Abstract : Curves are presented which enable one to determine the neutron number current, number flux, energy, and dose albedos as functions of the hydrogen content of a shield material. The curves are given for eight incident energies: 0.1, 0.25, 0.50, 1.0, 2.0, 3.0, 5.0, and 14.0 Mev and four incident angles: 0, 30, 45, and 70 degrees for each energy. A method is presented by means of which one can calculate changes in neutron albedos caused by hanges in cutoff (or effective cutoff) energy. (Author)
