Abstract:
In this thesis, the basic methods of Non-Destructive Testing (NDT) were discussed.
In this study, the X-ray machines used in the oil pipeline were compared to that used in medical filed.
From the comparison, it was found that, the machine used for oil pipeline needs high voltage (due to pipeline thickness) and long exposure time, while the one used for medical purpose needs low voltage (due to the nature of tissues) and short exposure time. While the radiographic films differ, and were found to, depend on the voltage used in the technique.
