Nuclear Shielding Attenuation: concrete ordinary
Mass attenuation coefficients, linear attenuation coefficients, half-value layers (HVL), tenth-value layers (TVL), and buildup factors for gamma-ray and neutron shielding design. Covers lead, ordinary concrete, barite concrete, steel, water, polyethylene, borated polyethylene, and tungsten at gamma energies from 0.1 to 10 MeV. Neutron removal cross sections for fast and thermal neutrons. Sources: NIST XCOM database, ANSI/ANS-6.4.3-1991 buildup factors.
