Can Neutron Beam Components and Radiographic Image Quality be Determined by the Use of Beam Purity and Sensitivity Indicators?

Abstract

In the Euratom Neutron Radiography Working Group Test Program beam purity and sensitivity indicators, as prescribed by the ASTM E 545-81 were used together with the NRWG beam purity indicator-fuel and calibration fuel pin. They were radiographed together at neutron radiography facilities of the European Community. The direct, transfer and track-etch methods using different film recording materials were used. Neutron beam components were calculated from film density measurements under the beam purity indicators and radiographic image quality was assessed by visual examination of the sensitivity indicator. Results obtained under the NRWG Test Program are summarized and compared.KeywordsThermal NeutronSensitivity IndicatorVisual ExaminationNeutron BeamFilm DensityThese keywords were added by machine and not by the authors.
