Study on the Regularity of the Natural Gamma-Rays Attenuation in the Slurry Water

Abstract:

Gamma-ray density meter has been widely used in coal preparation plant to detect the concentration of the slurry water, but it require annual inspection, approval, and the protection of the radioactive sources causes a lot of inconvenience to the coal preparation plant. In this paper a natural mineral sand beach has been chosen as radioactive sources, which contains thorium. An experimental device has been designed to detect the concentration of the slurry water, the natural gamma-rays attenuation rules were obtained after lots of experiments in the laboratory when it passing through the different concentration of the slurry water, and the rules were proved in theory and in tests. This provides reliable basis for design of slurry water concentration measurement device.
