The Monte Carlo method has been used to determine the albedo of 1-Mev photons reflected from semiinfinite slabs of water, aluminum, copper, tin, and lead at various angles of incidence. The case histories of 67 photons were followed. For normal incidence the number albedo varies from 33 percent for water to 0.5 percent for lead, and the energy albedo from 5 percent for water to 0.1 percent for lead.
