Prediction of photon attenuation coefficients of heavy concrete by fuzzy logic

The fuzzy logic (FL) model to determine the radiation shielding properties of concretes containing barite in the ratio of 0%, 50%, 60%, 70%, 100%, and different water-to-cement ratio (w/c) have been developed. For training of the networks in the model, w/c and barite ratio were input, while the photon attenuation coefficient was output. The FL results were compared with experimental results and correlation between experiment and FL was compared with the correlation between experiment and calculation (XCOM). It was found that the correlation between FL and experiment was better than the correlation between XCOM and experiment.
