SHIELDING PROPERTIES OF FERROPHOSPHORUS CONCRETE AS A FUNCTION OF TEMPERATURE
An investigation was conducted to determine the shielding properties of ferrophosphorus concrete at temperatures up to 320 deg C for neutrons and gamma radiations. Ferrophosphorus concrete was selected because of its high density and possible use in biological-shield construction. The neutron and gamma attenuation properties of ferrophosphorus concrete were determined experimentally. The thermal and resonance fluxes are based on gold-foil activation while the fast flux was determined using the S/sup 32/(n,p)P/sup 32/ threshold reaction. The gamma attenuation was measured with ionization chambers. The tests indicate that the ferrophosphorus concrete could be used as a biological shield. lt should be pointed out that, under the conditions under which the fermophosphorus concrete was tested, there are other concretes that could be used which would be more efficient as well as more economical.
