Radiography is a method to visualize the inner structure of macroscopic samples. It is based on the principle of the
attenuation of radiation passing through matter, depending on the sample material and geometry. Besides the
well-known radiographic examinations with X-rays and c-rays, neutron radiography provides an important endorsement
to radiographic examinations in the "eld of non-destructive testing (NDT), as contrary to X-rays, neutrons are
attenuated by some light materials, as hydrogen, boron and lithium but penetrate many heavy materials. Neutrons are
even able to distinguish between di!erent isotopes and besides, neutron radiography is an important tool for the
investigation of radioactive materials. One of the key components of a radiography facility is the detector. Usually, it is
a two-dimensional, integrating imaging device. For neutron radiography applications requiring high quantitative
precision as well as for neutron tomography investigations, a CCD-camera-based neutron radiography detector has been
developed. It consists of a neutron sensitive scintillator screen, a nitrogen-cooled slow-scan CCD-camera and a mirror to
re#ect the light emitted by the scintillator to the CCD-camera. The whole assembly is placed in a light}tight enclosure.
This paper presents the basic principle of this detector system, the strategy for the selection of the individual detector
components, comparisons of the in#uence of the use of di!erent components on the properties of the whole imaging
device and results of the "rst test measurements.
