The thermally stimulated luminescence (TSL) of normal and pathological urine was studied. The presence of
pathological salts leads to extinguishing of TSL intensity and to the appearance of additional stripes with maxima nearly
118 and 205K, except of characteristic stripes with the maxima nearly 173 and 260K. TSL stripes depend on urine
constituents. The comparison of TSL intensity of normal and pathological urine is carried out and energies of thermal
activation are determined for most intensive TSL stripes.
