Some industrial applications of gamma-ray tomography

Various tomographic techniques such as electrical capacitance, electrical resistivity, MRI, X-ray/gamma-ray tomography have been reviewed with special emphasis on applicability for the industrial set-ups are discussed. It was found that gamma-ray tomography is most suitable technique which could be used for industrial set-ups. Gamma-ray tomography was also applied for variety of industrial equipment, such as paddle bed dryer, packed distillation column, to explore the possibility of their use for diagnosis of unidentified problems. From the preset work it is recommended to undertake tomographic scanning of critical equipments periodically to enhance the efficiency and reduce possible downtime.
