Abstract

The results of an investigation on the spatial variations of neutron flux using neutron-charged particle converter materials and solid state nuclear track detectors in a thermal neutron irradiation site are reported. In this context, three neutron beam maps have been established and analyzed. Neutron flux cartographies performed with the BN1 converter, which has been found to be more sensitive to neutron flux variations than the lithium tetraborate converter, have allowed location of neutron concentration areas. The results of average neutron flux measurements obtained by means of the SSNTD technique are in good agreement with those obtained using the conventional technique of neutron flux measurement by activation of foils.
