In this paper, a new tomographic scan method with fixed installed detectors and rotating source from gamma projector was presented to diagnose the industrial plants which were impossible to be examined by conventional tomographic systems. Weight matrix calculation method which was suitable for volumetric detector and statistical iterative reconstruction method were applied for reconstructing the simulation and experimental data. Monte Carlo simulations had been performed for two kinds of phantoms. Lab scale experiment with a same condition as one of phantoms, had been carried out. Simulation results showed that reconstruction from photopeak counting measurement gave the better results than from the gross counting measurement although photopeak counting measurement had large statistical errors. Experimental data showed the similar result as Monte Carlo simulation. Those results appeared to be promising for industrial tomographic applications, especially for petrochemical industries.

국제원자력기구(IAEA)의 아시아지역에서의 원자력과학기술협력협정(RCA)은 금년으로 10년을 맞이했다. 현재, 이 협정에 따라 동남아시아 여러 나라에서는 식품조사, 방사선계측기의 보수 등의 프로젝트와 UN개발계획 (UNDP)과의 협력에 의한 공업이용프로젝트가 활발하게 진행되고 있다.
