Abstract : This work proposes a method to deal with the problem of poor radiographic sensitivity in the in-service inspection of water-filled pipes. aRTist analytical radiographic inspection simulation tool and Monte Carlo N-Particle code are used to simulate the inspection of empty and water-filled pipes using 192Ir gamma source, and an X-ray source to characterize the radiation that reaches the film. The simulation results show that the ratio of direct radiation to scattered radiation (DSR) is responsible for the image quality. An approach to optimize the radiographic screen by using different screen materials and thicknesses to adjust the DSR was examined and the results showed prospects to improve the radiographic quality. Experiments were carried out using an X-ray machine. Empirical equivalent exposures values are used to counteract the water attenuation. The enhanced visibility of the wires of the Image Quality Indicator (IQI) indicated the success of the proposed approach of the optimized radiographic screen in mitigating the scattered radiation and thus, improving the sensitivity.
