Studies are described on spark counting of tracks directly induced by fast neutrons in the cellulose nitrate detector, LR-115 (Type II). The spark counting for the detector ir-radiated by neutrons from an Am-Be source was performed under different etching condi-tions and different sample setting in the spark counter used in the experiment. The char-acteristic curves of spark counts vs. neutron fluence was determined, and sensitivity of the detector treated by the method was obtained to be 3×10<SUP>-7</SUP> for the fluence between 1×10<SUP>7</SUP>and 2×10<SUP>9</SUP> n/cm<SUP>2</SUP> in the most adequate condition. The reproducibility of this method was estimated to be 13%.
