In this work the measurement of neutron distributions along and normal to the axis of air filled ducts with different duct diameters pierced in ilmenite concrete have been carried out. The data show the dependence of the neutron doses on the duct length and diameter. The neutron distributions along the duct axis were compared with the corresponding distributions in solid ilmenite concrete. Semiempirical formulae have been derived fitting well with the experimental data obtained.
