A powerful non-destructive testing (NDT) technique is adopted to study the internal defects and elemental distribution/homogeneity and porosity of aerated brick and EPS aggregate poly brick samples. In the present study the internal defects like homogeneity, porosity, elemental distribution, EPS aggregate and aerator distributor in the test samples have been observed by the measurement of gray value/optical density of the neutron radiographic images of these samples. From this measurement it is found that the neutron intensity/optical density variation with the pixel distance of the AOI of the NR images in both expanded polystyrene (EPS) aggregate poly brick and aerated brick samples comply almost same in nature with respect to the whole AOI but individually each AOI shows different nature from one AOI to another and it confirms that the elemental distribution within a AOI is almost homogeneous. Finally it was concluded that homogeneity, elemental distribution in the EPS aggregate poly brick sample is better than that of the aerated brick sample.

Since 2019, the TITAN neutron radiography and tomography facility have been operating at the WWR-K research reactor. The experimental station is intended for a wide range of applications in various fields of science. Since the launch, several interesting works have been carried out to study the internal features of lithium-ion batteries and geophysical materials. The spatial resolution of the detector system was sufficient to visualize the internal elements of the lithium battery and to separate individual grains of the pyrite mineral in the rock sample. This paper presents the technical parameters of the experimental setup and the results of the recent applied research.
