Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 4,   Pages 486-490 doi: 10.1007/s11705-010-0509-6

Abstract: density profile of the gas-liquid-solid mixture in a slurry bubble column was measured by gamma-ray attenuationSeveral measures for improving measurement precision were presented based on the discussion on attenuationfound that the response frequency and the ray intensity should be as high as possible to improve the measurementthat the density in the column decreases with the increase of column height, which indicates that the measurementby gamma-ray attenuation is reasonable.
