Low limits of measuring dose are limited by self-glow of luminol solution and luminescence of unradiated samples of saccharides. The suitable concentration of luminol soolution should be 7×10,-8, mol/ml and a high ratio of signal to noise can be obtained when solution temperature is in the range of 15-25℃ The ranges suitable for dose measurement have been evaluated based on dose responce characteristic of these saccharides. Sensitivities are in this order of priorities: Trehalose, sucrose, galactose, glucose, levulose, mannose, and dose measurement dispersion change to poor according to this priorities also. Stability of lyoluminescence of the saccharides is not depended on heat treatmant of the samples.
