An essential part of modern quality management system in cement production is state-of-the-art radiation measurement technologies based on methods of neutron activation, X-ray fluorescence and X-ray diffraction chemical analysis of substance. The high speed and accuracy of measuring the characteristics of raw materials and finished products can be achieved by their complex application, thereby ensuring an improving in the level of automation of cement production and the quality of cement in general. The main stages of the portlandcement production process by dry method are considered, including the keypoints of quality control of their implementation by applying mentioned radiation methods of chemical analysis of raw materials and completed product. The metrological problems of their practical implementation in continuous cement production are analyzed, in particular problems of uncertainty assessment, static and dynamic calibration and increase of accuracy of measuring systems that implement neutron activation analysis methods. Shown the directions of their improvement by the use of alternative neutron sources, methods of Monte Carlo N-Particle Transport Code for neutron activation analysis physical processes simulation and machine learning for the efficient processing of spectral characteristics of investigated substances.
