Abstract:
The present work examines two different geometric configurations and three different lining materials that are suitable for thermal neutron radiography purposes based on a 241Am/Be neutron source. The same source was also used for fast neutron radiography. Appropriate collimators were simulated for each of the radiography modes, comparing the effectiveness of Cadmium, Gadolinium, and Boral as lining materials for thermal neutron radiography and evaluating the efficiency of Iron and Tungsten as interior wall materials of the collimator in the case of fast neutron radiography. The presented facilities have been simulated for a wide range of parameter values to characterize neutron radiography using the MCNP4B Monte Carlo code.
