Curves of neutron dose transmission versus thickness are presented for laterally infinite slabs of several common materials for neutrons incident at several fixed energies and angles. The materials are water, polyethylene borated, iron, concrete, Nevada Test Site soil area 7, dry and 100 percent saturated, laminated slabs containing one inch of iron on the outside, a variable thickness of iron on the inside, and 3, 6, 9, or 12 inches of polyethylene sandwiched between the layers of iron. The neutron source energies are 0.5, 1, 2, 3, 5, and 14 MEV the incident angles are 0 degrees, 30 degrees, 45 degrees, and 70 degrees.
