mev, and 14.7-Mev neutrons using a 12-in. spherical energy-independent dosimeter. In the second leg, for all energies, the dose was found to have a higher drop-off than the theory predicted. Reasons for the discrepancy are examined, and a comparison of effective albedos is made for various energies. (auth)
