The hardening effects of hydrogenous and nonhydrogenous filters on a p(66)Be(49) neutron beam have been investigated. It was found that all materials studied, Teflon, aluminum, lead, steel, and polyethylene, harden the neutron beam, albeit polyethylene to a greater extent. Relationships were found to exist between the attenuation of a filter and its hardening effect, and also between the build-up characteristics and the depth for half-maximum dose of the hardened beams.
