Abstract

PEREIRA, M. A. Stanojev; PUGLIESI, F.  and  PUGLIESI, R.. Neutron induced radiography: a technique to inspect the internal structure of thin samples. Braz. J. Phys. [online]. 2008, vol.38, n.3a, pp.346-349. ISSN 0103-9733.  http://dx.doi.org/10.1590/S0103-97332008000300007.

The present paper describes a radiography technique to inspect low thickness samples, on the order of micra. The penetrating radiation are charged particles generated by a lithium fluoride screen irradiated by thermal neutrons. The film used to register the images is a solid state nuclear track detector and the experimental conditions to obtain the best radiography are provided. A digital system for data acquisition and image processing was also used.

Keywords : Track detectors; Track [etch foils]; Radiography.
