摘要
Application of CR-39 for the characterization of the neutron distribution in the neutron radiography channel of the Algerian reactor NUR is reported. The neutron detection assembly, consisting of a boron neutron-charged particle converter in contact with CR-39, was used to map the neutron flux over a 10.5 x 21 cm(2) area. The relationship between the CR-39 track density and the neutron flux has been established by a mathematical development of the detection and revelation conditions for the charged particles emitted in the neutron-induced reactions in the converter. The degree of homogeneity of the neutron field has been determined and the higher and lower neutron fluxes have been situated. (c) 2008 Elsevier B.V. All rights reserved.
