Abstract The present paper has dealt with the physical basis of X-radiation sampling technique and made systematic analysis and study of three key technical problems in X-radiation sampling: unevenness effect, matrix effect and heterogeneous mineralization effect. What is more, the paper puts forward methods and techniques to solve these problems, which were successfully used in reconnaissance, exploration and mining stages of gold, tin and copper deposits and could meet the demands of production departments.
