    Abstract

    The authors describe a method for absorbed-dose measurements of fast neutrons and gamma radiation in composite gamma-neutron fields by air-filled heterogeneous ionization chambers. The results obtained by heterogeneous and homogeneous ionization chambers are compared for measurements in water irradiated by fast neutrons from the U-120 cyclotron (the reaction 9Be(d, n)9B). It is shown that air-filled heterogeneous ionization chambers are favorably distinguished from homogeneous chambers by design simplicity with acceptable error (≈9%) for practical purposes.
